Summary

This is an open-label, multi-centre Phase I/IIa dose escalation blood-stage malaria CHMI trial to assess the safety, immunogenicity and efficacy of the candidate malaria vaccine RH5.1/AS01. All volunteers recruited will be healthy, malaria naïve adults aged between 18 and 45 years.

Volunteers will be recruited and vaccinated at the CCVTM, Oxford; Guys and St Thomas' NIHR CRF, London; and the NIHR WTCRF, Southampton for the Phase Ia part of the trial, and at the CCVTM, Oxford and Guys and St Thomas' NIHR CRF, London for the Phase IIa stage.

BIOLOGICAL

RH5.1/ ASO1

The RH5.1 protein consists of the entire full-length ectodomain of the PfRH5 antigen (amino acids E26 - Q526) with the sequence based on the 3D7 clone of P. falciparum. The AS01 adjuvant system has been developed and manufactured by GlaxoSmithKline (GSK) Biologicals and is presented as a liquid solution in a monodose glass vial. AS01 is a liposome-based Adjuvant System with a specific aim to improve cell-mediated immunity.
