Abstrakt: | Objective: The single-arm, phase II SORAYA trial (NCT04296890) of mirvetuximab soravtansine-gynx in folate receptor alpha (FRα)-high platinum-resistant ovarian cancer (n=105 (efficacy-evaluable)) met its primary endpoint with an objective response rate of 32.4% (95% CI, 23.6 to 42.2). Here we report final SORAYA trial results for overall survival and post hoc objective response rates in subgroups by sequence and number of prior therapies. Methods: Eligible patients had high-grade serous platinum-resistant ovarian cancer with high FRα expression and one to three prior therapies (prior bevacizumab required). Enrolled participants received 6 mg/kg mirvetuximab soravtansine-gynx adjusted ideal body weight intravenously once every 3 weeks until progressive disease, unacceptable toxicity, withdrawal of consent, or death. Final overall survival and post hoc objective response rates were assessed in efficacy-evaluable participants. The safety population included all patients who received ≥1 dose of mirvetuximab soravtansine-gynx. Results: At data cut-off (December 22, 2022; n=105), final median overall survival was 15.0 months (95% CI, 11.5 to 18.7). Median overall survival in participants with one to two prior therapy lines was 18.7 months (95% CI, 13.8 to not estimable (NE)) and 11.6 months (95% CI, 7.1 to 16.7) with three prior therapy lines. Median overall survival was 15.0 months (95% CI, 11.5 to NE) in participants with prior poly (ADP-ribose) polymerase inhibitor (PARPi) treatment versus 14.0 months (95% CI, 7.1 to NE) in those without. Objective response rate (data cut-off: November 17, 2021) differed among participants who received mirvetuximab soravtansine-gynx as their first treatment in the platinum-resistant setting (34.8%; 95% CI, 23.5 to 47.6) versus a different first treatment (28.2%; 95% CI, 15.0 to 44.9) or had received prior bevacizumab in a platinum-sensitive (34.0%; 95% CI, 24.6 to 44.5) versus platinum-resistant setting (17.6%; 95% CI, 3.8 to 43.4). No new safety signals were observed. Conclusion: These results support the clinically meaningful efficacy of mirvetuximab soravtansine-gynx in FRα-expressing platinum-resistant ovarian cancer, irrespective of prior treatment or sequence.
