|Condition or disease||Intervention/treatment||Phase|
|Gastrointestinal Stromal Tumor||Drug: Sorafenib Tosylate||Phase 2|
I. To determine the objective response rate of patients with imatinib and sunitinib-resistant malignant gastrointestinal stromal tumor who are treated with BAY 43-9006.
I. To determine the toxicity experienced by patients with imatinib and sunitinib -resistant malignant gastrointestinal stromal tumor who are treated with BAY 43-9006.
II. To determine progression-free survival and overall survival in patients with imatinib and sunitinib -resistant malignant gastrointestinal stromal tumor who are treated with BAY 43-9006.
I. To examine if mutational status of KIT and PDGFA in patients with imatinib- and sunitinib resistant malignant gastrointestinal stromal tumor correlate with response to BAY 43-9006.
OUTLINE: This is a multicenter study. Patients are stratified according to response to prior treatment with imatinib mesylate and sunitinib malate (imatinib mesylate- and sunitinib malate-responsive disease vs primary imatinib mesylate- and sunitinib malate-refractory disease).
Patients receive oral sorafenib twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed periodically.

|Official Title:||A Phase 2 Study of BAY 43-9006 for Imatinib- and Sunitinib Resistant Gastrointestinal Stromal Tumor|
|Actual Study Start Date :||September 14, 2005|
|Actual Primary Completion Date :||February 11, 2010|
Experimental: Treatment (sorafenib tosylate)
Patients receive oral sorafenib twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Drug: Sorafenib Tosylate
- Objective Response Rate [ Time Frame: Up to 5 years ]
Objective response (complete response (CR)+ partial response (PR)) will be evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) criteria. CR is the disappearance of all target lesions. PR requires at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD.
Computed Tomography (CT) scans for disease reassessment will be obtained pre-therapy and every 8 weeks. In addition to a baseline scan, confirmatory scans will also be obtained 4 weeks following initial documentation of objective response.
- Progression-free Survival [ Time Frame: Up to 5 years ]
Progression-free survival will be defined as time from the start of treatment until progression (documented according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria and defined as at least a 20% increase in the sum of the longest diameter of target lesions) or death, whichever comes first.
CT scans for disease reassessment will be obtained pre-therapy and every 8 weeks.
- Overall Survival [ Time Frame: Up to 5 years ]Overall survival will be defined as time from the start of treatment until death from any cause.
