Study Endpoints

Primary Endpoints

Progression Free Survival (PFS) Defined as the Time From Randomization Until Date of Assessment of Progression or Death by Any Cause.
On the first day of every 3 cycles (each cycle is 28 days) until disease progression is observed or death, whichever comes first, assessed up to approximately 2 years

Progression will be determined radiographically using RECIST v1.1 (Eisenhauer, 2009) or clinically as assessed by the investigator. Clinical progression is defined as the onset or worsening of symptoms resulting in a global deterioration of health status causing the permanent discontinuation from study treatment and the initiation of emergent treatment (e.g., radiotherapy, surgery, or systemic therapy including chemotherapy or tyrosine kinase inhibitors) for DT/AF. Events of clinical progression will be adjudicated by an independent blinded central Endpoint Adjudication Committee (EAC) which will qualify events of clinical progression for inclusion in the PFS endpoint prior to study unblinding according to an EAC Review Charter.

Objective response rate (ORR)
On the first day of every 3 cycles (each cycle is 28 days) until disease progression is observed or death, assessed up to approximately 3 years.

Objective response rate (ORR), defined as the proportion of participants with confirmed complete response (CR) + partial response (PR) assessed by independent Central Imaging Review using RECIST v1.1 (Eisenhauer 2009).

Incidence of Adverse Events, Graded According to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version (v) 5.0
through study completion; an average of 1 year.
Clinical Benefit per RECIST v1.1
1 year

Clinical benefit (CB) is defined as the number of participants assessed with a complete response (CR), partial response (PR), or stable disease (SD) within 1 year and with no evidence of loss of response nor progression within that year. Response \& progression will be assessed according to the Revised Response Evaluation Criteria in Solid Tumors (RECIST)v1.1, as follows: RECIST v1.1: * CR=Disappearance of all lesions * PR=≥30% decrease in diameter of target lesions * Progressive disease (PD)=20% increase in diameter of target lesion; progression of non-target lesion; or ≥1 new lesion(s) For the overall outcome: * SD=Changes not meeting above criteria * Overall Response (OR)=CR+PR * CB=CR+PR+SD

Progression-free survival (PFS)
Up to 2 years from study entry

The Kaplan-Meier method will be used to estimate the 2-year PFS defined as the time from study entry until disease progression or death from any cause.

Percentage of patients experiencing grade 3+ adverse events (AE)
Up to 6 years from study entry

Percentage of patients experiencing grade 3 or higher AEs will be evaluated according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. All grade 1 and 2 toxicities observed in \> 5% of participants and deemed related to study drug will be reported.

Pharmacokinetic (PK) parameter: systemic exposure
Up to Cycle 3 (each cycle lasts 28 days)

PK parameters of nirogacestat will be defined to quantify systemic exposure, drug clearance, terminal half-life and other pharmacokinetic characteristics. These PK parameters will be summarized with descriptive statistics, including means, medians, ranges, and standard deviations.

PK parameter: drug clearance
Up to Cycle 3 (each cycle lasts 28 days)

PK parameters of nirogacestat will be defined to quantify systemic exposure, drug clearance, terminal half-life and other pharmacokinetic characteristics. These PK parameters will be summarized with descriptive statistics, including means, medians, ranges, and standard deviations.

PK parameter: half-life
Up to Cycle 3 (each cycle lasts 28 days)

PK parameters of nirogacestat will be defined to quantify systemic exposure, drug clearance, terminal half-life and other pharmacokinetic characteristics. These PK parameters will be summarized with descriptive statistics, including means, medians, ranges, and standard deviations.

Secondary Endpoints

Objective Response Rate Using RECIST Version 1.1 Criteria.
On the first day of every 3 cycles (each cycle is 28 days) through study completion, an average of 2 years
Change From Baseline at Cycle 10 in the Brief Pain Inventory (BPI) Average Pain Intensity (API) Score.
Daily for the last 7 days of every cycle (each cycle is 28 days) through study completion, an average of 2 years

Frequently asked questions about Nirogacestat

What is Nirogacestat used for?

Nirogacestat is an investigational small molecule being studied for desmoid fibromatosis, also called desmoid tumor or aggressive fibromatosis, and for ovarian granulosa-stromal tumors. It is in Phase 2 clinical development and has received FDA designations including Priority Review, Fast Track, Orphan Drug, and Breakthrough Therapy.

What does Nirogacestat target?

Nirogacestat is an inhibitor of the gamma-secretase complex, targeting the presenilin and nicastrin components PSEN1, PSEN2, NCSTN, APH1A, APH1B, and PSENEN. By inhibiting this complex, it is designed to interfere with Notch pathway signaling, which is implicated in desmoid tumor growth.

Who is developing Nirogacestat?

Nirogacestat is being developed by SpringWorks Therapeutics, Inc., which trades under the ticker SWTX. The company is running Phase 2 studies of the oral tablet in desmoid tumors and ovarian granulosa cell tumors across the United States, Canada, Poland, and Japan.

What phase is Nirogacestat in?

Nirogacestat is in Phase 2 clinical development. It is investigational and has not been approved by the FDA. The program includes completed and ongoing Phase 2 trials, with one active trial, one completed trial, and additional studies recruiting or active but not recruiting.

What clinical trials is Nirogacestat in?

Nirogacestat trials include NCT07170644 in Japanese adults with desmoid tumors, NCT05949099 studying cryoablation plus nirogacestat in desmoid tumor, NCT05879146 evaluating response and non-response in desmoid tumors, and NCT05348356 in ovarian granulosa cell tumors, which is completed.

Is Nirogacestat the same as Nirogacestat Hydrobromide?

Yes. Nirogacestat Hydrobromide and nirogacestat oral tablet are alternative names for nirogacestat, the small molecule developed by SpringWorks Therapeutics. Searches for any of these names refer to the same investigational Phase 2 drug candidate being studied in desmoid tumors and ovarian granulosa-stromal tumors.
