Immunological Non-Responders in People With HIV

This study focuses on people with HIV who experience incomplete immune reconstitution despite suppressive antiretroviral therapy (ART), characterized by persistently low CD4⁺ T cell counts and residual inflammation. The underlying cause is largely attributed to the persistent HIV latent reservoir. Recent evidence indicates that rilpivirine, a non-nucleoside reverse transcriptase inhibitor (NNRTI) commonly used in ART, has an immunomodulatory function beyond its antiviral activity. It activates the CARD8 inflammasome - an intracellular "kill switch" - triggering pyroptosis selectively in HIV-infected cells. In this study, rilpivirine will be added to suppressive ART in patients with incomplete immune reconstitution. The investigators hypothesize that this strategy will reduce the latent reservoir, restore CD4⁺ T cell counts and function, attenuate excessive immune activation, and ultimately improve long-term clinical outcomes.
