What was measured

ORR was defined as the proportion of patients with confirmed complete response (CR) + confirmed partial response (PR) based on independent radiologic review using modified RECIST (mRECIST) criteria as best overall response. Per mRECIST 1.1 criteria, complete response is defined as disappearance of all target lesions; partial response is defined as \>=30% decrease in the sum of the longest diameter of target lesions.

Analysis population: All patient (AP) Intent to Treat (ITT) Population is defined as all patients who are randomized. Patients in this population will be analyzed according to the treatment they were scheduled to receive.

Groups in this outcome
