Cardiff Oncology's Promising Data Signals Hope for mCRC Patients
Positive Results from Cardiff Oncology's Clinical Trial
Initial findings from the randomized Phase 2 CRDF-004 trial investigating the combination of onvansertib and standard of care (SoC) for RAS-mutated metastatic colorectal cancer (mCRC) have demonstrated significant promise. The data indicated a remarkable objective response rate (ORR) of 64% for patients receiving a 30mg dose of onvansertib, compared to 33% for those on SoC alone.
This promising development suggests that the 30mg dosage of onvansertib not only outperformed the 20mg dose, which achieved a 50% ORR, but also resulted in deeper tumor regression for patients receiving the higher dosage. Importantly, tolerance levels were excellent across both dosing arms, ensuring manageable side effects.
Understanding the CRDF-004 Trial Design
The CRDF-004 trial is significant as it assesses patients with mCRC possessing documented KRAS or NRAS mutations. Participants are randomized in a 1:1:1 manner into three groups: one group receives 20mg of onvansertib along with SoC treatment, another receives 30mg of onvansertib with SoC, and the last group receives SoC alone. The primary focus of this study is to evaluate the objective response rate (ORR), while secondary outcomes include progression-free survival (PFS), duration of response (DOR), and safety.
Efficacy Results
As of the latest data cut-off, the objective response rates achieved in the trial are noteworthy:
- Control Arm (SoC alone): 33% ORR
- 20mg dose of onvansertib + SoC: 50% ORR
- 30mg dose of onvansertib + SoC: 64% ORR
- All onvansertib patients combined: 57% ORR
Visual representations of patient outcomes through spider plots clearly illustrate the depth of tumor responses for those administered the 30mg dose of onvansertib in conjunction with SoC.
Safety and Tolerability During Trials
Regarding the safety profile, onvansertib combined with standard chemotherapy showcased an excellent tolerability profile, with no major or unforeseen toxicities reported. This robustness strengthens its candidacy to reshape how first-line treatment is administered to nearly 50,000 new RAS-mutated mCRC patients diagnosed annually in the U.S.
Mark Erlander, CEO of Cardiff Oncology, expressed optimism about these findings, stating that the ongoing data supports the belief that onvansertib could revolutionize treatment paradigms in the mCRC community. The combination with established treatment regimens, including FOLFIRI and FOLFOX, highlights how onvansertib stands out against prior PLK1 inhibitors, offering a distinct advantage.
Looking Ahead: Future Milestones
Looking forward, Cardiff Oncology expects additional clinical data from the CRDF-004 trial in the first half of 2025. This update is highly anticipated by the medical and investment communities alike as it stands to provide further insights into onvansertib's potential effectiveness and impact.
Upcoming Conference Call and Webcast
In light of this favorable progress, Cardiff Oncology is set to hold a conference call and live webcast to discuss these results further. The session will commence at 8:00 a.m. ET, and participants can tune in via the company’s website.
