Trial summary

A vaccine to prevent infection with the Human Immunodeficiency Virus (HIV) is urgently needed. Worldwide, most HIV infections occur through sex between a man and woman. The vaccine in this study consists of a protein from HIV that has been synthetically produced and linked to a protein that boosts immune responses. Read more about this study

About this study

Official title: Phase I Clinical Trial in Healthy Female Volunteers of Reactogenicity and Immunogenicity of Three Cervico-vaginal Topical Immunisations With a Fixed Dose of HIV CN54gp140 Glycoprotein-hsp70 Conjugate Vaccine

A vaccine to prevent infection with the Human Immunodeficiency Virus (HIV) is urgently needed. Worldwide, most HIV infections occur through sex between a man and woman. The vaccine in this study consists of a protein from HIV that has been synthetically produced and linked to a protein that boosts immune responses. It has not been tested in humans before, but it is expected (from animal studies) that direct application into the female genital tract (via the vagina) as liquid drops, will provoke immune protection at the site of HIV infection. This is less applicable to men, therefore only healthy, HIV negative women will be recruited. The investigators will recruit at one site, which is a university vaccine research centre with experience of running similar trials. The study will last 24 weeks during which subjects will have blood samples taken on six visits, and three immunisations over 12 weeks in which 1 millilitres of vaccine is placed into the vaginal by inserting a small plastic syringe. The purpose of this initial small study is to monitor safety of the vaccine and to determine whether it is appropriate to continue into future, larger studies in which the immune response to the vaccine is measured.

Read the detailed description

This hypothesis-generating, first-in-human, Phase 1 study will be conducted according to the Standard Operating Procedures (SOPs) of St George's. The purpose of the study is to determine the immediate safety and reactogenicity of the vaccine, to guide future larger Phase 1/2 studies of safety and efficacy.

Eight subjects will be included to receive 3 cervico-vaginal topical applications of 100µg of CN54gp140-hsp70 conjugate vaccine in 1.0 mL physiological buffer, administered as topical intra-vaginal drops on day 0, and at 4 and 12 weeks after the first immunisation. The study will consist of 1 pre-study screening visit, 3 immunisation visits, and 2 follow-up visits over a total period of 20 weeks. Subjects will be recruited as one cohort in two groups of four. The dose of antigens and immunisation schedule has been selected based on pre-clinical and clinical experience with the same HIV envelope protein.

Each subject's medical history (including past and present illnesses, current medications, family medical history) will be formally assessed and recorded at screening. Volunteers' age, gender, height, weight and ethnic origin will be recorded. A full physical examination will be conducted by a registered medical practitioner at screening and the final study visit. Regular assessments of vital signs (pulse, blood pressure, temperature) will be made on all visits.

Diary cards, investigator-prompted recall of events, laboratory tests (haematology, biochemistry) and direct visualisation of immunisation site will be used to identify Adverse Events. Frequency of vaccine-related Adverse Events is the Primary Study Endpoint.

Before and after each immunisation visit (0, 4 and 12 weeks) blood samples will be obtained for collection of serum and for separation of PBMCs for cellular assays. At each time point, vaginal and cervical secretions will be taken. All immunology assays are exploratory and are not study endpoints. HIV serology and DNA detection will be repeated at the final visit to detect subjects who may have contracted HIV infection during the study period, and who may therefore have developed antibody and T-cell responses due to the HIV infection that would interfere with exploratory immunology assays.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CN54gp140 glycoprotein-hsp70 conjugate vaccine in people with HIV Infections, run by St George's, University of 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 6 inclusion and 17 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 5 Dec 2012. 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 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?

Frequency of local immunisation site vaccine-related Adverse Events (time frame: 20 weeks). 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 NCT01285141, 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 5 Dec 2012.
