Trial Summary

What is the purpose of this trial?

A multicenter, randomized, parallel-group, placebo-controlled, double-blind, Phase 1/2a clinical study to investigate the safety, tolerability, immunogenicity and exploratory efficacy of a vaccine regimen consisting of an Ad26.Mos4.HIV prime and a boost with Modified Vaccinia Ankara (MVA)-BN-HIV in combination with broadly neutralizing antibodies (bNAb) PGT121, PGDM1400, and VRC07-523LS in human immunodeficiency virus type 1 (HIV-1)-infected study participants on suppressive anti-retroviral therapy (ART).

Will I have to stop taking my current medications?

The trial requires participants to be on suppressive anti-retroviral therapy (ART) for at least 48 weeks before screening and to continue it during the study. However, nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin must be stopped for 5 days before and after planned leukapheresis. Other medications are not specifically mentioned, so it's best to discuss with the study team.

What data supports the effectiveness of the HIV vaccine treatment Ad26.Mos4.HIV, MVA-BN-HIV, PGDM1400, PGT121, VRC07-523LS, VRC07-523LS?

Research on similar treatments, like the MVA-B vaccine, shows it is safe and can trigger strong immune responses, including the production of antibodies and T cells that target HIV. This suggests that the components in the new treatment might also be effective in stimulating the body's defenses against HIV. ^{1 2 3 4 5}

Is the HIV vaccine safe for humans?

The HIV vaccine candidates, including MVA-B and MVA-BN, have been tested in various trials and found to be generally safe in humans, with no serious adverse events reported. Common side effects were mild, such as injection site pain, and the vaccines were well tolerated even in people with HIV. ^{1 6 7 8 9}

Participants will receive Ad26.Mos4.HIV vaccine at week 0 and MVA-BN-HIV vaccine at week 12. The bNAbs PGT121, PGDM1400, and VRC07-523LS will be administered at week 24, and the bNAbs PGT121 and PGDM1400 will be administered at week 28.

Group II: Ad26.Mos4.HIV, MVA-BN-HIV Vaccine Plus Placebo Active Control 2 Interventions

Participants will receive Ad26.Mos4.HIV vaccine at week 0 and MVA-BN-HIV vaccine at week 12. Placebo will be administered at week 24, and at week 28.

Group III: Placebo Plus PGT121, PGDM1400, and VRC07-523LS bNAbs Active Control 3 Interventions

Participants will receive Placebo at week 0 and 12. The bNAbs PGT121, PGDM1400, and VRC07-523LS will be administered at week 24, and the bNAbs PGT121 and PGDM1400 will be administered at week 28.
