Spots Global Cancer Trial Database for Recombinant Anti-tumor and Anti-virus Protein for Injection in Treatment of Metastatic Colorectal Cancer

Study Description

Brief Summary: The purpose of this study is to evaluate the efficacy and safety of recombinant anti-tumor and anti-virus protein for injection in treating patients with metastatic colorectal cancer after failure of second-line and more than second-line treatment.

Detailed Description: Explanation for study design The trial including two stages. The first is an exploration stage to decide delivery frequency and dose of study drug. It is single-blinded, subjects will be randomly divided into 4 groups with a 2:2:2:1 ratio. Study drug given twice per week or 3 times per, dose of the drug are from 20μg to 40μg. The sample size is 105, duration is 12 to 18 months. Based on preliminary efficacy and safety, the better dosage regimen will decided for the second stage.The second stage is double-blinded,subject will be randomly divided into treatment group or placebo group with 2:1 ratio and sample size is 600. Primary purpose To compare overall survival between study drug and placebo groups . Secondary purpose 1. Progression free survival were compared in both groups. 2. Disease control rate were compared in both groups. 3. Quality of life scores were compared in both groups. 4. Determine the safety and tolerance of recombinant anti-tumor and anti-virus protein for injection 5. Supplementary pharmacodynamics of recombinant anti-tumor and anti-virus protein for injection Exploratory purpose Evaluate effects of recombinant anti-tumor and anti-virus protein for injection on the anti-tumor immunity, angiogenesis, apoptosis, cell proliferation, immune cells and cytokines levels.
