Official title: A First-in-human Phase 1 Clinical Trial to Evaluate the Safety, Tolerability, and Immunogenicity of 16055 NFL Delta Gly4 Env Protein Trimer and Trimer 4571 Combined With 3M-052-AF + Alum Adjuvant and Ad4-Env145NFL Viral Particles as Heterologous Prime-boost Regimens in Adult Participants Without HIV

The goal of this clinical trial is to test 16055 NFL delta Gly4 Env protein trimer and Trimer 4571 combined with 3M-052-AF + Alum adjuvant and Ad4-Env145NFL viral particles as heterologous prime-boost regimens in adult participants without HIV.

The main question[s] it aims to answer are:

  • Are these vaccine regimens safe and well tolerated?
  • Are the prime-boost vaccine regimens that include Ad4-Env145NFL and Trimer 4571 as heterologous boosts going contribute to the development of B-cell and antibody responses?

Participants will attend scheduled study visits to receive their vaccine and will record symptoms on a daily eDiary.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 16055 NFL delta Gly4 trimer, Trimer 4571 and Ad4-Env145NFL, 5 x 108 viral particles (vp) in people with HIV, run by National Institute of Allergy and Infectious Diseases (NIAID) at 6 sites in United States.

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 36 inclusion and 39 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: under way, not looking for participants, as of the sponsor's last update on 5 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in 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. 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Local reactogenicity signs and symptoms (time frame: 2 weeks following any injection). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06332339.

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 5 Nov 2024.
