This phase 2 clinical trial will study the effectiveness of nirogacestat in ovarian granulosa cell tumors (OvGCTs). Nirogacestat is a gamma secretase inhibitor (GSI) which is hypothesized to decrease the growth and activity of ovarian granulosa tumors.

Official Title

A Phase 2 Trial of Nirogacestat in Patients With Recurrent Ovarian Granulosa Cell Tumors


Ovarian granulosa cell tumors (OvGCTs) represent 5-7% of all ovarian cancers (~1.5 to 2k newly diagnosed patients/year in the United States) and are the most common subtype of ovarian sex cord tumors (70%). Treatment of granulosa cell tumors with nirogacestat is expected to inhibit Notch-induced granulosa cell proliferation.

This is a multi-center, single-arm, Phase 2 open label treatment study to determine the efficacy, safety, tolerability, and pharmacokinetics of nirogacestat in adult participants with relapsed/refractory OvGCT. The participants will continue treatment until disease progression as determined by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 (unless the participants meet criteria for continued treatment) or unacceptable toxicity.
