What EpiVax does
EpiVax is a Providence, Rhode Island-based contract research organization (CRO) founded in 1998 that specializes in computational immunogenicity risk assessment for biologic therapeutics, vaccines, and generic peptide drugs. The company combines proprietary in silico T cell epitope prediction algorithms (EpiMatrix®, JanusMatrix™, ClustiMer™, OptiMatrix™) with human-relevant in vitro assay services (Whole Blood, PBMC, DC:PBMC, Class II HLA Binding) to provide integrated immunogenicity screening, protein reengineering, and regulatory submission support. Its flagship ISPRI™ platform and iVAX™ vaccine design toolkit serve pharmaceutical, biotech, vaccine developer, and generic peptide clients, with the PANDA® service specifically supporting FDA ANDA pathway approvals (16+ supported to date) and the Ancer® platform addressing personalized neoantigen-based cancer vaccine development.
EpiVax generates revenue through five primary streams: tiered fee-for-service computational analyses (ISPRI Downselect™, Quantify™, Evaluate™, HCP™), in vitro laboratory assays, Trusted Expert Advice (TEA) consulting and IRA/ISI regulatory writing services, software licensing of ISPRI™ and iVAX™ platforms (annual subscriptions), and technology licensing of Tregitopes™ and Ancer® for partner development. The company employs 11-50 staff operating from a single Providence headquarters, with sales executed through a dedicated business development team employing consultative, relationship-driven engagement with scientific experts. Marketing relies on scientific thought leadership: 240+ peer-reviewed publications, annual industry seminars (Amsterdam, Japan Westin for 17 years, AI/HI Workshop), and direct enterprise outreach to pharmaceutical R&D leaders.
In April 2026, EpiVax was acquired by SV Health Investors, a healthcare-focused private equity firm, with founders Annie De Groot and Bill Martin transitioning to consulting roles. Under new ownership, the company has expanded its laboratory footprint, launched AI-driven ADA prediction capabilities (74% accuracy within 10% of clinical rates), and broadened its platform into emerging modalities including gene therapy and CAR-T. The firm maintains ongoing FDA co-development relationships through grants and contracts, and counts 18 of the top 20 global pharmaceutical companies among its historical client base.
