Dr. Gupta on 4-year data for enfortumab vedotin/pembrolizumab in urothelial carcinoma

Video

Shilpa Gupta, MD, discusses long-term outcomes of the EV-103 trial, which explored the first-line combination of enfortumab vedotin and pembrolizumab in cisplatin-ineligible patients with locally advanced or metastatic urothelial carcinoma.

Shilpa Gupta, MD, director of genitourinary medical oncology at Taussig Cancer Institute and co-leader of the Genitourinary Oncology Program at Cleveland Clinic, discusses the abstract, “Study EV-103 dose escalation/cohort A: Long-term outcome of enfortumab vedotin + pembrolizumab in first-line (1L) cisplatin-ineligible locally advanced or metastatic urothelial carcinoma (la/mUC) with nearly 4 years of follow-up,” which she presented at the 2023 ASCO Annual Meeting (4505).

Transcript

This is the dose-escalation and cohort A populations of the EV-103 phase 1b study evaluating enfortumab vedotin and pembrolizumab in cisplatin-ineligible patients with locally advanced or metastatic urothelial cancer. Also, this for treatment-naive patients. Patients received enfortumab vedotin on days 1 and 8 and pembrolizumab every 21 days. The primary end point was safety and secondary end points included overall response rate, overall survival, and progression-free survival.

Previous results from this study have already led to the FDA approval of the combination in the setting. And now we are reporting 4-year follow-up data showing an objective response rate of around 73.3% by BICR which is highly concurrent with the investigator-assessed responses which were reported earlier. The median overall survival is exceeding two years at 26.1 months and the tail of the curve is still holding strong. The median progression-free survival is 12.7 months. Complete responses were 16%.

We did not see any new safety signals of the combination and I think these findings really show the durability of this combination and how effective it is. The ongoing phase 3 EV-302 study has completed accrual and is looking at the combination against chemotherapy will further lead to our understanding of whether it can surpass the chemotherapy.
