Pre-assignment details
This Phase 2 study (RMC-4630-03) had a safety run-in period in which RMC-4630 was administered at 140 mg twice weekly (BIW) on D1D2 of each week in a 21-day cycle and sotorasib 960 mg once daily (QD) in a 21-day cycle as the starting dose with the option of escalating to RMC-4630 200 mg BIW on D1D2 of each week in a 21-day cycle. Patients were evaluated for dose limiting toxicities (DLTs).

|---|---|
| RMC-4630 140 mg BIW D1D2 + Sotorasib 960 mg QD The two arms have been broken down per dose level rather than by phase or cohort per the CSR, which is provided to FDA and not uploaded to ct.gov. Participants were administered 140 or 200 mg of RMC-4630 twice weekly (BIW) on D1D2 of each week in a 21-day cycle and Sotorasib 960 mg once daily (QD) in a 21-day cycle. The 140mg and 200mg dose levels were explored at the safety run-in stage, and after completion of the safety run-in (DLT clearance) of both dose levels, additional patients were enrolled at both dose levels for the purpose of dose optimization before selecting the final expansion dose. Therefore, both the 140mg and 200mg dose levels included patients in the safety-run in and dose optimization. After that, 200mg was identified as the RP2D dose, which moved to the expansion phase.
Statistical analysis for all sections in the results was performed for all treated patients by dose level, i.e., 140mg vs 200mg. For patients enrolled at the RP2D dose level of 200mg, analysis was further performed based on mutation status, i.e., cohorts 1 vs 2. | 4 |
