Aegis Life Receives Investment to Continue Development of DNA-Encoded Therapeutic Antibodies Against Infectious Diseases Using the Fusogenix PLV Platform

SAN DIEGO & EDMONTON, Alberta--(BUSINESS WIRE)-- Aegis Life, Inc. (Aegis) and its parent company Entos Pharmaceuticals (Entos) announced today that Aegis Life has received a program-related investment from the Bill & Melinda Gates Foundation (the “foundation”).

Aegis will receive up to $4.45 million in funding through a convertible promissory note from the foundation’s Strategic Investment Fund for the purpose of developing DNA-based encoded neutralizing antibody therapies for infectious diseases using the Entos Fusogenix PLV platform. This investment follows an initial grant from the foundation to Aegis made in June 2023 to support this collaborative development project with a focus on HIV and malaria. Aegis and Entos will also commit to making any resulting neutralizing antibody therapeutics for these conditions available and accessible to those most in need, including low- and middle-income countries.

“We are thrilled that the Bill & Melinda Gates Foundation, based on promising data from our previous grant-funded work, continues to support this exciting project to develop DNA-encoded antibody therapeutics,” said John Lewis, Ph.D., CEO of Aegis.

HIV and malaria persist globally and result in significant mortality worldwide. “Neutralizing antibodies are promising treatments in the fight against HIV and other serious infectious diseases and work by blocking transmission and reducing disease severity,” said Dr. Steve Chen, Chief Medical Officer at Aegis Life. “The high stability, durability, and potency profile of the PLV technology makes PLV-based DNA-encoded antibodies perfectly suited for deployment in the countries bearing the brunt of these infections. We’re grateful for this latest support, which provides Aegis the opportunity to perform necessary research that could save the lives of those who are most vulnerable.”

Treating viral diseases with neutralizing antibodies is an important defense because these antibodies can block infection when they bind to the virus. This approach has been highly effective when used therapeutically by infusing patients with purified neutralizing antibodies, but it is limited by low durability and high cost. To address this, Aegis and Entos are developing DNA-encoded antibodies using the Fusogenix PLV platform that can be administered through intramuscular injection. This approach enables the patient’s own cells to manufacture and secrete neutralizing antibodies, allowing for high durability at a substantially lower cost. The Fusogenix PLV is fridge-stable and can be manufactured at scale cost-effectively, making it accessible for those living in rural, remote, or infrastructure-poor regions.
