SAN DIEGO, April  15, 2025  (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 completion of patient enrollment in the ongoing Phase 2 CRDF-004 trial evaluating onvansertib in combination with standard of care (SoC) for the treatment of first-line RAS-mutated metastatic colorectal cancer (mCRC).

“The successful completion of enrollment in our first-line trial for patients with RAS mutant mCRC represents an important milestone in our mission to develop new treatments for a population who have not seen meaningful treatment advancements for decades. We are deeply grateful for our patients, care-givers and clinical investigators, whose commitment to the trial has been integral in this achievement,” said Mark Erlander, Chief Executive Officer of Cardiff Oncology. “As we move forward, we are eager to continue accruing additional clinical data and advancing towards regulatory discussions with FDA with the goal of bringing this transformative therapy to patients.”

The Phase 2 CRDF-004 trial has reached our targeted enrollment of patients with first-line mCRC across 41 clinical sites in the U.S. Patients in the trial have a documented KRAS or NRAS mutation with unresectable disease. Onvansertib is added to SoC consisting of FOLFIRI plus bevacizumab or FOLFOX plus bevacizumab. Patients are randomized 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 (DOR) and safety.

The company anticipates reporting additional clinical data from the CRDF-004 trial in the first half of 2025.

About Cardiff Oncology, Inc.

The Company's lead asset is onvansertib, a PLK1 inhibitor 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 in ongoing and 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 the SoC alone.
