Randomized Ph 2 trial of onvansertib + SoC FOLFIRI/bevacizumab announced in 2L RAS-mutated mCRC

“We designed our next clinical program in mCRC, a randomized Phase 2 trial we have named ONSEMBLE, to accelerate and de-risk our lead indication,” said Mark Erlander, PhD, chief executive officer of Cardiff Oncology. “Chief among ONSEMBLE’s objectives is to generate a randomized dataset to demonstrate the contribution of onvansertib over standard-of-care alone, validating the Phase 1b/2 trial results. These results show patients with different KRAS mutations experiencing durable responses to treatment with onvansertib plus standard-of-care, with an objective response rate and median progression-free survival that are well above historical benchmarks. In line with the FDA’s Project Optimus initiative, the ONSEMBLE trial will also seek to confirm the optimal dose of onvansertib in mCRC. We believe achieving these objectives could position onvansertib for a possible accelerated approval opportunity, though this would ultimately depend on the strength of the ONSEMBLE trial results.”
