Clinical summary

Summary

Cancer happens when cells in the body grow and spread in an uncontrolled way. 

This study is testing a medicine called mirvetuximab soravtansine (also called MIRV) in people with certain types of ovarian cancer that have come back or stopped responding to treatment with platinum-based chemotherapy.

MIRV is an investigational targeted treatment known as an antibody-drug conjugate. This means it is designed to find cancer cells using a specific marker (FRα) and deliver a chemotherapy drug directly into those cells to destroy them.

Who can take part?
This trial is for people with:

  • advanced ovarian, fallopian tube, or primary peritoneal cancer
  • cancer that has stopped responding to platinum treatment
  • tumours that have a high level of a protein called folate receptor alpha (FRα)

How the study works
There are two parts (cohorts) in this study.

  1. Randomised phase 2 group
    • Participants are randomly placed (by chance) into 1 of 2 groups
    • Both groups receive MIRV, but on different schedules:
      • Once every 3 weeks, or
      • Twice every 4 weeks
  2. Liver function group
    • This group is for people with moderate liver problems
    • It aims to find the safest starting dose of MIRV for these patients

What does taking part involve?
If you join this trial, you will have regular visits to a hospital or clinic, receive the study treatment (MIRV), and have check-ups such as blood tests, scans, and other assessments.

Taking part may involve more visits and tests than standard care, which could increase the time and effort required.

The study will enrol around 110 people around the world, and is expected to run for about 2 years. 

 

Conditions

This trial is treating people with high-grade serous epithelial ovarian cancer, primary peritoneal cancer, or fallopian tube cancer who have progressed on prior platinum-based therapy

Eligibility

Inclusion

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

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.

Inclusion

  • You have had treatment, but your cancer has come back (relapsed or recurrent).
  • Your cancer has spread to other parts of the body (metastatic) or has grown into nearby parts of the body (locally advanced).
  • You have had treatment but your cancer has gotten worse or has not responded to the treatment you have been given.
  • You have had a certain type of treatment or surgical procedure.

Exclusion

  • You have certain types of non-cancer medical conditions.
  • You have had certain treatments, surgical procedures or drugs.
