Eventual development of resistance to both imatinib and sunitinib is nearly universal. There is no standard therapy when this occurs, and patients should be considered for investigational therapy. Additional oral TKIs are under investigation. For example, in a preliminary case series, nilotinib has shown biological activity, with unknown impact on survival.
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with gastrointestinal stromal tumor. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
