Resumption of imatinib to control metastatic or unresectable gastrointestinal stromal tumours after failure of imatinib and sunitinib (RIGHT): a randomised, placebo-controlled, phase 3 trial.

ABSTRACT:

Background

Few treatment options remain for patients with metastatic or unresectable gastrointestinal stromal tumours (GIST) after objective progression on approved tyrosine-kinase inhibitors. We aimed to assess efficacy of imatinib rechallenge in these patients.

Methods

In our prospective, randomised, double-blind trial, we enrolled adults (≥18 years) who had previously benefited from first-line imatinib (initial response or stable disease for ≥6 months) but whose metastatic or unresectable GIST had progressed on at least imatinib and sunitinib. We randomly allocated participants in a 1:1 ratio, with a centralised computer-generated allocation procedure (random permuted blocks of two, four, and six) and stratified by previous treatment and Eastern Cooperative Oncology Group
