What was measured

The time from start of study treatment to first documentation of objective tumor progression (PD per RECIST 1.1), or to death due to any cause, whichever comes first. 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.

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.
