About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
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).
Systemic antineoplastic therapy ≥ 5 half-lives or 4 weeks (whichever is shorter) before first dose of MIRV;
Disqualifiers
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.

Treatments tested in this trial
Mirvetuximab Soravtansine
DrugMirvetuximab soravtansine is an antibody drug conjugate designed to target folate receptor α (FRα). It consists of the humanized anti-FRα monoclonal antibody (mAb) M9346A attached via a cleavable disulfide linker to the cytotoxic maytansinoid, DM4.
Lubricating Eye Drops
DrugLubricating artificial tears should be administered at least 15 minutes after corticosteroid or brimonidine eye drop administration.
Prednisolone acetate ophthalmic suspension 1% eye drops
DrugSelf-administration of prednisolone acetate ophthalmic suspension 1% eye drops as prescribed by the treating physician.
Brimonidine tartrate ophthalmic solution eye drops
DrugSelf-administration of brimonidine tartrate ophthalmic solution eye drops as prescribed by the treating physician.
