简要总结
This phase II trial is studying how well RO4929097 (gamma-secretase/Notch signalling pathway inhibitor RO4929097) works in treating patients with previously treated metastatic pancreatic cancer. RO4929097 may stop the growth of tumor cells by blocking some enzymes needed for cell growth.
详细描述
PRIMARY OBJECTIVES:
I. To determine the 6-month survival of patients with previously treated metastatic pancreas cancer treated with gamma secretase RO4929097.
II. To determine the adverse events of RO4929097 in this patient population. III. To correlate changes in tumor markers with RO4929097 exposure.
SECONDARY OBJECTIVES:
I. To evaluate the response rate and overall survival of this population treated with RO4929097.

研究组 & 干预措施
Treatment (RO4929097)
Patients receive gamma-secretase/Notch signalling pathway inhibitor RO4929097 PO once daily on days 1-3, 8-10, and 15-17. Courses repeat every 21 days for up to 24 months in the absence of disease progression or unacceptable toxicity.
Patients may undergo tumor biopsy at baseline and on days 16 or 17 of course one for biomarker and other correlative studies. Blood samples may also collected at baseline and periodically during study for pharmacokinetic and angiogenesis marker studies.
干预措施: gamma-secretase/Notch signalling pathway inhibitor RO4929097 (Drug)
结局指标
主要结局
Survival Rate
时间窗: 6 months
The primary endpoint of the study was 6-month survival. The proportion of successes was estimated by the number of successes divided by the total number of evaluable patients.
次要结局
- Survival(From registration to death due to any cause, assessed up to 2 years)
- Time to Disease Progression(From registration to documentation of disease progression, assessed up to 2 years)
