About this study

Official title: A Randomised, Open Labelled, Phase I, Safety, Toxicity, and Exploratory Immunogenicity Evaluation of Therapeutic Immunisation +/- IL-2, GM-CSF and Growth Hormone in HIV-1 Infected Subjects Receiving Highly Active Anti-retroviral Therapy

For several years there has been interest in why some people with HIV-1 progress more slowly to disease and have longer survival without Highly Active Antiretroviral Therapy (HAART) than others. The investigators and others have identified a few HIV positive individuals who can control their viral load for many years without HAART, these rare individuals do not lose their HIV-1-specific cellular immune responses, which are very important for controlling viral load. This group is referred to as long-term non-progressors (LTNP). Unlike LTNP the majority of HIV-1 infected individuals are chronic progressors (CP) who do not make effective HIV-1-specific cellular immune responses, even when on HAART. We propose to use a novel DNA vaccine boosted with immune based therapy (cytokines and hormones) to try to regenerate the missing HIV-1-specific cellular immune responses to make chronically infected HIV-1+ persons more like LTNP.

By injecting this novel DNA vaccine and immune based therapy into the people who are already infected with HIV-1, the immune system may be stimulated to mount a greater immune response not only to the vaccines but also to real HIV-1 particles and HIV-1-infected cells.

Read the detailed description

This will be a randomised, Phase I, open label comparative study running for 52 weeks (2 screen visits 2 weeks apart followed by 48 weeks of study). 50 patients will be screened in the initial phase of which 30 clade B infected individuals will be randomised into the study, which will consist of 3 arms:

Arm 1 will ascertain vaccine safety and toxicity in the presence of cytokine/hormone therapy.

Arm 2 will identify vaccine safety and toxicity.

Arm 3 will indicate safety and toxicity of cytokine/hormone therapy.

The target patients are chronically HIV-1 clade B infected persons who will have had a nadir CD4 T-cell count of >200 cells/ul blood before they started ART. The current CD4 T-cell count should be >400 cells/ul blood. Patients may have received ART for any length of time, but currently should be receiving NNRTI or boosted-PI based HAART, and have a viral load below the level of detection (50 copies/ml plasma). Patients will be bled on two occasions before commencing IBT regimens, in order to establish baselines, and then at regular intervals thereafter (weeks 0,1,2,4,6,8,12,16,24 and 48).

The treatment regimens are consistent with previous findings in animal models which suggest that administration of IL-2 during the antigen-specific T-cell contraction phase of an immune response (between 8 and 15 days post-vaccination) may preserve and lengthen clinically relevant responses. Furthermore studies in man have demonstrated that IL-2 administered before immunisation in ART-treated HIV-1-infected patients does not increase specific lymphoproliferation of T cells.

Recent preliminary studies in HIV-1-infected individuals using tetanus vaccines the investigators have shown that IL-2 administered after immunisation may be more effective at inducing sustained tetanus-specific responses than IL-2 administered before immunisation or together with immunisation. The dosages used in this study are based on those used in previous pilot studies of the administration of IL-2 + GM-CSF and rhGH and at these levels the drugs have been shown to have both positive effect on the immune response and demonstrated clinical benefit whilst being at a level which is safe and well tolerated in HIV-1 positive individuals. The dosage of the vaccine was based on a previous study where a dosage of this level has been shown to induce an immune response although this response was transient. In summary the investigators aim to increase the survival of vaccine responses through the administration of cytokines/hormones and boost memory responses with further rounds of immunisation.

    Measured: Weekly

Secondary outcomes (1)
  1. The secondary immunological outcomes will be percentage change from baseline to study time point in defined cellular immune responses.

    Measured: weekly

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GTU-MultiHIV B clade vaccine1mg, Interleukin-2 and GM-CSF in people with HIV-1 Infection, run by Imperial College London 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 9 inclusion and 10 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: stopped early, as of the sponsor's last update on 4 Sep 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. 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 was stopped early (reason given: Data from the 12 patients recruited has now been analysed, and it has been determined that it is sufficient to meet the study objectives.). Results are not available in the source record.

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?

The primary outcome will be analysis of safety and toxicity data in relation to grade 3 or above laboratory or clinical serious adverse event (SAE) which can be attributed to the treatments given (time frame: Weekly). 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 NCT01130376, 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 4 Sep 2013.
