IMGN151 alone or with carboplatin, olaparib, or bevacizumab for adults with high-grade serous gynecologic cancers

A Phase 1b Dose Escalation and Expansion Study of IMGN151 as Monotherapy and in Combination With Other Anti-Cancer Therapies in Subjects With Gynecologic Cancers

Phase 2 Interventional AbbVie · NCT07024784

This trial tests whether IV IMGN151, given alone or with carboplatin, olaparib, or bevacizumab, can reduce disease activity and be safely tolerated in adults with high-grade serous ovarian, fallopian tube, or primary peritoneal cancer.

What this trial studies

This Phase 2, multi-center trial plans to enroll about 377 adults with high-grade serous ovarian, fallopian tube, or primary peritoneal cancer into four treatment arms. Participants receive intravenous IMGN151 as monotherapy or combined with carboplatin, olaparib, or bevacizumab, administered in repeated treatment cycles. The study tracks changes in disease activity (using RECIST v1.1 for most participants), adverse events, and tolerability. Enrollment requires ECOG performance status 0–1 and adherence to timing rules after prior therapies.

Who should consider this trial

Good fit: Adults with high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who have ECOG 0–1, meet prior therapy timing windows, and (for most arms) have at least one measurable lesion are the intended participants.

Not a fit: Patients with excluded tumor histologies (endometrioid, clear cell, mucinous, or sarcomatous), poor performance status, or who cannot meet prior therapy timing or measurable disease requirements are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If successful, IMGN151 could provide a new treatment option that shrinks tumors or extends response duration with an acceptable safety profile for patients with these gynecologic cancers.

How similar studies have performed: Antibody–drug conjugates and combinations with PARP inhibitors or platinum agents have shown promise in ovarian cancer, but IMGN151 itself remains investigational and unproven.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* ECOG performance status of 0 or 1
* Participants (except for platinum-sensitive ovarian, fallopian tube, and primary peritoneal cancer (PSOC) participants without disease progression after platinum combination standard of care therapy in Arms B and D) will have ≥ 1 lesion that meets the definition of measurable disease by RECIST v1.1 (radiographically measured by the investigator).
* Participants will have high-grade serous epithelial ovarian, fallopian tube, and primary peritoneal cancers (EOC).
* Participant has completed prior therapy within the specified times below:

  * Systemic antineoplastic therapy within 5 half-lives or 4 weeks (whichever is shorter) prior to the first dose of IMGN151.
  * Focal radiation completed ≥ 2 weeks prior to the first dose of study treatment.

Exclusion Criteria:

* Participants with ovarian cancer with histologies including: endometrioid, clear cell, mucinous, or sarcomatous histology, mixed tumors containing any of the above histologies, as well a low-grade or borderline ovarian tumor.
* History of clinically significant medical conditions or any other reason that the investigator determines would interfere with the participant's participation in this study or would make the participant an unsuitable candidate to receive study treatment.
* Prior treatment with FRα-targeting therapy.
* Prior wide-field radiotherapy affecting more than 20% of the bone marrow.
