Plain language summary: the CHAPTER-GIST-301 study of pimitespib for treating late-stage digestive tract tumors

This document presents a patient-friendly summary of the phase 3 INTRIGUE clinical trial results, which were published in the Journal of Clinical Oncology in August 2022. A phase 3 trial is a study that tests the safety of a proposed treatment and how well it works compared with a standard treatment or a treatment with no active ingredient (also called a placebo). The aim of the INTRIGUE trial was to understand whether treatment with a drug called ripretinib (brand nameQINLOCK®) was superior to treatment with sunitinib (brand name SUTENT®) in participants with advanced gastrointestinal stromal tumor (also known as GIST) who cannot tolerate or whose disease progressed beyond first-line treatment with imatinib (brand name GLEEVEC®). The INTRIGUE trial included 453 participants with advanced GIST who had previously been treated with a tyrosine kinase inhibitor (also known as a TKI) medicine called imatinib. For patients with advanced GIST who cannot tolerate or whose disease progresses while taking imatinib, the recommended second-line TKI medicine is sunitinib. The recommended third-line TKI medicine is called regorafenib (brand name STIVARGA®). Ripretinib is currently the only medication approved for adults with advanced GIST who have previously been treated with 3 or more TKIs (fourth-line).
