Brief Summary

The purpose of this study is to evaluate Safety and tolerability of MASCT-I in patients with advanced solid tumors, either alone or in combination with chemical drugs or in combination with PD1 antibody.

Detailed Description

The multiple-antigen specific cell therapy which was developed by Hengrui Yuanzheng is optimized continuously and has been upgraded from the first-generation MASCT technology to MASCT-I. MASCT-I is a technology which add PD1 antibody in vitro cell culture process of MASCT cell culture to block PD1 receptor on immunocytes, release the brake on immunocytes' reinfusion and interaction with tumor cells for enhancing the efficacy of immunocytes' killing tumor cells. At present, the development and validation of manufacturing process has been completed, and it is urgently needed to conduct the validation of clinical effect.

This is a Multi-center, phase I clinical study to evaluate the safety and tolerability of multiple antigen stimulating cellular therapy-I (MASCT-I) in patients with advanced solid tumor, and to preliminarily evaluate the anti-tumor efficacy of MASCT-I alone, in combination with chemical drugs, and in combination with PD1 antibody. About 193 cases of adult patients with advanced solid tumors will be recruited.
