Study Endpoints

Primary Endpoints

Part 1: Occurrence of Dose Limiting Toxicities (DLTs)
Up to approximately 12 months

Toxicities occurring during Part 1 will define tolerability. DLTs will be assessed for severity by the investigator using CTCAE v5.0 criteria.

Number of Participants With Treatment Emergent Adverse Events (TEAEs)
Up to approximately 12 months

TEAE is any Adverse Event (AE) either reported for the first time or worsening of a pre-existing event after first dose of study drug.

Number of Participants with Dose Interruptions due to TEAE
Up to approximately 12 months

Dose interruptions will occur according to protocol guidelines.

Number of Participants discontinue study due to TEAE
Up to approximately 12 months

TEAE is defined as any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment.

Secondary Endpoints

Objective Response Rate (ORR)
Up to 12 months
Disease Control Response (DCR)
Up to 12 months
Duration of Response (DOR)
Up to 12 months
