A Randomized, Double-Blinded, Placebo-Controlled Trial Comparing Antiretroviral Intensification With Maraviroc and Dolutegravir With No Intensification or Intensification With Dolutegravir Alone for the Treatment of Cognitive Impairment in HIV

HIV-infected people often have cognitive dysfunction (HIV-associated neurocognitive disorder, or HAND), which includes asymptomatic neurocognitive impairment (ANI), mild neurocognitive disorder (MND), and HIV-associated dementia (HAD), even if they are on ART and have undetectable viral loads. In this study, researchers evaluated the effectiveness of adding MVC and DTG to the current ART regimen of HIV-infected people with undetectable (<50 copies/mL) plasma HIV-1 RNA who had neurocognitive impairment and who had been on stable ART for at least 6 months prior to study entry. The purpose of this study was to evaluate if the addition of MVC and DTG to participants' existing ART regimens improved participants' neurocognitive performance.

Participants were randomly assigned to one of three arms. All participants remained on their existing ART regimens; they took their assigned study drugs in addition to their ART regimen. Study visits occurred at entry and Weeks 2, 4, 12, 24, 48, 72, and 96. Visits may have included physical examinations, blood collection, neurocognitive testing, pregnancy testing, and questionnaires. Some participants may have had an optional lumbar puncture procedure at study entry and Week 48. Participants returned for refills of study drugs on Weeks 36, 60, and 84.
