NOTES TO CONDENSED FINANCIAL 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 therapies in clinical programs targeting indications such as KRAS/NRAS-mutated metastatic colorectal cancer, metastatic pancreatic cancer, as well as investigator-initiated trials in triple negative breast cancer and small cell lung cancer. 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 the standard-of-care 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, 2022, 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, 2022, included in the Company’s annual report on Form 10-K filed with the SEC on March 2, 2023.
Liquidity
The Company has incurred net losses since its inception and has negative operating cash flows. As of March 31, 2023, the Company had $97.0 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 three months ended March 31, 2023, 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, 2022.
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.
8
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:
| March 31, | |||||||||||
| 2023 | 2022 | ||||||||||
| Options to purchase Common Stock | 6,396,895 | 5,467,611 | |||||||||

| Series E Convertible Preferred Stock | — | 1,342,250 | |||||||||

Recent Accounting Pronouncement Not Yet Adopted
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. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2021 (or December 15, 2023, for companies who meet the SEC definition of Smaller Reporting Companies), and interim periods within those fiscal years. The amendment is to be adopted through either a fully retrospective or modified retrospective method of transition. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its financial statements and related disclosures, and will adopt this standard on January 1, 2024.

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 March 31, 2023, were substantially due to increases 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.

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 KRAS/NRAS-mutated metastatic colorectal cancer ("mCRC") and metastatic pancreatic ductal adenocarcinoma ("mPDAC"), as well as in investigator-initiated trials in triple negative breast cancer ("TNBC") and small cell lung cancer ("SCLC"). 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 clinical evidence of favorable safety and efficacy, with expected on-target, easy to manage and reversible 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 (IC50 = 2nM; IC50 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 (IC50>10,000 nM);
•Onvansertib is orally bioavailable, allowing for relative ease and flexibility of dosing.
17
•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;
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 synergistic effects have been observed in xenograft models of onvansertib in combination with irinotecan, 5-fluorouracil ("5-FU"), abiraterone, PARP inhibitors, venetoclax, and paclitaxel, while additive effects in combination with cytarabine or bevacizumab have been demonstrated. Combining onvansertib with standard of care cancer agents provides opportunities for synergy with many cancer therapies.
There are five ongoing clinical trials of onvansertib: two trials (TROV-054 and ONSEMBLE) in second line treatment in patients with KRAS-mutated Metastatic Colorectal Cancer ("mCRC"), one trial in second line treatment in patients with Metastatic Pancreatic Ductal Adenocarcinoma ("mPDAC"), and two investigator-initiated trials in patients with unresectable locally advanced or metastatic Triple Negative Breast Cancer ("TNBC") and relapsed Small Cell Lung Cancer ("SCLC").
Phase 1b/2 Clinical Trial in KRAS-mutated mCRC
TROV-054 is a Phase 1b/2 open-label multi-center clinical trial of onvansertib in combination with standard of care FOLFIRI and bevacizumab for the second line treatment of patients with KRAS-mutated mCRC, which is being conducted at seven clinical trial sites across the U.S. - USC Norris Comprehensive Cancer Center, The Mayo Clinic Cancer Centers (Arizona, Minnesota, and Florida), Kansas University Medical Center, Inova Schar Cancer Institute and CARTI Cancer Center. This trial completed enrollment in October 2022.
The primary objectives of this trial are 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).
The scientific rationale for this clinical trial is based on the two key principles of synthetic lethality and synergy, with the objective of demonstrating a proof-of-concept of clinical benefit within this Phase 1b/2 trial. Synthetic lethality refers to a critical vulnerability to tumor cell death by way of PLK1 inhibition within CRC tumor cells harboring KRAS mutations versus KRAS wild-type isogenic cells. Synergy occurs when the combination of multiple drugs results in an unexpected greater activity than an expected additive effect of the individual drugs. Onvansertib in combination with two DNA-damaging agents, irinotecan and 5-FU (two components of FOLFIRI), demonstrated synergy in colorectal cancer cell lines and both combinations have demonstrated significantly greater tumor growth inhibition than either drug alone in CRC in vivo models. We believe this synergy occurs because PLK1 can promote the repair of DNA damage caused by chemotherapeutic agents and by inhibiting PLK1, onvansertib leaves damaged tumor cells unable to repair DNA damage from chemotherapy and then replicate. For more information, please visit NCT03829410 at www.clinicialtrials.gov.
Data presented on September 12, 2022, provided an update of the ongoing TROV-054 Phase 1b/2 single arm clinical trial in KRAS-mutated metastatic colorectal cancer:
•Objective response rate ("ORR") across all evaluable patients was 35%, with 17 of 48 evaluable patients achieving an objective response. Responses have been observed across multiple KRAS variants;
•Median duration of response ("mDoR") across all evaluable patients was 11.7 months (95% confidence interval ("CI"): 8.9 – not reached);
•Median progression free survival ("mPFS") across all evaluable patients was 9.3 months (95% CI: 7.6 – 13.5). Historical control trials of different drug combinations, including the standard-of-care ("SOC") of FOLFIRI with bevacizumab, in similar patient populations have shown ORR and mPFS of 5 – 13% and ~4.5 – 5.7 months, respectively.
18
•A subgroup analysis of patients who were bevacizumab naïve when they entered 2nd line therapy vs patients who had received prior bevacizumab in 1st line therapy showed that patients who were bevacizumab naïve (n=13) had an ORR of 69% and mPFS of 13.5 months, which is well above historical controls. In contrast, patients previously treated with bevacizumab (n=35) had an ORR of 23% and mPFS of 7.8 months.
Phase 2 Randomized Clinical Trial in KRAS-mutated mCRC (the ONSEMBLE trial)
The ONSEMBLE trial (CRDF-003), is a Phase 2 open-label, randomized multi-center clinical trial of onvansertib in combination with standard of care FOLFIRI and bevacizumab for the second line treatment of patients with KRAS/NRAS-mutated mCRC. The trial is currently open for enrollment and will be conducted at approximately 40 clinical trial sites across the U.S.
The primary objectives of the ONSEMBLE trial is to evaluate onvansertib’s safety and efficacy in combination with the standard-of-care FOLFIRI/bevacizumab regimen in patients with second-line KRAS/NRAS-mutated mCRC. The trial is expected to enroll approximately 150 patients who will be randomized 1:1:1 to receive standard of care alone, standard of care plus 20 mg onvansertib, or standard of care plus 30 mg onvansertib, with onvansertib administered on days 1-5 and 15-19 of 28-day treatment cycles.
The primary endpoint of the trial is objective response rate, defined as a tumor reduction in size of at least 30% as per RECIST 1.1. Progression-free survival and duration of response will be key secondary endpoints. The trial was activated during the fourth quarter of 2022, with topline data anticipated in the second-half of 2024. For more information, please visit NCT05593328 at www.clinicialtrials.gov.
The first patient was dosed in the ONSEMBLE trial during March 2023.
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 second 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. The first patient was dosed in June 2021.
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 second-line treatment in patients with mPDAC who have failed 1st line gemcitabine-based therapy. The trial is expected to enroll approximately 45 patients. For more information, please visit NCT04752696 at www.clinicialtrials.gov.
Preliminary data presented on September 12, 2022 provided an update of the ongoing CRDF-001 Phase 2 open label clinical trial in mPDAC:
•Preliminary data from 5 evaluable patients showed 1 patient achieving an initial partial response ("PR") and 3 patients achieving stable disease ("SD");
•The 4 patients achieving SD or PR remain on study; the fifth evaluable patient discontinued treatment due to disease progression and an additional 3 patients remain on study awaiting their first post-baseline scan;
•Additional data is expected in mid-2023.
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.
19
The primary endpoint of Phase 2 of the trial is ORR, with PFS included as a secondary endpoint. Preliminary data from the trial are expected in the fourth-quarter of 2023 or first-quarter of 2024. For more information, please visit NCT05383196 at www.clinicialtrials.gov.
Phase 2 Investigator-Initiated Clinical Trial in SCLC
A single-arm, two-stage, Phase 2 trial of onvansertib monotherapy in patients with relapsed SCLC is open for enrollment at the University of Pittsburgh Medical Center ("UPMC"). The trial is designed to enroll 15 patients in Stage 1, with the study proceeding to Stage 2 if 2 or more Stage 1 patients achieve an objective response. Stage 2 is designed to enroll an additional 20 patients. The primary endpoint of the trial is ORR, while key secondary endpoints include PFS and overall survival. Preliminary data from the trial are expected in mid-2023. For more information, please visit NCT05450965 at www.clinicialtrials.gov.

Critical Accounting Policies
Our accounting policies are described in ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS of our Annual Report on Form 10-K as of and for the year ended December 31, 2022, filed with the SEC on March 2, 2023. There have been no changes to our critical accounting policies since December 31, 2022.
Three Months Ended March 31, 2023 and 2022
Revenues
Total revenues were $83,000 for the three months ended March 31, 2023, as compared to $74,000 for the same period in 2022. Revenues are from our sales-based or usage-based royalties on other intellectual property licenses, unrelated to onvansertib. Revenue recognition of the royalty depends on the timing and overall sales activities of the licensees.
Research and Development Expenses
Research and development expenses consisted of the following:

Research and development expenses increased by $1.8 million for the three months ended March 31, 2023, compared to the same period in 2022. The overall increase in expenses was primarily due to costs associated with clinical programs and outside service costs related to the development of our lead drug candidate, onvansertib. Salaries and staff costs increased primarily due to the expansion of our clinical operations team (research and development average headcount grew by 25% over the comparative period). The increase in facilities and other is primarily due to increased allocation of facilities cost resulting from headcount growth compared to the prior period.
Selling, General and Administrative Expenses
Selling, general and administrative expenses consisted of the following:

Selling, general and administrative expenses decreased by $0.9 million for the three months ended March 31, 2023, compared to the same period in 2022. Outside services decreased due to the completion of strategic valuation consulting related to our lead drug candidate, onvansertib, during the prior period. Stock-based compensation decreased due to a change in the timing of stock option grants to our board of directors. Facilities and other costs decreased primarily due to lower insurance costs as compared to the prior period.
Net Loss
Net loss and per share amounts were as follows:

| Weighted average shares outstanding — basic and diluted | 44,677 | 43,231 | 1,446 | ||||||||||||||
The $0.2 million increase in net loss attributable to common shareholders was primarily the result of an increase in operating expenses for the three months ended March 31, 2023, compared to the same period in 2022. There was no change in basic and diluted net loss per share with the addition of 1.4 million shares of common stock issued from April 1, 2022 through March 31, 2023.
LIQUIDITY AND CAPITAL RESOURCES
Net cash used in operating activities for the three months ended March 31, 2023, was $8.7 million, compared to $10.2 million for the three months ended March 31, 2022. Our use of cash was primarily a result of the net loss of $11.2 million for the three months ended March 31, 2023, adjusted for non-cash items related to stock-based compensation of $1.1 million. The net change in our operating assets and liabilities was primarily the result of decreasing cash used in operations of $1.6 million. At our current and anticipated level of operating loss, we expect to continue to incur an operating cash outflow for the next several years.
Net cash provided by investing activities was $7.3 million primarily related to sales and maturities in excess of purchases of marketable securities for the three months ended March 31, 2023, compared to net cash used in investing activities
21
of $18.4 million primarily related to sales and maturities in excess of purchases of marketable securities during the same period in 2022.
Net cash provided in financing activities was $0 for the three months ended March 31, 2023, and 2022.
As of March 31, 2023, and December 31, 2022, we had working capital of $93.6 million and $103.5 million, respectively.
We have incurred net losses since our inception and have negative operating cash flows. As of March 31, 2023, we had $97.0 million in cash, cash equivalents and short-term investments and we believe we have sufficient cash to meet our funding 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 2025.
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.

We have performed an evaluation under the supervision and with the participation of our management, including our principal executive officer (CEO) and principal financial officer (CFO), of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of March 31, 2023, to provide reasonable assurance that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives as specified above. Management does not expect, however, that our disclosure controls and procedures will prevent or detect all errors and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within our company have been detected.
Changes in Internal Control over Financial Reporting
There was no change in our internal control over financial reporting during the three months ended March 31, 2023, that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
