Study Endpoints
Primary Endpoints
Incidence and severity of dose-limiting toxicities (DLTs)
28 days

A DLT is defined as an adverse event or abnormal laboratory value of Common Terminology Criteria for Adverse Events (CTCAE) grade ≥ 3 that occurs within the first 28 days and not clearly and incontrovertibly assessed as due to disease progression, intercurrent illness, concomitant medication, or extraneous causes with the exceptions defined in the study protocol. Other clinically significant toxicities may be considered to be DLTs, even if not CTCAE grade 3 or higher.

Incidence and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs)
Up to approximately 24 months

Incidence and severity of AEs and SAEs, including changes in laboratory values, vital signs and electrocardiograms (ECGs) qualifying and reported as AEs.

Frequency of dose interruptions and reductions
Up to approximately 24 months

Number of participants with dose interruptions and/or reductions to assess the tolerability.

Dose intensity
Up to approximately 24 months

Dose intensity defined as the ratio of actual cumulative dose received and actual duration of exposure.

Secondary Endpoints
Overall Response Rate (ORR)
Up to approximately 24 months
Disease Control Rate (DCR)
Up to approximately 24 months
Radiological Progression Free Survival (rPFS)
Up to approximately 24 months
