This is an open label, uncontrolled, multicenter, phase II study to evaluate the efficacy and safety of Gemcitabine/Pazopanib combination as 1st line treatment in patients with unresectable, locally advanced or metastatic biliary tree adenocarcinoma. A total of 46 patients will be included in the study. The patients will receive open label Gemcitabine 1000 mg/m2 intravenously on days 1 and 8 and Pazopanib 800 mg per os on days 1 to 21 every 21 days. Treatment with gemcitabine/pazopanib combination will continue until disease progression, appearance of significant toxicity, completion of 8 cycles or informed consent withdrawal. Upon completion of 8 treatment cycles with the combination, and in the absence of disease progression, administration of pazopanib monotherapy as maintenance treatment will be continued until disease progression, appearance of significant toxicity or informed consent withdrawal.~Imaging assessments will be performed every 8 weeks
The purpose of this study is to determine whether gemcitabine and pazopanib are effective in the treatment of inoperable, locally advanced or metastatic biliary tree cancer (cholangiocarcinoma or gallbladder carcinoma).
