NOTES TO CONDENSED FI NANCIAL STATEMENTS

(Unaudited)

1. Organization and Basis of Presentation

Business Organization and Overview

Cardiff Oncology, Inc. (“Cardiff Oncology” or the “Company”) headquartered in San Diego, California, is a clinical-stage biotechnology company leveraging Polo-like Kinase 1 (“PLK1”) inhibition, to develop novel therapies across a range of cancers. The Company’s lead asset is onvansertib, a PLK1 inhibitor that is being evaluated in combination with standard-of-care ("SoC") therapeutics in clinical programs targeting indications such as RAS-mutated metastatic colorectal cancer (“mCRC”), as well as ongoing or planned investigator-initiated trials in metastatic pancreatic ductal adenocarcinoma (“mPDAC”), small cell lung cancer (“SCLC”), and triple negative breast cancer (“TNBC”). These programs and the Company’s broader development strategy are designed to target tumor vulnerabilities in order to overcome treatment resistance and deliver superior clinical benefit compared to SoC alone. The Company's common stock is listed on the Nasdaq Capital Market under the ticker symbol "CRDF".

Basis of Presentation

The accompanying unaudited interim condensed financial statements of Cardiff Oncology have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) related to a quarterly report on Form 10-Q. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations. The unaudited interim condensed financial statements reflect all adjustments consisting of normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the Company’s financial position and the results of its operations and cash flows for the periods presented. The unaudited condensed balance sheet at December 31, 2023, has been derived from the audited financial statements at that date but does not include all of the information and disclosures required by GAAP for annual financial statements. The operating results presented in these unaudited interim condensed financial statements are not necessarily indicative of the results that may be expected for any future periods. These unaudited interim condensed financial statements should be read in conjunction with the audited financial statements and the notes thereto for the year ended December 31, 2023, included in the Company’s annual report on Form 10-K filed with the SEC on February 29, 2024.

Liquidity

The Company has incurred net losses since its inception and has negative operating cash flows. As of September 30, 2024, the Company had $ 57.7 million in cash, cash equivalents and short-term investments and believes it has sufficient cash to meet its funding requirements for at least the next 12 months following the issuance date of these financial statements.

For the foreseeable future, the Company expects to continue to incur losses and require additional capital to further advance its clinical trial programs and support its other operations. The Company cannot be certain that additional funding will be available on acceptable terms, or at all. To the extent that the Company can raise additional funds by issuing equity securities, the Company’s stockholders may experience additional dilution.

2. Summary of Significant Accounting Policies

During the nine months ended September 30, 2024, there have been no changes to the Company’s significant accounting policies as described in its Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Net Loss Per Share

Basic and diluted net loss per common share is determined by dividing net loss applicable to common stockholders by the weighted-average common shares outstanding during the period. Preferred dividends are included in net loss attributable to common stockholders in the computation of basic and diluted earnings per share.

Table of Contents

The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted net loss per share because their effect was anti-dilutive:


	September 30,
	2024		2023
Options to purchase Common Stock		8,348,344		6,652,427
Warrants to purchase Common Stock		2,807,353		2,807,948
Series A Convertible Preferred Stock		877		877
		11,156,574		9,461,252

Recently Adopted Accounting Pronouncement

In August 2020, the FASB issued ASU No. 2020-06 ("ASU 2020-06"), Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”). ASU 2020-06 eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, ASU 2020-06 modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. This update was effective for the Company on January 1, 2024. The amendment is to be adopted through either a fully retrospective or modified retrospective method of transition. Early adoption is permitted. The Company adopted this standard as of January 1, 2024 using the modified-retrospective method. As a result of the adoption the Company reversed the accretion of preferred stock dividends originally recorded in 2005 related to the Series A Convertible Preferred Stock of $ 793,000 .

3 . Fair Value Measurements

The following table presents the Company’s assets and liabilities that are measured and recognized at fair value on a recurring basis classified under the appropriate level of the fair value hierarchy as of September 30, 2024, and December 31, 2023:

We periodically review our portfolio of debt securities to determine if any investment is impaired due to credit loss or other potential valuation concerns. For debt securities where the fair value of the investment is less than the amortized cost basis, we have assessed at the individual security level for various quantitative factors including, but not limited to, the nature of the investments, changes in credit ratings, interest rate fluctuations, industry analyst reports, and the severity of impairment. Unrealized losses in investments available for sale debt securities at September 30, 2024, were substantially due to changes in interest rates, not due to increased credit risks associated with specific securities. Accordingly, we have not recorded an allowance for credit losses. It is not more likely than not that we will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity.

2021 Equity Incentive Plan

In June 2021 the Company's stockholders approved the 2021 Omnibus Equity Incentive Plan ("2021 Plan"). As of September 30, 2024 the number of authorized shares in the 2021 Plan is equal to the sum of (i) 8,150,000 shares, plus (ii) the number of shares of Common Stock reserved, but unissued under the 2014 Plan; and (iii) the number of shares of Common Stock underlying forfeited awards under the 2014 Plan. As of September 30, 2024 , there were 3,155,783 shares available for issuance under the 2021 Plan.

2014 Equity Incentive Plan

Subsequent to the adoption of the 2021 Plan, no additional equity awards can be made under the terms of the 2014 Plan.

Inducement Grants

The Company issues equity awards to certain new employees as inducement grants outside of its 2021 Plan. As of September 30, 2024, an aggregate of 1,380,248 shares were issuable upon the exercise of inducement grant stock options approved by the Company.

Rescinding and reissuance of March 2024 stock options

On May 30, 2024, the Board of Directors of the Company approved the rescinding of an aggregate of 1,697,712 shares of common stock issuable upon exercise of stock options granted on March 7, 2024 at an exercise price of $ 3.51 per share to employees and officers of the Company. On May 30, 2024, the Board of Directors of the Company approved the grant of an aggregate of 1,697,712 shares of common stock issuable upon exercise of stock options at an exercise price of $ 3.51 per share to employees and officers of the Company, subject to stockholder approval of an increase in the shares of common stock available for issuance pursuant to the Company’s 2021 Equity Incentive Plan at the Company’s annual meeting on June 20, 2024. The increase of shares available was approved by shareholders at the June 20, 2024 meeting, thus completing the requirements for the reissuance of the grant. The terms of the reissued grant were identical to the rescinded grant, therefore the transaction does not represent a stock option modification.

Warrants

A summary of warrant activity and changes in warrants outstanding, classified as equity is presented below:

Research and Development Agreements

In March 2017, the Company entered into a license agreement with Nerviano which granted the Company development and commercialization rights to NMS-1286937, which Cardiff Oncology refers to as onvansertib. Terms of the agreement also provide for the Company to pay development and commercial milestones, and royalties based on sales volume. These potential development milestones include: (a) dosing of the first subject in the first Phase III Clinical Trial for the first Product, a registration enabling Phase II Clinical Trial, or after completion of a Phase II Clinical Trial that is used as the basis for an NDA submission; and (b) upon filing of the first NDA or equivalent for the first product candidate. During the nine months ended September 30, 2024 and 2023 no milestone or royalty payments were made.

The Company is a party to various agreements under which it licenses technology on an exclusive basis in the field of oncology therapeutics. These agreements include License fees, Royalties and Milestone payments. For the nine months ended September 30, 2024 and 2023, payments have not been material. The Company also has a legacy license agreement in the field of oncology diagnostics under which royalty payments are due to the Company. These royalty payments are calculated as a percent of revenue.

Litigation

On May 13, 2024, a purported stockholder of the Company filed a putative class action in the Court of Chancery of the State of Delaware captioned Vrana v. James O. Armitage et al. , C.A. No. 2024-0507-MTZ (Del. Ch.) (“Action”). The Action was mooted on June 20, 2024 when the Company’s stockholders voted: (i) to elect all 7 nominees for director to serve until the 2025 Annual Meeting of Stockholders; and (ii) to approve an amendment to the Company’s 2021 Equity Incentive Plan to increase the number of shares issuable thereunder to 8,150,000 shares. On June 26, 2024, the Court entered an order dismissing the Action but retained jurisdiction solely for the purpose of resolving the plaintiff’s counsel’s anticipated motion for an award of attorneys’ fees and expenses. Without admitting any fault or wrongdoing, the Company agreed to pay $ 400,000 in attorneys’ fees and expenses to the plaintiff’s counsel in connection with the mooted claims. In entering the order, the Court did not review, and did not pass judgment on, the payment of the attorneys’ fees and expenses. The Company paid the plaintiff’s counsel fees and expenses during September 2024, which was recorded within selling general and administrative expense.

From time to time, the Company may become involved in various lawsuits and legal proceedings that arise in the ordinary course of business. Litigation is subject to inherent uncertainties, and an adverse result in matters may arise from time to time that may harm the Company’s business. As of the date of this report, management believes that there are no claims against the Company, which could result in a material adverse effect on the Company’s business or financial condition.

7. Subsequent Events

Sale of Common Stock

From October 1, 2024 through November 4, 2024, the Company sold 2.4 million shares of its common stock under the Sales Agreement with Jefferies LLC. Gross proceeds from these sales was $ 7.0 million .

Overview

We are a clinical-stage biotechnology company leveraging PLK1 inhibition, a well-validated oncology drug target, to develop novel therapies across a range of cancers with the greatest unmet medical need. Our goal is to target tumor vulnerabilities with treatment combinations of onvansertib, our oral and highly selective PLK1 inhibitor, and standard-of-care ("SoC") therapeutics. We are focusing our clinical program in indications such as RAS-mutated metastatic colorectal cancer ("mCRC"), as well as in investigator-initiated ongoing or planned trials in metastatic pancreatic ductal adenocarcinoma ("mPDAC"), small cell lung cancer ("SCLC"), and triple negative breast cancer ("TNBC"). Our clinical development programs incorporate tumor genomics and biomarker assays to refine assessment of patient response to treatment.

Our Lead Drug Candidate, Onvansertib

Onvansertib is an oral, small molecule drug candidate that is highly specific for PLK1 inhibition with a 24-hour half-life.

We believe the attributes of onvansertib described below, as well as early clinical evidence of favorable safety and efficacy, with expected on-target, manageable and transient side effects, may prove beneficial in addressing clinical therapeutic needs across a variety of cancers:

•

Onvansertib is highly potent and highly selective against the PLK1 enzyme (IC 50 = 2nM; IC 50 is the concentration for 50% inhibition), compared to prior PLK1 inhibitors that were pan-inhibitors of several PLK targets. Low or no activity of onvansertib was observed on a panel of 63 kinases (IC50>500 nM), including the PLK members PLK2 and PLK3 (IC 50 >10,000 nM);

•

Onvansertib is orally bioavailable, allowing for relative ease and flexibility of dosing;

•

Onvansertib has a relatively short drug half-life of 24 hours, allowing for flexible dosing and scheduling which has shown favorable safety and tolerability across multiple clinical trials.

Table of Contents

In vitro studies have shown synergistic effects when onvansertib was administered in combination with different cytotoxic agents including microtubule-targeting agents, topoisomerase 1 inhibitors, antimetabolites, alkylating agents, proteasome inhibitors, kinase inhibitors, PARP inhibitors, BCL-2 inhibitors, and androgen biosynthesis inhibitors.

In addition, in vivo combination studies have confirmed the positive results obtained in vitro and additive or synergistic effects on efficacy have been observed in xenograft models of onvansertib in combination with irinotecan, 5-fluorouracil ("5-FU"), abiraterone, PARP inhibitors, venetoclax, paclitaxel, or bevacizumab. Combining onvansertib with SoC cancer agents provides opportunities for synergy with many cancer therapies.

There are several ongoing and planned clinical trials of onvansertib in multiple indications: one trial (CRDF-004) in first-line treatment in patients with RAS-mutated mCRC, and investigator-initiated trials in first-line mPDAC, relapsed SCLC and unresectable locally advanced or metastatic TNBC.

RAS-mutated mCRC Program:

CRDF-004 Randomized Clinical Trial in First-Line RAS-mutated mCRC

CRDF-004 is a Phase 2 open-label, randomized multi-center clinical trial of onvansertib in combination with SoC FOLFIRI and bevacizumab or FOLFOX and bevacizumab for the first-line treatment of patients with RAS-mutated mCRC. The primary objectives of the CRDF-004 trial are to evaluate onvansertib’s safety and efficacy in combination with the SoC, as well as to evaluate two doses of onvansertib, 20mg and 30mg, given in combination with SoC, against SoC alone. The primary endpoint of the trial is objective response rate ("ORR"). Progression-free survival and duration of response will be secondary endpoints. We anticipate releasing initial data from the CRDF-004 trial in the fourth quarter of 2024. This trial is conducted in partnership with Pfizer Ignite, an end-to-end service for biotech companies, and it is expected to enroll approximately 90 evaluable patients. In February 2024 it was announced that the first patient dosed for this trial. For more information, please visit NCT06106308 at www.clinicialtrials.gov .

Contingent upon the results of CRDF-004, we plan to initiate CRDF-005, a Phase 3, randomized trial with registrational intent. The FDA has agreed that a seamless trial with ORR at an interim point is an acceptable endpoint to pursue accelerated approval, with progression-free survival and trend in overall survival being the endpoints for full approval.

Phase 1b/2 Clinical Trial in Second-Line KRAS-mutated mCRC

TROV-054, a Phase 1b/2 open-label multi-center clinical trial of onvansertib in combination with SoC FOLFIRI and bevacizumab for the second-line treatment of patients with KRAS-mutated mCRC, completed enrollment in October 2022.

The primary objectives of this trial were to evaluate the Dose-Limiting Toxicities ("DLTs"), maximum tolerated dose ("MTD") and recommended Phase 2 dose ("RP2D") of onvansertib in combination with FOLFIRI and bevacizumab (Phase 1b) and to continue to assess the safety and preliminary efficacy of onvansertib in combination with FOLFIRI and bevacizumab patients with KRAS-mutated mCRC (Phase 2). For more information, please visit NCT03829410 at www.clinicialtrials.gov .

Data presented on August 7, 2023, provided an update of the ongoing TROV-054 Phase 1b/2 single arm clinical trial in KRAS-mutated metastatic colorectal cancer:

•

ORR across all evaluable patients was 29%, with 19 of 66 evaluable patients achieving an objective response. Responses have been observed across multiple KRAS variants;

•

Median duration of response ("mDoR") across all evaluable patients was 12.0 months (95% confidence interval ("CI"): 8.9 – not reached);

•

Median progression free survival ("mPFS") across all evaluable patients was 9.3 months (95% CI: 7.8 – 14). Historical control trials of different drug combinations, including the SoC of FOLFIRI with bevacizumab, in similar patient populations have shown ORR and mPFS of 5 – 13% and ~4.5 – 6.7 months, respectively;

•

A subgroup analysis of patients who were bevacizumab naïve when they entered second-line therapy vs. patients who had received prior bevacizumab in first-line therapy showed that patients who were bevacizumab naïve (n=15) had an ORR of 73% and mPFS of 15 months, which is well above historical controls. In contrast, patients previously treated with bevacizumab (n=51) had an ORR of 16% and mPFS of 7.8 months;

Table of Contents

•

Data on Treatment Emergent Adverse Events ("TEAEs") on the trial showed that onvansertib is well-tolerated when used in combination with FOLFIRI and bevacizumab. The more severe, grade 4 TEAEs are either neutropenia or leukopenia, which are common events in patients treated with FOLFIRI and bevacizumab. None of the patients with grade 4 TEAEs discontinued treatment due to their condition and all resolved without issue. There were no major or unexpected toxicities seen in the trial;

•

Data from the Phase 1b portion of this trial was published in the peer-reviewed journal Clinical Cancer Research, February 6, 2024 edition;

•

Data from the Phase 2 portion of this trial was published online in the peer-reviewed journal of Clinical Oncology on October 30, 2024.

Based on the interim results of the TROV-054 trial, we previously designed the ONSEMBLE trial (CRDF-003) as the next phase of our mCRC program. Upon further review of the clinical data from the bevacizumab naïve subgroup (those patients who did not receive bevacizumab in their first-line therapy), the preclinical data on the mechanism of action and the feedback from the FDA on our clinical development strategy, we made the decision to discontinue enrollment in the ONSEMBLE trial and to initiate the CRDF-004 clinical trial.

Phase 2 Clinical Trial in Second-Line RAS-mutated mCRC

The ONSEMBLE trial (CRDF-003) is a Phase 2 randomized, open-label multi-center clinical trial of onvansertib in combination with SoC FOLFIRI and bevacizumab for the second-line treatment of patients with RAS-mutated mCRC. The primary objectives of the ONSEMBLE trial are to evaluate onvansertib’s safety and efficacy in combination with FOLFIRI and bevacizumab, as well as to evaluate two doses of onvansertib, 20mg and 30mg, given in combination with FOLFIRI and bevacizumab, against FOLFIRI and bevacizumab alone. The primary endpoint of the trial is ORR. For more information, please visit NCT05593328 at www.clinicialtrials.gov .

The ONSEMBLE trial enrollment was closed in August 2023 as part of our shift to a first-line mCRC program, and the 23 patients enrolled continued treatment per protocol.

Data presented on February 29, 2024, provided the first update of the ongoing ONSEMBLE Phase 2 randomized clinical trial in RAS-mutated mCRC:

•

ORR data for each arm of the trial and for the two experimental arms combined are shown in the table below. The table also presents ORR data for two subgroups of patients: those who were bevacizumab naïve when they entered second-line therapy vs. patients who had received prior bevacizumab in first-line therapy.


Objective Response Rate	Bevacizumab Naïve Patients (1)	Bevacizumab Exposed Patients	All Patients
FOLFIRI/bev (SoC alone); (N=6)	0% (0 of 3)	0% (0 of 3)	0% (0 of 6)
Onvansertib 20mg + SoC; (N=8)	50% (1 of 2)	0% (0 of 6)	13% (1 of 8)
Onvansertib 30mg + SoC; (N=7)	50% (1 of 2)	0% (0 of 5)	14% (1 of 7)
Onvansertib (all doses) + SoC; (N=15)	50% (2 of 4)	0% (0 of 11)	13% (2 of 15)

(1)

The two partial responses were confirmed on the patients' subsequent scans.

•

Data on TEAEs on the trial showed that onvansertib is well-tolerated when used in combination with FOLFIRI and bevacizumab. No Grade 4 TEAEs were observed for the arms of FOLFIRI and bevacizumab alone and onvansertib 30mg given in combination with FOLFIRI and bevacizumab. Two Grade 4 TEAEs of neutropenia were seen in patients receiving 20mg onvansertib given in combination with FOLFIRI and bevacizumab. Both patients recovered within 7 and 10 days after withholding the study treatment and no dose reductions in subsequent treatment cycles were needed. There were no major or unexpected toxicities seen in the trial.

The ORR data from the randomized ONSEMBLE trial validates the findings observed in our earlier single-arm Phase 1b/2 KRAS-mutated mCRC trial (TROV-054). In the ONSEMBLE trial, objective responses were observed only in bevacizumab naïve patients versus bevacizumab exposed patients. In addition, these objective responses were present only in bevacizumab naïve patients randomized to the experimental arms of onvansertib in combination with FOLFIRI and bevacizumab vs. bevacizumab naïve patients randomized to the FOLFIRI and bevacizumab alone control arm.

mPDAC Program:

Phase 2 Investigator-Initiated Clinical Trial in First-Line mPDAC

In February 2024, the FDA approved NALIRIFOX as a first-line treatment option for mPDAC. As a result, we are currently planning to support a new investigator-initiated mPDAC Phase 2 trial of onvansertib in combination with first-line SoC NALIRIFOX, details of which we will announce when available. The trial would replace a previously planned two-cohort, non-randomized Phase 2 trial of onvansertib in combination with first-line SoC Gemzar ® and Abraxane ® which was to be conducted at the OHSU Knight Cancer Institute.

Phase 2 Clinical Trial in mPDAC

CRDF-001 is a Phase 2 open-label multi-center clinical trial of onvansertib in combination with nanoliposomal irinotecan (Onivyde ® ), leucovorin, and fluorouracil for 2 nd line treatment of patients with mPDAC, which is being conducted at six clinical trial sites across the U.S. – The Mayo Clinic Cancer Centers (Arizona, Minnesota, and Florida), Kansas University Medical Center, Inova Schar Cancer Institute, and the University of Nebraska Medical Center. Enrollment for this trial closed in October 2023.

The objective of this trial is to assess the safety and preliminary efficacy of onvansertib in combination with nanoliposomal irinotecan (Onyvide ® ), 5-FU and leucovorin as a 2 nd line treatment in patients with mPDAC who have failed first-line gemcitabine-based therapy. For more information, please visit NCT04752696 at www.clinicialtrials.gov .

Preliminary data presented on September 26, 2023 provided an update of the ongoing CRDF-001 Phase 2 open label clinical trial in mPDAC:

•

Preliminary data from 21 patients evaluable for radiographic response showed 1 patient achieving a confirmed partial response (“PR”) and 3 patients achieving unconfirmed PR that were awaiting confirmatory scans;

•

19% objective response rate ORR achieved compared to historical control of 7.7% in second-line setting;

•

5.0 months mPFS achieved compared to historical control of 3.1 months with SoC;

An update provided on February 29, 2024 indicated 3 of the 4 PRs are confirmed PRs and 1 of the 4 PRs did not confirm on their subsequent scan.

Other Clinical Programs:

Phase 2 Investigator-Initiated Clinical Trial in SCLC

A single-arm, two-stage, Phase 2 trial of onvansertib monotherapy in patients with relapsed SCLC at the University of Pittsburgh Medical Center ("UPMC"), completed enrollment in July 2023.In October 2024, the trial was re-opened for enrollment at the University of Maryland Greenebaum Comprehensive Cancer Center (“UMGCCC”) following the investigator’s relocation to this location. The primary endpoint of the trial is ORR, while key secondary endpoints include PFS and overall survival. For more information, please visit NCT05450965 at www.clinicialtrials.gov .

An examination of the safety data from the first six patients by the institutional review board confirmed the trial can continue to enroll as planned. Preliminary efficacy data for seven patients presented on September 26, 2023, showed one confirmed PR, three stable disease (“SD”) and three progressive disease (“PD”). The disease control rate (“DCR”), including PR and SD, is 57% (4 of 7 patients).

Phase 1b/2 Investigator-Initiated Clinical Trial in TNBC

A single-arm, Phase 1b/2 trial of onvansertib in combination with paclitaxel in patients with unresectable locally advanced or metastatic TNBC is open for enrollment at Dana Farber Cancer Institute ("DFCI"). In Phase 1b, approximately 14-16 patients will be treated with different doses of onvansertib in combination with a fixed dose of paclitaxel to determine the maximum tolerated dose and RP2D of onvansertib. In Phase 2, approximately 34 patients will be treated with the selected onvansertib RP2D in combination with paclitaxel.

The primary endpoint of Phase 2 of the trial is ORR, with PFS included as a secondary endpoint. For more information, please visit NCT05383196 at www.clinicialtrials.gov .

Three Months Ended September 30, 2024 and 2023

Revenues

Total revenues were $0.2 million for the three months ended September 30, 2024, as compared to $0.1 million for the prior period. Revenues are from our sales-based or usage-based royalties on other intellectual property licenses, unrelated to onvansertib.

LIQUIDITY AND CAPITAL RESOURCES

As of September 30, 2024, and December 31, 2023, we had working capital of $46.8 million and $67.0 million, respectively.

We have incurred net losses since our inception and have negative operating cash flows. As of September 30, 2024, we had $57.7 million in cash, cash equivalents and short-term investments and we believe we have sufficient cash to meet our funding

Table of Contents

requirements for at least the next 12 months following the issuance date of this Quarterly Report on Form 10-Q. Based on our current projections we expect that our capital resources are sufficient to fund our operations into the first quarter of 2026.

From October 1, 2024 through November 4, 2024, we raised gross proceeds of $7.0 million from the sale of 2.4 million shares of our Common Stock.

Our drug development efforts are in their early stages, and we cannot make estimates of the costs or the time that our development efforts will take to complete, or the timing and amount of revenues related to the sale of our drug candidates. The risk of completion of any program is high because of the many uncertainties involved in developing new drug candidates to market, including the long duration of clinical testing, the specific performance of proposed products under stringent clinical trial protocols, extended regulatory approval and review cycles, our ability to raise additional capital, the nature and timing of research and development expenses, and competing technologies being developed by organizations with significantly greater resources.

For the foreseeable future, we expect to continue to incur losses and require additional capital to further advance our clinical trial programs and support our other operations. We cannot be certain that additional funding will be available on acceptable terms, or at all. To the extent that we can raise additional funds by issuing equity securities, our stockholders may experience additional dilution.
