A Study of Ripretinib Vs Sunitinib in Patients with Advanced GIST with Specific KIT Exon Mutations Who Were Previously Treated with Imatinib

Description

This is a Phase 3, 2-arm, randomized, open-label, global, multicenter study comparing the efficacy of ripretinib to sunitinib in participants with GIST who progressed on first-line treatment with imatinib, harbor co-occurring KIT exons 11+17/18 mutations, and are without KIT exon 9, 13, or 14 mutations. Upon disease progression as determined by an independent radiologic review, participants randomized to sunitinib will be given the option to either crossover to receive ripretinib 150 mg QD or discontinue sunitinib.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. Male or female ≥18 years of age.
  • 2. Histologic diagnosis of GIST with co-occurring KIT exons 11+17/18 mutations confirmed by ctDNA sample.

  • 4. Eastern Cooperative Oncology Group (ECOG) performance status (PS) of ≤2 at screening.
  • 5. Female participants of childbearing potential must have a negative pregnancy test at screening and prior to the first dose of study drug.
  • 6. Participants of reproductive potential must agree to follow contraception requirements.
  • 7. Participants must have at least 1 measurable lesion according to mRECIST v1.1 within 21 days prior to the first dose of study drug.
  • 8. Adequate organ function and bone marrow reserve based on laboratory assessments performed at screening.
  • 9. Resolution of all toxicities from prior therapy to Grade ≤1 (or participant baseline) within 1 week prior to the first dose of study drug.
  • 1. History of KIT exon 9 mutation or detection of KIT exon 9, 13, or 14 mutations in a ctDNA sample.
  • 2. Has known active central nervous system metastases.

New York Heart Association Class II-IV heart disease, myocardial infarction within 6 months of Cycle 1 Day 1, active ischemia or any other uncontrolled cardiac condition such as angina pectoris, clinically significant cardiac arrhythmia requiring therapy, uncontrolled hypertension, or congestive heart failure.
  • 4. Use of strong or moderate inhibitors or inducers of cytochrome P450 (CYP) 3A prior to the first dose of study drug, and consumption of grapefruit or grapefruit juice within 14 days prior to the first dose of study drug.
  • 5. Major surgeries (eg, abdominal laparotomy) within 4 weeks of the first dose of study drug.
  • 6. Known human immunodeficiency virus or hepatitis C infection only if the participant is taking medications that are excluded per protocol, acute or chronic hepatitis B, or acute or chronic hepatitis C infection.
  • 7. Gastrointestinal abnormalities including, but not limited to:
