Purpose
Patients with metastatic or locally advanced gastrointestinal stromal tumors (GIST) who develop resistance against the two hitherto approved drugs for this disease, the tyrosin kinase inhibitors (TKIs) imatinib and sunitinib, have a poor prognosis. Sometimes a further response may be achieved by other drugs, mainly other TKIs, which have been explored in different studies but not yet have been approved for clinical use. Pazopanib is a TKI inhibiting the tyrosin kinases KIT, PDGFRA, and VEGF 1-3, all of which have important roles in the pathogenesis of GIST. Theoretically, it may function in GIST, and it deserves investigational trials. The drug is approved for metastatic renal cancer and is relatively well tolerated. In this trial (SSG XXI), the disease control rate (DCR) = (CR+PR+SD) after 12 weeks of treatment will be assessed as the primary endpoint, and at the same time trough levels will be measured. Secondary endpoints include ORR, PFS, toxicity, and disease control rate in relation to trough level week 12 and in relation to the primary mutation of the tumor (if known). The goal is to include 72 patients in the trial, which is open and single arm.

- Disease control rate [ Time Frame: Week 12 ] [ Designated as safety issue: No ]The ratio of patients with CR (complete remission) + PR (partial remission) + SD (stable disease) at week 12 after start of treatment
- Progression free survival (PFS) [ Time Frame: The patients will be followed for the duration of the trial treatment, an expected average of 6 months ] [ Designated as safety issue: No ]Progression free survival (KM analysis) for all patients administered the study drug
- DCR in relation to mutation [ Time Frame: Week 12 ] [ Designated as safety issue: No ]Disease control rate as described above in relation to the type of mutation of the primary tumor if this is available (not mandatory)
- DCR in relation to plasma concentration [ Time Frame: Week 12 ] [ Designated as safety issue: No ]Disease control rate as defined above in relation to the trough level (plasma concentration) of the study drug at week 12
- Toxicity [ Time Frame: The patients will be followed for the duration of the trial treatment + 1 month, an expected average of 7 months ] [ Designated as safety issue: Yes ]Recording of adverse events including SAE/SAR for all patients administered the study drug
- Overall response rate [ Time Frame: The patients will be followed for the duration of the trial treatment, an expected average of 6 months ] [ Designated as safety issue: No ]ORR = CR+PR at the time of best response during the study period
