About this study

Official title: A Randomized, Placebo-controlled, Phase I/II Clinical Trial to Evaluate the Safety, Immunogenicity, and Impact on Virological Control of the Investigational RNA-based Vaccine BNT168 in Adults Living With or Without HIV

This study will test a new ribonucleic acid (RNA)-based vaccine called BNT168 in adults living both with and without human immunodeficiency virus (HIV), to see how safe it is, how well it triggers the body's immune response and how it affects the amount of virus in the body.

Read the detailed description

Currently, this study consists of one part (Part A) which will be a Phase I, randomized, placebo-controlled, double-blind, first-in-human (FIH), dose escalation with an initial proof-of-principle component. Depending on the safety and immunogenicity data generated in this study, the Phase II part of this study and/or some of the cohorts may not be initiated or may be terminated earlier by sponsor decision. In this study:

  • Three cohorts of people living without HIV (PLWOH) will be randomized in a 5:1 ratio to receive BNT168 or placebo. Participants in these cohorts will receive 3 injections. BNT168 will be evaluated for safety, reactogenicity, and vaccine-induced immunogenicity in this population.
  • Two cohorts of people living with HIV (PLWH), will be randomized in a 2:1 ratio to receive BNT168 or placebo. Participants in these cohorts will receive 4 injections. BNT168 will be evaluated in PLWH on combination antiretroviral therapy (cART) for safety, reactogenicity, and vaccine-induced immunogenicity in this population. An initial proof-of-principle assessment will be conducted in PLWH who undergo analytical treatment interruption (ATI) to evaluate viral kinetics after investigational medicinal product (IMP) administration. After the ATI period, cART will be restarted as per protocol.

For PLWOH, there will be an ~1-month screening period, ~2-month treatment period and an ~6-month follow-up period. The planned study duration per participant is ~9 months.

For PLWH, there will be an ~1-month screening period, ~6-month treatment period and an ~6-month follow-up period. The planned study duration per participant is maximum ~13 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BNT168 in people with HIV -1 Infection, run by BioNTech SE at 4 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 21 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 14 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in South Africa, United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact BioNTech clinical trials patient information (+49 6131 9084 ext. 0, patients@biontech.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Occurrence of at least one adverse event (time frame: From dosing through 28 days after each IMP dose). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Oct 2026.
