About Affinivax, Inc.

Affinivax is a clinical stage biopharmaceutical company pioneering the development of a novel class of vaccines designed to induce a broad and robust protective immune response to both disease-relevant polysaccharides and disease-relevant proteins in a single vaccine. Affinivax designs each of its vaccine candidates to optimize the protective immune response to one or both of these antigens utilizing the distinctive plug-and-play nature of its proprietary MAPS (Multiple Antigen Presenting System) platform technology, presenting the potential opportunity to make a significant step forward in addressing major healthcare challenges posed by novel and resistant infectious diseases. Affinivax’s lead vaccine candidate, ASP3772, is a Streptococcus pneumoniae vaccine that is being co-developed in collaboration with Astellas Pharma Inc. ASP3772 includes 24 pneumococcal polysaccharides, more than any other vaccine on the market or in clinical trials today, as well as two conserved pneumococcal proteins. ASP3772 was observed to be safe and highly immunogenic in a Phase 1 study in adults aged 18 to 64. A Phase 2 study in adults aged 65 to 85 is now completed with data analyses ongoing. The clinical program targeting the infant pneumococcal indication has been initiated with an ongoing Phase 1 study in healthy toddlers 12 to 15 months of age. Affinivax is also developing a next generation pneumococcal MAPS vaccine candidate to provide even broader protection than ASP3772, with an aim to establish and maintain a new standard-of-care vaccine for the protection against Streptococcus pneumoniae infections in both adults and infants. In addition, Affinivax is developing vaccine candidates against bacterial pathogens where previous vaccine approaches have not been successful, with active programs targeting healthcare-associated infections that primarily impact adults in medical and nursing home facilities, including Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, and Clostridium difficile, as well as exploratory programs targeting the SARS-CoV-2 virus and melanoma. Affinivax was founded in 2014 with a seed investment from the Bill & Melinda Gates Foundation and an exclusive license to the MAPS technology from Boston Children’s Hospital.
