•Complete gross resection of the tumor
•Risk of relapse documented as intermediate and high” according to NIH criteria:
•1. High risk category:

•Prior participation in an adjuvant GIST trial
•Prior treatment with imatinib
•Treatment with any cytotoxic and/or investigational cytotoxic drug = 4 weeks (6 weeks for nitrosurea or mitomycin C) prior to Visit 1
•Patients with known history of hypersensitivity against imatinib
•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
•Use of therapeutic coumarin derivatives (i.e. warfarin, acenoucumarol, phenprocoumon)

•A history of noncompliance to medical regimens or inability or unwillingness to return for scheduled visits
•Patients who are pregnant, breast feeding or women of childbearing potential (WOCBP). Post menopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential Women of reproductive potential, to include female partners of heterosexual or bisexual patients, must agree to use an effective method of contraception during the study and for up to three months following termination of the study.
