The potential approval for the combination regimen could revolutionise the standard of care for first-line la/mUC, offering an alternative to the platinum-containing chemotherapy that is currently administered.
The sBLA is based on the data from the randomised, open-label, controlled Phase III EV-302 clinical trial, also known as KEYNOTE-A39.
This study compared enfortumab vedotin in combination with pembrolizumab to platinum-containing chemotherapy in 886 patients.
Overall survival (OS) and progression-free survival (PFS) were the trial’s primary outcomes.
Secondary endpoints included objective response rate (ORR), duration of response (DOR), and safety profiles.
The results demonstrated that the combination of enfortumab vedotin with pembrolizumab significantly improved OS and PFS, with meaningful clinical outcomes when compared to the standard chemotherapy regimen.
The safety profile of the combination therapy was in line with prior reports without any new safety concerns identified.
In addition to the CDE’s review, the NMPA is considering enfortumab vedotin as a treatment option for la/mUC patients who have previously undergone therapy with a PD-1/L1 inhibitorPD-1/L1 inhibitor and platinum-based chemotherapy.
Parallelly, the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) and Japan’s Ministry of Health, Labour and Welfare (MHLW) are also reviewing the combination regimen.
“The CDE’s acceptance of our sBLA for enfortumab vedotin and pembrolizumab brings us one step closer to delivering a much-needed, innovative new treatment option for this patient population.”
