Clinical Trial of Gammora® Plus Antiretroviral Treatment for HIV

Active Not RecruitingPhase 2

Sponsor: Federal University of São Paulo

Conditions: HIV Seropositivity

Interventions: Gammora®

Countries: Brazil

The goal of this phase II, open-label, randomized, controlled clinical trial is to evaluate the impact of Gammora®, a 16-mer HIV integrase-derived peptide associated with a boosted darunavir antiretroviral regimen compared Gammora® arm) to a boosted darunavir antiretroviral regimen only (control arm) in the estimated HIV reservoir among antiretroviral naïve people living with HIV. The main questions it aims to answer are: 1. Will the proviral (total) HIV-1 DNA decrease rapidly in the Gammora® arm compared to the control arm? 2. Will the apoptosis markers evaluated in the CD4+ T cell by flow cytometry increase in the Gammora® arm compared to the control arm? Forty antiretroviral naïve viremic people with HIV with CD4+ T cell counts \>350 cells/mL will be randomized to receive 20 mg of Gammora® in 2mL SC solution plus Tenofovir/3TC and Darunavir 800mg+Ritonavir 100mg (Gammora® arm) or antiretroviral only (control arm). In the Gammora® arm, participants had a 2-week Gammora® monotherapy lead-in period with Gammora® given daily before antiretroviral treatment is started, followed by 12 weeks of antiretroviral therapy plus Gammora® given every other day. The first two weeks of the trial (lead-in period for the Gammora® arm) were labeled w-2 and w-1 for both groups, and blood samples were collected for both groups. w0 denotes the week ART was started in both arms.
