About this study

Official title: Double-blind,Randomized,Controlled,Dose Escalation Phase 1 Trial in 12-47 Month Old Children in Western Kenya to Evaluate the Safety and Immunogenicity of WRAIR's MSP-1(FMP1) Malaria Vaccine Adjuvanted in GSK's AS02A Versus Rabies Vaccine.

To assess the safety and reactogenicity of the FMP-1/AS02A malaria vaccine in malaria-exposed children living in western Kenya and aged 12-47 months

Read the detailed description

Study consists of 3 cohorts (12 to 23 months, 24 to 35 months, and 36 to 47 months). Within each cohort subjects were randomized in a 2:1 ration to receive one of three dose levels of FMP1/AS02A (Cohort A, 10 ug; Cohort B, 25 ug; Cohort C, 50 ug) or Imovax Rabies vaccine. Immunization was staggered among dose cohorts; subjects in Cohort B received their first immunization only after the Local Medical Monitor and Data Safety Monitoring Board reviewed Cohort A safety data for the eight-day follow-up period following their first immunization. The same procedure was followed for the immunization of Cohort C. This will be conducted in western Kenya a the Walter Reed Project Lumbewa Clinic.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing FMP1/AS02A Malaria vaccine and Imovax Rabies vaccine in people with Plasmodium Falciparum Malaria, run by U.S. Army Medical Research and Development Command 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 3 inclusion and 23 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 2 Oct 2017. 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?

Yes. Results are posted in the registry (first posted 2 Oct 2017). 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?

Occurrence of Solicited Symptoms During a 8 Day Follow-up Period After Each Vaccination (time frame: 40 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 NCT00317473, which also lists 4 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 2 Oct 2017.
