About this study

Official title: A Phase II, Double-blind, Randomized, Placebo-controlled, Multicenter Study to Evaluate the Safety and Immunogenicity of AERAS-402 in BCG-vaccinated, HIV-uninfected Infants Without Evidence of Tuberculosis

AERAS-402 will be given to infants of at least 16 weeks of age who have already been vaccinated with BCG to determine if AERAS-402 will increase protection of infants to tuberculosis.

Read the detailed description

The only currently available tuberculosis vaccine, bacillus Calmette-Guérin (BCG), is estimated to reduce the risk of tuberculosis (TB) in children by up to 70-80%, but protection is incomplete. Efforts to increase TB protection in children include new vaccines for primary immunizations as well as combinations of vaccines given as primary and boosting vaccinations.

AERAS 402 is a live recombinant serotype 35 replication deficient adenovirus vector expressing a fusion protein of three Mycobacterium tuberculosis (Mtb) antigens (Ag85A, Ag85B and TB10.4). It presents Mtb antigens in the setting of a new, live, replication-deficient adenovirus vaccine that may increase T cell-mediated immunity and thus protection from tuberculosis. AERAS-402 appears safe and immunogenic in adults. Since BCG-vaccinated infants are the population for which AERAS-402 might be indicated, AERAS-402 will be administered to infants of at least 16 weeks of age who have already been vaccinated with BCG. This is the first Phase II study of AERAS-402 in infants.

What is being measured

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

  1. Adverse Events Collected Per Subject

    Adverse Events (AEs) are recorded for 28 days post vaccination Serious Adverse Events (SAEs) are recorded for the entire study period to assess the safety profile

    Measured: Up to 24 months post vaccination

Secondary outcomes (4)
  1. Percentage of Cells Expressing Various Cytokines Will be Measured by Intracellular Cytokine Staining (ICS) in All Subjects

    To evaluate the immunogenicity of AERAS-402 compared to controls, flow cytometric ICS of CD4 and CD8 T cells producing any of three cytokines (IFN-γ, TNF-α, and/or IL-2) alone or in combination after stimulation with a peptide pool of mycobacterial peptides. Dimethylsulfoxide (DMSO) subtracted responses are presented.

    Measured: 28 days post last vaccination

  2. Interferon-gamma (IFN-gamma) Enzyme-linked Immunospot (ELISpot) Response: Spot Forming Units/10^6 PBMC According to ELISpot Assay

    To evaluate the immunogenicity of AERAS-402 compared to controls. ELISpot assay of specific T cell responses after stimulation with a peptide pool of mycobacterial peptides. Values presented have been corrected for background readings.

    Measured: 28 days post last vaccination

  3. Antigen-specific Antibody Response - Mean Optical Density (Mean OD)

    To evaluate the immunogenicity of AERAS-402 compared to controls by ELISA Assay for Antigen-specific Antibody Response. Median responses of individual Mean OD (absorbance at 450nm) by study group is presented. Higher OD values suggests the presence of antibody to each of the Mtb antigens (Ag85A, Ag85B and TB10.4).

    Measured: 28 day post last vaccination

  4. Percentage of Subjects Converting From a Negative QuantiFERON Test (QFT) to Positive QFT After Vaccination

    To evaluate the proportion of on-study QuantiFERON conversions from negative to positive in infants that received AERAS-402 compared to controls. A QFT value of on >= 0.35IU/mL was considered positive for this study.

    Measured: up to 24 months post vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing AERAS-402 1.5 x 10^10 vp, AERAS-402 3.0 x 10^10 vp and AERAS-402 1.0 x 10^11 vp in people with Tuberculosis, run by Aeras at 7 sites in 3 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 8 inclusion and 13 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 8 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Kenya, South Africa, Mozambique. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Aug 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Adverse Events Collected Per Subject (time frame: Up to 24 months post vaccination). 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 NCT01198366, which also lists 1 linked publication.

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 8 May 2017.
