Clinical Trial Summary

This is a single-arm,open-label, prospective, single-center Study of QL1101 and JS001 in patients with pMMR/MSS refractory metastatic colorectal cancer.

QL1101 is a biosimilar of bevacizumab (Avastin) produced and provided by Qilu Pharmaceutical Co., Ltd., which has been marketed in China.It's a humanized monoclonal IgG1 antibody prepared by recombinant DNA technology. By binding to human vascular endothelial growth factor (VEGF), it inhibits the binding of VEGF to its receptor, blocks the signal transduction pathway of angiogenesis, and inhibits tumor cell growth. Be produced and provided by Shanghai Junshi Bioscience Co., Ltd. ,JS001(Tripleitriumab) is the first China-developed humanized monoclonal antibody against programmed death 1 (PD-1) approved for marketing in China.

Antiangiogenic drugs combined with PD-1 monoclonal antibodies may reverse the insensitivity of pMMR/MSS refractory colorectal cancer to PD-1 inhibitors.

The primary objective of this study is to investigate the safety and efficacy of the subjects who given the combination therapy.

Outcome

Type Measure Description Time frame Safety issue
Primary Progression-free survival (PFS) Will be estimated using the Kaplan-Meier method, and Cox proportional hazards models will be used to estimate the treatment hazard ratios. PFS will use a logrank test stratified on the randomization stratification factors with a one-sided type I error rate of 2.5%. From the first use of research drugs to documented disease progression per RECIST 1.1 and iRECIST or death from any cause, whichever occurs first, assessed up to 18 months
Secondary Overall survival (OS) Will be estimated using the Kaplan-Meier method, and Cox proportional hazards models will be used to estimate the treatment hazard ratios. OS will be tested at the one-sided 10% level. From the first use of research drugs to death from any cause, assessed up to 18 months
Secondary Overall response rate(ORR) Best objective response will be evaluated via RECIST 1.1 and iRECIST criteria. Will be compared using Fisher's exact tests with a one-sided type I error rate of 2.5%; multivariable logistic regression modeling will be used to adjust for the effect of any covariates that are associated with these categorical outcomes. up to 18 months
Secondary Disease Control Rate (DCR) Disease control is defined as maintaining Complete Response (CR) or Partial Response (PR) or Stable Disease (SD) as the tumor assessment result during the defined time window. DCR (percentage) is defined as number of patients with success of disease control divided by total number of patients in the analysis population multiplied by 100, excluding patients who refuse treatment before the initiation of any treatment. CR: Disappearance of all evidence of disease, PR: Regression of measurable disease and no new sites, PD: Any new lesion or increase by =50% of previously involved sites from nadir, SD: Neither sufficient shrinkage to qualify for PR, nor sufficient increase to qualify for PD taking as reference the MSD up to 18 months
Secondary Duration of Response (DOR) The distribution of DOR by treatment group will be estimated using the method of Kaplan-Meier. Six and 12 month durable response (i.e. maintaining CR or PR without progressive disease [PD]) rates by treatment group with confidence intervals will be estimated based on Kaplan-Meier curves. The HR with confidence interval will be estimated based on stratified Cox models (stratified by levels of stratification factors), without and with adjusting for baseline clinical/pathological factors.CR: Disappearance of all evidence of disease, PR: Regression of measurable disease and no new sites, PD: Any new lesion or increase by =50% of previously involved sites from nadir From the date of first tumor assessment with the response status being CR or PR to the date of 1st documented progressive disease, assessed up to 12 months
