Study Endpoints

Primary Endpoints

Number of participants who experience one or more dose-limiting toxicities (DLTs)
Cycle 1 (Up to approximately 21 days); each cycle is 21 days.

The following events will be considered a DLT unless clearly due to underlying disease or extraneous causes: Grade 4 neutropenia lasting \>7 days; Grade 3 or higher thrombocytopenia associated with clinically significant bleeding, regardless of duration; All Grade 3 or higher nonhematologic toxicities (with exceptions); Any abnormality that results in a drug induced liver injury; Febrile neutropenia Grade 3 or 4; Prolonged delay (\>2 weeks) in initiating treatment after the first 21 days due to intervention-related toxicity; Any intervention-related toxicity that causes the participant to discontinue intervention during the first 21 days; Grade 5 toxicity. The number of participants who experience a DLT will be presented.

Number of participants who experience one or more adverse events (AEs)
Up to approximately 35 months

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.

Number of participants who discontinue study intervention due to an AE
Up to approximately 35 months

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
