What was measured

A DLT was defined as the occurrence of any protocol-defined toxicities occurring during the first study drug treatment cycle, from C1D1 up to and including Cycle 1 Day 28 (per regimen cycle schedule), except those with a clear alternative explanation (e.g., disease progression) or transient (≤72 hours) abnormal laboratory values without associated clinically significant signs or symptoms based on investigator determination.

Analysis population: DLT Evaluable Population: all participants in the FAS Population who met the following criteria: observed for at least the first treatment cycle (i.e., 28 days); received ≥75% of doses of study treatment at the level assigned to that cohort (i.e., 21 days of treatment) or had a DLT during the first study treatment cycle; did not receive any strong or potent CYP3A4/5 inhibitor or inducer during the first study drug treatment cycle (DLT assessment period); was not part of a backfill cohort
