    Blood samples obtained at baseline and subsequent time points will be analyzed for the presence of circulating tumor DNA (ctDNA [including Kras mutations]).

  7. Phase 2: Maximal Plasma Concentration (Cmax) of Onvansertib [ Time Frame: Pre-dose on Day 1 and 2-4 hours post-dose on Day 5 of Cycles 1, 3 and 5 (cycle is 28 days) ]

  3. Formalin-fixed, paraffin-embedded (FFPE) tumor tissue must be available for submission to a central laboratory in order for a participant to be eligible. If no archival tissue biopsy is available the participant must have a biopsy obtained at screening.
