Effect of Chidamide Combined With CAT-T or TCR-T Cell Therapy on HIV-1 Latent Reservoir

To study the safety and effectiveness of the combination of Chidamide with Chimeric Antigen Receptor(CAR)-T or T cell receptor(TCR)-T cell therapy on HIV patients based on cART.

Despite the advent of combined antiretroviral therapy (cART), the persistence of viral reservoirs remains a major barrier to cure human immunodeficiency virus type 1 (HIV-1) infection. Recently, the shock and kill strategy, by which such reservoirs are eradicated following reactivation of latent HIV-1 by latency-reversing agents (LRAs), has been extensively practiced. It is important to reestablish virus-specific and reliable immune surveillance to eradicate the reactivated virus-harboring cells. Some studies have shown that Chidamide can highly activate the HIV reservoirs. The VC-CAR-T cells effectively induced the cytolysis of LRA-reactivated HIV-1-infected CD4 T lymphocytes isolated from infected individuals receiving suppressive cART. Our previous study demonstrated that the special features of genetically engineered CAR-T cells make them a particularly suitable candidate for therapeutic application in efforts to reach a functional HIV cure. The purpose of this study is to evaluate the safety and efficacy of Chidamide together with Chimeric Antigen Receptor(CAR)-T or T cell receptor(TCR)-T cell therapy based on cART in HIV-infected adults whose plasma HIV has been successfully suppressed after cART.

The control arm includes HIV-infected patients without receiving cellar therapy combined with Chidamide whose HIV-1 has been successfully suppressed after cART.

Receiving chidamide combined with CAR-T or TCR-T cell therapy based on based on cART after attaining plasma HIV suppression (plasma HIV RNA <50 cp/ ml) and CD4+ cell count more than 350 cells/ul over 1 year by cART without active HCV or HBV infection or opportunistic infections.

Not receiving chidamide combined with CAR-T or TCR-T cell therapy but continuing cART after attaining plasma HIV suppression (plasma HIV RNA <50 cp/ml) and CD4+ cell count more than 350 cells/ul over 1 year by cART, without active HCV or HBV infection or opportunistic infections.

Inclusion Criteria: HIV infection confirmed Receiving cART more than 12 months. HIV viral-load < 50 copies/ml and CD4 cell count more than 350 cells/ul. Without serious liver , heart, liver and kidney diseases. The subjects know about the study and volunteer to attend the research and sign the informed consent. Exclusion Criteria: With active HBV or HCV infection, or serious opportunistic infections. With serious chronic disease such like diabetes, the mental illness,et al History of suffering from pancreatitis during cART . Pregnant or breast-fed. With poor adherence. Unable to complete follow up.
