简要总结
The primary goal of the trail was to determine the efficacy of combining Gemcitabine and Docetaxel in treatment of metastatic colorectal cancer with CHFR and/or Microsatellite Instability (MSI) phenotype.
详细描述
This was an open-label, multicenter, trial. Enrolled patients received an intravenous combination of gemcitabine 800 mg/m2 on days 1 and 8 and docetaxel 70 mg/m2 on day 8 of each 21-day cycle. Patients received filgrastim (granulocyte colony-stimulating factor [G-CSF]) on days 9 through 15 or pegfilgrastim 6 mg on day 9 or 10 of each cycle. Patients were treated until disease progression or unacceptable adverse events (AEs), or withdrawn of the consent.
Patients underwent safety evaluations and monitoring for adverse events for each cycle.
Disease assessments (computed tomography or magnetic resonance imaging) were performed at baseline and then every 6 weeks. Response was evaluated according to the RECIST version1.1.
Patients who discontinue treatment will be monitored for overall survival.

排除标准
- •Patients who have had chemotherapy or radiotherapy within 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.
- •Patients who are receiving any other investigational agents.
- •Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
- •History of allergic reactions attributed to compounds of similar chemical or biologic composition to gemcitabine or docetaxel.
- •Patients receiving any medications or substances that are inhibitors or inducers of CYP 3A4 are ineligible. Lists including medications and substances known or with the potential to interact with the cytochrome 450 3A4 isoenzyme are provided in appendix C.
- •Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- •Pregnant women are excluded from this study because of the potential for teratogenic or abortifacient effects of study medications. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with gemcitabine and docetaxel breastfeeding should be discontinued if the mother is treated. These potential risks may also apply to other agents used in this study including supportive medications.
- •HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with gemcitabine and docetaxel. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.

结局指标
主要结局
Response Rate
时间窗: 9 months
The Response Rate is defined as the number of patients achieving a complete response (CR) or partial response (PR) based on the Response Evaluation Criteria in Solid Tumors (RECIST 1.1). CR = disappearance of all target lesions, PR is =\>30% decrease in sum of diameters of target lesions, progressive disease (PD) is \>20% increase in sum of diameters of target lesions, stable disease (SD) is \<30% decrease or \<20% increase in sum of diameters of target lesions.
次要结局
- Overall Survival With Gemcitabine and Docetaxel Combination Therapy(62 months)
- Progression-free Survival (PFS)(9 months)
