Brief Summary

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.

Detailed Description

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.

  • Has current or chronic history of liver disease or known hepatic or biliary abnormalities
  • Has received bevacizumab treatment or other monoclonal antibody therapy with targeted anti-angiogenic activity for OvGCT within 28 days (or 5 half-lives, whichever is shorter) prior to the first dose of study treatment;
  • Has received treatment for OvGCT including but not limited to the following within 28 days (or 5 half-lives, whichever is longer) prior to the first dose of study treatment: hormonal therapy, chemotherapy, immunotherapy, targeted therapy or any investigational treatment

Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)2.5 years

The proportion of participants with complete response (CR) + partial response (PR) assessed using RECIST v1.1 criteria.

Secondary Outcome Measures
NameTimeMethod
Overall Survival2 years after first dose of study treatment

The number of participants who have not died of any cause.

Progression Free Survival at 6 months (PFS-6)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.

Duration of ResponseFirst 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

Participant reported ovarian cancer symptomsAt 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).
