A Study of Ripretinib vs Sunitinib in Advanced GIST Patients After Treatment With Imatinib
United States, Argentina, Australia453 participantsStarted 2019-02-08
Plain-language summary
This is a 2-arm, randomized, open-label, international, multicenter study comparing the efficacy of ripretinib to sunitinib in GIST patients who progressed on or were intolerant to first-line anticancer treatment with imatinib. Approximately 426 patients will be randomized in a 1:1 ratio to ripretinib 150 mg once daily (continuous dosing for 6 week cycles) or sunitinib 50 mg once daily (6 week cycles, 4 weeks on, 2 weeks off).

Inclusion criteria
. Patients ≥ 18 years of age at the time of informed consent.
. Histologic diagnosis of GIST and must be able to provide an archival tumor tissue sample, otherwise, a fresh biopsy is required.
. Molecular pathology report must be available. If molecular pathology report is not available or insufficient, an archival tumor tissue sample or fresh biopsy is required for mutation status confirmation by the central laboratory prior to randomization.
. Patients must have progressed on imatinib or have documented intolerance to imatinib.
. Eastern Cooperative Oncology Group (ECOG) Performance Score (PS) of ≤ 2 at screening.
. Female patients of childbearing potential must have a negative serum beta-human chorionic gonadotropin (β-hCG) pregnancy test at screening and negative pregnancy test at Cycle 1 Day 1 prior to the first dose of study drug.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Progression Free Survival (PFS) in the KIT Exon 11 Intent to Treat (ITT) Population
Timeframe: From date of randomization to earliest documented evidence of disease progression, or death due to any cause (up to 2.1 years)
2
Progression Free Survival (PFS) in the All Patient (AP) Intent to Treat (ITT) Population
Timeframe: From date of randomization to earliest documented evidence of disease progression, or death due to any cause (up to 2.1 years)
. Patients of reproductive potential must agree to follow the contraception requirements outlined in the study protocol.
. Patients must have at least 1 measurable lesion according to Modified Response Evaluation Criteria in Solid Tumors (mRECIST) Version 1.1 (non nodal lesions must be ≥ 1.0 cm in the long axis or ≥ double the slice thickness in the long axis) within 21 days prior to the first dose of study drug.
Exclusion criteria
. Treatment with any other line of therapy in addition to imatinib for advanced GIST. Imatinib-containing combination therapy in the first-line setting is not allowed.
. Patients with a prior or concurrent malignancy whose natural history or treatment have the potential to interfere with the safety or efficacy assessment of this clinical trial are not eligible.
. Patient 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.
. Left ventricular ejection fraction (LVEF) \< 50% at screening.
. Arterial thrombotic or embolic events such as cerebrovascular accident (including ischemic attacks) or hemoptysis within 6 months before the first dose of study drug.
. Venous thrombotic events (e.g. deep vein thrombosis) or pulmonary arterial events (e.g. pulmonary embolism) within 1 month before the first dose of study drug. Patients on stable anticoagulation therapy for at least one month are eligible.
. 12-lead ECG demonstrating QT interval corrected (QTc) by Fridericia's formula \> 450 ms in males or \> 470 ms in females at screening or history of long QTc syndrome
