Brief Summary

Cancer is a condition where cells in a specific part of body grow and reproduce uncontrollably. The purpose of this study is to assess the safety and efficacy of for Mirvetuximab Soravtansine in participants with platinum-resistant advanced high-grade epithelial ovarian, primary peritoneal, or fallopian tube cancer (platinum-resistant ovarian cancer) (PROC) whose tumors express a high level of folate receptor alpha (FRα).

Mirvetuximab Soravtansine (MIRV) is an investigational antibody drug conjugate designed to selectively kill cancer cells. The antibody (protein) part of MIRV targets tumors by delivering a cell-killing drug to cancer cells carrying a protein called folate receptor alpha (FRα). There are 2 cohorts in this study, the Randomized Phase 2 Cohort and the Hepatic Impairment Cohort. In the Randomized Phase 2 Cohort, participants are placed in 1 of 2 groups, called treatment arms. Each treatment arm receives MIRV on a different schedule (on day 1 every 21 days or on days 1 and 15 every 28 days). The Hepatic Impairment Cohort is designed to determine the starting dose of MIRV in patients with moderately abnormal liver function. Around 110 participants will be enrolled in the study at approximately 75 sites worldwide.

The total study duration will be approximately 24 months.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic and may require frequent medical assessments, blood tests, and scans.

Inclusion Criteria

Both Cohorts

  • Participants with a confirmed diagnosis of high-grade serous epithelial ovarian cancer (EOC), primary peritoneal cancer, or fallopian tube cancer.

  • Participants with platinum-resistant disease:

    • Participants with 1 prior line of platinum-based therapy who have received ≥ 4 cycles of platinum and had a response (complete response (CR) or partial response (PR)) followed by radiological progressive disease (PD) between > 3 months and ≤ 6 months after the date of the last dose of platinum.

    • Participants with 2 or 3 prior lines of platinum-based therapy who had radiological PD

      • 6 months after the date of the last dose of platinum.
  • Participants with progression diagnosed radiographically on or after their most recent line of therapy.

  • Participants with an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 or 1.

  • Participants with ≥ 1 lesion that meets the definition of measurable disease by RECIST v1.1 (radiologically measured by the investigator).

  • Participants with a tumor that is positive for folate receptor alpha (FRα) expression as determined by the Ventana folate receptor 1 (FOLR1) assay (≥ 75% of tumor staining at 2+ intensity).

Exclusion Criteria

Both Cohorts

  • Participants with endometrioid, clear cell, mucinous, or sarcomatous histology; mixed tumors containing any of the above histologies; or low-grade or borderline ovarian tumor.
  • Participants with primary platinum-refractory disease, defined as disease that did not respond (complete response (CR) or partial response (PR)) or that progressed radiographically within 3 months of the last dose of first-line platinum-containing chemotherapy.
  • Participants with serious concurrent illness or clinically relevant active infection as outlined in the protocol
  • Participants with a history of hemorrhagic or ischemic stroke within 6 months prior to randomization.
