Clinical Trial Summary

This study is being done to see how well two drugs (enfortumab vedotin and pembrolizumab) work together to treat patients with urothelial cancer. The study will compare these drugs to other drugs that are usually used to treat this cancer (standard of care). The patients in this study will have cancer that has spread from their urinary system to other parts of their body.

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. This study is being conducted to evaluate the combination of enfortumab vedotin + pembrolizumab versus standard of care gemcitabine + platinum-containing chemotherapy, in subjects with previously untreated locally advanced or metastatic urothelial cancer. Enfortumab vedotin may be administered for an unlimited number of cycles until a protocol defined reason for study discontinuation occurs. Pembrolizumab may be administered for a maximum of 35 cycles or a protocol-defined reason for study discontinuation occurs, whichever is first. Cisplatin or carboplatin plus gemcitabine may be administered for a maximum of 6 cycles or a protocol-defined reason for study discontinuation occurs, whichever is first.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Duration of progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 by blinded independent central review (BICR) (Arms A and B only, global population)	Defined as the time from randomization to first documentation of disease progression per RECIST v1.1 by BICR, or to death due to any cause, whichever comes first.	Up to approximately 5 years
Primary	Duration of Overall survival (OS) (Arms A and B only, global population)	OS is defined as the time from date of randomization to date of death due to any cause.	Up to approximately 5 years
Secondary	Objective response rate (ORR) per RECIST v1.1 by BICR (Arms A and B only)	Defined as the proportion of subjects with confirmed CR or PR according to RECIST v1.1	Up to approximately 5 years
Secondary	Time to pain progression (TTPP) (Arms A and B only)	Defined as the time from randomization to the first date a subject experiences a pain progression. Pain progression is defined as either an increase of 2 or more points from baseline on question 3 of the Brief Pain Inventory - Short Form (BPI-SF) or initiation of new opioid pain medication.	Up to approximately 5 years
Secondary	Mean change from baseline in worst pain at Week 26 (Arms A and B only)	Using the BPI-SF question 3, mean change from baseline in worst pain will be calculated for each postbaseline assessment timepoint for Arm A and Arm B.	Up to approximately 6 months

Secondary	Change from baseline in patient reported outcome assessment measured by the EuroQOL Five Dimensions Questionnaire 5L (EQ-5D-5L)	The EQ-5D-5L is a standardized instrument developed by the EuroQol Group for use as a generic, preference-based measure of health outcomes. The EQ-5D-5L is a 5-item self-reported measure of functioning and wellbeing, which assesses 5 dimensions of health, including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension comprises 5 levels (no problems, slight problems, moderate problems, severe problems, extreme problems). A unique EQ-5D-5L health state is defined by combining 1 level from each of the 5 dimensions. This questionnaire also records the respondent's self-rated health status on a vertical graduated (0 = the worst health a participant can imagine to 100 = the best health a participant can imagine) visual analogue scale.	Up to approximately 5 years

Up to approximately 5 years
Secondary	Change from baseline in patient reported outcome assessment measured by European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30)	EORTC-QLQ-C30 is a cancer-specific 30-item questionnaire. Participants rate items on a four-point scale, with 1 as "not at all" and 4 as "very much." A change of 5 - 10 points is considered a small change. A change of 10 - 20 points is considered a moderate change.	Up to approximately 5 years

Participants rate items on a four-point scale, with 1 as "not at all" and 4 as "very much." A change of 5 - 10 points is considered a small change. A change of 10 - 20 points is considered a moderate change.	Up to approximately 5 years
Secondary	Incidence of adverse events (AEs)	Descriptive statistics will be used to summarize results	Up to approximately 5 years
