SECONDARY outcome

Timeframe: Baseline to approximately 3 years postdose

Population: Best overall response and response rates were assessed in the Full Analysis Set.

As per Response Evaluation Criteria for Solid Tumors v1.0, best overall response was characterized as confirmed complete response (CR) defined as disappearance of all target lesions, confirmed partial response (PR) defined as ≥30% decrease from baseline, stable disease (SD) defined as neither progressive disease (PD) nor PR, and PD defined as ≥20% increase from smallest sum of longest diameter recorded since treatment started. Objective response rate (ORR) was defined as CR + PR. If there is no tumor assessment after the first dose of study drug, the best overall response is classified as Inevaluable.
