Project description
Targeting malaria at multiple stages to cut transmission
The HORIZON 2024 EDCTP3 call highlights the need for a vaccine to interrupt malaria transmission. The first licensed malaria vaccines, RTS,S and R21, are expected to reduce childhood deaths in Africa. Building on this progress, the EU-funded PfVIMT project aims to accelerate approval of Pfs230D1+R21, the first multistage malaria vaccine designed to interrupt transmission, reduce clinical disease and eliminate malaria from communities. While R21 targets Plasmodium sporozoites in skin and liver, Pfs230D1 disrupts gametes in mosquitoes, achieving >85 % reduction in mosquito infection during a Phase 2 trial. Pfs230D1+R21 efficacy will be assessed by an in vivo direct skin feeding bioassay that mimics natural parasite transmission. Mathematical modelling suggests Pfs230D1+R21 could reduce malaria burden in high-transmission regions by up to 80 %.
Objective
This proposal responds to the HORIZON 2024 call “EDCTP3 Joint Undertaking: Research on existing Malaria vaccines and development of new promising candidates.”The malaria epidemic will not stop without a safe, efficacious, and affordable vaccine that can interrupt transmission. The first licensed malaria vaccines, RTS,S and R21, will substantially reduce childhood deaths in Africa. We propose to pursue accelerated approval of Pfs230D1+R21, the first multi-stage malaria vaccine to reduce transmission, which will reduce clinical malaria rates and support control and elimination. While R21 kills sporozoites in skin/liver, Pfs230D1 lyses gametes in mosquitoes. In field trials with adults and children, Pfs230D1 reduced mosquito infection rates >75%. Pfs230D1+R21 development relies on in-vivo direct-skin-feeding (DSF) bioassay, that feeds mosquitoes on skin to recapitulate natural parasite transmission, to measure reasonably likely surrogate efficacy endpoints for accelerated licensure. Modelling R21 and Pfs230D1 field efficacy data suggests Pfs230D1+R21 will substantially reduce malaria burden in high-transmission zones, while other simulations predict accelerated elimination in low-transmission zones. Through innovative trial designs and capacity-building, we will pursue EDCTP3 aims: 1) establish safety and efficacy of a multi-stage vaccine to reduce transmission; 2) pursue accelerated approval of Pfs230D1+R21; 3) expand population-wide long-term safety and efficacy data on R21; and 4) generate expertise and data to inform recommendations that expand cGMP and supply chain for vaccines in Africa. The program will expand clinical trial capacity for transmission-blocking interventions, build expertise and evidence to support future vaccine manufacture in Africa, and improve understanding of malaria immunity including correlates of protection. At project end, an approved multi-stage malaria vaccine to reduce transmission will be poised for Phase 4 cluster-randomized trials.
