What was measured

Percentage of participants with CR, PR, or stable disease (SD) at Week 16 visit. CR is defined as disappearance of all target lesions and non-target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR is defined as a \>=30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters. PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 0.5 cm. The appearance of one or more new lesions is also considered progression. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

Analysis population: Full analysis set: includes all enrolled participants who received at least one dose of enfortumab vedotin.

Groups in this outcome

Enfortumab Vedotin - Cohort 1

Participants in Cohort 1 had received prior treatment with platinum-containing chemotherapy. Enfortumab vedotin, at a dose of 1.25 mg/kg, was administered to participants as an IV infusion over approximately 30 minutes on Days 1, 8, and 15 of each 28-day cycle.

Enfortumab Vedotin - Cohort 2

Participants in Cohort 2 had received no platinum-containing chemotherapy were ineligible for treatment with cisplatin at the time of enrollment. Enfortumab vedotin, at a dose of 1.25 mg/kg, was administered to participants as an IV infusion over approximately 30 minutes on Days 1, 8, and 15 of each 28-day cycle.
