1. Business and Basis of Presentation

Overview

Galena Biopharma, Inc. (“we,” “us,” “our,” “Galena” or the “company”) is a biopharmaceutical company focused on developing and commercializing innovative, targeted oncology therapeutics that address major medical needs across the full spectrum of cancer care. Galena’s development portfolio ranges from mid- to late-stage clinical assets, including a robust immunotherapy program led by NeuVax™ (nelipepimut-S) currently in an international, Phase 3 clinical trial. The company’s commercial drugs include Abstral ^® (fentanyl) Sublingual Tablets and Zuplenz ^® (ondansetron) Oral Soluble Film. Collectively, our clinical and commercial strategy focuses on identifying and advancing therapeutic opportunities to improve cancer care, from direct treatment of the disease to the reduction of its debilitating side-effects.

Novel Cancer Immunotherapies

Our targeted cancer immunotherapy approach is based upon preventing recurrence of cancer, which is becoming increasingly important as the number of cancer survivors continues to grow. Once a patient’s tumor becomes metastatic, the outcome is most often fatal, making the prevention of recurrence a potentially critical component of overall patient care. Our programs primarily target patients in the adjuvant (after-surgery) setting who have relatively healthy immune systems, but may still have undetected minimal residual disease.

Our therapies utilize immunologically active peptides combined with the immune adjuvant, recombinant human granulocyte macrophage-colony stimulating factor (rhGM-CSF), and work by harnessing the patient’s own immune system to target, seek out and attack any residual cancer cells. Using peptide immunogens has many potential clinical advantages, including a favorable safety profile, since these drugs may lack the toxicities typical of most cancer therapies. They also have the potential to evoke long-lasting protection through activation of the immune system through an intradermal mode of delivery. We are currently engaged in multiple clinical trials with NeuVax™ (nelipepimut-S) and GALE-301, or Folate Binding Protein (FBP), targeting the prevention of recurrence in breast, gastric, ovarian and endometrial cancers.

NeuVax™ (nelipepimut-S)

NeuVax™ (nelipepimut-S), our lead product candidate, is a targeted cancer immunotherapy and is being developed for the prevention of cancer recurrence in human epidermal growth factor receptor (HER2) expressing cancers. NeuVax is the immunodominant nona-peptide derived from the extracellular domain of the HER2 protein, a well-established target for therapeutic intervention in breast and gastric carcinomas. The NeuVax vaccine is combined with GM-CSF for injection under the skin, or intradermal administration. Data has shown that an increased presence of circulating tumor cells (CTCs) may be a predictive factor of Disease Free Survival (DFS) and Overall Survival (OS) - suggesting a dormancy of isolated micrometastases, which, over time, may lead to recurrence. After binding to the HLA A2, A3, A24 or A26 proteins on antigen presenting cells, the nelipepimut-S sequence stimulates specific cytotoxic T lymphocyte (CTLs). These activated CTLs recognize, neutralize and destroy, through cell lysis, HER2 expressing cancer cells, including undetected occult cancer cells and micrometastatic foci. The nelipepimut immune response can also generate CTLs to other immunogenic peptides through inter- and intra-antigenic epitope spreading.

We have multiple trials currently ongoing for NeuVax. For our global pivotal, fully enrolled, Phase 3 PRESENT ( P revention of R ecurrence in E arly- S tage, Node-Positive Breast Cancer with Low to Intermediate HER2 E xpression with NeuVax T reatment) trial, NeuVax is targeting the 30,000-40,000 of the 230,000 female breast cancer patients annually diagnosed in the U.S. who are at a higher risk of their breast cancer recurring, which we refer to as “disease recurrence,” after achieving “no evidence of disease” (NED) status, (or becoming a “survivor”) with standard-of-care therapy (surgery, chemotherapy, radiation). These high-risk patients have a particular molecular signature and disease status: HER2 IHC 1+/2+ (oncoprotein associated with aggressive tumor growth), node positive (disease present in the axillary lymph nodes prior to surgery), and HLA A2/A3 (human leukocyte antigen from A2/A3 patients who have the same loci of genes which represents approximately 65% of population). NeuVax has also been shown to bind to A24 and A26 which represents an additional 10-15% of the population in the U.S., but importantly, represents up to 70% of the population in Japan. Up to 25% of resectable, node-positive breast cancer patients, having no radiographic evidence of disease following surgery and adjuvant chemo/radiation therapy, are expected to relapse within three years following diagnosis. The prognosis upon recurrence is very poor. These cancer patients presumably still had isolated, undetected tumor CTCs that led to a recurrence of cancer in the breast (local recurrence) or in another location (metastatic disease).

We currently have a number of ongoing or planned clinical trials designed to expand the clinical and geographic footprint of NeuVax:

•

Phase 3 Ongoing: Our Phase 3 PRESENT ( P revention of R ecurrence in E arly- S tage, Node-Positive Breast Cancer with Low to Intermediate HER2 E xpression with NeuVax T reatment) study has completed enrollment of 758 patients with HER2 1+ and 2+ under a Special Protocol Assessment (SPA) granted by the U.S. Food and Drug Administration (FDA). The multinational, multicenter, randomized, double-blinded PRESENT trial is fully enrolled with trial sites in North America, Western and Eastern Europe, and Israel. Additional information on the study can be found at www.neuvax.com .


•	Phase 2b Ongoing: A randomized, multicenter, investigator-sponsored, 300 patient Phase 2b clinical trial is enrolling HER2 1+/2+ node-positive and high-risk node-negative HLA A2/A3/A24/A26 breast cancer patients to study NeuVax in combination with trastuzumab (Herceptin ^® ; Genentech/Roche) in the adjuvant setting. This trial is partially funded by Genentech/Roche.

•

Phase 2 Ongoing: An investigator-sponsored trial is ongoing to study NeuVax in combination with Herceptin. The study will enroll 100 patients who are neoadjuvantly treated node positive and negative HER2 IHC 3+ patients, not achieving a pathological complete response (pCR) or adjuvantly treated node positive HER2 IHC 3+ patients. Partial funding for this trial comes from the Department of Defense (DoD) through the Congressionally Directed Medical Research Program (CDMRP) which is funded through specific requests from individual members of Congress that are part of the Defense Appropriations Act. Funds are "set aside" (obligated) in entirety at the time of assistance agreement award. The grant was awarded under a Breast Cancer Research Program (BCRP) Breakthrough Award given to the lead investigator for the trial.


•	Phase 2 Planned: In January 2014, we partnered with Dr. Reddy’s Laboratories, Ltd. in India for the commercialization of NeuVax in that region. Dr. Reddy’s is responsible for managing a Phase 2 gastric cancer trial of NeuVax in India in patients that express any level of HER2 (1+, 2+, and 3+). The trial is expected to initiate in 2016.

GALE-301 (folate binding protein or FBP)

Our second immunotherapy product candidate, GALE-301, targets folate binding protein receptor-alpha, a well-validated therapeutic target, which is highly over-expressed (20-80 fold) in ovarian, endometrial and breast cancers. GALE-301 is an immunogenic peptide and can stimulate CTLs to recognize and destroy FBP-expressing cancer cells. GALE-301 consists of an FBP peptide combined with GM-CSF, and is currently in a Phase 2a clinical trial for the prevention of recurrence in patients with ovarian and endometrial cancers. Current treatments for these diseases are principally with chemotherapeutic agents and patients suffer a high recurrence rate; and, most patients relapse with an extremely poor prognosis. Although not powered for efficacy, promising preliminary results from the Phase 2a clinical trial of GALE-301 were presented in May 2015 at the American Society of Clinical Oncology conference and demonstrated the estimate for disease free survival at two years is 85.7% (1000 mcg dose group) vs. 19.2% for the control group (p = 0.09), for a 78% reduction in relative risk of recurrence, and that the agent was well-tolerated with primarily Grade 1 and 2 toxicities and elicited a strong in vivo immune response. We expect to present a more mature data set from the Phase 2a trial this Fall at the European Society for Medical Oncology European Cancer Congress 2015.

Hematology

GALE-401 (anagrelide controlled release (CR))

In January 2014, we announced the acquisition of the worldwide rights to anagrelide controlled release (CR), which we renamed GALE-401, through our acquisition of Mills Pharmaceuticals, LLC. GALE-401 contains the active ingredient anagrelide (Agrylin ^® , Shire Pharmaceuticals), an FDA-approved product, for the treatment of patients with myeloproliferative neoplasms (MPNs) to lower abnormally elevated platelet levels. The currently available immediate release (IR) version of anagrelide causes adverse events that are believed to be dose and plasma concentration dependent. Therefore, reducing the maximum concentration (C _max ) is hypothesized to reduce the side effects, but preserve efficacy.

Multiple Phase 1 studies in 98 healthy subjects have shown GALE-401 reduces the C _max of anagrelide following oral administration, appears to be well tolerated at the doses administered, and to be capable of reducing platelet levels. The Phase 1 program provided the desired PK (pharmacokinetic) profile to enable the initiation of the ongoing Phase 2 proof-of-concept trial. The Phase 2, open label, single arm trial enrolled 18 patients in the United States for the treatment of thrombocytosis, or elevated platelet counts in patients with MPNs. Phase 2 top-line safety and efficacy data was presented in June 2015 at the European Hematology Association 20th Congress. We expect to present a more mature data set from the Phase 2 trial later this year. Based on a regulatory meeting with the FDA, Galena believes a 505(b)(2) regulatory filing is an acceptable pathway for development and potential approval of GALE-401, with the reference drug Agrylin ^® (anagrelide; Shire Pharmaceuticals).

Zuplenz ^® (ondansetron) Oral Soluble Film

In July 2014 we licensed our second commercial product, Zuplenz ^® (ondansetron) Oral Soluble Film, from MonoSol Rx, LLC, which we launched on July 29, 2015. Zuplenz is approved by the FDA in adult patients for the prevention of highly and moderately emetogenic chemotherapy-induced nausea and vomiting (CINV), radiotherapy-induced nausea and vomiting (RINV), and post-operative nausea and vomiting (PONV). Zuplenz is also approved in pediatric patients treated with moderately emetogenic CINV. Nausea and vomiting are two of the most common side-effects experienced by post-surgery patients and patients receiving chemotherapy or radiation. It is estimated that up to 90% of chemotherapy and up to 80% of radiotherapy patients will experience CINV and RINV, respectively.

The active pharmaceutical ingredient in Zuplenz, ondansetron, belongs to a class of medications called serotonin 5-HT ₃ receptor antagonists and works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting. Ondansetron is the most widely prescribed drug in this class of anti-emetics, and used broadly across the oncology spectrum. Zuplenz is clinically bioequivalent to ondansetron orally disintegrating tables (ODT) with a safety profile equivalent to ondansetron.

Zuplenz utilizes MonoSol’s proprietary PharmFilm ^® technology, an oral soluble film that dissolves on the tongue in less than 30 seconds. Zuplenz eliminates the burden of swallowing pills during periods of emesis, may be advantageous for patients with oral irritation, and may increase patient adherence and the patient's ability to keep the medication down without vomiting. MonoSol will exclusively manufacture Zuplenz for us for sale in the U.S. through our commercial organization.

Basis of Presentation and Significant Accounting Policies

The accompanying consolidated financial statements included herein have been prepared by Galena pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Unless the context otherwise indicates, references in these notes to the “company,” “we,” “us” or “our” refer to Galena, our wholly owned subsidiary, Apthera, Inc., or “Apthera,” and our wholly owned subsidiary, Mills Pharmaceuticals, LLC or "Mills."

Uses of Estimates in Preparation of Financial Statements — The preparation of these consolidated financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates.

Principles of Consolidation — The consolidated financial statements include the accounts of Galena and its wholly owned subsidiaries. All material intercompany accounts have been eliminated in consolidation.

Reclassifications — Certain prior year amounts have been reclassified to conform to current year presentation. These reclassifications had no effect on net loss per share.

Cash and Cash Equivalents — The company considers all highly liquid debt instruments with an original maturity of 90 days or less to be cash equivalents. Cash equivalents consist primarily of amounts invested in money market accounts and demand deposits.

Restricted Cash — Restricted cash consists of certificates of deposit on hand with the company’s financial institutions as collateral for its corporate credit cards.

Fair Value of Financial Instruments — The carrying amounts reported in the balance sheet for cash equivalents, accounts receivable, accounts payable, and capital leases approximate their fair values due to their short-term nature and market rates of interest.

Accounts Receivable - The company maintains credit limits for all customers based upon several factors, including but not limited to financial condition and stability, payment history, published credit reports and use of credit references. Management performs analysis to evaluate accounts receivables to ensure recorded amounts reflect estimated net realizable value. An allowance for doubtful accounts is established based on the Company's best estimate of the amount of probable credit losses in the Company's accounts receivable. As of June 30, 2015 and December 31, 2014 the allowance for doubtful accounts was $160,000 .

Inventories — Inventories are stated at the lower of cost or market value and are determined using the first-in, first-out ("FIFO") method. Inventories consist of work-in-process and finished goods of our commercial products. The company has entered into manufacturing and supply agreements for the manufacture and final packaging of Abstral and Zuplenz finished goods. As of June 30, 2015 , the company had inventories of $1,426,000 , consisting of $1,264,000 of work-in-process and $162,000 of finished goods. As of December 31, 2014 , the company had inventories of $655,000 consisting of $455,000 of work-in-process and $200,000 of finished goods.

Equipment and Furnishings — Equipment and furnishings are stated at cost and depreciated using the straight-line method based on the estimated useful lives (generally three to five years) of the related assets.

Goodwill and Intangible Assets — Goodwill and indefinite-lived intangible assets are not amortized but are tested annually for impairment at the reporting unit level, or more frequently if events and circumstances indicate impairment may have occurred. Factors the company considers important that could trigger an interim review for impairment include, but are not limited to, the following:

• Significant changes in the manner of its use of acquired assets or the strategy for its overall business;

• Significant negative industry or economic trends;

• Significant decline in stock price for a sustained period; and

• Significant decline in market capitalization relative to net book value.

Goodwill and other intangible assets with indefinite lives are evaluated for impairment first by a qualitative assessment to determine the likelihood of impairment. If it is determined that impairment is more likely than not, the company will then proceed to the two step impairment test. The first step is to compare the fair value of the reporting unit to the carrying amount of the reporting unit. If the carrying amount exceeds the fair value, a second step must be followed to calculate impairment. Otherwise, if the fair value of the reporting unit exceeds the carrying amount, the goodwill is not considered to be impaired as of the measurement date. In its review of the carrying value of the goodwill for its single reporting unit and its indefinite-lived intangible assets, the company determines fair values of its goodwill using the market approach, and its indefinite-lived intangible assets using the income approach.

Intangible assets not considered indefinite-lived are reviewed for impairment when facts or circumstances suggest that the carrying value of these assets may not be recoverable. The company’s policy is to identify and record impairment losses, if necessary, on intangible assets when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts.

The company performed its review for impairment using the qualitative assessment for both goodwill and indefinite-lived intangible assets, as well as assets not considered to be indefinite-lived, and has determined that there has been no impairment to these assets as of June 30, 2015 .

Revenue Recognition - The company recognizes revenue from the sale of Abstral. No revenue has been recorded from the sale of Zuplenz as of June 30, 2015 . Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred and title has passed, (iii) the price is fixed or determinable and (iv) collectability is reasonably assured.

We sell Abstral product in the United States to wholesale pharmaceutical distributors and retail pharmacies, or our "customers," subject to rights of return. We recognize Abstral product sales at the time title transfers to our customer, and provide allowances for estimated future product returns, prompt pay discounts, wholesaler discounts, rebates, chargebacks, patient assistance program benefits and other deductions as needed. The company is required to make significant judgments and estimates in determining some of these allowances. If actual results differ from its estimates, the company will be required to make adjustments to these allowances in the future.

Returns - The company estimates future returns based on historical return information, as well as information regarding prescription information and sell-through trends, in relation to the estimated amount of product in the sales channels and product expiration dates. The allowance for returns is recorded as a reduction to revenue in the period in which the revenue is recognized, with a corresponding allowance against accounts receivable.

Prompt Pay Discounts - As an incentive for prompt payment, the company offers a cash discount to customers, which is generally 2% of gross sales. The company expects that all customers will comply with the contractual terms to earn the discount. The company records prompt pay discounts as a reduction to revenue in the period in which the revenue is recognized, with a corresponding allowance against accounts receivable.

Wholesaler Discounts - The company offers discounts on sales to wholesalers and distributors based on contractually determined rates. The company accrues the discount as a reduction of receivables due from the wholesalers upon shipment to the respective wholesale distributors and retail pharmacies and recognizes the discount as a reduction of revenue in the same period the related revenue is recognized.

Rebates - The company participates in certain rebate programs, which provide discounted prescriptions to members of certain managed care organizations, group purchasing organizations and specialty pharmacies. Under these rebate programs, the company pays the rebates generally two to three months after the end of the quarter in which prescriptions subject to the rebate are filled. The company estimates and accrues these rebates based on current contract prices, historical and estimated future percentages of product sold to qualifying member pharmacies and estimated levels of inventory in the distribution channel. Rebates are recognized as a reduction to revenue in the period that the related revenue is recognized, with a corresponding liability in accrued expenses and other current liabilities.

Chargebacks - The company provides discounts primarily to authorized users of the Federal Supply Schedule (FSS) of the General Services Administration under an FSS contract negotiated by the Department of Veterans Affairs and various organizations under Medicaid or Medicare contracts and regulations. These entities purchase products from the wholesale distributors at a discounted price, and the wholesale distributors then charge back to the company the difference between the current retail price and the price the entity paid for the product. The company estimates and accrues chargebacks based on estimated wholesaler inventory levels, current contract prices and historic chargeback activity. Chargebacks are recognized as a reduction of revenue in the period the related revenue is recognized, with a corresponding allowance against accounts receivable.

Patient Assistance Programs - The company offers discount card programs to eligible patients for Abstral in which those patients receive discounts on their Abstral prescriptions that are reimbursed by the company. The company estimates the total amount that will be recognized based on a percentage of actual redemption applied to inventory in the distribution and retail channel and recognizes the discount as a reduction of revenue and as an other current liability (see Note 4) in the same period the related revenue is recognized.

Acquisitions and In-Licensing — For all in-licensed products and technologies, we perform an analysis to determine whether we hold a variable interest or a controlling financial interest in a variable interest entity. On the basis of our interpretations and conclusions, we determine whether the acquisition falls under the purview of variable interest entity accounting and if so, consider the necessity to consolidate the acquisition. As of June 30, 2015 , we determined there were no variable interest entities required to be consolidated.

We also perform an analysis to determine if the assets and liabilities acquired in an acquisition qualify as a "business." The excess of the purchase price over the fair value of the net assets acquired can only be recognized as goodwill in a business combination. The Company completes its valuation analysis no later than twelve months from the date of the acquisition.

Contingent Purchase Price Consideration — Contingent consideration in business combinations is recorded at the estimated fair value as of the acquisition date. The fair value of the contingent consideration is re-measured at each reporting period with any adjustments in fair value included in our consolidated statement of comprehensive loss.

Patents and Patent Application Costs — Although the company believes that its patents and underlying technology have continuing value, the amount of future benefits to be derived from the patents is uncertain. Patent costs are, therefore, expensed as incurred.

Share-based Compensation — The company follows the provisions of the FASB ASC Topic 718, “ Compensation — Stock Compensation” (“ASC 718”), which requires the measurement and recognition of compensation expense for all stock-based payment awards made to employees, non-employee directors, and consultants, including stock options and warrants. Stock compensation expense based on the grant date fair value estimated in accordance with the provisions of ASC 718 is recognized as an expense over the requisite service period.

For stock options and warrants granted as consideration for services rendered by non-employees, the company recognizes compensation expense in accordance with the requirements of FASB ASC Topic 505-50 (“ASC 505-50”), “ Equity Based Payments to Non- Employees .” Non-employee option and warrant grants that do not vest immediately upon grant are recorded as an expense over the vesting period. At the end of each financial reporting period prior to vesting, the value of these options and warrants, as calculated using the Black-Scholes option-pricing model, is re-measured using the fair value of the company’s common stock and the non-cash compensation recognized during the period is adjusted accordingly. Since the fair market value of options and warrants granted to non-employees is subject to change in the future, the amount of the future compensation expense will include fair value re-measurements until the stock options are fully vested.

Research and Development Expenses — Research and development costs are expensed as incurred. Included in research and development costs are wages, benefits and other operating costs, facilities, supplies, external services and overhead related to our research and development departments, and clinical trial expenses.

Clinical trial expenses include direct costs associated with contract research organizations (CROs), as well as patient-related costs at sites at which our trials are being conducted.

Direct costs associated with our CROs are generally payable on a time and materials basis, or when certain enrollment and monitoring milestones are achieved. Expense related to a milestone is recognized in the period in which the milestone is achieved or in which we determine that it is more likely than not that it will be achieved.

The invoicing from clinical trial sites can lag several months. We accrue these site costs based on our estimate of upfront set-up costs upon the screening of the first patient at each site, and the patient related costs based on our knowledge of patient enrollment status at each site.

Income Taxes — The company recognizes liabilities or assets for the deferred tax consequences of temporary differences between the tax basis of assets or liabilities and their reported amounts in the financial statements in accordance with FASB ASC 740-10, “ Accounting for Income Taxes” (“ASC 740-10”). These temporary differences will result in taxable or deductible amounts in future years when the reported amounts of the assets or liabilities are recovered or settled. ASC 740-10 requires that a valuation allowance be established when management determines that it is more likely than not that all or a portion of a deferred asset will not be realized. The company evaluates the realizability of its net deferred income tax assets and valuation allowances as necessary, at least on an annual basis. During this evaluation, the company reviews its forecasts of income in conjunction with other positive and negative evidence surrounding the realizability of its deferred income tax assets to determine if a valuation allowance is required. Adjustments to the valuation allowance will increase or decrease the company’s income tax provision or benefit. The recognition and measurement of benefits related to the company’s tax positions requires significant judgment, as uncertainties often exist with respect to new laws, new interpretations of existing laws, and rulings by taxing authorities. Differences between actual results and the company’s assumptions or changes in the company’s assumptions in future periods are recorded in the period they become known.

There was no income tax expense or benefit for the three and six months periods ended June 30, 2015 and 2014. We continue to maintain a full valuation allowance against our net deferred tax assets.

Concentrations of Credit Risk — Financial instruments that potentially subject the company to significant concentrations of credit risk consist principally of cash and cash equivalents. The company maintains cash balances in several accounts with two banks, which at times are in excess of federally insured limits. As of June 30, 2015 , the company’s cash equivalents were invested in money market mutual funds. The company’s investment policy does not allow investment in any debt securities rated less than “investment grade” by national ratings services. The company has not experienced any losses on its deposits of cash and cash equivalents. The company maintains significant cash and cash equivalents at two financial institutions that are in excess of federally insured limits.

Comprehensive Loss — Comprehensive loss consists of our net loss, with no other comprehensive income items for the periods presented.

2. Business Combinations

On July 17, 2014 the Company entered into a definitive license and supply agreement with MonoSol for the U.S. commercial rights to Zuplenz ^® (ondansetron) Oral Soluble Film (Zuplenz), an FDA approved product. The transaction was accounted for as a business combination under the acquisition method of accounting based on Accounting Standards Codification 805, " Business Combinations. " Accordingly, the assets acquired and liabilities assumed were recorded at fair value. As of the issuance date of the condensed consolidated financial statements for the quarter ended June 30, 2015, the Company finalized the valuation of the acquired assets and liabilities for the transaction. Specifically, more complete information for credit memos for expiring channel inventory and the anticipated gross-to-net deductions on the replacement inventory was provided in order to finalize the business combination accounting.

The following table summarizes the purchase price consideration and allocation of purchase price:



	Total Acquisition Date Fair Value
Purchase price consideration:
Cash and cash equivalents	$	3,556
Common stock	2,482
Liabilities assumed:
Contingent consideration	240
Credit memos for expiring channel inventory	1,995
Total consideration	$	8,273

Asset acquired:
Zuplenz rights	$	8,101
Goodwill	172
Fair value of assets acquired	$	8,273

The above contingent consideration represents a risk adjusted net present value relating to cash payments on achievement of certain milestones.

3. Fair Value Measurements

The company follows ASC 820, “Fair Value Measurements and Disclosures,” (“ASC 820”) for the company’s financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and are re-measured and reported at fair value at least annually using a fair value hierarchy that is broken down into three levels. Level inputs are defined as follows:

Level 1 — quoted prices in active markets for identical assets or liabilities.

Level 2 — other significant observable inputs for the assets or liabilities through corroboration with market data at the measurement date.

Level 3 — significant unobservable inputs that reflect management’s best estimate of what market participants would use to price the assets or liabilities at the measurement date.

The company categorized its cash equivalents as Level 1. The valuations for Level 1 were determined based on a “market approach” using quoted prices in active markets for identical assets. Valuation of these assets does not require a significant degree of judgment. The company categorized its warrants potentially settleable in cash as Level 2 inputs. The warrants are measured at market value on a recurring basis and are being marked to market each quarter-end until they are completely settled. The warrants are valued using an appropriate pricing model, using assumptions consistent with our application of ASC 718. The contingent purchase price consideration is categorized as Level 3 inputs and is measured at its estimated fair value on a recurring basis and is adjusted at each quarter-end until it is completely settled. The contingent purchase price consideration is valued based on the expected timing of milestones, the expected probability of success for each milestone and discount rates based on a corporate debt interest rate index publicly issued.

The Loan payment terms include 12 months of interest-only payments at the fixed coupon rate of 8.45% , followed by 30 months of amortization of principal and interest until maturity in November 2016. In connection with the Loan, we paid the lender a 1% cash facility fee and a 5.5% cash final payment and granted to the lenders seven -year warrants to purchase up to 182,186 shares of our common stock at an exercise price of $2.47 , which equaled a 20 -day average market price of our common stock prior to the date of the grant.

6. Legal Proceedings, Commitments and Contingencies

Legal Proceedings

In re Galena Biopharma, Inc. Stockholder Derivative Litigation and In Re Galena Biopharma, Inc. Derivative Litigation

On January 23, 2015, U.S. District Court for the District of Oregon heard argument on the defendants’ motion to stay and motion to dismiss. On February 4, 2015, the District Court granted in part the motion to stay by staying any discovery until the ruling on the motion to dismiss. On August 5, 2015, the District Court issued its decision by denying in part and granting in part defendants’ motion to dismiss and granting plaintiffs leave to file an amended complaint. The court had stayed the derivative proceeding pending the outcome of the motion to dismiss in the securities class action case.

On August 4, 2105, plaintiffs in the voluntarily dismissed Delaware derivative action have filed a motion seeking to file under seal a derivative complaint in the District Court.

We intend to vigorously defend against and seek resolution to the foregoing claims. As of June 30, 2015, we have not recorded any liabilities with respect to the claims in our consolidated financial statements. We believe that claims are covered under our liability insurance, and we have notified our insurance carriers of the claims. The insurers have responded by requesting additional information and by reserving their rights under the policies, including the rights to deny coverage under various policy exclusions. Subject to their reservation of rights, we are being reimbursed by our insurer for substantially all legal fees relating to our defense of the claims. We have entered into certain undertaking agreements with our directors related to the litigation by which we have agreed to advance reasonable legal fees and costs for the litigation under certain conditions.

SEC Investigation

We are aware that the Securities and Exchange Commission (SEC) is investigating certain matters relating to the use of certain outside investor-relations professionals by us and other public companies. We have been in contact with the SEC staff through our counsel and are cooperating with the investigation.

ANDA Litigation

By letter dated December 23, 2014, Orexo and we received a Paragraph IV certification notice (Notice Letter) regarding an Abbreviated New Drug Application (ANDA) submitted to the FDA by Actavis Laboratories FL, Inc. (Actavis) requesting approval to engage in the m an ufacture , use or sale of generic versions of the Abstral sublingual t a blets Eq 0.1 mg base , Eq 0.2 m g base , E q 0.3 mg base, Eq 0.4 mg base , Eq 0.6 mg base and Eq 0.8 mg base. In the Notice Letter, Actavis contends that the patents held by Orexo for Abstral that are listed in the Orange Book (U.S. Patents 6,759,059, 6,761,910 and 7,910,132, which cover compositions, formulations and methods of using Abstral and which expire in September 2019) and which are licensed to us under the Orexo License Agreement, are invalid, unenforceable and/or will not be infringed by the manufacture, use, or sale of the product set forth in the ANDA. On February 4, 2015, Orexo filed a patent infringement lawsuit in the U.S. District Court for the District of New Jersey against Actavis Laboratories Fl, Inc., Andrx Corporation, Actavis, Inc., and Actavis Pharma, Inc. All of the defendants except Actavis Laboratories FL, Inc. were subsequently dismissed. Actavis has filed an answer and counterclaim. The lawsuit claims infringement of the three patents. Orexo filed the lawsuit within 45 days from the receipt of the Notice Letter and under the Hatch-Waxman Act, the final FDA approval of Actavis’ ANDA will be stayed up to 30 months from the date of receipt of the Notice Letter.

A scheduling conference was held on July 9, 2015, in the District Court and on July 10, 2015, the District Court issued a pre-trial scheduling order. The parties are now engaged in written discovery.

We are obligated under Orexo License Agreement to pay for 88% of the legal costs of the patent infringement lawsuit. We intend to work with Orexo to continue to vigorously enforce intellectual property rights related to the Abstral product.

Commitments

The company acquires assets still in development and enters into research and development arrangements with third parties that often require milestone and royalty payments based on the progress of the asset through development stages. Milestone payments may be required, for example, upon approval of the product for marketing by a regulatory agency. In certain agreements, the company is required to make royalty payments based upon a percentage of the sales.

These arrangements may be material individually, and in the unlikely event that milestones for multiple products covered by these arrangements were reached in the same period, the aggregate charge to expense could be material to the results of operations. In addition, these arrangements often give the company the discretion to unilaterally terminate development of the product, which the company might do for clinical, business or other reasons, which would allow the company to avoid making the contingent payments.

The company applies the disclosure provisions FASB ASC Topic 460 (“ASC 460”), “ Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others ”, to its agreements that contain guarantee or indemnification clauses. The company provides (i) indemnifications of varying scope and size to certain investors and other parties for certain losses suffered or incurred by the indemnified party in connection with various types of third-party claims and (ii) indemnifications of varying scope and size to officers and directors against third party claims arising from the services they provide to us. These indemnifications give rise only to the disclosure provisions of ASC 460. To date, the company has not incurred costs as a result of these obligations and does not expect to incur material costs in the future. Accordingly, the company has not accrued any liabilities in its financial statements related to these indemnifications.

In addition to LPC’s initial purchase of our common stock under the purchase agreement, during the first quarter of 2015, we received net proceeds of $4.4 million from LPC’s subsequent purchases of a total of 2.7 million shares of our common stock, excluding the commitment fee shares.

At Market Issuance Sales Agreements - On May 24, 2013 the Company entered into At Market Issuance Sales Agreements (ATM) with MLV & Co. LLC and Maxim Group LLC (the Agents). From time to time during the term of the ATM, we may issue and sell through the Agents, shares of our common stock, and the Agents collect a fee equal to 3% of the gross proceeds from the sale of shares, up to a total limit of $20 million in gross proceeds. The ATM is available to the company until it is terminated by the Agents or the company. During the first quarter of 2015, we received $2.3 million in net proceeds from the sale of 1.4 million shares of our common stock through the ATM. There were no sales of our common stock under the ATM during the three months ended June 30, 2015 or during the three and six months ended June 30, 2014.

Expiration	March 2020	September 2018	December 2017	April 2017	March 2016	March 2016	Varies 2014-2020

Warrants consist of warrants potentially settleable in cash, which are liability-classified warrants, and equity-classified warrants.

Warrants classified as liabilities

Liability-classified warrants consist of warrants to purchase common stock issued in connection with equity financings in March 2015, September 2013, December 2012, April 2011, March 2011, and March 2010. These warrants are potentially settleable in cash and were determined not to be indexed to our common stock.

The estimated fair value of outstanding warrants accounted for as liabilities is determined at each balance sheet date. Any decrease or increase in the estimated fair value of the warrant liability since the most recent balance sheet date is recorded in the condensed consolidated statement of comprehensive loss as other income (expense). The fair value of the warrants is estimated using an appropriate pricing model with the following inputs:



	As of June 30, 2015
	March 2015 Warrants			September 2013 Warrants			December 2012 Warrants			April 2011 Warrants			March 2011 Warrants			March 2010 Warrants
Strike price	$	2.08		$	2.50		$	1.83		$	0.65		$	0.65		$	2.02
Expected term (years)	4.72			3.22			2.48			1.81			0.68			0.74
Volatility %	72.98		%	75.59		%	72.00		%	77.03		%	63.12		%	64.81		%
Risk-free rate %	1.54		%	1.08		%	0.82		%	0.57		%	0.17		%	0.19		%



	As of December 31, 2014
	September 2013 Warrants			December 2012 Warrants			April 2011 Warrants			March 2011 Warrants			March 2010 Warrants
Strike price	$	2.50		$	1.90		$	0.65		$	0.65		$	2.15
Expected term (years)	3.72			2.98			2.31			1.18			1.24
Volatility %	75.60		%	76.85		%	78.24		%	77.38		%	77.12		%
Risk-free rate %	1.30		%	1.09		%	0.80		%	0.32		%	0.35		%

The expected volatility assumptions are based on the company's implied volatility in combination with the implied volatilities of similar publicly traded entities. The expected life assumption is based on the remaining contractual terms of the warrants. The risk-free rate is based on the zero coupon rates in effect at the time of valuation. The dividend yield used in the pricing model is zero, because the company has no present intention to pay cash dividends.

Warrants classified as equity

Equity-classified warrants consist of warrants issued in connection with consulting services provided to us. Additionally, on May 8, 2013 as a part of our Loan financing, we granted Oxford Financial LLC warrants to purchase up to 182,186 shares of common stock at an exercise price of $2.47 , which equaled to the 20 -day average market price of our common stock prior to the date of the grant. The warrants were valued using an appropriate pricing model as described in Note 9, below. The fair value assumptions for the grant included a volatility of 75.34% , expected term of seven years, risk-free rate of 1.20% , and a dividend rate of 0.00% . The fair value of the warrants granted was $1.93 per share. These warrants are recorded in equity at fair value upon issuance, and not as liabilities, and are not subject to adjustment to fair value in subsequent reporting periods.

9. Stock-Based Compensation

Options to Purchase Shares of Common Stock — The company follows the provisions ASC 718, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees, non-employee directors, including employee stock options. Stock compensation expense based on the grant date fair value estimated in accordance with the provisions of ASC 718 is recognized as an expense over the requisite service period.

For stock options and warrants granted in consideration for services rendered by non-employees, the company recognizes compensation expense in accordance with the requirements of ASC Topic 505-50. Non-employee option and warrant grants that do not vest immediately upon grant are recorded as an expense over the vesting period. At the end of each financial reporting period prior to vesting, the value of these options and warrants, as calculated using the Black-Scholes option-pricing model, is re-measured using the fair value of the company’s common stock and the non-cash compensation recognized during the period is adjusted accordingly. Since the fair market value of options and warrants granted to non-employees is subject to change in the future, the amount of the future compensation expense will include fair value re-measurements until the stock options and warrants are fully vested.

The following table summarizes the components of stock-based compensation expense in the condensed consolidated statements of comprehensive loss for the three and six months ended June 30, 2015 and 2014, respectively (in thousands):



	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014
Research and development	$	93	$	187	$	170	$	347

The company uses the Black-Scholes option-pricing model and the following weighted-average assumptions to determine the fair value of all its stock options granted:



	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014
Risk free interest rate	1.69	%	—	%	1.50	%	2.06	%
Volatility	73.32	%	—	%	74.20	%	78.53	%
Expected lives (years)	5.76		0		6.09		6.25
Expected dividend yield	0.00	%	0.00	%	0.00	%	0.00	%

The weighted-average fair value of options granted during the three and six months ended June 30, 2015 were $1.09 per share and $1.14 per share, respectively.

The company’s expected common stock price volatility assumption is based upon the company's own implied volatility in combination with the implied volatility of a basket of comparable companies. The expected life assumptions for employee grants were based upon the simplified method provided for under ASC 718-10, which averages the contractual term of the company’s options of ten years with the average vesting term of four years for an average of six years . The expected life assumptions for non-employees were based upon the contractual term of the option. The dividend yield assumption is zero, because the company has never paid cash dividends and presently has no intention to do so. The risk-free interest rate used for each grant was also based upon prevailing short-term interest rates. The company has estimated an annualized forfeiture rate of 15% for options granted to its employees, 8% for options granted to senior management and zero for non-employee directors. The company will record additional expense if the actual forfeitures are lower than estimated and will record a recovery of prior expense if the actual forfeiture rates are higher than estimated.

As of June 30, 2015 , there was $5,582,000 of unrecognized compensation cost related to outstanding options that is expected to be recognized as a component of the company’s operating expenses over a weighted-average period of 2.54 years.

As of June 30, 2015 , an aggregate of 26,500,000 shares of common stock were reserved for issuance under the company’s 2007 Incentive Plan, including 11,411,000 shares subject to outstanding common stock options granted under the plan and 10,066,000 shares available for future grants. The administrator of the plan determines the times when an option may become exercisable. Vesting periods of options granted to date have not exceeded four years . The options will expire, unless previously exercised, no later than ten years from the grant date.

The following table summarizes option activity of the company:



	Total Number of Shares (In Thousands)		Weighted Average Exercise Price		Aggregate Intrinsic Value (In Thousands)
Outstanding at January 1, 2015	8,590		$	3.25	$	820
Granted	3,682		1.73		89
Exercised	(1	)	0.85		1
Cancelled	(860	)	2.48		16
Outstanding at June 30, 2015	11,411		$	2.82	$	892
Options exercisable at June 30, 2015	6,169		$	3.41	$	749

The aggregate intrinsic values of outstanding and exercisable options at June 30, 2015 were calculated based on the closing price of the company’s common stock as reported on The NASDAQ Capital Market on June 30, 2015 of $1.70 per share. The aggregate intrinsic value equals the positive difference between the closing fair market value of the company’s common stock and the exercise price of the underlying options.

Note 10. Other Income (Expense)

Other income (expense) is summarized as follows (in thousands):



	Three Months Ended June 30,					Six Months Ended June 30,

Total other income (expense)	$	83	$	(491	)	$	(238	)	$	(656	)

11. Net Loss Per Share

The company accounts for and discloses net loss per common share in accordance with FASB ASC Topic 260 “ Earnings per Share.” Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding. Diluted net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares that would have been outstanding during the period assuming the issuance of common shares for all potential dilutive common shares outstanding. Potential common shares consist of shares issuable upon the exercise of stock options and warrants.

The following table sets forth the potentially dilutive common shares excluded from the calculation of net loss per common share because their inclusion would be anti-dilutive (in thousands):



	Three and Six Months Ended June 30,
	2015	2014
Warrants to purchase common stock	22,308	9,560
Options to purchase common stock	11,411	9,848
Total	33,719	19,408

12. License Agreements

As part of its business, the company enters into licensing agreements with third parties that often require milestone and royalty payments based on the progress of the licensed assets through development and commercial stages. Milestone payments may be required, for example, upon approval of the product for marketing by a regulatory agency, and the company may be required to make royalty payments based upon a percentage of net sales of the product. The expenditures required under these arrangements in any period may be material and are likely to fluctuate from period to period.

These arrangements sometimes permit the company to unilaterally terminate development of the product and thereby avoid future contingent payments; however, the company is unlikely to cease development if the compound successfully achieves clinical testing objectives.

In conjunction with the acquisition of NeuVax ^TM , the company acquired rights and assumed obligations under a license agreement among Apthera and The University of Texas M. D. Anderson Cancer Center (“MDACC”) and The Henry M. Jackson Foundation for the Advancement of Military Medicine, Inc. (“HJF”) which grants exclusive worldwide rights to a U.S. patent covering the nelipepimut-S peptide and several U.S. and foreign patents and patent applications covering methods of using the peptide as a vaccine. Under the terms of this license, we are required to pay an annual maintenance fee of $200,000 , a milestone payment of $200,000 upon commencing the Phase 3 PRESENT trial of NeuVax and other clinical milestone payments, as well as royalty payments based on sales of NeuVax or other therapeutic products developed from the licensed technologies.

Effective December 3, 2012, we entered into a license and supply agreement with ABIC Marketing Limited, a subsidiary of Teva Pharmaceuticals (“ABIC”), under which we granted ABIC exclusive rights to seek marketing approval in Israel for our NeuVax product candidate for intradermal injection for the treatment of breast cancer following its approval by the FDA or the European Medicines Agency, and to market, sell and distribute NeuVax in Israel assuming such approval is obtained. ABIC’s rights also include a right of first refusal in Israel for all future indications for which NeuVax may be approved. Under the license and supply agreement, ABIC will assume responsibility for regulatory registration of NeuVax in Israel, provide financial support for local development, and commercialize the product in the region in exchange for making royalty payments to us based on future sales of NeuVax. ABIC also agrees in the license and supply agreement to purchase from us all supplies of NeuVax at a price determined according to a specified formula.

On March 18, 2013, we acquired Abstral ^® (fentanyl) Sublingual Tablets, a transmucosal immediate-release fentanyl (TIRF) product, for sale and distribution in the United States from Orexo AB (ORX.ST), an emerging specialty pharmaceutical company based in Sweden, and exclusively licensed certain intellectual property from Orexo to use, distribute, market, sell, offer for sale Abstral solely in the United States and to non-exclusively manufacture Abstral for use, distribute, market, sell, offer for sale and import Abstral solely in the United States. Abstral has been approved by the U.S. Food and Drug Administration (FDA).

Under our agreement with Orexo, we assumed responsibility for the U.S. commercialization of Abstral and for all regulatory and reporting matters in the U.S. We also agreed to establish and maintain through 2015 (marketing period) a specified minimum commercial field force to market, sell and distribute Abstral and to use commercially reasonable efforts to reach the specified sales milestones. Orexo is entitled to reacquire the U.S. rights to Abstral from us for no consideration if we breach our obligations to establish and maintain the requisite sales force throughout the marketing period. We expect to maintain our sales efforts beyond this date. We officially launched U.S. commercial sales of Abstral in October 2013.

In exchange for the U.S. rights to Abstral, (1) we paid Orexo $10 million upfront, and a $5 million milestone payment in cash in October 2013 upon the approval by the FDA of a specified U.S. manufacturer of Abstral; and (2) we agreed to pay to Orexo: (a) three one-time future cash milestone payments based on our net sales of Abstral; and (b) a low double-digit royalty on future net sales. No further milestone or royalty payments will be due after the date on which all claims of the last remaining licensed patents expire (currently 2019 ) or become invalidated by a patent office, court, or other governmental agency of competent jurisdiction in a final and non-appealable judgment. In exchange of license, Galena agreed to pay eight-eight percent of the expenses and costs incurred to prosecute any ANDA action..

On January 12, 2014, we acquired worldwide rights to anagrelide controlled release (CR) formulation, which we renamed GALE-401, through our acquisition of Mills Pharmaceuticals, LLC ("Mills") and Mills became a wholly owned subsidiary. GALE-401 contains the active ingredient anagrelide, an FDA-approved product that has been in use since the late 1990s for the treatment of essential thrombocythemia (ET). Mills holds an exclusive license to develop and commercialize anagrelide CR formulation, pursuant to a license agreement with BioVascular, Inc. Under the terms of the license agreement, Mills has agreed to pay BioVascular, Inc. a mid-to-low single digit royalty on net revenue from the sale of licensed products as well as future cash milestone payments based on the achievement of specified regulatory milestones. Mills is also responsible for patent prosecution and maintenance.

On July 17, 2014, we entered into a definitive license and supply agreement with MonoSol for the U.S. commercial rights to Zuplenz ^® (ondansetron) Oral Soluble Film, an FDA-approved product for the prevention of highly and moderately emetogenic chemotherapy-induced nausea and vomiting (CINV), radiotherapy-induced nausea and vomiting (RINV), and post-operative nausea and vomiting (PONV). In exchange for the U.S. rights to Zuplenz, and in connection with the effectiveness of the license and transfer to us of the New Drug Application (NDA) for Zuplenz, we paid MonoSol a total of $5 million in cash and shares of our common stock in 2014 and $0.5 million in cash in 2015. In addition to these payments, we will pay MonoSol $0.25 million within 30 days after MonoSol’s payment of applicable fees relating to the notice of allowance by the United States Patent and Trademark Office of a U.S. patent with composition claims covering Zuplenz that extend beyond 2028, (ii) future cash milestone payments of up to an aggregate of $16.5 million based on our achievement of specified “net sales” of Zuplenz in amounts ranging from $20 million to $100 million , and (iii) a low double-digit royalty on future “net sales.”

Under the terms of the license agreement, we assumed responsibility for the commercialization of Zuplenz and for all regulatory and reporting matters in the U.S. We also agreed in the license and supply agreement to use our best commercial efforts to begin commercializing Zuplenz in the U.S. in accordance with a joint commercialization plan to be established by the company and MonoSol. We also agreed that, until net sales of Zuplenz exceed a specified minimum amount or a competing product has been approved by the FDA and is placed into the market for sale, we will maintain a specified minimum number of field sales force personnel on specified terms.

Under the license and supply agreement, MonoSol has the exclusive right to supply all of our requirements for Zuplenz, subject to certain conditions.

Overview

Galena Biopharma, Inc. (“we,” “us,” “our,” “Galena” or the “company”) is a biopharmaceutical company focused on developing and commercializing innovative, targeted oncology therapeutics that address major unmet medical needs across the full spectrum of cancer care. Galena’s development portfolio ranges from mid- to late-stage clinical assets, including a robust immunotherapy program led by NeuVax™ (nelipepimut-S) currently in an international, Phase 3 clinical trial. The company’s commercial drugs include Abstral ^® (fentanyl) Sublingual Tablets and Zuplenz ^® (ondansetron) Oral Soluble Film. Collectively, our clinical and commercial strategy focuses on identifying and advancing therapeutic opportunities to improve cancer care, from direct treatment of the disease to the reduction of its debilitating side-effects.

We are seeking to build value for shareholders through pursuit of the following objectives:

•

Develop novel cancer immunotherapies to address unmet medical needs through the use of peptide based vaccines targeting well-established tumor antigens in the adjuvant, minimum residual disease setting, in high risk patients who are more likely to benefit from treatment via immunotherapy. Our immunotherapy programs currently seek to significantly decrease the risk of disease recurrence in breast, gastric, endometrial and ovarian cancers.

•

Expand our development pipeline by enhancing the potential clinical and geographic footprint of our technologies. We can accomplish this through the initiation of additional clinical trials as well as through acquisition of additional development stage products in related oncology indications. We also seek to leverage valuable partnerships and collaborations, as well as investigator-sponsored trial arrangements, to maximize the scope of potential clinical opportunities in a cost effective and efficient manner.

•

Maintain commercial capabilities to sell, market, and distribute oncology related pharmaceutical products in the U.S. through our established commercial infrastructure. This commercial strategy creates the opportunity to generate accretive cash flows to support our development programs, and also provides future leverage to support the potential commercialization of our clinical stage technologies in one of the world's largest economic markets.

The chart below summarizes the current status of our pipeline:

Novel Cancer Immunotherapies

Our therapies utilize immunologically active peptides combined with the immune adjuvant, recombinant human granulocyte macrophage-colony stimulating factor (rhGM-CSF), and work by harnessing the patient’s own immune system to target, seek out and attack any residual cancer cells. Using peptide immunogens has many potential clinical advantages, including a favorable safety profile, since these drugs may lack the toxicities typical of most cancer therapies. They also have the potential to evoke long-lasting protection through activation of the immune system through a convenient, and a patient friendly intradermal mode of delivery. We are currently engaged in multiple clinical trials with NeuVax™ (nelipepimut-S) and GALE-301, or Folate Binding Protein (FBP), targeting the prevention of recurrence in breast, gastric, ovarian and endometrial cancers.

NeuVax™ (nelipepimut-S)

Breast Cancer : According to the National Cancer Institute, over 230,000 women in the U.S. are diagnosed with breast cancer annually. While improved diagnostics and targeted therapies have decreased breast cancer mortality in the U.S., metastatic breast cancer remains incurable. Approximately 75% of breast cancer patients have tissue test positive for some increased amount of the HER2 receptor, which is associated with disease progression and decreased survival. Only approximately 20% to 30% of all breast cancer patients - those with HER2 immunohistochemistry (IHC) 3+ disease, or IHC 2+ and fluorescence in situ hybridization (FISH) positive - have an approved treatment option available. This leaves the majority of breast cancer patients with low-to-intermediate HER2 IHC 1+/2+ ineligible for targeted therapy and without an effective treatment option to prevent cancer recurrence.

Gastric Cancer : Gastric cancer (also known as stomach cancer) is a disease in which the cells forming the inner lining of the stomach become abnormal and start to divide uncontrollably, forming a cancerous tumor mass. Cancer can develop in any of the five sections of the stomach. Symptoms and outcomes of the disease will vary depending on the location of the cancer. Stomach cancer is one of the leading causes of cancer deaths in several areas of the world, most notably in Asian countries. Annually, almost one million people will be diagnosed worldwide with stomach cancer and over 700,000 will die from the disease. More than 90% of stomach cancers are caused by adenocarcinomas, malignant cancers that originate in glandular tissues. Overexpression of the HER2 receptor occurs in approximately 20% of gastric and gastro-esophageal junction adenocarcinomas, predominantly those of the intestinal type. Overall, only approximately 28% of patients with stomach cancer live at least five years following diagnosis and new adjuvant treatments are needed to prevent disease recurrence.

We currently have a number of ongoing or planned clinical trials designed to expand the clinical and geographic footprint of NeuVax:

•


•	Phase 2b Ongoing: A randomized, multicenter, investigator-sponsored, 300 patient Phase 2b clinical trial is enrolling HER2 1+/2+ node-positive and high-risk node-negative HLA A2/A3/A24/A26 breast cancer patients to study NeuVax in combination with trastuzumab (Herceptin ^® ; Genentech/Roche) in the adjuvant setting. This trial is partially funded by Genentech/Roche.

•


•	Phase 2 Planned: In January 2014, we partnered with Dr. Reddy’s Laboratories, Ltd. in India for the commercialization of NeuVax in that region. Dr. Reddy’s is responsible for managing a Phase 2 gastric cancer trial of NeuVax in India in patients that express any level of HER2 (1+, 2+, and 3+). The trial is expected to initiate in 2016.

GALE-301 (folate binding protein or FBP)

Ovarian and Endometrial Cancer : Ovarian cancer occurs in more than 22,000 patients per year in the U.S. and is the most lethal gynecologic cancer. Despite the incidence of ovarian cancer being only approximately 10% of that of breast cancer, the number of patients who die from ovarian cancer is nearly 50% that of breast cancer. Due to the lack of specific symptoms, the majority of ovarian cancer patients are diagnosed at later stages of the disease. For their treatment, these patients typically have their tumors surgically debulked to minimal residual disease, and then are treated with platinum- and/or taxane-based chemotherapy. While most patients respond to this treatment regimen and become clinically free-of-disease, the majority of these patients will relapse, and once the disease recurs, the treatment options and successes drop dramatically. Endometrial cancer is the most common gynecologic cancer and occurs in more than 46,000 women with more than 8,000 deaths in the U.S. annually. There are two basic types of endometrial cancer: endometrioid and papillary serous. The latter has a much more aggressive clinical course and the majority of these patients will die of this form of the disease.

Hematology

GALE-401 (anagrelide controlled release (CR))

Myeloproliferative neoplasms : MPNs are a closely related group of hematological malignancies in which the bone marrow cells that produce the body's blood cells develop and function abnormally. The main myeloproliferative neoplasms are Polycythemia Vera (PV), Essential Thrombocythemia (ET), Primary Myelofibrosis (PMF), and Chronic Myelogenous Leukemia (CML), all of which are associated with high platelet counts. The MPNs are progressive blood cancers that can strike anyone at any age, and for which there is no known cure.

Commercial Capabilities

Though we primarily develop innovative, targeted oncology therapeutics that address major unmet medical needs across the full spectrum of cancer care, we have established a commercial operation to market and sale acquired commercial products.

Abstral ^® (fentanyl) Sublingual Tablets

Zuplenz ^® (ondansetron) Oral Soluble Film

Recent Operational Developments (in reverse chronological order)

Launched Zuplenz - We officially launched Zuplenz ^® (ondansetron) oral soluble film.

On July 29/30, 2015, we announced the official launch of Zuplenz (ondansetron) Oral Soluble Film, in the United States. Zuplenz is now available nationwide and is supplied in both 4 mg and 8 mg ondansetron doses. Zuplenz is clinically bioequivalent to ondansetron orally disintegrating tablets (ODT) with a safety profile equivalent to ondansetron. The novel, PharmFilm ^® , oral soluble film technology utilized by Zuplenz provides for convenient delivery and several key patient benefits including:


•	Rapidly dissolves in the mouth in about 10 seconds.


•	Eliminates the burden of swallowing pills during emesis.


•	Does not require water to administer, making it ideal in cases of oral irritation.


•	Pleasant peppermint flavor with no gritty aftertaste.


•	Nonsedating.

Zuplenz is approved in adult patients for the prevention of highly and moderately emetogenic chemotherapy-induced nausea and vomiting (CINV), radiotherapy-induced nausea and vomiting (RINV), and post-operative nausea and vomiting (PONV). Zuplenz is also approved for moderately emetogenic CINV in pediatric patients four years and older.

The active pharmaceutical ingredient in Zuplenz, ondansetron, is used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, and surgery. The National Comprehensive Cancer Network (NCCN) 2014 guidelines recommend the use of ondansetron in patients with highly and moderately emetogenic cancer chemotherapy-induced, and radiotherapy-induced nausea and vomiting. Ondansetron belongs to a class of medications called serotonin 5-HT3 receptor antagonists and works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting. The product was licensed from MonoSol Rx, LLC, the developer of the oral soluble film technology, PharmFilm®, and manufacturer of the product.

GALE 401 Phase 2 clinical trial data presented - We presented data from our Phase 2 clinical trial of GALE-401 at the European Hematology Association 20 ^th Congress in Vienna, Austria.

On June 15, 2015, we announced our poster presentation entitled "Phase 2 Study of a Novel Controlled-Release Formulation of Anagrelide (GALE-401) in Subjects with Myeloproliferative Neoplasm (MPN)-Related Thrombocytosis," which was presented on June 13, 2015. The Phase 2 study demonstrated that GALE-401 was well tolerated with primarily Grade 1 and 2 toxicities in 16 of the 18 subjects enrolled. The efficacy shown in the trial compares favorably to historical anagrelide immediate release (IR) response rates with the following platelet response: overall response rate (ORR) of 78% (14/18); complete response (CR) of 39% (7/18); partial response (PR) of 39% (7/18). The median time to response was 5 weeks (range, 3-10), and the median duration of response has not yet been reached. Based on the data, the investigators concluded that GALE-401 remains a viable potential treatment option for MPNs, and a randomized trial comparing GALE-401 versus anagrelide IR is warranted. Final data from the GALE-401 Phase 2 trial is expected to be presented later this year.

Published Abstracts related to GALE-301 and Leica Biosystem’s Companion Diagnostic - We presented two abstract publications at the American Society of Clinical Oncology (ASCO) 2015 Annual Meeting.

On May 27, 2015, we announced two abstract publications at the ASCO 2015 Annual Meeting related to our cancer immunotherapy programs, one related to GALE-301 and one related to the companion diagnostic in our NeuVax Phase 3 PRESENT trial.

We presented data related to GALE-301 in abstract #e14031, entitled, "Preliminary Results of the Phase I/IIa Dose Finding Trial of a Folate Binding Protein Vaccine (E39+GM-CSF) in Ovarian and Endometrial Cancer Patients to Prevent Recurrence." This data showed that GALE-301 is well tolerated and elicits a strong and dose-dependent in vivo immune response. The trial is designed as a safety and dose optimization trial and is not powered for a disease free survival efficacy endpoint. However, early efficacy results from the trial are promising in the 1000 mcg dose cohort. Of the 51 patients enrolled in the trial, 29 were in the vaccinated group (15 patients at 1000 mcg vs. 14 patients at < 1000 mcg) and 22 were in the control group. With 9.8 months median follow-up, the 1000 mcg vaccine dose group had only one clinical recurrence vs 11 in the control group (6.7% VG vs. 50% CG, p = 0.01). Combining all dose groups, the complete response (CR) rate was 38% in the

vaccine group vs. 50% in the control group (p = 0.41). Currently, the estimate for disease free survival at two years is 85.7% (1000 mcg dose group) vs. 19.2% for the control group (p = 0.09), for a 78% reduction in relative risk of recurrence.

We presented data related to our NeuVax Phase 3 PRESENT trial companion diagnostic in abstract #e11609, entitled, "Analytical Validation of BOND Oracle HER2 IHC System for Identifying Low to Intermediate HER2 Expressing Breast Cancer in NeuVax PRESENT Phase 3 Clinical Trial." This data demonstrated a direct correlation between cell line receptor load, quantitative measure of HER2 protein, and IHC score. The ability to discriminate HER2 protein expression at the low and intermediate levels in breast cancer tumors will identify patients for new treatments in development such as NeuVax. Specifically, the validation of the Bond Oracle HER2 IHC System to distinguish lower levels of HER2+ expressions supports its use as a companion diagnostic.

NeuVax Phase 3 PRESENT Over-Enrollment Completed - We announced the completion of enrollment in our NeuVax Phase 3 PRESENT clinical trial.

On April 14, 2015 we announced the completion of enrollment in the NeuVax™ (nelipepimut-S) Phase 3 PRESENT ( P revention of R ecurrence in E arly- S tage, Node-Positive Breast Cancer with Low to Intermediate HER2 E xpression with NeuVax T reatment) clinical trial. NeuVax is a first-in-class, HER2-directed cancer immunotherapy under evaluation to prevent breast cancer recurrence after standard of care treatment in the adjuvant setting. As anticipated, we over-enrolled the trial by 7.7% with a total of 758 patients now in the intent-to-treat (ITT) population. The protocol for the PRESENT trial, being conducted under an FDA approved Special Protocol Assessment (SPA), called for 700 patients; and, the Company expects this higher number of ITT patients will increase the confidence in both the timing and quality of the statistics and the final outcome of the trial. The primary endpoint is currently expected to be reached in 2018, after the last patient dosed reaches her 36th month of treatment, or a total of 141 events (recurrence or death) occur, whichever comes later.

Expanded Patient Population in NeuVax Combination Trial - We announced the expansion of the patient population in the NeuVax and trastuzumab combination trial in HER2 1+/2+ patients to include HLA A24+ and HLA-A26+ patients.

On March 26, 2015, we announce that human leukocyte antigen (HLA) - A24+ or HLA-A26+ women are now eligible for enrollment into the ongoing Phase 2b clinical trial with NeuVax™ (nelipepimut-S) in combination with trastuzumab (Herceptin ^® ; Genentech/Roche). The trial evaluates node positive and triple negative, node negative breast cancer patients with immunohistochemistry (IHC) HER2 1+/2+ expressing tumors who are disease-free after standard of care therapy.

Enrolled 700 ^th Patient in NeuVax Phase 3 PRESENT Clinical Trial - We announced enrollment of the 700 ^th patient in our Phase 3 PRESENT clinical trial.

On February 9, 2015, we announced the enrollment of the 700 ^th patient in the NeuVax™ (nelipepimut-S) Phase 3 PRESENT ( P revention of R ecurrence in E arly- S tage, Node-Positive Breast Cancer with Low to Intermediate HER2 E xpression with NeuVax T reatment) clinical trial. Seven hundred is the patient enrollment target as defined by the PRESENT Phase 3 clinical trial protocol.

Results of Operations for the Three and Six Months Ended June 30, 2015 and 2014

For the three months ended June 30, 2015 , our net loss was approximately $15.7 million compared with a net loss of $19.9 million for the three months ended June 30, 2014 . The net loss decreased by $4.3 million , or approximately 21% , primarily attributable to a $4.6 million dollar reduction in our operating loss, discussed in more detail below, partially offset by a $0.9 million increase in our non-cash loss on our warrant liability.

For the six months ended June 30, 2015 , our net loss was approximately $26.2 million compared with a net loss of $22.5 million for the six months ended June 30, 2014 . The net loss increased by $3.7 million , or approximately 17% , primarily attributable to a $6.4 million non-cash gain on our warrant liability for the six months ended June 30, 2014 compared to a $3.1 million non-cash loss on our warrant liability for the six months ended June 30, 2015 , partially offset by a $5.3 million reduction in our operating loss, discussed in more detail below.

Abstral is our first commercial product and revenue was recorded for the first time during the year ended December 31, 2013. We acquired our second commercial product, Zuplenz, in the third quarter of 2014 and launched the product in July 2015. There was no gross or net revenue from the sale of Zuplenz in any of the periods presented. For these reasons, we expect our future results of operations may differ materially from our historical results. We expect to continue to incur significant costs and expenses in connection with our commercial operations in the U.S. We must achieve higher net sales before realizing a profit from the sale and distribution of our commercial products. Further analysis of the changes and trends in our operating results are discussed below.

Net Revenue

The company recognizes revenue from the sale of Abstral to wholesale pharmaceutical distributors and retail pharmacies, net of product-related discounts, allowances, an estimate of product returns, rebates, chargebacks, and patient assistance benefits, as applicable.

Gross revenue for the three and six months ended June 30, 2015 and 2014 was comprised of gross to net deductions and net revenue as follows:



	Net revenue		Gross to net deductions

Net revenue for the three months ended June 30, 2015 increased 45% compared to the three months ended June 30, 2014 . The increase was a result of a 38% improvement in the gross to net deductions and a 19% increase in gross revenue. In March of 2014 we launched the Galena Patient Services (GPS) program, a full service support program designed to navigate patient access to Abstral that is coordinated through a third party vendor. Along with the launch of GPS, we also made changes to our patient assistance program (PAP) to reduce the use of free product vouchers and rely more heavily upon an expedited prior authorization process. The success of the GPS program has resulted in a significant improvement in our gross to net deductions as a percent of gross revenue.

Overall prescription demand increased 23% for the three months ended June 30, 2015 compared to three months ended June 30, 2014 . More importantly, non-voucher prescriptions increased 77% for the three months ended June 30, 2015 compared to the three months ended June 30, 2014 , as a direct result of the successful implementation of our GPS program and the changes to our PAP program resulting in a reduction in the percentage of our prescriptions being filled with vouchers.

Net revenue for the six months ended June 30, 2015 increased 36% compared to the six months ended June 30, 2014 . The increase was a result of a 38% improvement in the gross to net deductions and gross revenues increased nominally. In March of 2014 we launched the Galena Patient Services (GPS) program, a full service support program designed to navigate patient access to Abstral that is coordinated through a third party vendor. Along with the launch of GPS, we also made changes to our patient assistance program to reduce the use of free product vouchers and rely more heavily upon an expedited prior authorization process. The success of the GPS program has resulted in a significant improvement in our gross to net deductions as a percent of gross revenue.

Overall prescription demand increased 16% for the six months ended June 30, 2015 compared to six months ended June 30, 2014 . More importantly, non-voucher prescriptions increased 92% for the six months ended June 30, 2015 compared to the six months ended June 30, 2014 , as a direct result of the successful implementation of our GPS program and the changes to our PAP program resulting in a reduction in the percentage of our prescriptions being filled with vouchers. Our current expectations for 2015 net revenue from the sale of our commercial products is approximately $15 million, but there is no assurance we will achieve our expectations. We acquired our second commercial product, Zuplenz, in the third quarter of 2014 and launched the product in July 2015. No revenue has been recorded from the sale of Zuplenz in the periods presented.

Cost of Revenue and Amortization of Certain Acquired Intangible Assets

Cost of revenue and amortization of certain acquired intangible assets for the three months ended June 30, 2015 and 2014 , respectively, were as follows (dollars in thousands):



	Three Months Ended June 30,
	2015		% of net revenue		2014		% of net revenue
Cost of revenue (excluding amortization of certain acquired intangible assets:
Abstral royalties	$	406	12	%	$	281	12	%
Direct product costs and related overhead	19		1	%	21		1	%
Other cost of revenue	43		1	%	45		2	%
Total cost of revenue	$	468	14	%	$	347	15	%
Amortization of certain acquired intangible assets	$	442	13	%	$	98	4	%

Cost of revenue, which excludes the amortization of certain acquired intangible assets, was $0.5 million and $0.3 million for the three months ended June 30, 2015 and 2014, respectively. Variable cost of revenue includes the royalty due to Orexo and product costs. Product related overhead and other cost of revenue are fixed in nature, and will decrease or increase as a percentage of net revenue as net revenue increases or decreases, respectively. Cost of revenue improved slightly as a percent of net revenue which is attributable to the 45% increase in net revenue for the three months ended June 30, 2015 compared to three months ended June 30, 2014 .

Amortization of certain acquired intangible assets was $0.4 million and $0.1 million for the three months ended June 30, 2015 and 2014, respectively. Amortization of certain acquired intangible assets is a non-cash variable cost based on net revenue during the period.

Cost of revenue and amortization of certain acquired intangible assets for the six months ended June 30, 2015 and 2014 , respectively, were as follows (dollars in thousands):



	Six Months Ended June 30,
	2015		% of net revenue		2014		% of net revenue
Cost of revenue (excluding amortization of certain acquired intangible assets:
Abstral royalties	$	736	12	%	$	540	12	%
Direct product costs and related overhead	38		1	%	50		1	%
Other cost of revenue	87		1	%	88		2	%
Total cost of revenue	$	861	14	%	$	678	15	%
Amortization of certain acquired intangible assets	$	588	10	%	$	189	4	%

Cost of revenue, which excludes the amortization of certain acquired intangible assets, was $0.9 million and $0.7 million for the six months ended June 30, 2015 and 2014, respectively. Variable cost of revenue includes the royalty due to Orexo and product costs. Product related overhead and other cost of revenue are fixed in nature, and will decrease or increase as a percentage of net revenue as net revenue increases or decreases, respectively. Cost of revenue improved slightly as a percent of net revenue, which is attributable to the 36% increase in net revenue for the six months ended June 30, 2015 compared to six months ended June 30, 2014 .

Amortization of certain acquired intangible assets was $0.6 million and $0.2 million for the six months ended June 30, 2015 and 2014, respectively. Amortization of certain acquired intangible assets is a non-cash variable cost based on net revenue during the period.

Research and Development Expense

Research and development expense consists primarily of clinical trial expenses, compensation-related costs for our employees dedicated to research and development activities, compensation paid to our Scientific Advisory Board (“SAB”) members, and licensing fees and patent prosecution costs. Research and development expense for the three and six months ended June 30, 2015 and 2014 , respectively, was as follows (dollars in thousands):



	Three Months Ended June 30,						Six Months Ended June 30,
	2015		2014		% Change		2015		2014		% Change
Research and development expense	$	7,290	$	8,069	(10	)%	$	13,200	$	14,839	(11	)%

The decreases of 10% and 11% for the three and six months ended June 30, 2015 compared to the three and months ended June 30, 2014 in research and development expense was primarily related to the completion of our enrollment efforts for the Phase 3 PRESENT clinical trial. We expect research and development expense related to our PRESENT trial to decrease throughout 2015 as we transition to the monitoring and follow-up phase. The expected decrease in costs could be partially offset by the increase in research and development expense related to enrollment efforts in our NeuVax combination clinical trials, ongoing trial costs related to our GALE-301 Phase 2 clinical trial, and completion of our Phase 2 clinical trial of the GALE-401 program.

Selling, General and Administrative Expense

Selling, general and administrative expense includes compensation-related costs for our employees dedicated to sales and marketing, general and administrative activities, legal fees, audit and tax fees, consultants and professional services, and general corporate expenses. Selling, general and administrative expense for the three and six months ended June 30, 2015 and 2014 , respectively, was as follows (dollars in thousands):



	Three Months Ended June 30,						Six Months Ended June 30,
	2015		2014		% Change		2015		2014		% Change
Selling, general and administrative expense	$	6,451	$	9,600	(33	)%	$	13,878	$	16,430	(16	)%

The 33% and 16% decreases in selling, general, and administrative expense for the three and six months ended June 30, 2015 compared to the three and six months ended June 30, 2014 , respectively, was driven by the $3 million incurred in legal expenses during the three months ended related to the ongoing litigation and proceedings described in Part II, Item 1 of this report. During the third quarter of 2014 we exceeded the retention (deductible) under our insurance policy and have been realizing significant insurance recoveries against the fees associated with the litigation and proceedings referenced above. This decrease was partially offset by the ramp up of our commercial operations leading into the launch of Zuplenz, the expansion of our management team and infrastructure needed to support the expanded commercial operations and development pipeline.

Non-Operating Income

Non-operating income for the three and six months ended June 30, 2015 and 2014 , respectively, was as follows (dollars in thousands):



	Three Months Ended June 30,								Six Months Ended June 30,
	2015			2014			% Change		2015			2014			% Change
Change in fair value of warrants potentially settleable in cash	$	(4,267	)	$	(3,353	)	27	%	$	(3,115	)	$	6,439		(148	)%
Interest income (expense), net	(207		)	(314		)	(34	)%	(449		)	(628		)	(29	)%
Other income (expense)	83			(491		)	(117	)%	(238		)	(656		)	(64	)%
Total non-operating income (expense), net	$	(4,391	)	$	(4,158	)	6	%	$	(3,802	)	$	5,155		(174	)%

The decrease in our non-operating income (increase in our net non-operating expense) during the three and six months ended June 30, 2015 compared to the three and six months ended June 30, 2014 was primarily due to a increase in the change in fair value of warrants accounted for as liabilities. This increase in the estimated fair value of our warrant liabilities was primarily due to the increase in our common stock price, which is one of the most impactful inputs into the pricing model we use to estimate the fair value of our warrant liabilities.

Income Taxes

For the three and six months ended June 30, 2015 and 2014, there was no income tax benefit or expense recognized.

Liquidity and Capital Resources

We had cash and cash equivalents of approximately $45.3 million as of June 30, 2015 , compared with $23.7 million as of December 31, 2014.

The increase of approximately $21.6 million in our cash and cash equivalents from December 31, 2014 to June 30, 2015 was attributable primarily to $47.4 million in net proceeds from issuance of common stock and warrants to purchase common stock, partially offset by $23.4 million used in operating activities, $1.9 million in payments on long-term debt, and $0.5 million for a milestone related to our acquisition of U.S. rights to Zuplenz.

On March 18, 2015, we announced the closing of our underwritten public offering of 24,358,974 shares of common stock and 12,179,487 warrants to purchase our common stock at an exercise price of $2.08. The underwriters also exercised their over-allotment option to purchase warrant to purchase an aggregate of 1,826,923 shares of our common stock. On April 10, 2015 the underwriters exercised their option to purchase an additional 3,653,846 shares of common stock for additional net proceeds of $5.4 million. The total net proceeds to us were approximately $40.8 million.

We expect to continue to incur operating losses as we continue to commercialize Abstral, launch commercialization of Zuplenz in the U.S. and advance our product candidates through the drug development and regulatory process. We will need to generate significant revenue to achieve profitability and may never do so. In the absence of revenue from the commercialization of Abstral, Zuplenz or our product candidates, our potential sources of operational funding are proceeds from the sale of equity and funded research and development payments and payments received under partnership and collaborative agreements.

We believe that our existing cash and cash equivalents, along with revenue from our commercial operations, should be sufficient to fund our operations for at least one year. This projection is based on our current planned operations and revenue expectations and is subject to changes in our plans and uncertainties inherent in our business, and we may need to seek to replenish our existing cash and cash equivalents sooner than we project. There is no guarantee that we will generate sufficient revenue from the sale of Abstral and Zuplenz to become profitable or that any debt, additional equity or other funding will be available to us on acceptable terms, or at all. If we fail to generate adequate revenue or obtain additional funding when needed, we would be forced to scale back, or terminate our operations or to seek to merge with or to be acquired by another company.

Cash Flows

The following table summarizes our cash flows from operating, investing, and financing activities for the six months ended June 30, 2015 and June 30, 2014 ($ in thousands):



	Six Months Ended June 30,
	2015			2014
Total cash provided by (used in):
Operating activities	$	(23,415	)	$	(21,020	)
Investing activities	(569		)	(2,344		)
Finance activities	45,613			14,739
Increase (decrease) in cash and cash equivalents	$	21,629		$	(8,625	)

Net Cash Flow from Operating Activities

Net cash used in operating activities was approximately $23.4 million for the six months ended June 30, 2015 , compared with $21.0 million for the six months ended June 30, 2014 . Despite a $5 million reduction in the operating loss for the six months ended June 30, 2015 compared with the six months ended June 30, 2014 , net cash used in operating activities increased due to the paying down of accrued expenses and other current liabilities during the six months ended June 30, 2015 .

Net Cash Flow from Investing Activities

Net cash used in investing activities was $0.6 million for the six months ended June 30, 2015 , compared with $2.3 million for the six months ended June 30, 2014 . The decrease was due to the $2.1 million initial payment for GALE-401 rights during the six months ended June 30, 2014 compared to the $0.5 million milestone payment for U.S. rights to Zuplenz during the six months ended June 30, 2015 .

Net Cash Flow from Financing Activities

Net cash provided by financing activities was $45.6 million for the six months ended June 30, 2015 , compared with $14.7 million for the six months ended June 30, 2014 . The increase was primarily attributable to $42.2 million in net proceeds from the issuance of common stock and warrants to purchase common stock during the six months ended June 30, 2015 compared to net proceeds of common stock warrant exercises of $10.6 million and net proceeds of common stock option exercises of $4.1 million during the six months ended June 30, 2014 .

Off-Balance Sheet Arrangements

We have not entered into any off-balance sheet financing arrangements other than operating leases.

Critical Accounting Policies and Estimates

In our Annual Report on Form 10-K for the year ended December 31, 2014, we disclosed our critical accounting policies and estimates upon which our financial statements are derived. There have been no changes to these policies since December 31, 2014 that are not included in Note 1 of the accompanying condensed consolidated financial statements for the three and six months ended June 30, 2015. Readers are encouraged to read our Annual Report on Form 10-K in conjunction with this report.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

The primary objective of our investment activities is to preserve capital. We do not utilize hedging contracts or similar instruments.

We are exposed to certain market risks relating primarily to interest rate risk on our cash and cash equivalents and risks relating to the financial viability of the institutions which hold our capital and through which we have invested our funds. We manage the latter risks by investing primarily in money market mutual funds.

In addition, we are exposed to foreign currency exchange rate fluctuations relating to payments we make to certain vendors and suppliers and license partners using foreign currencies. We do not hedge against foreign currency risks. Consequently, changes in exchange rates could adversely affect our operating results and stock price. Such losses have not been significant to date.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

As of the end of the period covered by this quarterly report on Form 10-Q, our principal executive officer and our principal accounting officer (the “Certifying Officers”), evaluated the effectiveness of our disclosure controls and procedures. Disclosure controls and procedures are controls and procedures designed to reasonably assure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934 (the “Exchange Act”), such as this quarterly report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms. Disclosure controls and procedures are also designed to reasonably assure that such information is accumulated and communicated to our management, including the Certifying Officers, as appropriate to allow timely decisions regarding required disclosure. Based on these evaluations, the Certifying Officers have concluded, that, as of the end of the period covered by this quarterly report on Form 10-Q:


(a)	our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act was recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms; and


(b)	our disclosure controls and procedures were effective to provide reasonable assurance that material information required to be disclosed by us in the reports we file or submit under the Exchange Act was accumulated and communicated to our management, including the Certifying Officers, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during the three and six months ended June 30, 2015 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1A. RISK FACTORS

In addition the risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2014 and most recent Quarterly Report on Form 10-Q for the three months ended March 31, 2015 filed with the SEC, you should consider the following new or updated risk factors:

Risks Related to Our Business

We are subject to competition and may not be able to compete successfully.

The biotechnology industry, including the cancer immunotherapy market, is intensely competitive and involves a high degree of risk. We compete with other companies that have far greater experience and financial, research and technical resources than us. Potential competitors in the U.S. and worldwide are numerous and include pharmaceutical and biotechnology companies, educational institutions and research foundations, many of which have substantially greater capital resources, marketing experience, research and development staffs and facilities than us. Some of our competitors may develop and commercialize products that compete directly with those incorporating our technology, introduce products to market earlier than our products or on a more cost effective basis. In addition, our technology may be subject to competition from other technology or methods developed using techniques other than those developed by traditional biotechnology methods. Our competitors compete with us in recruiting and retaining qualified scientific and management personnel as well as in acquiring technologies complementary to our technology. Our collaborators or we will face competition with respect to product efficacy and safety, ease of use and adaptability to various modes of administration, acceptance by physicians, the timing and scope of regulatory approvals, availability of resources, reimbursement coverage, price and patent position, including potentially dominant patent positions of others. An inability to successfully complete our product development could lead to us having limited prospects for establishing market share or generating revenue from our technology.

For patients with early stage breast cancer, adjuvant therapy is often given to prevent recurrence and increase the chance of long-term disease free survival. Adjuvant therapy for breast cancer can include chemotherapy, hormonal therapy, radiation therapy, or combinations thereof. In addition, the HER2 targeted drug trastuzumab (Herceptin ) may be given to patients with tumors with high expression of HER2 (IHC 3+), in the adjuvant setting which may be useful in treating breast cancer.

There are a number of cancer vaccines in development for breast cancer, including but not limited to Lapuleucel-T (Dendreon), and AE-37 (Antigen Express). While these development candidates are aimed at a number of different targets, and AE-37 has published data in the HER2 breast cancer patient population, there is no guarantee that any of the these compounds will not in the future be indicated for treatment of low to intermediate HER2 breast cancer patients and become directly competitive with NeuVax.

We may be unable to achieve profitability with our commercial operations in a timely manner, and may have to make changes to our commercial strategy to maximize the value of our commercial assets to our shareholders.

We launched Abstral in the fourth quarter of 2013, and launched Zuplenz on July 29, 2015. As of June 30, 2015, Abstral has not achieved profitability as a product line, and there is no assurance that it will achieve profitability within the period of time outlined by management in setting our commercial strategy. Also, there is no assurance that we will be successful launching Zuplenz, or that Zuplenz will reach profitability as a product line in timely manner, if ever.

Management may determine that a change to our commercial strategy is necessary to address the lack of profitability of the commercial products. Such potential strategic changes include, but are not limited to, increased investment in our commercial operations, significant expansion or reduction to our sale force, acquisition of additional commercial products, or partial or full divesture of our commercial products and operations. Any such significant change to our commercial strategy could materially affect the amounts of revenue we generate in future periods, the extent and timing of future costs incurred, and could result in changes to our financial results that are materially different than those realized historically.

Risks Related to Our Intellectual Property

We may not be able to obtain and enforce patent rights or other intellectual property rights that cover our commercial product or product candidates and that are of sufficient breadth to prevent third parties from competing against us.

Our success with respect to our commercial product and product candidates will depend in part on our ability to obtain and maintain patent protection in the U.S. and abroad, to preserve our trade secrets, and to prevent third parties from infringing upon our proprietary rights. Our patents and patent applications, however, may not be sufficient to provide protection for Abstral, NeuVax, or our other products and product candidates against commercial competition.

The active peptide found in NeuVax, the E75 peptide, has been known and studied for many years. We have one issued U.S. patent, US 6,514,942, covering the composition of matter of the E75 peptide, which expired in March 2015, prior to any potential commercialization of NeuVax. We do not have and will not be able to obtain any composition of matter patent protection for E75, the active peptide in NeuVax outside the U.S. We also have a license from The Henry M. Jackson Foundation to issued U.S. European, Japanese and Australian method of use patents, which expire in 2028, that are directed to a method of inducing immunity against breast cancer recurrence by administering a composition comprising the E75 peptide to patients who have both an immunohistochemistry (IHC) rating of 1+ or 2+ for HER2/neu protein expression as well as a fluorescence in situ hybridization (FISH) rating of less than about 2.0 for HER2/neu gene expression. The license further includes an issued U.S. method of use patent, which expires in 2028, that is directed to a method of inducing immunity against recurrence of any HER2/neu expressing tumors by administering the E75 peptide to patients with tumors having a FISH rating of less than about 2.0 for HER2/neu gene expression. Also included in the license is a method of use patent, which expires in 2026, that is directed to the use of NeuVax in combination with Herceptin ^® to treat any HER2/neu expressing cancer. Thus, our method of use patents may not prevent competitors from seeking to develop and market NeuVax for use in cancer patients who do not meet these criteria. If any such alternative uses were approved, this could lead to off-label use and price erosion for our NeuVax product. We may seek FDA approval for use of NeuVax to treat cancer patients who fall outside the claimed IHC and FISH ranges and for other cancers as well. Although we are pursuing additional patent protection for NeuVax through pending patent applications, we may not be able to obtain additional patent protection that would provide us with a significant commercial advantage.

Anagrelide hydrochloride, the sole active pharmaceutical ingredient, or “API,” in GALE-401, has been approved for many years and, thus, it is not possible to obtain composition of matter patents that cover anagrelide hydrochloride. As a result, competitors who obtain the requisite regulatory approval can offer products with the same API as GALE-401, so long as the competitors do not infringe any formulation patents that we may have or may obtain or license, if any. The only patent protection that we have or are likely to obtain covering GALE-401 are patents relating to specific formulations, methods using these formulations, and methods of manufacturing and packaging. We have an issued U.S. Patent, which expires in 2020, covering methods of using anagrelide to reduce platelet count in patients subject to veno-occlusive events. We have two granted patents in the United Kingdom, an issued U.S. patent and allowed Japanese application, which expire in 2029, covering controlled release formulations of anagrelide and methods of use. We also are prosecuting pending patent applications in other territories including, but not limited to, the U.S. Europe, India and Japan which may not issue prior to any potential commercialization of GALE-401. We may seek FDA approval for use of GALE-401 to treat patients with myeloproliferative neoplasms that include several hermatological disorders. Although we are pursuing additional patent protection for GALE-401 through pending patent applications, we may not be able to obtain additional patent protection that would provide us with a significant commercial advantage.

Orexo AB filed an action in the U.S. District Court for the District of New Jersey on June 30, 2011 asserting infringement by Mylan Pharmaceuticals Inc., of one of our licensed U.S. patents, US 6,761,910, covering Abstral. This patent is directed to pharmaceutical compositions for the treatment of acute disorders by sublingual administration. The claims of the patent cover formulations for other products in addition to Abstral, including Ambien (and generic forms of Ambien, which is the subject of the infringement action). Validity of the patent was challenged as part of the court proceeding, and certain claims in the patent were the subject of a Markman order. Though that action was settled, that Markman order may be used to challenge any infringement claims Orexo would make in the action entitled, Orexo AB vs. Actavis Laboratories FL, Inc. pending in the U.S. District Court for the District of New Jersey. The outcome in the Orexo AB vs. Actavis Laboratories FL, Inc. action could affect our license of the Abstral patents and our ability to market, sell, distribute or manufacture Abstral in the U.S.

The active peptides found in GALE-301 are derived from Folate Binding Protein. One of the active peptides, E39, has been known and studied for many years. The other active peptide(s) in GALE-301 are derivatives of E39. We have a license from The Henry M. Jackson Foundation to issued and granted patents in the U.S., Europe, Canada, and Japan, covering composition of matter for the E39 derivative peptides alone and in combination with E39, as well as the use of these compositions for the treatment of cancer. These patents are expected to expire in 2022, prior to any potential commercialization of GALE-301. We do not have and will not be able to obtain any composition of matter patent protection for the E39 peptide in any territory. The license we have from The Henry M. Jackson Foundation grants us the right to develop and market GALE-301

for any use, including methods of treating cancer. Our patents may not prevent competitors from seeking to develop and market the E39 peptide alone. If any such alternative uses of compositions containing the E39 peptide were approved, this could lead to off-label use and price erosion for GALE-301. We may seek FDA approval for use of GALE-301 to treat cancer patients with ovarian and endometrial cancers and for other cancers as well. Although we are pursuing additional patent protection for GALE-301 through pending patent applications, we may not be able to obtain additional patent protection that would provide us with a significant commercial advantage.

Our ability to obtain, maintain and enforce patents is uncertain and involves complex legal and factual questions. Accordingly, rights under any patents we have or may obtain or license may not provide us with sufficient protection for our commercial product and product candidates to afford a commercial advantage against competitive products or processes, including those from branded and generic pharmaceutical companies. In addition, we cannot guarantee that any patents will issue from any pending or future patent applications owned by or licensed to us. Nor can we guarantee that the claims of these patents will be held valid or enforceable by the courts or the patent office or will provide us with any significant protection against competitive products or otherwise be commercially valuable to us.

Changes in either the patent laws or in the interpretations of patent laws in the U.S. or abroad may diminish the value of our intellectual property. In addition, on September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a number of significant changes to the U.S. patent law. These include provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. The U.S. Patent Office is currently developing regulations and procedures to govern administration of the Leahy-Smith Act, and many substantive changes to patent law associated with the Leahy-Smith Act have not yet become effective. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act, in particular the post grant review processes and first-to-file provision and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement of or defense of our issued patents, all of which could have a material adverse effect on our business and financial condition. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents.

While we intend to take actions reasonably necessary to enforce our patent rights, we may not be able to detect infringement of our own or in-licensed patents, which may be especially difficult for methods of manufacturing or formulation products, and we depend, in part, on our licensors and collaborators to protect a substantial portion of our proprietary rights. In addition, third parties may challenge our in-licensed patents and any of our own patents that we may obtain, which could result in the invalidation or unenforceability of some or all of the relevant patent claims. Litigation or other proceedings to enforce or defend intellectual property rights is very complex, expensive, and may divert our management’s attention from our core business and may result in unfavorable results that could adversely affect our ability to prevent third parties from competing with us.

If another party has reason to assert a substantial new question of patentability against any of our claims in our own and in-licensed patents, the third party can request that the patent claims be reexamined, which may result in a loss of scope of some claims or a loss of the entire patent. In addition to potential infringement suits and, interference and reexamination proceedings, we may become a party to patent opposition proceedings where either the patentability of the inventions subject of our patents are challenged, or we are challenging the patents of others. The costs of these proceedings could be substantial, and it is possible that such efforts would be unsuccessful.

As the medical device, biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that others may assert our commercial product and/or product candidates infringe its patent rights. If a third-party’s patents were found to cover our commercial product and product candidates, proprietary technologies or its uses, we or our collaborators could be enjoined by a court and required to pay damages and could be unable to continue to commercialize our products or use our proprietary technologies unless we or it obtained a license to the patent. A license may not be available to us or our collaborators on acceptable terms, if at all. In addition, during litigation, the patent holder could obtain a preliminary injunction or other equitable relief which could prohibit us from making, using or selling our commercial product and product candidates pending a trial on the merits, which could be years away.

Proprietary trade secrets and unpatented know-how are also very important to our business. Although we have taken steps to protect our trade secrets and unpatented know-how, by entering into confidentiality agreements with third parties, and proprietary information and invention agreements with certain employees, consultants and advisors, third parties may still obtain this information or we may be unable to protect our rights. We also have limited control over the protection of trade

secrets used by our licensors, collaborators and suppliers. There can be no assurance that binding agreements will not be breached, that we would have adequate remedies for any breach, or that our trade secrets and unpatented know-how will not otherwise become known or be independently discovered by our competitors. If trade secrets are independently discovered, we would not be able to prevent its use. Enforcing a claim that a third party illegally obtained and is using our trade secrets or unpatented know-how is expensive and time consuming, and the outcome is unpredictable.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed to us alleged trade secrets of its other clients or former employers. As is common in the biotechnology and pharmaceutical industry, certain of our employees were formerly employed by other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Moreover, we engage the services of consultants to assist us in the development of our commercial product and product candidates, many of whom were previously employed at or may have previously been or are currently providing consulting services to, other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that these employees and consultants or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of its former employers or its former or current customers. Litigation may be necessary to defend against these types of claims. Even if we are successful in defending against any such claims, any such litigation would likely be protracted, expensive, a distraction to our management team, not viewed favorably by investors and other third parties, and may potentially result in an unfavorable outcome.

Risks Related to Our Capital Structure

Our outstanding warrants may result in dilution to our stockholders.

Our outstanding March 2011 and April 2011 warrants to purchase a total of 791,398 shares of common stock as of December 31, 2014 at a current exercise price of $0.65 per share contain so-called full-ratchet anti-dilution provisions. Our outstanding March 2010 and December 2012 warrants to purchase 25,000 and 3,031,311 shares of common stock as of December 31, 2014 at current exercise prices of $2.15 per share and $1.90 per share, respectively, contain so-called weighted-average anti-dilution provisions. These anti-dilution provisions may be triggered by the issuance of the shares being offered hereby or upon any future issuance by us of shares of our common stock or common stock equivalents at a price per share below the then-exercise price of the warrants, subject to some exceptions.

To the extent that these anti-dilution provisions are triggered in the future, we would be required to reduce the exercise price of all of the warrants on either a full-ratchet or weighted-average basis, which would have a dilutive effect on our stockholders.
