(Nasdaq: CRDF), a clinical-stage biotechnology company leveraging PLK1 inhibition to develop novel therapies across a range of cancers, today announced financial results for the fourth quarter and full year ended December 31, 2023, and provided a business update. “2024 is a pivotal year for Cardiff Oncology and we are excited for our upcoming randomized data readout from our lead program in first-line mCRC later this year,” said Mark Erlander, Ph.D., Chief Executive Officer of Cardiff Oncology. “The mCRC data we shared in August 2023, and the ONSEMBLE data we are disclosing today, demonstrates onvansertib’s contribution to the standard of care of bevacizumab (bev) and chemotherapy in treating RAS-mutated mCRC. Given there have been no new therapies approved in this large cancer indication in the last 20 years, 2024 marks a critical step in realizing onvansertib’s potential to provide clinical benefit to the large number of newly-diagnosed RAS-mutated mCRC patients, and create value for the stakeholders in our company.” Upcoming expected milestones First-line RAS-mutated mCRC randomized data readout expected in mid-2024 Company highlights for the quarter ended December 31, 2023, and subsequent weeks include: Provided a clinical update on Phase 2 randomized second-line ONSEMBLE trial in mCRC. New clinical data from discontinued second-line randomized ONSEMBLE trial provides further evidence of onvansertib’s improvement of the efficacy for standard of care therapy in bev naïve patients. In the trial, patients who were bev naïve demonstrated an objective response rate (ORR) of 50% on onvansertib. No clinical responses were observed in patients who received standard of care with FOLFIRI/bev or patients who were previously exposed to bev. For additional information, please refer to the press release issued by the Company today which provided an update on the ONSEMBLE trial.Announced first patient dosed in its randomized first-line Phase 2 trial, CRDF-004, for patients with RAS-mutated metastatic colorectal cancer. The trial, whose clinical execution is being conducted by Pfizer Ignite, is designed to confirm the dose of onvansertib for a subsequent registrational trial, and generate safety and efficacy data for onvansertib when added to standard of care (SoC) vs. SoC alone. Interim topline results from CRDF-004 are expected in mid-2024. Contingent upon the results, Cardiff Oncology will initiate a Phase 3, randomized trial, CRDF-005, with registrational intent.Announced the publication of data from Phase 1b study in second line KRAS-mutated mCRC in Clinical Cancer Research. The findings of the Phase 1b portion of the Phase 1b/2 study for the second-line treatment of patients with KRAS-mutated metastatic colorectal cancer disclosed by Cardiff Oncology in August 2023 have been published in the peer-reviewed journal Clinical Cancer Research, a journal of the American Association for Cancer Research. Full Year 2023 Financial Results: Liquidity, cash burn, and cash runway As of December 31, 2023, Cardiff Oncology had approximately $75 million in cash, cash equivalents, and short-term investments. Net cash used in operating activities for the full year 2023 was approximately $30.9 million, a decrease of approximately $2.9 million from $33.8 million for the same period in 2022. Based on its current expectations and projections, the Company believes its current cash resources are sufficient to fund its operations into Q3 2025. Operating results Total operating expenses were approximately $45.9 million for the full year ended December 31, 2023, an increase of $5.6 million from $40.3 million for the same period in 2022. The increase in operating expenses was primarily due to costs associated with clinical programs and outside service costs related to the development of our lead drug candidate, onvansertib, and higher salaries and staff costs primarily due to increased headcount and stock-based compensation for additional grants to employees.
