研究概览
简要总结
This phase II trial studies how well savolitinib works in treating patients with MET amplified colorectal cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Savolitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
详细描述
PRIMARY OBJECTIVE:
I. To estimate the objective response rate (ORR) of savolitinib in patients with MET amplified metastatic colorectal cancer (CRC).
SECONDARY OBJECTIVES:
I. To describe the clinical activity (duration of response, progression free survival [PFS]) of savolitinib in patients with MET amplified metastatic CRC.
II. To describe the toxicities of savolitinib in patients with MET amplified metastatic CRC.

研究组 & 干预措施
Treatment (savolitinib)
Experimental
Patients receive savolitinib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
干预措施: Savolitinib (Drug)
结局指标
主要结局
Objective Response Rate (ORR) as Measured by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1)
时间窗: From start of treatment until documented progression of disease (up to 4 months)
Objective response rate is calculated as the number of people with a complete or partial response divided by the total number of people treated. Complete response is defined as disappearance of all target lesions. Partial response is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
次要结局
- Months of Progression-Free Survival (PFS)(From start of treatment until documented progression of disease (up to 4 months))
