"This quarter has been exciting as our Phase 2 clinical trial in second-line KRAS-mutant mCRC was published in one of the most esteemed medical journals in the field of oncology, Journal of Clinical Oncology. Our findings demonstrated that onvansertib combined with FOLFIRI/bev was well-tolerated, and revealed a 7.7x greater clinical benefit in bev naïve patients compared to patients who were previously treated with bev," said Mark Erlander, Ph.D., Chief Executive Officer of Cardiff Oncology. "We believe the results of our JCO publication validate our ongoing CRDF-004 trial evaluating onvansertib + chemo for the treatment of mCRC in the first-line setting, where all patients are bev naïve. Furthermore, we are pleased with the progress we have made in the trial as we leverage Pfizer’s resources and capabilities, and are grateful for the commitment from the patients and investigators at our trial sites across the U.S. As of today, the trial continues to generate patient data that will allow us to provide an initial data release by the end of the year. Overall, we are optimistic about onvansertib’s potential to become a meaningful treatment option for the 50,000 new patients diagnosed with RAS-mutated mCRC in the U.S. every year who have not had access to any new treatment options in several decades."
Upcoming expected milestones
•
First-line RAS-mutated metastatic colorectal cancer (mCRC) randomized initial data readout from the CRDF-004 trial expected by end of 2024
Company highlights for the quarter ended September 30, 2024 and subsequent weeks include:
•
Published clinical data of the combination of onvansertib with FOLFIRI and bev in second-line KRAS mutant mCRC in the peer-reviewed Journal of Clinical Oncology, the flagship publication of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper)
•
Phase 2 clinical trial treating patients with KRAS-mutant mCRC (NCT03829410) demonstrated that onvansertib combined with FOLFIRI and bev was well-tolerated, and exhibited clinical activity in the second-line setting.
•
A post hoc analysis revealed a greater clinical benefit in bev naïve patients, who demonstrated an ORR of 77% and mPFS of 14.9 months compared to an ORR of 10% and mPFS of 6.6 months in those previously exposed to bev.
•
Published promising preclinical data demonstrating the combination of onvansertib and alpelisib in PIK3CA-mutated HR-positive breast cancer resistant to palbociclib and endocrine therapy in the peer-reviewed journal, Cancers
•
The combination of onvansertib and alpelisib synergistically inhibited cell viability, suppressed PI3K signaling, and induced G2/M arrest and apoptosis in PI3K-activated cell lines.
•
The combination demonstrated superior anti-tumor activity compared to the single agents in three PDX models.
•
Pharmacodynamic studies confirmed inhibition of both PLK1 and PI3K activity and pronounced apoptosis in the combination-treated tumors.
•
The findings support that targeting PLK1 and PI3Kα with onvansertib and alpelisib, respectively, may be a promising strategy for patients with PIK3CA-mutant HR+ breast cancer failing ET + CDK4/6i therapies and warrant clinical evaluation.
Third Quarter 2024 Financial Results
Liquidity, cash burn, and cash runway
As of September 30, 2024, Cardiff Oncology had approximately $57.7 million in cash, cash equivalents, and short-term investments.
Net cash used in operating activities for the third quarter of 2024 was approximately $10.5 million, an increase of approximately $2.5 million from $8.0 million for the same period in 2023.
Based on its current expectations and projections, the Company believes its current cash resources are sufficient to fund its operations into Q1 2026.
Operating results
Total operating expenses were approximately $12.8 million for the three months ended September 30, 2024, an increase of $1.8 million from $11.0 million for the same period in 2023. The increase in operating expenses was primarily due to clinical programs and outside service costs related to the development of our lead drug candidate, onvansertib.
