A Study of INCB123667 in Participants With Platinum-Resistant Ovarian Cancer With Cyclin E1 Overexpression

Summary

This study will evaluate the safety and efficacy of INCB123667 in Participants With Platinum-Resistant Ovarian Cancer (PROC) With Cyclin E1 Overexpression.

Eligibility

Inclusion Criteria:

* Histological diagnosis of a high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer.
* Have platinum-resistant disease:

  * Participants who have only had 1 line of platinum-based therapy must have received at least 4 cycles of a platinum-containing regimen.
  * Participants who have received 2 to 4 lines of platinum-based therapy must have progressed on or within 6 months after the last dose of platinum.
* Willingness to undergo a pretreatment biopsy. Note: Tissue from a fresh pretreatment biopsy is preferred, however an archival sample is acceptable as long as the sample is no older than 5 years.
* Received at least 1 and no more than 4 prior lines of systemic therapy following the initial diagnosis, after which single-agent therapy is considered an appropriate next therapeutic option.
* Must have received bevacizumab unless there was a contraindication for its use.
* If the tumor tests positive for FRα, participants must have received mirvetuximab soravtansine unless there is an exception for its use on medical grounds.

Exclusion Criteria:

* Have endometrioid, clear cell, mucinous, or sarcomatous histology, mixed tumors containing any of these histologies, or low-grade/borderline ovarian cancer.
* Have primary platinum-refractory disease: either did not respond (CR or PR) to first-line platinum-containing therapy or progressed on or within 3 months after the last dose of the first line platinum-containing therapy.
* The tumor tests positive for FRα but the participant has not received mirvetuximab soravtansine for any reason other than medical contraindication.
* Clinically significant or uncontrolled cardiac disease within 6 months before the first dose of study drug.
* Known active CNS metastases and/or carcinomatous meningitis.
* Known additional malignancy that is progressing or requires active treatment.

Other protocol-defined Inclusion/Exclusion Criteria may apply.
