• Patients must have histologically or cytologically confirmed GIST with a D842-related mutation or deletion on the PDGFRA gene
• Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >20 mm with conventional techniques or as >10 mm with spiral CT scan. See Section 10.1.2 for the evaluation of measurable disease.

You may not qualify if…

• Patient unable to provide informed consent

• Patients on concomitant medications that induce or inhibit CYP3A4 (Appendix III)
• Patients with severe and/or uncontrolled concurrent medical disease that in the opinion of the investigator could cause unacceptable safety risks or compromise compliance with the protocol e.g. impairment of gastrointestinal (GI) function, or GI disease that may significantly alter the absorption of the study drugs
