What was measured

DOR: time from the date of the first CR/PR (whichever is first recorded) that was subsequently confirmed as assessed by investigator to the date of documented PD or death due to any cause whichever occurred first. If a participant has neither progressed nor died, the participant was censored at the date of last RA or at the date of first CR/PR if no subsequent post-baseline RA was available. Participants who received any further ACT for the disease before radiological progression were censored at the date of the last RA before the ACT started. In addition, participants who had PD/death after \>= 2 missed RAs were censored at the last RA prior to the 2 or more missed RAs. Kaplan-Meier estimates was used. Median time of follow up for DOR was based on data cut-off and is same as median follow-up time for OS. CR/PR and PD were defined in ORR and PFS1 endpoints, respectively.

Analysis population: RES population with available data.

Groups in this outcome

Enfortumab Vedotin 1.25 mg/kg

Participants received 1.25 mg/kg of body weight enfortumab vedotin by IV infusion over approximately 30 minutes on days 1, 8 and 15 of every 28-day cycle. Participants received study treatment until radiological disease progression as determined per investigator assessment or other discontinuation criteria were met or upon study termination, or study completion, whichever occurred first.

Chemotherapy

Participants received either 75 mg/m\^2 docetaxel by IV infusion over approximately 1 hour or 320 mg/m\^2 vinflunine by IV infusion over approximately 20 minutes or 175 mg/m\^2 paclitaxel by IV infusion over approximately 3 hours on day 1 of every 21-day cycle. Participants received study treatment until radiological disease progression as determined per investigator assessment or other discontinuation criteria were met or upon study termination, or study completion, whichever occurred first.
