A Phase 1/2b Study of an Investigational Malaria Vaccination Strategy in 5-17 Month Old Infants and Children in Burkina Faso

Malaria Clinical Trial

Official title:
A Phase 1/2b Double Blind Randomised Controlled Trial of the Efficacy, Safety and Immunogenicity of Heterologous Prime-boost Immunisation With the Candidate Malaria Vaccines ChAd63 ME-TRAP and MVA ME-TRAP in 5-17 Month Old Burkinabe Infants and Children

Clinical Trial Summary

Prime boost vaccination with ChAd63 ME-TRAP followed eight weeks later with MVA ME-TRAP shows efficacy against malaria infection when tested in UK volunteers using sporozoite challenge experiments. It is a leading candidate vaccination strategy against malaria. In the field, Phase I studies have been conducted in adults in Kenya and The Gambia and children and infants in The Gambia. The vaccination strategy appears safe and well tolerated in these populations, and also shows impressive immunogenicity, not significantly different to that seen in the UK trials where efficacy was shown. In particular, recent data from The Gambia shows excellent safety and immunogenicity in infants in malaria endemic areas, who would be the ones to benefit most from such a vaccine against malaria. With this clinical development as background, the investigators now propose to evaluate efficacy against natural malaria infection in this important target group for an effective malaria vaccine, that is, 5-17 month infants and children living in malaria endemic areas. The proposed study area, Banfora, Burkina Faso, is highly endemic for Plasmodium falciparum malaria.
