ROCKVILLE, MD and SEATTLE, WA, USA – October 19, 2021 - Sanaria Inc. and Seattle Children’s Research Institute are proud to announce the signing of an agreement to collaborate on the development and commercialization of next generation PfSPZ vaccines attenuated by genetic engineering. Sanaria Inc. is the producer of the world’s first and only live radiation and chemically attenuated Plasmodium falciparum (Pf) whole malaria parasite sporozoite (SPZ) vaccines. Sanaria® PfSPZ Vaccine and Sanaria® PfSPZ-CVac vaccine have shown 100% protective efficacy against controlled human malaria infection with highly variant Pf parasites and importantly, protection against Pf infection in multiple trials in Africa. Dr. Stefan Kappe’s and Dr. Ashley Vaughan’s laboratories at Seattle Children’s Research Institute are world leaders in genetically engineering Pf parasites to create attenuated strains for vaccination.

The first joint project will develop a genetically attenuated, late liver stage-arresting replication competent (LARC) Pf parasite created in Dr. Stefan Kappe’s laboratory at Seattle Children’s (US Patent 10,905,753). These parasites are engineered to infect the liver and replicate, but do not leave the liver, allowing the immune system to safely generate potent protective immune responses. The PfSPZ-LARC vaccines will complement and improve on Sanaria’s first generation, radiation attenuated PfSPZ Vaccine, and replace the more potent PfSPZ-CVac vaccine. As compared to PfSPZ Vaccine, the PfSPZ-LARC vaccines are expected to provide better protection against malaria at a much lower dose, and thus will dramatically lower costs per dose, and like PfSPZ CVac, arrest late in liver stage and thus provides a broader spectrum immune response. The teams’ goal is the fielding of a malaria vaccine that prevents Pf infection in greater than 90% to 95% of recipients, and it is anticipated that a PfSPZ-LARC vaccine will meet this objective. The agreement also anticipates the development of additional genetically engineered PfSPZ vaccines to further improve protection.

“There are hundreds of millions of cases and at least half a million deaths from malaria every year,” said Dr. Stephen Hoffman, Sanaria’s Chief Executive and Scientific Officer. “We are incredibly excited about our collaboration with Seattle Children’s and the potential for the products that will arise from this collaboration. PfSPZ-LARC vaccines will form the foundation of next generation, highly protective vaccines to eliminate malaria. We have worked successfully with Dr. Kappe and Dr. Vaughan and their teams for many years, and this agreement solidifies our collaboration for years to come.”

Dr. Stefan Kappe, lead investigator for Seattle Children’s team, said, “We are thrilled to have a partner like Sanaria, which can develop, manufacture, clinically assess, and commercialize the genetically engineered parasites that arose from our research.”
