What was measured

Objective response rate (ORR) is defined as the proportion of participants having a confirmed Best Overall Response (BOR) of CR or PR by central reader using RECIST v1.1 criteria. Responses obtained up until progression, or last evaluable assessment in the absence of progression, will be included in the assessment of ORR. However, any responses, which occurred after a new anticancer therapy was received, will not be included. ORR is presented by percentages of responders.
