Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

* HIV-1 plasma RNA <50 copies/mL for >2 years (documented on at least 2 occasions within the 2 years) and <50 copies/mL at screening. Episodes of a single HIV plasma RNA 50-500 copies/mL will not exclude participation if the subsequent HIV plasma RNA was <50 copies/mL;
* CD4+ T cell counts >500 cells/µL at screening;
* Female participants if they meet one of the following criteria:

* Is of non-child-bearing potential defined as either post-menopausal (12 months of spontaneous amenorrhea and = 45 years of age) or physically incapable of becoming pregnant with documented tubal ligation, hysterectomy or bilateral oophorectomy or,

Note: If using one of the described contraception methods it must be used consistently, in accordance with the approved product label and all female participants must be willing to undergo urine pregnancy tests as specified in the Schedule of Procedures.

* agree on the use of an effective method of contraception with an effective failure rate of < 1% by his partner (hormonal contraception, intra-uterine device (IUD), or anatomical sterility) from the day of the first infusion until the end of study (as long as plasma viral load <20c/mL).

Summary
Brief summary
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.
