Publication number: 20240115627Abstract: The present disclosure relates to use of a Clostridium ghonii spore combined with pembrolizumab in cancer treatment. It is found for the first time that the Clostridium ghonii spore combined with pembrolizumab can significantly improve a curative effect of colon cancer and reduce a dose of the pembrolizumab, and thus is efficient and low-toxic. Oncolysis by Clostridium ghonii can affect immunogenicity of a tumor microenvironment (TME) by various ways, converts an immunosuppressive state of the TME into an immune-activated state, adjusts the immunosuppressive TME, and breaks an immune tolerance. An optimal combination of the Clostridium ghonii spore and the pembrolizumab thoroughly removes about 20% of mouse tumor tissues. A benefit range of patients with tumors treated by a PD-1 antibody is expanded. The combination even has an obvious curative effect on patients failed the treatment by the PD-1 antibody.Type: ApplicationFiled: October 9, 2022Publication date: April 11, 2024Inventors: Yong Wang, Hong Zhu, Wenhua Zhang, Yanqiu Xing, Dan Wang, Yuanyuan Liu, Shaopeng Wang, Jiahui Zheng, Rong Zhang, Xiaonan Li, Xinglu Xu, Shengbiao Jiang, Lichao Xing, Yuxia Gao, Shili Shao, Ting Han
