Graphic element The Second Phase of a European Malaria Vaccine Development Consortium


The EUROMALVAC2 consortium will develop malaria vaccines inducing protective antibody responses to Plasmodium falciparum bloodstage antigens, moving leading vaccine candidates towards GMP-production and clinical trial whilst validating second and third generation candidates in its malaria vaccine R&D 'pipeline '. The major projects within the EUROMALVAC2 work programme involve: a) an optimisation of synthesis of lead candidate malaria vaccines based on merozoite surface protein 1 (MSPl ) and the apical merozoite antigen 1 (AMAl ); b) production and testing of more parasitised erythrocyte membrane protein (PfEMP-l)-based vaccines; c) production and testing of new vaccine formulations based on the N-terminal Block 2 sequences of MSP1 and on other, less well characterised merozoite antigens; d) development of a transmission blocking vaccine based on gametocyte antigen Pfs48/45; e) strengthening of preclinical and clinical testing facilities.


EUROMALVAC1 has brought PfMSP119 and PfAMA1 vaccines close to clinical trial and has developed an experimental PfEMP1 vaccine. More second generation vaccines are now needed for clinical trials and accelerated development of an effective malaria vaccine. EUROMALVAC2's plan is to expand Europe's portfolio of vaccines inducing protective antibody responses to key malaria antigens, continuing to validate vaccine constructs in the pipeline while optimising the lead vaccines in preparation for their phase I trials. More 'first' generation PfEMP1 vaccines will be tested, as will a novel MSP1 Block 2 vaccine. Development and validation studies will be initiated for MSP 3-8 and a prototype transmission blocking vaccine will be made. Further development of pre-clinical and clinical trial facilities will be carried out.


1) Immunogenicity of MSP119 and AMA1 will be improved using adjuvants and modified antigen to increase inhibitory antibodies. a) Combined vaccines, initially fusing MSP1 with AMA1 will be tested. b) Structural analysis of merozoite surface molecules will be further developed. c) Other merozoite surface proteins will be added to the vaccine development pipeline. d) MSP1 N-terminal Block 2 vaccine development will be accelerated, testing hepatitis B core antigen vaccines and protein, DNA, and virus-like particle vaccines. e) Precise identification of protective epitopes on PFEMP1 molecules and their production as recombinant molecules will be carried out. f) Coordinated efforts to purify recombinant PfEMP1 in native antigenic conformation will be made. g) PfEMP1 vaccines inducing antibody-blocking cytoadhesion will be tested on Saimiri monkeys. h) Transmission-blocking vaccine development will be accelerated using the Pfs48/ 45 antigen. i) Stable vaccinia viruses expressing Pfs48/45 markers.
2) Develop auxotrophic Plasmodium parasites dependent upon an exogenous supply of uracil by targeted deletion of the cloned parasite ura 3 gene.
3) Rationally develop axenic culture of malaria parasites, based upon detailed measurements of the intracellular environment of the infected erythrocyte.
4) Develop genetically engineered Plasmodium that is growth impaired through a strategic reduction in its ability to produce protein.
5) Initiate a discussion about genetically engineered malaria parasites in Africa that will further debate the application of attenuated parasites and liase with similar fora in Europe.

Milestones and expected results:

The second phase of the EUROMALVAC consortium's activity will accelerate the progress of the first generation lead candidate vaccines to clinical trial within the next 36 months. The urgent need to expand development of the pipeline of second generation candidate vaccines will be addressed in order to develop an effective malaria vaccine capable of inducing protective antibody responses to blood-stage parasite antigens.
