There are about 140 clinical studies being (or have been) conducted in Mozambique. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to compare the efficacy of sulfadoxine-pyrimethamine plus artesunate with that of sulfadoxine-pyrimethamine on its own for the treatment of uncomplicated malaria.
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).
Malaria is an important cause of death and serious illness among Mozambican children. Although the risk of malaria can be reduced by drugs and by impregnated bed nets, it would be helpful if children could be protected against malaria by a vaccine. GSK Biologicals is developing in partnership with 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. Previous studies have shown the candidate malaria vaccine RTS,S/AS02 to be safe when administered in adults and children aged 1-11 years. However, to assess if this vaccine could provide protection against malaria in children, this study has been undertaken.
GSK Biologicals is developing in partnership with the Program for Appropriate Technology in Health (PATH) Malaria Vaccine Initiative a candidate malaria vaccine 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. The vaccine would also provide protection against infection with hepatitis B virus (HBV). This trial is being carried out following the demonstration of efficacy of a previous version of the malaria candidate vaccine in children in Mozambique: there, the vaccine demonstrated approximately 30% efficacy against clinical episodes of malaria and approximately 58% efficacy against severe malaria disease. In order to integrate the malaria vaccine into the Expanded Program on Immunization (EPI) regimen, in malaria-endemic regions, for this trial, a 0.5 ml dose of GSK 257049 vaccine has been developed. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
