- Pfizer Ignite is responsible for the clinical execution of the trial -

- Initial topline results expected in mid-2024 –

- Company will hold a conference call today at 4:30 p.m. ET/1:30 p.m. PT -

SAN DIEGO, Feb. 29, 2024 (GLOBE NEWSWIRE) -- Cardiff Oncology, Inc. (Nasdaq: CRDF), a clinical-stage biotechnology company leveraging PLK1 inhibition to develop novel therapies across a range of cancers, today announced that the first patient was dosed in its randomized first-line Phase 2 trial, CRDF-004, for patients with RAS-mutated metastatic colorectal cancer (mCRC). The trial, whose clinical execution is being conducted by Pfizer Ignite, Pfizer’s new end-to-end service for biotech companies, 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.

“Today’s announcement represents an important milestone for Cardiff Oncology and for patients with RAS-mutated mCRC, who have had no new therapies approved in almost 20 years,” said Fairooz Kabbinavar, MD, FACP, Chief Medical Officer of Cardiff Oncology. “Based on the encouraging results from our Phase 1b/2 trial in second-line KRAS-mutated mCRC and our preclinical data demonstrating the powerful impact of combining onvansertib and bevacizumab, we believe the addition of onvansertib in the first-line setting has the potential to provide a meaningful improvement to the efficacy of SoC for mCRC patients with a RAS-mutation. We are especially pleased with the opportunity to leverage Pfizer Ignite’s execution capabilities to advance the development of onvansertib. We strongly believe that we are on the cusp of a transformative advance in the treatment landscape for mCRC.”

The Phase 2 trial includes patients with mCRC who have a documented KRAS or NRAS mutation. Onvansertib will be added to SoC FOLFIRI plus bevacizumab or FOLFOX plus bevacizumab. A total of 90 patients will be randomized in a 1:1:1 ratio to either 20mg of onvansertib plus SoC, 30mg of onvansertib plus SoC, or SoC alone. The primary endpoint is objective response rate (ORR), and the secondary endpoints include progression-free survival (PFS), duration of response and safety.
