What was measured

A DLT was defined as occurrence of any treatment-emergent adverse event (TEAE) in Phase 1 Parts 1 and 2. DLT included all TEAE of specified grades such as 1) Hematologic toxicities - any Grade 4 thrombocytopenia or neutropenia, anemia, febrile neutropenia, ≥ Grade 3 hemolysis, thrombocytopenia and 2) Nonhematologic toxicities - Grade 4 AE, nausea, vomiting, or diarrhea, electrolyte abnormality, ≥ Grade 3 aspartate aminotransferase (AST), alanine aminotransferase (ALT), or total bilirubin elevation, Grade 2 AST/ALT with symptomatic liver inflammation, AST or ALT \> 3 × upper limit of normal (ULN) and concurrent total bilirubin \> 2 × ULN without initial findings of cholestasis, and any other ≥ Grade 3 toxicity. A TEAE is any AE either reported for the first time or worsening of a pre-existing event after first dose of study drug and up to 100 days after last dose of study drug.

Analysis population: The Phase 1, Part 1 Safety Population includes all participants enrolled in the study who received at least 1 dose of study drug.
