About this study

Official title: A Phase I Dose-Escalation Safety and Tolerability Study of MirvetuximabSoravtansine (IMGN853) and Gemcitabine in Patients With FRa-positive Recurrent Ovarian, Primary Peritoneal, Fallopian Tube, Endometrial Cancer, or Triple Negative Breast Cancer (TNBC)

This phase I trial studies the side effects and best dose of mirvetuximab soravtansine and gemcitabine hydrochloride in treating patients with folate receptor (FR) alpha-positive ovarian, primary peritoneal, fallopian tube, endometrial, or triple negative breast cancer that has come back. Mirvetuximab soravtansine is a monoclonal antibody, called mirvetuximab, linked to a chemotherapy drug called DM4. Mirvetuximab attaches to FOLR1 positive cancer cells in a targeted way and delivers DM4 to kill them. Drugs used in the chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving mirvetuximab soravtansine and gemcitabine may work better in treating patients with FRalpha-positive ovarian, primary peritoneal, fallopian tube, endometrial, or triple negative breast cancer.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To determine the maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of gemcitabine hydrochloride (gemcitabine) when given in combination with mirvetuximab soravtansine (IMGN853) to patients with FRalpha-positive recurrent ovarian, primary peritoneal, fallopian tube, endometrial cancer, or triple negative breast cancer (TNBC).

SECONDARY OBJECTIVES:

  1. To explore the toxicity, response rate (RR) and progression free survival (PFS) in three expanded cohorts of heavily pre-treated FRalpha-positive a) TNBC patients; b) endometrial cancer patients; and c) ovarian, primary peritoneal, or fallopian tube cancer patients, all treated at the initial recommended phase II dose.

II. To provide additional safety data from the expanded cohorts to help inform on the RP2D for each cohort.

III. To evaluate the relationship between intratumoral levels of DM4, tumoral expression of FRalpha, and plasma concentration of DM4 at 48 and 72 hours following the first dose.

IV. To determine the pharmacokinetics (PK) of DM4 and gemcitabine when given in combination.

EXPLORATORY OBJECTIVE:

  1. To evaluate the role of archival FRalpha expression as a substitute for the 48-72 hour (H) expression in determining intratumoral concentration of DM4.

OUTLINE: This is a dose escalation study.

Patients receive mirvetuximab soravtansine intravenously (IV) on day 1 and gemcitabine hydrochloride IV over 30 minutes on days 1 and 8. Cycles repeat every 3 weeks in the absence of disease progression or unexpected toxicity.

After completion of study treatment, patients are follow up at 30 days and then every 12 weeks thereafter.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Gemcitabine, Gemcitabine Hydrochloride and Laboratory Biomarker Analysis in people with Recurrent Breast Carcinoma and Recurrent Fallopian Tube Carcinoma, run by City of Hope Medical Center at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 21 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recommended phase II dose assessed by Common Terminology Criteria for Adverse Events version 4 (time frame: Up to 3 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02996825.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2026.
