About this study

Official title: A Phase 1B Clinical Trial to Evaluate the Safety and Immunogenicity of Recombinant Adenoviral Subtype 35 (rAd35) and Subtype 5 (rAd5) HIV-1 Vaccines When Given as a Heterologous Prime-boost Regimen or as Boosts to a Recombinant DNA Vaccine in Healthy, Ad5-Naïve and Ad5-Exposed, Low Risk, HIV-1 Uninfected Adult Participants

This study will evaluate the safety and preliminary immune response to recombinant adenoviral serotype 35 and 5 HIV-1 vaccines in HIV-uninfected adults.

Read the detailed description

One of the more promising approaches in the development of a preventive HIV vaccine uses a DNA plasmid to prime the immune response to an adenoviral vector boost. This primary purpose of this study is to evaluate the safety, tolerability, and immune response to recombinant adenoviral serotype 35 (rAd35) and serotype 5 (rAD5) HIV-1 vaccines in Ad-5 naive and Ad-5 exposed HIV-uninfected adults.

This study will last approximately 12 months. Participants will include those who are both rAD5-naive and rAD5-exposed and will be stratified into one of four groups. Each group will consist of two arms, one interventional and one control. Participants in Groups 1, 2, and 3 will be rAD5-naive. Participants in Group 4 will be rAD5-exposed.

Participants in Group 1 will receive an injection of rAD35 vaccine or placebo at study entry and an injection of rAD5 vaccine or placebo at Month 6 with nine follow-up visits through Month 12. Participants in Groups 2, 3, and 4 will injections of DNA vaccinations or placebo at study entry and at Months 1 and 2, and an injection of rAD35 vaccine, rAD5 vaccine, or placebo at Month 6 with twelve follow-up visits though Month 12. A physical, questionnaire, and counseling will occur at all visits. Blood and urine collection will occur at most visits. A rectal swab will occur at selected visits. For females, a pregnancy test will occur at all visits.

Participants will be contacted for safety follow-ups after the injection every year for 5 years. Health and adverse events will be recorded. Participants will not need to return to the study clinic unless HIV confirmatory testing is needed.

What is being measured

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

  1. Local and systemic reactogenicity signs and symptoms, laboratory measures of safety, and adverse and expedited adverse events

    Measured: Throughout study

  2. Magnitude and frequency of immune responses between HIV-1 clade A env rAD35 and rAd5 vaccines when given as a boost after DNA vaccine

    Measured: At Week 4 following the fourth vaccination

  3. Magnitude and frequency of immune responses between clade A env rAD35 vaccine primed by Ad35 versus DNA

    Measured: At Week 4 following the last vaccination

  4. Magnitude and frequency of immune responses of HIV-1 clade A env rAD35 vaccine when given as a boost

    Measured: At Week 4 following the fourth vaccination

Secondary outcomes (1)
  1. Immunogenicity of HIV-1 clade A env rAD35 vaccine given as a prime

    Measured: At Week 4 following the first vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing DNA Vaccine, rAd35 and rAd5 in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 10 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 11 inclusion and 29 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 14 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 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. 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?

Local and systemic reactogenicity signs and symptoms, laboratory measures of safety, and adverse and expedited adverse events (time frame: Throughout study). The study lists 4 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 NCT00801697, which also lists 4 linked publications.

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 2021.
