Brief Summary

This study is being conducted to study how nirogacestat may affect the ovarian function of adult premenopausal women with progressing desmoid tumors/aggressive fibromatosis.

Conditions

Desmoid Tumor; Aggressive Fibromatosis

Keywords

Nirogacestat; PF-03084014; GSI; gamma secretase inhibitor; notch pathway; Ogsiveo

Outcome Measures

Primary Outcomes (1)

• Ovarian function recovery rate of ovarian toxicity (OT) treatment-emergent adverse events (TEAEs)

  Ovarian function recovery is defined as achieving the resumption of ≥2 consecutive menstrual periods and an FSH level \<30 mIU/mL with concomitant estradiol \<80 pg/mL OR resumption of ≥2 consecutive menstrual periods and AMH level within normal range adjusted for age and pretreatment baseline OR a positive serum β-HCG pregnancy test.

  Up to 24 cycles (each cycle is 28 days) of treatment and up to 2 years in the Clinical Follow-up Period

Secondary Outcomes (3)

• Incidence of OT TEAEs

  Up to 24 cycles (each cycle is 28 days) of treatment and up to 2 years in the Clinical Follow-up Period

• Time to ovarian function recovery in participants with a TEAE of OT

  Up to 24 cycles (each cycle is 28 days) of treatment and up to 2 years in the Clinical Follow-up Period

• The incidence of adverse events (AEs) according to toxicities graded by National Cancer Institute (NCI) Common Technology Criteria for Adverse Events (CTCAE) Version 5

  Up to 24 cycles (each cycle is 28 days) of treatment and up to 2 years in the Clinical Follow-up Period

Other Outcomes (10)

• Objective Response Rate (ORR)

  First day of every 3 cycles (each cycle is 28 days) for up to 24 cycles of treatment and up to 1 year in the Clinical Follow-up Period

• Duration of Response (DoR) for participants whose best response is CR or PR

  First day of every 3 cycles (each cycle is 28 days) until disease progression is observed or death, whichever comes first, up to 24 cycles of treatment and up to 1 year in the Clinical Follow-up Period

• Disease Control Rate (DCR) for participants whose best response is CR, PR or Stable Disease (SD)

  First day of every 3 cycles (each cycle is 28 days) for up to 24 cycles of treatment and up to 1 year in the Clinical Follow-up Period

• Age Groups: Adult (18-64)

You may qualify if:

• Participant is female, postpubertal aged ≥18 and ≤40 years of age at the time of signing the informed consent and premenopausal at baseline. Premenopausal is defined as meeting all of the following: Estradiol \>30 pg/mL. Follicle-stimulating hormone (FSH) \<40 IU/L. Regular menses (e.g., menstrual cycle length of 21 to 35 days) for at least 3 menstrual cycles prior to signing informed consent
• Participant uses 1 highly effective non-hormonal contraceptive method, has a negative pregnancy test prior to first dose of study treatment), is not breastfeeding, agrees to not harvest or donate eggs for at least 90 days prior to and during the study
• Participant has histologically confirmed DT/AF with symptomatic or progressive disease requiring systemic treatment
• Participant has an Eastern Cooperative Oncology Group (ECOG) performance status ≤2 at screening
• Participant has adequate organ and bone marrow function.

You may not qualify if:

• Participant has known malabsorption syndrome or preexisting gastrointestinal conditions that may impair absorption of nirogacestat
• Participant has experienced any of the following within 6 months of signing informed consent: clinically significant cardiac disease (New York Heart Association Class III or IV), myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft, symptomatic congestive heart failure, cerebrovascular accident, transient ischemic attack, or symptomatic pulmonary embolism.
• Participant has had lymphoma, leukemia, or any malignancy within the past 5 years at the time of informed consent, except for any locally recurring cancer that has been treated curatively (e.g., resected basal or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of the cervix or breast), with no evidence of metastatic disease for 3 years at the time of informed consent.
• Participant has known hepatic impairment
• Participant previously received or is currently receiving gamma secretase inhibitors or anti-Notch antibody therapy
• Participant is currently using any treatment for DT/AF including tyrosine kinase inhibitors (TKIs) or any investigational treatment 28 days (or 5 half-lives, whichever is longer) prior to the first dose of study treatment
• Participant is currently using or anticipates using food or drugs that are known strong/moderate cytochrome P450 (CYP) 3A4 inhibitors, or strong CYP3A inducers within 14 days prior to the first dose of study treatment.
• Participant has a history of polycystic ovary syndrome, hypothalamic amenorrhea, severe endometriosis involving ovaries, family history of primary ovarian insufficiency, any chromosomal abnormality, mutation, gene variant or medical condition associated with early/premature menopause, including a history of OT while on a TKI
• Participant is currently using or has used hormonal contraception or ovarian suppression within 90 days prior to first dose of study treatment
• Participant has a history of heavy tobacco smoking (≥20 pack years) or is a current smoker (\>1 pack per day)
• Participant has experienced other severe acute or chronic medical or psychiatric conditions within 1 year of signing informed consent.
• Participant is unable to comply with study related procedures (including, but not limited to, the completion of a menstrual diary and electronic patient-reported outcomes and ability to return to clinic for hormone level blood draws timed to the menstrual cycle (days 1-5)
