About this study
Official title: A Bridging Study to Evaluate the Safety and Immunogenicity of GSK Biologicals' Candidate Vaccines RTS,S/AS02D (0.5 mL Dose) and RTS,S/AS02A (0.25 mL Dose) Administered According to a 0, 1, 2 Month Vaccination Schedule in Children Aged 3 to 5 Years Living in a Malaria-endemic Region of Mozambique.
GSK Biologicals is developing in partnership with the Malaria Vaccine Initiative at PATH a candidate malaria vaccine RTS,S/AS02 for the routine immunization of infants and children living in malaria endemic areas. The vaccine would offer protection against malaria disease due to the parasite Plasmodium falciparum and also would provide protection against infection with hepatitis B virus. Studies conducted using the formulation RTS,S/AS02A (0.25 ml dose) in children and adults have shown to be safe. Currently all intramuscular vaccines in the EPI schedule are administered at a dose volume of 0.5 ml and in this context, a new variant of RTS,S/AS02D (0.5 ml dose) formulation has been composed which has the same active constituents in the same quantities as in a 0.25 ml dose of RTS,S/AS02A. In this study, RTS,S/AS02D (0.5 ml dose) was compared to the existing formulation, RTS,S/AS02A (0.25 ml dose).
Read the detailed description
Children participating in this study will either receive RTS,S/AS02D (0.5 ml dose) or RTS,S/AS02A (0.25 ml dose) intramuscularly according to 0, 1, 2 months schedule. The children will be followed-up throughout the study period to record safety events. Blood samples will be collected at defined time points to assess the subject's immune response to the relevant immunological indicators.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing RTS,S/AS02D and RTS,S/AS02A in people with Malaria, run by GlaxoSmithKline at 1 site in Mozambique.
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 1 inclusion and 1 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 27 Dec 2019. 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 Mozambique. 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?
Occurrence of solicited and unsolicited symptoms and serious adverse events during the entire study period; to assess antibody levels for relevant immunological indicators at time points when post completion of vaccination schedule.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 27 Dec 2019.
