Ripretinib vs Sunitinib for Gastrointestinal Stromal Tumor
(INSIGHT Trial)
Trial Summary
The trial protocol does not specify if you must stop taking your current medications, but you cannot use strong or moderate inhibitors or inducers of cytochrome P450 (CYP) 3A or consume grapefruit within 14 days before starting the study drug.
Ripretinib is effective as a fourth-line treatment for gastrointestinal stromal tumors, showing increased progression-free survival compared to placebo in the INVICTUS trial. Although it is not superior to sunitinib in second-line treatment, it has a better safety profile with fewer severe side effects.
12345Ripretinib has a better safety profile compared to Sunitinib, with fewer severe side effects like high blood pressure. It is generally well-tolerated, with common side effects including increased lipase levels, fatigue, and low phosphate levels in the blood.
12346Ripretinib is unique because it is designed to target a broad range of mutations that can develop resistance to other treatments, and it has a better safety profile with fewer severe side effects compared to sunitinib.
12345Eligibility Criteria
