ORR is a percentage of participants determined by the number of participants with a best overall response (BOR) of complete response (CR) or partial response (PR) divided by the number of measurable participants with target lesion at baseline. BOR is defined as the best response designation as determined by the BICR, recorded between the date of randomization and the date of objectively documented progression (per RECIST 1.1 as determined by the BICR) or the date of subsequent anti-cancer therapy, whichever occurs first. CR is defined as the disappearance of all target lesions. PR is define as at 30% decrease in the sum of diameters of target lesions.
