About this study

Official title: A Phase I Study to Evaluate the Safety and Immunogenicity of Simultaneous Prime-Boost Immunisations With Candidate HCV and HIV-1 Vaccines, AdCh3NSmut1 / ChAdV63.HIVconsv and MVA-NSmut / MVA.HIVconsv, in Healthy Volunteers

This study is aimed at assessing the safety of candidate Hepatitis C vaccines AdCh3NSmut/MVA-NSmut and HIV vaccines ChAdV63.HIVconsv/MVA.HIVconsv when administered separately or in combination to healthy volunteers. The study also aims to assess the cellular immune response generated by these vaccines when administered as mentioned above.

Read the detailed description

Hepatitis C and HIV are both widespread pathogens. By the end of 2010, there were 2.3 million people in Europe living with HIV, over half of whom were coinfected with the Hepatitis C virus (HCV). Although vaccination is the optimal method of preventing infection, it has proved extremely difficult to develop an effective vaccine against HIV and HCV due to the enormous variation in strains around the world. This is caused by the extraordinary ability of the viruses to change their genetic material.

Researchers at the University of Oxford have developed novel candidate vaccines against HIV ('HIV.consv') and HCV ('NSmut'). These vaccines have been inserted into the carrier viruses Chimpanzee Adenovirus (ChAd or AdCh) and modified vaccinia virus Ankara (MVA), both of which have excellent safety records. The aim of this study is to test for the first time the response of the immune system when vaccines to both HIV and HCV are given together.

During this study, 32 healthy adults aged 18 to 50 years will be recruited into one of three groups to receive either two or four intramuscular injections over a period of two months. All participants will be followed up for a further six months (12 visits in total).

What is being measured

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

  1. Safety of administering simultaneous HCV/HIV-1 prime-boost vaccinations, as measured by the proportion of volunteers who develop a grade 3 or 4 local or systemic reaction

    Proportion of volunteers who develop a grade 3 or 4 local reaction Proportion of volunteers who develop a grade 3 or 4 systemic reaction

    Measured: Actively collected throughout the study until 6 months after the last vaccination

Secondary outcomes (1)
  1. Cellular immune response generated by simultaneous HCV/HIV-1 prime-boost vaccinations, as determined by analysing changes in the magnitude or quality of HCV and HIV-1-specific cellular immune responses.

    Immunogenicity determined by analysing changes from baseline in the magnitude or quality of HCV and HIV-1-specific cellular immune responses. These will be detected using several standardised assays. The primary outcome measure for immunogenicity will be the development of T cell responses to HCV and HIV-1 epitopes, as determined by IFN-ɣ ELISpot assay. In addition, several exploratory immunology assays (including but not limited to intracellular cytokine staining, phenotype, viral suppression in vitro) will be developed and used.

    Measured: Actively collected throughout the study until 6 months after the last vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AdCh3NSmut1, MVA-NSmut and ChAdV63.HIVconsv in people with Hepatitis C Infection and HIV Infection, run by University of Oxford 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 12 inclusion and 24 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 Oct 2018. 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?

Safety of administering simultaneous HCV/HIV-1 prime-boost vaccinations, as measured by the proportion of volunteers who develop a grade 3 or 4 local or systemic reaction (time frame: Actively collected throughout the study until 6 months after the last 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 NCT02362217, 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 11 Oct 2018.
