A Phase 2, Randomized, Open-label Study of Onvansertib in Combination With FOLFIRI and Bevacizumab or FOLFOX and Bevacizumab Versus FOLFIRI and Bevacizumab or FOLFOX and Bevacizumab for First-line Treatment of Metastatic Colorectal Cancer in Patients With a KRAS or NRAS Mutation
Description
Brief Summary
The purpose of this study is to assess 2 different doses of onvansertib to select the lowest
dose that is maximally effective, and to assess the safety, efficacy, pharmacokinetics, and
pharmacodynamics of onvansertib in combination with FOLFIRI + bevacizumab or FOLFOX +
bevacizumab in patients with KRAS or NRAS-mutated metastatic colorectal cancer (CRC) in the
first-line setting.
