About this study

Official title: A Phase Ia Study to Assess the Safety and Immunogenicity of New Malaria Vaccine Candidates ChAd63 CS Administered Alone and With MVA CS

This is an open label phase I study, to assess the safety of a novel malaria vaccine, AdCh63 CS, simian adenovirus encoding Plasmodium falciparum liver stage antigen, Circumsporozoite protein. All volunteers recruited will be healthy adults. They will be primed with various doses of AdCh63 CS administered intramuscularly. Some of the volunteers will receive a booster vaccination with MVA CS administered via intramuscular route. Safety data will be collected for each vaccination regimen. Secondary aim of this study will be to assess the immune responses generated by vaccination.

What is being measured

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

  1. Safety assessment of new candidate malaria vaccines ChAd63 CS

    To assess the safety of new candidate malaria vaccines ChAd63 CS administered alone and with MVA CS in a prime-boost regime to healthy volunteers 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 (1)
  1. Assessment of immune response induced by vaccination

    To assess the humoral and cellular immune responses generated by ChAd63 CS when administered to healthy volunteers alone and with MVA CS 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

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ChAd63 CS, ChAd63 CS, MVA CS and ChAd63, MVA CS in people with Malaria, run by University of Oxford at 1 site in Ireland.

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 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 29 Nov 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 Ireland. 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 assessment of new candidate malaria vaccines ChAd63 CS (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 NCT01450280, 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 29 Nov 2012.
