Brief description of study

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 neoadjuvant carboplatin and mirvetuximab soravtansine in participants with folate receptor alpha (FRα) -expressing advanced-stage serous epithelial ovarian, fallopian tube or primary peritoneal cancer (EOC).

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). This is a single arm study in adult participants with advanced-stage Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) III-IV FRα-expressing serous EOC. Around 140 participants will be enrolled in the study at approximately 80 sites in the United States.

Participants will receive intravenous infusion of MIRV in combination with carboplatin on day 1 of each cycle, every 21 days for up to 6 - 9 Cycles. The total study duration will be approximately 3 years .

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.

Eligibility of study

You may be eligible for this study if you meet the following criteria:

  • Conditions: Epithelial Ovarian Cancer, Fallopian Tube Cancer, Primary Peritoneal Cancer, Neoadjuvant
  • Age: 18 years or above
  • Gender: Female

Inclusion Criteria:

  • Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2.
  • Be judged by the investigator and/or treating physician to be an appropriate candidate to receive neoadjuvant chemotherapy.
  • Diagnosis of biopsy-confirmed high-grade, serous epithelial ovarian, fallopian tube or primary peritoneal cancer.
  • Participant meets the following disease criteria:
    • Stage III or IV disease by the Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) staging system, and
    • Folate Receptor Alpha (FRα) expression positivity as defined by immunohistochemical staining of >= 75% of viable tumor cells with moderate >= 2+ membrane staining by the Ventana Folate Receptor Alpha (VENTANA FOLR1) assay, FOLR1 Eligibility Testing - Ventana FOLR1 (FOLR1-2.1) RxDx - Commercial or Central, and
    • Measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 criteria.

Exclusion Criteria:

  • Endometrioid, clear cell, mucinous, or sarcomatous tumor histology; mixed tumors containing any of the above histologies; or low-grade/borderline ovarian tumor.
  • Previous clinical diagnosis of noninfectious interstitial lung disease, including noninfectious pneumonitis.
  • Previously treated with anticancer therapy including chemotherapy, radiation therapy, immunotherapy, or biologic agent for current cancer, with the exception of one cycle of single agent carboplatin
  • Participants with the following ocular history and/or concurrent disorders:
    • History of corneal transplantation;
    • Undergoing active postoperative management for refractive surgery, cataract surgery, corneal cross-linking, or corneal complications of surgery;
    • Confluent superficial punctate keratopathy (SPK) not expected to resolve to non-confluence or better within the screening window with standard of care (SOC) intervention;
    • Active or chronic clinically significant (>= Grade 3) corneal dystrophy (e.g., Fuchs dystrophy);
    • Active ocular conditions requiring ongoing treatment/monitoring, such as glaucoma, which is not adequately controlled with medication or surgery, wet age-related macular degeneration requiring intravitreal injections, active diabetic retinopathy with macular edema, macular degeneration, presence of papilledema or an ocular condition with high risk of retinal detachment;
    • Monocular vision with visual acuity in the worse eye, worse than 20/200 or visual fields less than 20 degrees (i.e., functional blindness in at least one eye).
  • History of other malignancy within 3 years prior to signing study consent. -- Note:

    Participants with tumors with a negligible risk for metastasis or death (e.g., adequately controlled basal-cell carcinoma or squamous-cell carcinoma of the skin, or carcinoma in situ of the cervix or breast) are eligible.

The purpose of this study is to assess the safety and effectiveness of a combination of investigational medication and another drug in treating advanced-stage ovarian, fallopian tube, or primary peritoneal cancer. This study targets cancers that express a specific protein called folate receptor alpha (FRα). This protein is found on the surface of cancer cells, and the investigational medication is designed to attach to these cells and deliver a drug that kills them.

Participants in this study will receive the investigational medication along with another drug through an intravenous infusion. This process will occur every 21 days, and each cycle of treatment can last from 6 to 9 cycles. During the study, participants will have regular hospital or clinic visits, which may include medical assessments, blood tests, and scans to monitor their health and the effectiveness of the treatment.

  • Who can participate: Adults with advanced-stage serous epithelial ovarian, fallopian tube, or primary peritoneal cancer that express the folate receptor alpha protein can participate, with key eligibility including an ECOG performance status of 0, 1, or 2 and measurable disease by specific criteria.
  • Study details: Participants will receive the investigational medication through an intravenous infusion in combination with another drug every 21 days for several cycles, attending regular medical assessments.
  • Study timelines: The study will last approximately 3 years.
