Bladder Cancer Clinical Trial
A Study to Evaluate Enfortumab Vedotin Versus (vs) Chemotherapy in Subjects With Previously Treated Locally Advanced or Metastatic Urothelial Cancer (EV-301)
Summary
The purpose of this study was to compare the overall survival (OS) of participants with locally advanced or metastatic urothelial cancer treated with enfortumab vedotin (EV) to the OS of participants treated with chemotherapy.
This study compared progression-free survival on study therapy (PFS1); the overall response rate (ORR) and the disease control rate (DCR) per Response Evaluation Criteria in Solid Tumors (RECIST) V1.1 of participants treated with EV to participants treated with chemotherapy.
In addition, this study evaluated the duration of response (DOR) per RECIST V1.1 of EV and chemotherapy and assessed the safety and tolerability of EV, as well as, the quality of life (QOL) and Patient Reported Outcomes (PRO) parameters.
Full Description
Japan PMDA has approved enfortumab vedotin (Padcev) for the treatment of advanced urothelial cancer. The study will continue as a post marketing study in Japan.
Participants considered an adult according to local regulation at the time of obtaining informed consent participated in the study.
Eligibility Criteria
Inclusion Criteria:
Subject is legally an adult according to local regulation at the time of signing informed consent.

Subject has radiologically documented metastatic or locally advanced disease at baseline.
An archival tumor tissue sample should be available for submission to central laboratory prior to study treatment.

Female subject must agree not to breastfeed or donate ova starting at screening and throughout the study period, and for at least 6 months after the final study drug administration.
A sexually active male subject with female partner(s) who is of childbearing potential is eligible if:
Agrees to use a male condom starting at screening and continue throughout the study treatment and for at least 6 months after final study drug administration. If the male subject has not had a vasectomy or is not sterile as defined below the subjects female partner(s) is utilizing 1 form of highly effective birth control per locally accepted standards starting at screening and continue throughout study treatment and for at least 6 months after the male subject receives final study drug administration.
Male subject must not donate sperm starting at screening and throughout the study period, and for at least 6 months after the final study drug administration.
Male subject with a pregnant or breastfeeding partner(s) must agree to abstinence or use a condom for the duration of the pregnancy or time partner is breastfeeding throughout the study period and for at least 6 months after the final study drug administration.
Subject agrees not to participate in another interventional study while on treatment in present study.
Inclusion Criteria for COE:
Subject is eligible for the COE if they continue to meet all inclusion criteria from the main protocol in addition to the following when the patient is evaluated for eligibility to participate in the COE portion of the study:
Institutional review board (IRB)/ independent ethics committee (IEC) approved written COE informed consent and privacy language as per national regulations (e.g., health insurance portability and accountability act [HIPAA] Authorization for US sites) must be obtained from the subject prior to any study-related procedures (including withdrawal of prohibited medication, if applicable).
Subject was randomized to Arm B and is either currently on study treatment or has discontinued study treatment due to intolerance, AE or progression of disease and has not started a new systemic anticancer treatment.
Exclusion Criteria:
Subject has preexisting sensory or motor neuropathy Grade ≥ 2.
