Clinical Trial Summary

For locally advanced esophagogastric junction and gastric cancer (cT3-4aNxM0 or cT2N+M0), neoadjuvant chemotherapy can downstage T and N stage,treated distant micrometastases early before local therapy has begun, and finally improve the long-term survival. Combination of perioperative PD-1 antibody and chemotherapy for locally advanced esophagogastric junction and gastric cancer could be a novel therapy to increase response rate and reduce recurrence rate. JS001 in this study is a Chinese anti-PD-1 monoclonal antibody for injection which has been approved for melanoma. This study is a multi-center, open-label, randomized phase II clinical trial to evaluate safety and efficacy of JS001 in combination with perioperative chemotherapy in locally advanced esophagogastric junction and gastric cancer. Differences in gut microbiome and tumor immune microenvironment were detected to screen people who were more sensitive to immunotherapy.

Description:

Gastric cancer (GC) is one of the leading causes of cancer-related deaths worldwide and a substantial global health burden. Surgery is the only possible way to cure gastric cancer, however, more than 80% of the Chinese patients are diagnosed at advanced stages. Locally advanced esophagogastric junction and gastric cancer (cT3-4aNxM0 or cT2N+M0) could be cured by multi-disciplinary therapies including surgery, chemotherapy and radiotherapy. Neoadjuvant chemotherapy can downstage T and N stage, treated distant micrometastases early before local therapy has begun, and finally improve the long-term survival. However, the therapeutic effects remain unsatisfactory. PD-1 antibody has demonstrated its efficacy in metastatic gastric cancer and has been proved to be effective in neoadjuvant setting in lung cancer and melanoma. Combination of perioperative PD-1 antibody and chemotherapy for locally advanced esophagogastric junction and gastric cancer could be a novel therapy to increase response rate and reduce recurrence rate. JS001 in this study is a Chinese anti-PD-1 monoclonal antibody for injection which has been approved for melanoma. This study is a multi-center, open-label, randomized phase II clinical trial to evaluate safety and efficacy of JS001 in combination with perioperative chemotherapy in locally advanced esophagogastric junction and gastric cancer. Differences in gut microbiome and tumor immune microenvironment were detected to screen people who were more sensitive to immunotherapy.
