Primary Endpoints

Number of Participants Experiencing Dose Limiting Toxicities (DLTs)
Baseline (Day 1) up to 28 days

A DLT was a toxicity, considered possibly related to alobresib, and which occurred during DLT assessment window (Day 1 through Cycle 1 Day 28) in each cohort: Grade ≥ 4 neutropenia (absolute neutrophil count \[ANC\] \< 500/mm\^3); Grade ≥3 neutropenia (ANC\< 1000/mm\^3) with fever (a single temperature of \> 38.3°C or a sustained temperature of ≥ 38°C for more than 1 hour \[hr\]); Grade ≥ 3 thrombocytopenia; Grade ≥ 2 bleeding; Grade ≥ 3 non hematologic toxicity, except Grade 3 nausea or emesis with maximum duration of 48 hrs on adequate medical therapy and Grade 3 diarrhea which persists for \< 72 hrs in absence of maximal medical therapy; Grade ≥ 2 non hematologic treatment-emergent adverse event (TEAE) of potential clinical significance; treatment interruption ≥ 7 days due to unresolved toxicity; and any Grade 3 or 4 elevation in aspartate aminotransferase (AST) or alanine aminotransferase (ALT) associated with a Grade 2 elevation in bilirubin that is at least possibly related to alobresib.
