E.2.2 | Secondary objectives of the trial |
To provide patients with GIST in an adjuvant setting with expanded access to imatinib until local commercial availability of the drug for this stage of the disease To explore the relationship of tumor characteristics (KIT and PDGFR mutations) as measured in tumor tissue with clinical outcome for patients where tumor tissue is available. To evaluate the population pharmacokinetics of imatinib |
