Summary
Brief summary (as posted)
This phase II trial is studying how well trastuzumab works in treating patients with locally advanced or metastatic gallbladder cancer or bile duct cancer that cannot be removed by surgery. Monoclonal antibodies, such as trastuzumab, 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

Arms and outcomes
Arms (1)
- type
- EXPERIMENTAL
- label
- Trastuzumab
- description
- Participants receive trastuzumab loading dose 8 mg/kg intravenous (IV) over 30-90 minutes on day 1 and subsequent maintenance doses of 6 mg/kg over 90 minutes then every 30 minutes starting at the third dose. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Primary outcomes (1)
- measure
- Objective Response (Complete and Partial Response)
- timeFrame
- Baseline to 63 days or until disease progression
- description
- Response assessed using imaging-based evaluation at baseline then following single agent trastuzumab administered over 21 day cycle, re-staging done following 2 cycles. Response Evaluation Criteria in Solid Tumors defined as Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): At least a 30% decrease in sum of longest diameter (LD) of target lesions, taking as reference the baseline sum LD; Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions; Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.
