简要总结
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).
详细描述
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

排除标准
- •Prior malignancy.Subjects with a history of completely resected non-melanomatous skin carcinoma or successfully treated in situ carcinoma or indolent prostate cancer are eligible (even if they are receiving antihormonal therapy).
- •Central nervous system (CNS) metastases at baseline, with the exception of those subjects who have previously-treated CNS metastases are asymptomatic and have no requirement for steroids or enzyme-inducing anticonvulsants in the past 6 months.
- •Clinically significant gastrointestinal abnormalities that may increase the risk for gastrointestinal, 28 days prior to study treatment initiation.
- •Clinically significant gastrointestinal abnormalities that may affect absorption of investigational product including malabsorption syndrome, major resection of the stomach
- •Corrected QT interval (QTc) >480 milliseconds using Bazett's formula
- •History of myocardial infarction, unstable angina, symptomatic peripheral vascular disease or Class II,III or IV congestive heart failure, as defined by the New York Heart Association (NYHA) or cardiac angioplasty or stenting within the past 6 months

- •Major surgery or trauma within 28 days prior to first dose of study drug and/or presence of any non-healing wound, fracture,or ulcer (procedures such as catheter placement not considered to be major).
- •Evidence of active bleeding or bleeding diathesis.
- •Known endobronchial lesions and/or lesions infiltrating major pulmonary vessels that increase the risk of pulmonary hemorrhage
- •Recent hemoptysis (≥ ½ teaspoon of red blood within 8 weeks of first dose of study drug).
- •Any serious and/or unstable pre-existing medical,psychiatric, or other condition that could interfere with subject's safety,provision of informed consent,or compliance to study procedures.
