About this study

Official title: A Phase II, Proof of Concept, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Protective Efficacy Against TB Disease, Safety, and Immunogenicity of MVA85A/AERAS-485 in Healthy, HIV-infected Adults

This is a phase II, proof of concept, randomized, double-blind, placebo-controlled study to evaluate the protective efficacy against TB disease, safety, and immunogenicity of MVA85A/AERAS-485 in healthy, HIV-infected adults.

This study consists of 650 adults subjects (ages 18-50 years of age inclusive) who will receive study vaccine or placebo at Study Day 0 and again 6-9 months later. Samples for real-time evaluation of immunogenicity were to be collected from 70 subjects (immunogenicity analysis set).

Read the detailed description

This Phase II multi-country trial was conducted as a randomized, double-blind, placebo-controlled trial in 650 HIV-positive adults with no evidence of active TB disease. Subjects were stratified at the time of randomization by whether or not they were receiving anti-retroviral therapy (ART) and then randomized in a ratio of 1:1 to receive either MVA85A/AERAS-485 at 1 x 10^8 plaque forming units (pfu) or placebo (Candin). Randomization of each group was capped so that at least 50% of the subjects randomized were receiving ART at randomization. Subjects were to receive an intradermal injection of MVA85A/AERAS-485 or placebo on Study Day 0, followed 6-9 months later by a booster injection of MVA85A/AERAS-485 or placebo. The minimum follow-up period for each subject was 6 months after their last vaccination, during which subjects were followed for safety, clinical signs and symptoms of TB, and immunogenicity. All subjects were to continue to be followed every 3 months until the last subject enrolled had been followed for 6 months after their last vaccination.

What is being measured

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

    Immunogenicity of MVA85A/AERAS-485 compared to placebo as described by the ex vivo interferon (IFN)-γ enzyme linked immunospot (ELISpot).

    Measured: 28 days post second vaccination.

  7. Immunogenicity of MVA85A/AERAS-485 Compared to Placebo as Described by Flow Cytometric Intracellular Cytokine Staining (ICS) of CD4+ and CD8+ T Cells After Stimulation With a Peptide Pool of Mycobacterial Antigens.

    The antigen-specific negative control-subtracted response for any cytokine (Interferon gamma [INFγ] , Interleukin 2 [IL2], Interleukin 17 [IL17] and tumor necrosis factor [TNF]).

    Measured: 7 days post second vaccination.

  8. QuantiFERON (QFN) Conversion Rate in MVA85A/AERAS-485 Recipients Compared to Control Subjects Without a Diagnosis of Tuberculosis During the Trial.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MVA85A/AERAS-485 in people with Tuberculosis and HIV Infections, run by Aeras at 2 sites in 2 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 10 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 24 May 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Senegal, 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 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 26 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?

Percentage of Participants With Adverse Events (time frame: Adverse Events (AEs) are recorded for 28 days post vaccination, Serious Adverse Events (SAEs) for at least 6 months post second 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 NCT01151189, 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 24 May 2016.
