Ovarian Granulosa-Stromal Tumor Ovarian Granulosa Cell Tumor Ovarian Cancer | Drug: Nirogacestat | Phase 2 |
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 or unacceptable toxicity.

- Objective Response Rate (ORR) [ Time Frame: 2.5 years ]The proportion of participants with complete response (CR) + partial response (PR) assessed using RECIST v1.1 criteria.
- Progression Free Survival at 6 months (PFS-6) [ Time Frame: First day of cycle 7 (approximately 6 months after the first dose of study treatment). Each cycle is 28 days. ]The number of participants without progression according to RECIST v1.1 or death at 6 months.
- Overall Survival [ Time Frame: 2 years after first dose of study treatment ]The number of participants who have not died of any cause.
- Participant reported ovarian cancer symptoms [ Time Frame: At each study visit until study completion (estimated to be an average of 2.5 years) ]Change from baseline as measured by Functional Assessment of Cancer Therapy - Ovarian Symptom Index (FOSI).
- Duration of Response [ Time Frame: First day of every other cycle (each cycle is 28 days) for the first year, and then every 3 cycles thereafter until study completion (estimated to be an average of 2.5 years). ]The time from response (CR + PR using RECIST v.1.) to disease progression and/or death
