Neoantigen Reactive T Cells Combined With SHR-1210 for Chinese Patients With Advanced Refractory Solid Tumors

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to see the safety and efficient of neoantigen reactive T cells (NRTs) combined with programmed cell death-1(PD-1) inhibitor（SHR-1210）in the treatment of Chinese patients with advanced refractory solid tumors.

Detailed Description
-----------------
The tumor-specific none-self immunogenic neoantigens encoded by either viral genes or somatic mutation genes, possess the potential to induce specific anti-cancer immunity, including cellular and humoral immune responses. Today, numerous clinical trials demonstrate that although these none-self antigens initiate the antigen-specific immunoglobulin G antibodies and cluster of differentiation 4（CD4）+/cluster of differentiation 8（CD8）+T-cells response, not all of them show a clinical benefit in the response rate, progression-free survival or overall survival.Immune tolerance induced by PD-1 or programmed cell death-ligand1（ PD-L1）maybe play a vital role for these negative outcomes.Personalized cell therapy plus checkpoint inhibitors maybe own a breakthrough in the treatment of those malignant diseases without standard options.Our center has successfully established a new method for preparing personalized neoantigen reactive T cells(NRTS) for adoptive cell therapy(ACT). Today, we will carry out a single center single arm clinical prospective study of NRTs combined with PD-1 inhibitor(SHR-1210) for the treatment of Chinese patients with advanced refractory solid tumors. Participants are assigned to receive 4 circles of cell therapy,and prior to each cycle's immunocytes treatment,preconditional chemotherapy and SHR-1210 will be carried out, and IL-2 continuous intravenous infusion（CIV） will also be given for 5 consecutive days after each time's cell infusion. The safety and clinical response rate（RR） are evaluated. Biomarkers and immunological markers are also monitored.
