Apatinib
Brief summary
This study makes an observation over the objective response rate of Apatinib and 5-Fu combination regimen in the three-line treatment of metastatic colorectal cancer. All the participants will randomly receive the treatment of Apatinib and 5-Fu combination regimen or 5-Fu.
Detailed description
5-Fu chemotherapy is an effective therapy for colorectal cancer. Apatinib is a small-molecule tyrosine kinase inhibitor (TKI) that highly selectively binds to and strongly inhibits vascular endothelial growth factor receptor 2 (VEGFR-2), with a decrease in VEGF-mediated endothelial cell migration, proliferation, and tumor microvascular density. A phase II trail of Apatinib has been demonstrated that Apatinib is safe to treat the metastatic colorectal cancer and the disease control rate can reach 50%.

Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedure.
Exclusion criteria
* History of other malignancies except cured basal cell carcinoma of skin and carcinoma in-situ of uterine cervix * Pregnant or lactating women * Preexisting uncontrolled hypertension defined as more than 140/90 mmHg despite using single medical therapy, more than class I (NCI CTCAE 3.0 ) myocardial ischemia, arrhythmia(including QTcF:male ≥ 450 ms, female ≥ 470 ms), or cardiac insufficiency myocardial ischemia, arrhythmia, or cardiac insufficiency * Before or at the same time any, second malignancies except cured basal cell carcinoma of skin and carcinoma in-situ of uterine cervix * Any factors that influence the usage of oral administration Evidence of CNS metastasis * URT: urine protein ≥ (++)and \> 1.0 g of 24 h * PT, APTT, TT, Fbg abnormal, having hemorrhagic tendency (eg. active peptic ulcer disease) or receiving the therapy of thrombolysis or anticoagulation * Abuse of drugs * Certain possibility of gastric or intestine hemorrhage * Less than 4 weeks from the last clinical trial * Viral hepatitis type B or type C * Prior VEGFR inhibitor treatment * Evidence of significant medical illness that in the investigator's judgment will substantially increase the risk associated with the subject's participation in and completion of the study
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| ORR | From assignment of the first subject to 3 months later after the last participant is recruited. | The percentage of subjects with total number of Complete Response (CR) + total number of Partial Response (PR) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| DCR | From assignment of the first subject to 3 months later after the last participant is recruited. | DCR is defined as the percentage of subjects whose best response was not Progressive Disease (PD) according to Response Evaluation Criteria in Solid Tumors (RECIST) (= total number of Complete Response (CR) + total number of Partial Response (PR) + total number of Stable Disease (SD) |
| PFS | From assignment of the first subject to 3 months later after the last participant is recruited. | PFS was defined as the time from assignment to disease progression radiological/clinical or death due to any cause, whichever occurs first. Subjects without progression or death at the time of analysis were censored at their last date of tumor evaluation. |
| OS | From assignment of the first subject until 30 death events observed, up to 2 years. | OS is defined as the time from date of assignment to death due to any cause. Subjects still alive at the time of analysis were censored at their last date of last contact. |
| QoL | From assignment of the first subject to 3 months later after the last participant is recruited. | The general well-being of participants, outlining negative and positive features of life. |
