About this study

24 healthy male and female volunteers who are at low risk of HIV infection and entered into the RISVAC02 study and were randomly allocated to receive 3 intramuscular injections of MVA-B at weeks 0, 4 and 16 will receive a boosting dose 4 years thereafter.

Participants will attend one of two clinical centres on at least 5 occasions over 16 weeks. These visits will comprise:

  • Screening
  • Trial entry and boosting immunisation
  • Early follow-up after immunisation
  • Follow-up x 2 including the final visit Participants will have blood and urine collected, and receive 1 immunisation. They will be counselled prior to and following a HIV test, and given health education on prevention of sexually transmitted infections including HIV. T

The two centres which participate are:

  • Hospital Clinic, Barcelona and
  • Hospital Gregorio Marañón, Madrid The primary objective is to explore the safety and immunogenicity of MVA-B.

What is being measured

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

  1. Local adverse event

    Grade 3 or above local adverse event (pain, cutaneous reactions including induration)

    Measured: 12 weeks

  2. Grade 3 or above systemic adverse event

    Grade 3 or above systemic adverse event (temperature, chills, headache, nausea, vomiting, malaise, and myalgia)

    Measured: 12 weeks

  3. Grade 3 or above other clinical or laboratory adverse event

    Grade 3 or above other clinical or laboratory adverse event confirmed at examination or on repeat testing respectively

    Measured: 12 weeks

  4. Event attributable to vaccine leading to discontinuation

    Any event attributable to vaccine leading to discontinuation of the immunisation regimen

    Measured: 12 weeks

  5. Primary immunogenicity parameters

    The primary immunogenicity parameters will be quantitative or present/absent, and are cellular responses - CD8/CD4+ T cell responses (ELISPOT) at week 2, 4 and 12 following the immunisations

    Measured: 12 weeks

Secondary outcomes (3)
  1. All grade 1 and 2 adverse events

    Measured: 28 days of vaccination

  2. Antibody responses

    • binding titration to the construct MVAB
    • binding titration to and neutralisation of vaccinia

    Measured: 12 weeks

  3. cellular responses

    • CD8/CD4+ T cell responses (ELISPOT) at week 0
    • intracellular cytokine analysis at week 0, 2, 4 and 12

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Experimental in people with HIV Infections, run by Hospital Clinic of Barcelona at 2 sites in Spain.

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 11 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 21 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Spain. 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?

Local adverse event (time frame: 12 weeks). The study lists 5 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 NCT01923610, 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 21 Mar 2017.
