A Study of Ocular Toxicity Evaluation and Mitigation During Treatment With Mirvetuximab Soravtansine in Participants With Recurrent Ovarian Cancer With High Folate Receptor-Alpha Expression
Trial Status: active
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.
Inclusion Criteria
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.
Exclusion Criteria
Participants with borderline ovarian tumor or non-epithelial histology or mixed histology including borderline or non-epithelial histology will be excluded.
PROC participants with primary platinum-refractory disease, defined as disease that did not respond to (complete response [CR] or partial response [PR]) or progressed within ≤ 3 months of the last dose of first line platinum-containing chemotherapy.
Participants with > Grade 1 peripheral neuropathy per National Cancer Institute-Common Terminology Criteria for Adverse Events version 5.0 (NCI-CTCAE v5.0).
Participants with significant active or chronic corneal disorders (for example, corneal dystrophies, degenerations, limbal stem cell deficiency), history of corneal transplantation, significant ocular inflammatory conditions (for example, active or recurrent uveitis), or other active ocular conditions requiring ongoing treatment/monitoring, such as uncontrolled glaucoma, active diabetic retinopathy with macular edema, macular degeneration requiring treatment ≤ 90 days before first dose, presence of papilledema, best corrected visual acuity (BCVA) worse than 20/70 in either eye, or monocular vision.
Participants receiving corticosteroid or vasoconstricting eyedrops at baseline or within 5 weeks of Cycle 1 Day 1.
Participants who received prior treatment with MIRV or other FRα-targeting agents. Note: Other protocol-defined inclusion and exclusion criteria may apply.
