About this trial

The purpose of this study is to evaluate whether a single dose of Nivolumab in people living with HIV can reduce the latent reservoir. The latent HIV reservoir is a group of immune system cells in the body that are infected with HIV but are not actively producing new virus. This is the reason why people living with HIV are unable to stop their antiretroviral treatment.

    Drug

    Cohort B: Randomization phase: Nivolumab will be administered intravenously as a fixed single dose (1.0 mg/kg) in the randomization phase.

  • Saline

    Drug

    Cohort B: Randomisation phase: Saline will be administered intravenously as a single dose in the randomisation arm.
