Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 60 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • Each participant must have documented Human immunodeficiency virus type1 (HIV-1) infection
  • Each participant must be on suppressive antiretroviral treatment (ART) for at least 48 weeks prior to randomization and on stable suppressive ART for at least 4 weeks prior to screening. Changes in antiretrovirals (ARVs) can be made for safety/tolerability reasons only until 4 weeks prior to screening
  • Each participant must have started ART outside of the acute or early phase of infection
  • Each participant must have a plasma HIV ribonucleic acid (RNA) less than (<) 50 copies/ milliliter (mL) at screening and at least one documented evidence of plasma HIV RNA <50 copies/mL after the last ART change. In case of ART change within the 48 weeks prior randomization, at least one additional more recent documented plasma HIV RNA <50 copies/mL is required. One blip of HIV RNA greater than (>)50 and <200 copies/mL within 24 weeks prior to screening is acceptable, provided that the 2 most recent (after last ART change, tested before and/or during screening) HIV RNA results are <50 copies/mL
  • Each participant must be medically stable as confirmed by medical history, physical examination, vital signs, 12-lead electrocardiogram (ECG), and clinical laboratory tests performed at screening

Who cannot join

  • Anyone who is pregnant, breastfeeding, or planning to become pregnant while enrolled in this study, or within 3 months after the last vaccination
  • Anyone with contraindication to intramuscular injections and blood draws example, bleeding disorders
  • Anyone with acute illness (this does not include minor illnesses such as diarrhea or mild upper respiratory tract infection) or temperature greater than or equal to (>=) 38.0ºC (degree centigrade) within 24 hours prior to the first dose of study vaccine; enrollment at a later date is permitted
  • Anyone with a history of malignancy within 5 years before screening (exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or malignancy, which is considered cured with minimal risk of recurrence)
  • Anyone with a history of an underlying clinically significant acute or uncontrolled chronic medical condition or physical examination findings for which, in the opinion of the investigator, participation would not be in the best interest of the participant (example, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments
  • Anyone with a history of Acquired Immunodeficiency Syndrome (AIDS)-defining illness according to Centers for Disease Control and prevention (CDC) criteria based on available medical history and assessed by the investigator as clinically relevant. A case summary for every participant with AIDS-defining illnesses assessed by the investigator as clinically irrelevant must be provided to the sponsor and Protocol Safety Review Team (PSRT), who will determine eligibility on a case-by-case basis prior to randomization

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Solicited Local Adverse Events (AEs) as a Measure of Safety and Tolerability

    Solicited local AEs: erythema, swelling/induration, and pain/tenderness will be assessed.

    Measured: 7 days post-vaccination (approximately up to 37 weeks)

  2. Percentage of Participants With Solicited Systemic AEs as a Measure of Safety and Tolerability

    Solicited systemic AEs: fever (temperature measurement), fatigue, headache, nausea, myalgia, and chills will be assessed.

    Measured: 7 days post-vaccination (approximately up to 37 weeks)

  3. Percentage of Participants With AEs as a Measure of Safety and Tolerability

    An AE is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.

    Measured: Approximately up to 96 weeks

Secondary outcomes (6)
  1. Total IgG and Subclass Specific Antibody Titer

    Total immunoglobulin G (IgG) and subclass (IgG1-4) specific antibody titers (binding antibody) to envelope (Env) proteins representing Clades A, B, and C, as well as Mosaic antigens.

    Measured: Up to post-vaccination follow-up period until Week 96

  2. Antibody Functionality Assessment by Antibody-dependent Cell-mediated Phagocytosis (ADCP)

    Antibody functionality assessment will be assessed by antibody-dependent cell-mediated phagocytosis (ADCP) assay.

    Measured: Up to post-vaccination follow-up period until Week 96

  3. Magnitude of T-cell Responses as Measured by Intracellular Cytokine Staining (ICS) Assay

    Intracellular cytokine staining (ICS) assays with Env, group-specific antigen (Gag), and/or polymerase (Pol)-peptide pools will be used to determine the magnitude of T-cell responses elicited.

    Measured: Up to post-vaccination follow-up period until Week 96

  4. Functionality of T-cell Responses as Measured by ICS Assay

    ICS assays with Env, Gag, and/or Pol-peptide pools will be used to determine the functionality of T-cell responses elicited.

    Measured: Up to post-vaccination follow-up period until Week 96

  5. Phenotype of T-cell Responses as Measured by ICS Assay

    ICS assays with Env, Gag, and/or Pol-peptide pools will be used to determine the phenotype of T-cell responses elicited.

    Measured: Up to post-vaccination follow-up period until Week 96

  6. Frequency of Epitope Recognition by Enzyme-Linked Immunospot (ELISPOT)

    Assays of peptide pool sets covering the Gag, Env or Pol will be evaluated by standard enzyme linked immunospot assay (ELISPOT).

    Measured: Up to post-vaccination follow-up period until Week 96

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ad26.Mos4.HIV, MVA-Mosaic and Clade C gp140 + Mosaic gp140 in people with Human Immunodeficiency Virus, run by Janssen Vaccines & Prevention B.V. at 1 site 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 5 inclusion and 10 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: finished, as of the sponsor's last update on 4 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Percentage of Participants With Solicited Local Adverse Events (AEs) as a Measure of Safety and Tolerability (time frame: 7 days post-vaccination (approximately up to 37 weeks)). The study lists 3 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 4 Feb 2025.
