About this study

Official title: Phase I Randomized, Double-Blind, Placebo-Controlled Trial to Evaluate the Safety and Immunogenicity of TBC-M4 (MVA Based HIV Vaccine) Alone or in a Prime-Boost Regimen With ADVAX, DNA HIV Vaccine

This trial will study a prime-boost vaccine approach designed mainly to induce cell-mediated immune (CTL) responses.

Read the detailed description

Two vaccine candidates will be used in two different prime-boost regimens: ADVAX (DNA) + TBC-M4 (MVA) and TBC-M4 (MVA) alone. Both these vaccines have already been tested in humans and both were found to be well tolerated and immunogenic. Approximately 32 volunteers (24 vaccine /8 placebo recipients) will be included in the study.

What participants receive

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

  • ADVAXBiological

    Receive 4mg ADVAX at Months 0, 1, and 2 (Biojector), and receive boost of 5x10^7 pfu TBC-M4 (IM)

  • TBC-M4Biological

    Receive 5x10^7 pfu TBC-M4 (IM) at Months 0, 1, and 6.

  • PlaceboOther

    Group A (n=4) will receive the ADVAX placebo (formulation buffer) via Biojector.

    Group B (n=4) will receive the TBC-M4 placebo (formulation buffer) via IM.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ADVAX and TBC-M4 in people with HIV Infections, run by International AIDS Vaccine Initiative at 1 site in United Kingdom.

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 7 inclusion and 56 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 11 Feb 2013. 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 Kingdom. 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?

Safety of TBC-M4 alone or in a prime-boost regimen with ADVAX (time frame: 12 months). 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 11 Feb 2013.
