Trial summary

The potential HIV vaccine has two components: a protein immunogen based on the coat protein of HIV; and an adjuvant which enhances the vaccinee's response to the immunogen. The immunogen is CN54gp140, and the adjuvant is glucopyranosyl lipid adjuvant - aqueous formulation (GLA-AF). Read more about this study

About this study

Official title: A Phase 1 Open-Labelled Trial to Evaluate the Safety and Immunogenicity of CN54gp140 in HIV-Uninfected, Healthy Volunteers

The potential HIV vaccine has two components: a protein immunogen based on the coat protein of HIV; and an adjuvant which enhances the vaccinee's response to the immunogen. The immunogen is CN54gp140, and the adjuvant is glucopyranosyl lipid adjuvant - aqueous formulation (GLA-AF).

We wish to assess the vaccine's safety and immunogenicity (the nature of the immune response stimulated by the vaccine) when it is given in two different dose regimens:

Read more

Group A: vaccinations at Months 0, 1, 2 and 6; and Group B: vaccinations at Months 0, 1, 2 and 12.

Each dose will be an intramuscular injection of 100 micrograms of CN54gp140 mixed with 5 micrograms of GLA-AF.

We will recruit only healthy, HIV-uninfected men and women. We will assess the safety of the vaccine by monitoring the occurrence of adverse events in the participants. We will assess the immunogenicity of the vaccine by monitoring the immune response to the vaccine in blood and in genital mucosal secretion samples.

What is being measured

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

  1. Number of Participants With Moderate or Greater Reactogenicity (i.e., Solicited Adverse Events)

    Measured: 7 days

  2. Number of Participants With Moderate or Greater and/or Vaccine-related Unsolicited Adverse Events (AEs)

    Including safety laboratory (biochemical, haematological) parameters, from the day of each vaccination up to 28 days post each vaccination.

    Measured: 28 days

  3. Number of Participants With Vaccine Related Serious Adverse Events (SAEs) Collected Throughout the Study Period

    Measured: 13 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CN54gp140 mixed with GLA-AF in people with HIV Infections, 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 10 inclusion and 19 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 7 Nov 2019. 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?

Yes. Results are posted in the registry (first posted 7 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 Moderate or Greater Reactogenicity (i.e., Solicited Adverse Events) (time frame: 7 days). The study lists 3 primary outcomes in all. 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 NCT01966900, which also lists 2 linked publications.

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 7 Nov 2019.
