Nirogacestat in Ovarian Granulosa Cell Tumors

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

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.

Study Overview

• Status: Completed
• Conditions: Ovarian Cancer; Ovarian Granulosa Cell Tumor; Ovarian Granulosa-Stromal Tumor
• Intervention / Treatment: Drug: Nirogacestat

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective Response Rate (ORR)	The proportion of participants with complete response (CR) + partial response (PR) assessed using RECIST v1.1 criteria.	2.5 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression Free Survival at 6 months (PFS-6)	The number of participants without progression according to RECIST v1.1 or death at 6 months.	First day of cycle 7 (approximately 6 months after the first dose of study treatment). Each cycle is 28 days.
Overall Survival	The number of participants who have not died of any cause.	2 years after first dose of study treatment
Participant reported ovarian cancer symptoms	Change from baseline as measured by Functional Assessment of Cancer Therapy - Ovarian Symptom Index (FOSI).	At each study visit until study completion (estimated to be an average of 2.5 years)
