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 to add PD1 antibody in vitro cell culture process of MASCT technology to block PD1 receptor on immunocytes, relieving the brake at immunocytes' reinfusion and interaction with tumor cells for enhancing the effectiveness of immunocytes killing tumor cells.
This is a phase I study to evaluate the safety and tolerance of MASCT-I combined with PD1 antibody in patients with advanced gastric cancer who failed in first-line chemotherapy.
About 19-28 cases patients with advanced gastric cancer are to be recruited.
This study is divided into three stages:
The first, second stage is the stage of the dose climbing, and the third stage is the dose expansion stage. The first stage is MASCT-I, using 3+3 design, if the DLT≥33.3% from the mononuclear cell collection to 14 days after the first MASCT-I infusion of T cells,the experiment will be end. If the DLT<33.3%, enter the second stage. The second stage is divided into two groups: MASCT-I+PD1 antibody in low dose group and MASCT-I+PD1 antibody in high dose group, using 3+3 design, if all patients in low dose group, the DLT≥33.3% from the mononuclear cell collection to 14 days after the first MASCT-I infusion of T cells, the experiment will be end. If DLT<33.3% began high dose group. If all the patients in the high dose group, DLT ≥33.3%, the corresponding high dose group treatment will be terminated, entered the third stage, the dose of expansion, only by low dose treatment group of 10 patients of reentry. If all the patients in the high dose group, DLT<33.3%, entered the third stage. Only 10 patients in the high dose group were treated with the corresponding high-dose group.

Experimental: MASCT-I or MASCT-I +PD1 antibody
This study is divided into three stages: The first, second stage is the stage of the dose climbing, and the third stage is the dose expansion stage. The first stage is MASCT-I, using 3+3 design. The second stage is divided into two groups: MASCT-I+PD1 antibody in low dose group and MASCT-I+PD1 antibody in high dose group, using 3+3 design. The third stage is the dose expansion stage , 10 patients in the low or high dose group were treated with the corresponding dose group. |
The final products of MASCT-I(Multiple-antigen specific cell therapy) technology are dendritic cells (DC) and effector T cells.Treatment with MASCT-I alone, conducted until disease progression, intolerance or end of study.
Drug: PD1 antibody 1mg/kg or 3mg/kg. Administration is conducted in Day1 and Day15. Conducted until disease progression, intolerance or end of study.
