Japan's Ministry of Health, Labour and Welfare Approves PADCEV™ (enfortumab vedotin) with KEYTRUDA® (pembrolizumab) for First-Line Treatment of Radically Unresectable Urothelial Carcinoma
Astellas Pharma Inc. announced that Japan's Ministry of Health, Labour and Welfare (MHLW) has approved PADCEV™ (enfortumab vedotin) with KEYTRUDA® (pembrolizumab) as a combination therapy for the first-line treatment of adult patients with radically unresectable urothelial carcinoma. This approval is based on the EV-302 clinical trial, which showed significant improvements in overall survival and progression-free survival compared to platinum-containing chemotherapy.
Key findings from the EV-302 trial include:
- Median overall survival: 31.5 months for the combination therapy vs. 16.1 months for chemotherapy
- 53% reduction in risk of death
- Median progression-free survival: 12.5 months for the combination therapy vs. 6.3 months for chemotherapy
- 55% reduction in risk of cancer progression or death
This approval offers an alternative to platinum-containing chemotherapy, the current standard of care for first-line treatment of radically unresectable urothelial cancer in Japan.

The approval by the MHLW was supported by results from the Phase 3 EV-302 clinical trial (also known as KEYNOTE-A39) which explored the efficacy and safety of enfortumab vedotin in combination with pembrolizumab in patients with previously untreated locally advanced or metastatic urothelial cancer (la/mUC). Results showed that the treatment combination resulted in a median overall survival of 31.5 months (

About EV-302
The EV-302 trial is an open-label, randomized, controlled Phase 3 study, evaluating enfortumab vedotin in combination with pembrolizumab versus platinum-containing chemotherapy in patients with previously untreated la/mUC. The study enrolled 886 patients with previously untreated la/mUC who were eligible for cisplatin- or carboplatin-containing chemotherapy regardless of PD-L1 status. Patients were randomized to receive either enfortumab vedotin in combination with pembrolizumab or platinum-containing chemotherapy. The dual primary endpoints of this trial are OS and PFS per RECIST v1.1 by blinded independent central review (BICR). Select secondary endpoints include ORR per RECIST v1.1 by BICR, DOR per RECIST v1.1 by BICR, and safety.1
The EV-302 trial is part of an extensive clinical program evaluating this combination in multiple stages of urothelial cancer and other solid tumors. Findings from EV-302 were presented at the 2023 European Society for Medical Oncology (ESMO) Congress and published in the New England Journal of Medicine.1

About PADCEV™ (enfortumab vedotin [genetical recombination])
PADCEV (enfortumab vedotin [genetical recombination]) is a first-in-class antibody-drug conjugate (ADC) that is directed against Nectin-4, a protein located on the surface of cells and highly expressed in bladder cancer.11,12 Non-clinical data suggest the anticancer activity of enfortumab vedotin is due to its binding to Nectin-4-expressing cells, followed by the internalization and release of the anti-tumor agent monomethyl auristatin E (MMAE) into the cell, which result in the cell not reproducing (cell cycle arrest) and in programmed cell death (apoptosis).11

Ongoing Investigational Trials
EV-302 (NCT04223856) is an open-label, randomized, controlled Phase 3 trial, evaluating enfortumab vedotin in combination with pembrolizumab versus platinum-containing chemotherapy in patients with previously untreated locally advanced or metastatic urothelial cancer (la/mUC) who were eligible for cisplatin- or carboplatin-containing chemotherapy regardless of PD-L1 status.
EV-103 (NCT03288545) is an ongoing, multi-cohort, open-label, multicenter Phase 1b/2 trial investigating enfortumab vedotin alone or in combination with pembrolizumab and/or chemotherapy in first- or second-line settings in patients with la/mUC and in patients with muscle-invasive bladder cancer (MIBC).
Enfortumab vedotin in combination with pembrolizumab is being investigated in an extensive program in multiple stages of urothelial cancer, including two Phase 3 clinical trials in MIBC in EV-304 (NCT04700124, also known as KEYNOTE-B15) and EV-303 (NCT03924895, also known as KEYNOTE-905). The use of enfortumab vedotin in combination with pembrolizumab in second-line urothelial cancer and MIBC has not been proven safe or effective.
EV-203 (NCT04995419) is a Phase 2, multicenter, single-arm bridging trial in
EV-104 (NCT05014139) is a Phase 1 trial exploring enfortumab vedotin in patients with non-muscle invasive bladder cancer (NMIBC). The trial will be conducted in two-parts, assessing dose escalation and dose expansion with enfortumab vedotin when administered intravesically as a monotherapy.
EV-202 (NCT04225117) is an ongoing, multi-cohort, open-label, multicenter Phase 2 trial investigating enfortumab vedotin alone in patients with previously treated advanced solid tumors. This trial also has a cohort that is investigating enfortumab vedotin in combination with pembrolizumab in patients with previously untreated recurrent / metastatic head and neck squamous cell carcinoma.
