Treatment

  • Mirvetuximab is given as monotherapy
  • Mirvetuximab is administered intravenously.

 

Treatment duration

The treatment can continue until disease progression, unacceptable toxicity or withdrawal of consent.

Eligibility

Main inclusion criteria:

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

 

Main exclusion criteria:

  • 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

Criteria might change during the course of the study due to amendments.
