FDA Approval Insights: Mirvetuximab Soravtansine in Platinum-Resistant Ovarian Cancer

Welcome to OncLive On Air^®! I’m your host today, Ashling Wahner.

OncLive On Air^® is a podcast from OncLive^®, which provides oncology professionals with the resources and information they need to provide the best patient care. In both digital and print formats, OncLive^® covers every angle of oncology practice, from new technology to treatment advances to important regulatory decisions.

In today’s episode, we had the pleasure of speaking with Ursula A. Matulonis, MD, chief of the Division of Gynecologic Oncology and the Brock-Wilson Family Chair at Dana-Farber Cancer Institute, as well as a professor of medicine at Harvard Medical School. Dr Matulonis joined us to talk about the FDA approval of mirvetuximab soravtansine-gynx (Elahere) in patients with folate receptor α (Frα)–positive, platinum-resistant ovarian cancer.

On November 14, 2022, the FDA gave accelerated approval to mirvetuximab soravtansine in adults with Frα-positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer who have received between 1 and 3 prior systemic treatments. The approval was supported by findings from the phase 3 SORAYA trial (NCT04296890), which showed an objective response rate of 31.7% and a duration of response of 6.9 months in those who received the agent.

In our exclusive interview, Dr Matulonis discussed the significance of this approval, key efficacy and safety data from SORAYA, and how further research, including the ongoing phase 3 MIRASOL trial (NCT04209855), can continue the momentum behind finding effective treatments for patients with ovarian cancer.
