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


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 or unacceptable toxicity.



Inclusion and Exclusion Criteria

  • Has histologically confirmed recurrent adult-type granulosa cell tumor of the ovary prior to first dose of study treatment
  • Have documented radiological evidence of relapse after at least one systemic therapy that is not amenable to surgery, or radiation and have measurable disease by RECIST v1.1 criteria
  • Have adequate bone marrow, renal and hepatic function as defined by screening visit laboratory values Key

  • Has signs of bowel obstruction requiring parental nutrition, malabsorption syndrome or preexisting gastrointestinal conditions that may impair absorption of nirogacestat
  • Has had a major cardio or thrombo-embolic event within 6 months of signing informed consent
  • Has abnormal QT interval at Screening, or has congenital or acquired long QT syndrome or a history of additional risk factors for Torsades de Pointes
  • Has current or chronic history of liver disease or known hepatic or biliary abnormalities
  • Has received any 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: anti-angiogenic therapy, hormonal therapy, chemotherapy, immunotherapy, targeted therapy or any investigational treatment
