Enrollment: 30
Study Start Date: June 2008
Study Completion Date: January 2012
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: imatinib Drug: imatinib mesylate


Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • patients with age between 18 and 80 years
  • diagnosis of GIST not previously treated
  • Patients will be included in the protocol regardless of operability; in the case of an operable tumor, patients are eligible if, in the opinion of the surgeon, resection would be suboptimal, disfiguring or functionally disabling (i.e. incomplete resection or other which cold compromise severely the quality of life or other GI function)

Exclusion criteria:

  • presence of metastatic disease
  • use of other antineoplastic treatment (chemotherapy, immunotherapy, radiotherapy)

Other protocol-defined inclusion/exclusion criteria may apply.
