CLINICAL STUDIES The clinical safety and efficacy of SUTENT has been studied in the treatment of patients with malignant gastrointestinal stromal tumour (GIST) who were resistant to imatinib (i. e. those who experienced disease progression during or following treatment with imatinib) or intolerant to imatinib (i. e. those who experienced significant toxicity during treatment with imatinib that precluded further treatment) and the treatment of patients with metastatic renal cell carcinoma (MRCC) Efficacy is based on time to tumour progression and an increase in survival in GIST and on progression free survival and objective response rates for treatment-naïve and cytokine-refractory MRCC respectively.
