About this study

Official title: Safety and Immunogenicity of Heterologous Prime-boost With the Candidate Malaria Vaccines AdCh63 ME-TRAP and MVA ME-TRAP in Healthy Adults in a Malaria Endemic Area

The purpose of this trial is to assess the safety and immunogenicity of AdCh63 ME-TRAP and MVA ME-TRAP candidate vaccines in healthy adult volunteers in a malaria endemic region. The regime proposed in this trial has protected non-immune volunteers against sporozoite challenge in clinical trials performed by Oxford, and so may be protective against naturally acquired infection in Kenya.The study population will comprise 30 healthy adult males aged 18-50.

The investigators do not propose to include a placebo group. At this stage the investigators objective is to describe the safety profile in a small number of individuals, and the confidence intervals for the proportion of individuals with a particular event would be too wide for meaningful comparison with a placebo group. Immunogenicity will be judged by comparison with baseline.

What is being measured

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

  1. Safety and reactogenicity of AdCh63 ME-TRAP followed by MVA ME-TRAP in adults in Kenya.

    To assess safety and reactogenicity of AdCh63 ME-TRAP followed by MVA ME-TRAP in adults in Kenya by recording local and systemic solicited and unsolicited adverse events

    Measured: Participants will be followed for the duration of the study, an expected average of 12 months

Secondary outcomes (2)
  1. Immunogenicity of vaccines

    To evaluate the immunogenicity of AdCh63 ME-TRAP followed by MVA ME-TRAP in adults in Kenya by assessing induced antibody and T cell response to the vaccine insert.

    Measured: Participants will be followed for the duration of the study, an expected average of 12 months

  2. Immunogenicity of Vaccines

    To compare the use of intra-muscular and intra-dermal MVA ME-TRAP

    Measured: Participants will be followed for the duration of the study, an expected average of 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AdCh63 ME-TRAP followed by MVA ME-TRAP in people with Malaria, run by University of Oxford at 1 site in Kenya.

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 2 inclusion and 12 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 3 Oct 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 Kenya. 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 and reactogenicity of AdCh63 ME-TRAP followed by MVA ME-TRAP in adults in Kenya. (time frame: Participants will be followed for the duration of the study, an expected average of 12 months). 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 NCT01379430, 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 3 Oct 2012.
