INSIGHT: This study is comparing two types of targeted therapy in people with gastrointestinal stromal tumours (GIST) who have progressed on prior treatment with imatinib and have other specific mutationsAn International, Phase 3, Randomized, Multicenter, Open-label Study of Ripretinib vs Sunitinib in Patients With Advanced GIST With KIT Exon 11 and Co-occurring KIT Exons 17 and/or 18 Mutations Who Were Previously Treated With Imatinib

Clinical summary


Eligible participants will be randomly allocated to one of two treatment arms.

In the Experimental Arm, participants will receive 150mg of Ripretinib once daily (as 3 x 50mg oral tablets). Ripretinib will be given continuously in repeated 42-day cycles.

In the Active Comaprator Arm, participants will receive 50mg of Sunitinib once daily (as 4 x 12.5mg capsules). Sunitinib will be given continuously for 4 weeks with a 2-week break.


This trial is treating patients with advanced gastrointestinal stromal tumours (GIST) with KIT Exon 11 and co-occurring KIT Exons 17 and/or 18 mutations who were previously treated with Imatinib
