简要总结
This phase II trial is studying how well giving bevacizumab together with erlotinib hydrochloride works in treating patients with metastatic or unresectable biliary tumors. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Bevacizumab and erlotinib hydrochloride may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving bevacizumab together with erlotinib hydrochloride may kill more tumor cells.
详细描述
PRIMARY OBJECTIVES:
I. Evaluate the objective response rate in patients with metastatic or unresectable cholangiocarcinoma treated with bevacizumab and erlotinib hydrochloride.
SECONDARY OBJECTIVES:
I. Evaluate time to progression in these patients.
II. Evaluate overall and progression-free survival of these patients.

研究组 & 干预措施
Bevacizumab and Erlotinib Hydrochloride
Patients receive 5 mg/kg bevacizumab IV over 30-90 minutes on days 1 and 15 and 150 mg oral erlotinib hydrochloride daily on days 1-28. Courses repeat every 28 days in the absence of unacceptable toxicity or disease progression.
Tumor tissue and blood specimens are collected periodically for correlative studies. Specimens are examined by immunohistochemistry for epidermal growth factor receptor (EGFR) and P-EGFR protein levels; AKT p-AKT, mitogen-activated protein kinase (MAPK) and P-MAPK protein levels; and vascular endothelial growth factor receptor (VEGFR)-1 and VEGFR-2 protein levels. EGFR mutations are detected by laser capture microdissection. Enzyme-linked immunosorbent assay is used to measure total and free serum VEGF levels.

结局指标
主要结局
Number of Confirmed Tumor Responses.
时间窗: After 6 courses of treatment. Each course lasts 28 days.
Complete Response (CR): Disappearance of all target lesions. Partial Response (PR): At least a 30% decrease in the target lesions. A confirmed tumor response is defined to be either a Complete Response or a Partial Response noted as the objective status on 2 consecutive evaluations at least 4 weeks apart. Confirmed tumor responses will be evaluated using the first 6 cycles of treatment. All patients meeting the eligibility criteria who have signed a consent form and have begun treatment and had one post-baseline disease assessment will be evaluable for response. Forty-nine of the 53 eligible patients had at least one post-baseline disease assessment and were evaluable for this endpoint.
次要结局
- Time to Disease Progression(From registration to documentation of disease progression, assessed up to 3 years)
- Survival Time(From registration to death due to any cause, assessed up to 3 years)
- Duration of Response(From the date at which the patient's objective status is first noted to be either a CR or PR to the date progression is documented, assessed up to 3 years)
