What was measured

Duration of Response was defined as the time from date of first response (Complete Response \[CR: disappearance of all clinical and radiological evidence of tumor (both target and non-target).\] or Partial Response \[PR: at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum, no unequivocal progression of existing non-target lesions, and no appearance of new lesions.\]) to the date when Progressive Disease (PD: at least a 20% increase in the sum of diameters of target lesions taking as reference the smallest sum on study or unequivocal progression of existing non-target lesions, or appearance of new lesions.) is first documented, or to the date of death, whichever occurs first, according to RECIST v1.1. Subjects still having CR or PR and have not died at the time of analysis were censored at their last date of tumor evaluation. Duration of response defined for responders only, i.e CR or PR. Results are based on central evaluation.
