Highlights:

• Mirvetuximab soravtansine (MIRV) is a first-in-class antibody-drug conjugate comprising an FRα-binding antibody, cleavable linker, and maytansinoid DM4, a potent tubulin-targeting agent
• Early clinical data suggested efficacy in recurrent platinum-resistant ovarian cancer (PROC) prompting a larger trial to confirm both safety and efficacy in patients with PROC
• In this SORAYA trial MIRV demonstrated clinically meaningful antitumor activity in patients with FRα-high platinum-resistant ovarian cancer with an ORR: 32.4% and a median DOR: 6.9 months
  • Remarkably the median OS was 15 months; 37% patients alive at 24 months
• Efficacy of MIRV was further evaluated with respect to when it was administered (as first treatment for PROC) and in patients receiving prior bevacizumab. An ORR of 34.8% was documented in the formers, and 31.5% in the latter.
• The ocular toxicity was new for many treating physicians when the drug first became available. However with mitigating strategies as used in the study the events were predictable, low-grade, and rarely (n=1 patient) led to treatment discontinuation
• Now with MIRASOL confirming these data and demonstrating efficacy over standard of care for response, PFS, and unprecedently, OS, the agent is a staple of contemporary management.
