pazopanib in combination with interferon alfa 2-a, in patients with advanced renal cell carcinoma

Conditions: Advanced Renal Cell Carcinoma

Summary: phase i / ii, open, prospective, multicenter single-arm, clinical trial in two stages: in the first stage it will determine the optimal dose of the combination of pazopanib and interferon alfa-a2 in the treatment of patients with advanced renal carcinoma and a second stage that will determine the efficacy of this combination measured in terms of response rate.
