A Randomized Phase 2 Study of Ocular Toxicity Evaluation and Mitigation During Treatment With Mirvetuximab Soravtansine in Patients With Recurrent Ovarian Cancer With High Folate Receptor-Alpha Expression
The purpose of this study is to evaluate the incidence rate and severity of prespecified mirvetuximab soravtansine (MIRV)-related ocular treatment-emergent adverse events (TEAEs) and assess prophylaxis strategies in all participants (symptomatic and asymptomatic) undergoing prospective ophthalmic evaluation with recurrent ovarian cancer (participants with either platinum-sensitive ovarian cancer \[PSOC\] or platinum-resistant ovarian cancer \[PROC\]) with high folate receptor alpha (FRα) expression.
• Participants must have a confirmed diagnosis of epithelial ovarian, fallopian tube, and primary peritoneal cancer (EOC) with high FRα expression.
• Participant's tumor must be FRα positive (FRα high) as defined by either the VENTANA FOLR1 (FOLR-2.1) IUO Assay, or the VENTANA FOLR1 ( FOLR1-2.1) RxDx Assay (hereafter collectively termed VENTANA FOLR1 Assay) (≥ 75% cells exhibit ≥ 2+ membrane staining intensity).
• Participants with known breast cancer susceptibility gene (BRCA) mutations (tumor or germline) must have received poly (ADP-ribose) polymerase inhibitors (PARPi).
• Participants must have completed prior therapy within the specified times below:
‣ Systemic antineoplastic therapy ≥ 5 half-lives or 4 weeks (whichever is shorter) before first dose of MIRV;
⁃ Focal radiation completed ≥ 2 weeks before the first dose of MIRV.
• Participants must have stabilized or recovered (Grade 1 or baseline) from all prior therapy-related toxicities (except alopecia).
• Women of childbearing potential (WOCBP) must agree to use highly effective contraceptive method(s) while on MIRV and for ≥ 7 months after the last dose; and must have a negative pregnancy test ≤ 4 days before the first dose of MIRV.
