What was measured

During the lead-in period, INCB099280 was administered as monotherapy. During the treatment period, INCB099280 and adagrasib were coadministered. Cmax,ss was defined as the maximum plasma concentration of INCB099280 at steady state. Lead-in Period: Day -1 and Cycle 1 Day 8: predose and 0.5, 1, 2, 3, 4, 6, 8, and 12 hours postdose; predose on Day 1 of Cycles 1, 2, 4, 6, 8, 12, and every fourth cycle thereafter. Without Lead-in Period: Cycle 1 Day 8: predose and 1, 2, and 4 hours postdose; predose on Day 1 of Cycles 1, 2, 4, 6, 8, 12, and every fourth cycle thereafter.
