Evaluation of the Response and Non-response of Nirogacestat in Desmoid Tumors- Clinical Study

Launched by M.D. ANDERSON CANCER CENTER · May 18, 2023

ClinConnect Summary

This clinical trial is studying the safety and effectiveness of a new drug called nirogacestat for patients with desmoid tumors, which are rare tumors that can be aggressive. The trial is looking for about 40 adults aged 18 and older who have been diagnosed with these tumors and have seen their tumors grow in size recently. Participants should be able to tolerate some tumor growth, have measurable tumors, and agree to provide tissue samples for testing.

If you or a loved one is considering joining this trial, you can expect to take nirogacestat in pill form and undergo regular check-ups, including imaging tests and biopsies to monitor tumor response. The study is currently recruiting participants, and eligibility criteria include having good overall health and no major uncontrolled health issues. It’s important to note that pregnant or breastfeeding women cannot participate due to potential risks. This trial aims to provide valuable insights into how well nirogacestat works and its safety for people with desmoid tumors.

Eligibility criteria

• Inclusion Criteria:
• This study will enroll approximately 40 participants diagnosed with DT. Participants must meet the following eligibility criteria to be enrolled:
• • 1. Age ≥ 18 years. Individuals younger than 18 years old are excluded. More than 99% of the population evaluated at MDACC with a diagnosis of DT is older than 18. Sixty-three percent of the population with a diagnosis of DT evaluated at MDACC are 10 - 54 years old. The remaining 37 percent are older than 54 years old. Additionally, most of the robust data related to dosing or adverse event data currently available on the use of nirogacestat is in adults
• • 2. Histologically documented DT with evidence of radiographic tumor progression (≥ 10% or absolute increase in dimensions of ≥ 10 mm in maximal diameter) in unidimensional measurement within the previous 18 months. Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension as ≥10 mm (≥1 cm) with CT scan, MRI, or calipers by clinical exam
• • 1. Recurrent or primary disease
• • 2. Symptomatic disease or impending morbidity (as defined by physician) and patient and physician agree treatment would be of benefit
• • 3. Treatment naïve or progression on or after any prior therapy for DT. Participant must have discontinued prior therapy for at least 28 days or 5 half-lives of the drug, whichever is greater. All toxicities from prior therapy must be resolved to Grade ≤ 1 or clinical baseline. There is no limit on the number of previous systemic treatments received
• • 4. Able to tolerate radiographic progression (up to 20% increase in tumor longest diameter) as determined by treating oncologist based on morbidity and tumor growth is not threatening vital structures
• • 5. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
• • 6. Are appropriate for systemic therapy
• • 7. Have accessible tumors for serial biopsies
• • 8. Agree to provide new tumor tissue. Tumor tissue from the archival (tumor bank) may be used if the biopsy is performed after discontinuation of prior therapy and the participant must have discontinued prior therapy for at least 28 days or five half-lives of the drug, whichever is greater
• • 9. For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
• • 10. Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
• 11. Adequate organ and bone marrow function as defined by the following screening laboratory values:
• • 1. Absolute neutrophil count ≥ 1500 cells/μL;
• • 2. Platelets ≥ 100,000 μL;
• • 3. Hemoglobin ≥ 9 g/dL;
• • 4. Total bilirubin ≤ 1.5 × upper limit of normal (ULN) (isolated bilirubin \> 1.5 x ULN is acceptable if bilirubin is fractionated and direct bilirubin \< 35%);
• • 5. Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase)/alanine aminotransferase (ALT) (serum glutamic pyruvate transaminase) ≤ 2 × ULN; and
• • 6. If Creatinine \> 1.5 x ULN then calculated creatinine clearance must be . 60 mL/min (using the Cockcroft-Gault formula).
• • 12. Can swallow tablets and have no gastrointestinal conditions affecting absorption
• • 13. Agree to the use of adequate contraception during the treatment period and for at least 4 months for men and women after the last dose of the study treatment (see Appendix 1 for more information)
• • 14. Have the ability to understand and the willingness to sign a written informed consent document
• • 15. English and non-English speaking patients
• • 16. Participants with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this study
• • 17. Participants with a known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification; to be eligible for this study, participants should be class 2B or better
• Exclusion Criteria:
• Participants are excluded from this study if any of the following criteria apply:
• • 1. Unable to undergo serial biopsies
• • 2. Participants with familial adenomatous polyposis
• • 3. Unable to tolerate MRI or for whom MRI is contraindicated
• • 4. Pregnant or breastfeeding women are excluded from this study. Based on findings in animal studies, oral administration of nirogacestat to pregnant rats during the period of organogenesis resulted in embryo-fetal toxicities at maternal exposures that were significantly lower than adult human exposures at the recommended dose of 150 mg twice daily. Nirogacestat should be avoided during pregnancy
• • There is no data regarding the presence of nirogacestat or its metabolites in either human or animal milk or its effects on a breastfed child or on milk production. Because of the potential for serious adverse reactions in a breastfed child from nirogacestat, advise women not to breastfeed during treatment with nirogacestat.
• • 5. Known hypersensitivity to nirogacestat or any of its excipients
• • 6. Participants requiring the use of any excluded concomitant medications listed in Table 2 during the course of the study
• • 7. Unable to comply with study-related procedures in the opinion of the investigator
• • 8. Patients with cognitive impairment requiring a legally authorized representative for consent
• • 9. Patients with uncontrolled intercurrent illness (Indicate clearly what type or extent)
• • 10. Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with positive viral load will be excluded
• • 11. Patients with psychiatric illness/social situations that would limit compliance with study requirements
• • 12. Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities \> Grade 1) with the exception of alopecia
• • 13. Patients who are receiving any other investigational agents
• • 14. Patients with an additional malignancy and brain metastases. There is not enough evidence of the effects of nirogacestat in other malignancies at this time
• 15. Participant has experienced any of the following within 6 months of signing informed consent:
• • 15.1 clinically significant cardiac disease (New York Heart Association Class III or IV); 15.2 myocardial infarction; 15.3 severe/unstable angina; 15.4 coronary/peripheral artery bypass graft; 15.5 symptomatic congestive heart failure; 15.6 cerebrovascular accident; 15.7 transient ischemic attack; or 15.8 symptomatic pulmonary embolism.
