Study Endpoints
Primary Endpoints
Progression-Free Survival (PFS)
Up to approximately 38 months

PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first as per the Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1). PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. RECIST 1.1 is modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. PFS as assessed by blinded independent central review (BICR) will be presented.

Overall Survival (OS)
Up to approximately 48 months

OS is defined as the time from randomization to death due to any cause.

Secondary Endpoints
Objective Response (OR)
Up to approximately 38 months
Duration of Response (DOR)
