What You Need to Know Before You Apply

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.

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 2 3 4 5}

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. ^{4 6 7 8 9}

Are You a Good Fit for This Trial?

Adults aged 18-70 with HIV, on stable ART for at least 48 weeks, and undetectable viral load. They must understand the study, consent to it, be willing to restart ART if needed, and adhere to protocol restrictions. Excluded are those with acute illness or certain medical conditions like advanced liver disease or history of significant heart issues.

Inclusion Criteria

I have been on ART for at least 48 weeks.

Each potential study participant must pass the Test of Understanding (TOU) after reading the informed consent and receiving detailed information on the study

Exclusion Criteria

I have not had a severe HIV-related illness in the last 10 years.

Pregnant, breastfeeding, or planning to become pregnant while enrolled in the study

I cannot have shots, IV lines, or blood taken due to medical reasons.

What Are the Treatments Tested in This Trial?

Interventions

• Ad26.Mos4.HIV
• MVA-BN-HIV
• PGDM1400
• PGT121
• VRC07-523LS

Trial Overview The trial is testing a vaccine regimen (Ad26.Mos4.HIV prime and MVA-BN-HIV boost) combined with antibodies (PGT121, PGDM1400, VRC07-523LS) in HIV-infected adults on ART. It's a Phase 1/2a study assessing safety, tolerability, immune response and preliminary effectiveness.

How Is the Trial Designed?

Group I: Ad26.Mos4.HIV, MVA-BN-HIV Vaccine Plus PGT121, PGDM1400, and VRC07-523LS bNAbs Experimental Treatment 5 Interventions

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.
