  • Evidence of any systemic disease or any acute or chronic illness that may interfere with the evaluation of the safety of the vaccine.
  • History or laboratory evidence of any possible immunodeficiency state.
Show all 16Show fewer
  • History of allergic disease or reactions likely to be exacerbated by any component of the study vaccine.
  • Received any non-BCG TB vaccine previously.
  • For female subjects: Currently pregnant, lactating/nursing, or a positive urine HCG.

About this study

Official title: A Phase I, Double-blind, Randomized, Placebo-controlled, Study to Evaluate the Safety and Immunogenicity of AERAS-456 in HIV Negative Adults Successfully Treated for Drug-susceptible Pulmonary Tuberculosis

This is a Phase I, double-blind, randomized, placebo-controlled safety and immunogenicity study in adults who have recently been successfully treated for drug-susceptible pulmonary Tuberculosis (TB). The safety and immunogenicity profile of escalating doses of AERAS-456 in HIV-negative subjects recently treated for drug-susceptible pulmonary TB will be investigated. The study will be conducted at three sites in South Africa.

Read the detailed description

This study will be the first evaluation of AERAS-456 in subjects who have completed a full course of treatment prescribed for pulmonary TB. Subjects will begin screening for study participation when they have completed 4 calendar months of TB treatment. Subjects meeting the inclusion/exclusion criteria will be randomized within a study group in a 3:1 ratio (N=18 AERAS-456; N=6 placebo) to receive two 0.5 mL intramuscular injections of AERAS-456 or placebo eight weeks apart, on Study Day 0 and Study Day 56.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • H56:IC31Biological

    Also called AERAS-456

    H56:IC31 contains a fusion protein (referred to as H56 antigen, or H56) of 3 mycobacterial antigens (the early secreted antigens Ag85B and ESAT-6, and the latency antigen Rv2660c).

  • PlaceboBiological

    The placebo consists of 10mM Tris and 169 mM NaCl pH 7.4.

What is being measured

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

  1. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Unsolicited AEs: 28 days after each vaccination Solicited AEs: 7 days after each vaccination SAEs: through Day 420 Adverse events of special interest: through Day 420

    Measured: Day 0 to Day 420

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing H56:IC31 in people with Tuberculosis, run by Aeras at 3 sites in South Africa.

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 16 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 30 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in South Africa. 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?

Yes. Results are posted in the registry (first posted 18 Nov 2019). 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?

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) (time frame: Day 0 to Day 420). 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 NCT02375698, 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 30 Jul 2024.
