| Jan 2026 | Series B | GV (lead); Johnson & Johnson Innovation (lead); Digitalis Ventures; Novartis Venture Fund; Taiho Ventures; Polaris Partners; Vivo Capital; Avego Bioscience Capital; Samsara BioCapital; Aulis Capital; Mission BioCapital; Codon Capital | $107M | EpiBiologics, a San Mateo, California biotechnology company, closed a $107 million Series B financing on January 8, 2026. GV and Johnson & Johnson Innovation - JJDC co-led the round, with new investors Novartis Venture Fund, Aulis Capital, Avego BioScience Capital and Samsara BioCapital joining existing investors Polaris Partners, Digitalis Ventures, Taiho Ventures, Vivo Capital, Codon Capital and Mission BioCapital. The proceeds will take the lead program EPI-326 into first-in-human trials, support additional oncology and immunology programs and combinations with antibody-drug conjugates, and fund new hires including a chief medical officer and chief financial officer, with multiple years of runway. EpiBiologics develops tissue-selective extracellular protein degraders on its EpiTAC platform, building bispecific antibodies that degrade disease-driving membrane and soluble proteins in oncology and immunology. The company was launched in 2023 from research by University of California San Francisco professor Jim Wells with a $50 million Series A. EPI-326 is a bispecific antibody against cancerous forms of EGFR for lung and head and neck cancer, designed to localize degradation to tumors while sparing healthy tissue and so offer a better safety profile than existing EGFR therapies. EpiBiologics plans to name its second program later in 2026. |

EpiBiologics was founded in 2022 on work by Jim Wells at UCSF and develops the EpiTAC platform, a modular antibody-based system for tissue-specific degradation of disease-driving membrane and extracellular proteins. Its programs target cancer, immunology and neurological diseases, and the funds support the platform and early pipeline programs. |

EpiBiologics is a California biotechnology company developing an antibody-based protein degradation platform, EpiTAC, aimed at membrane and extracellular drug targets in areas such as oncology and immunology. The platform uses bispecific antibodies to direct disease-driving proteins to degradation, and the company said the financing would advance its platform and build its pipeline of bispecific antibody protein degraders toward the clinic. The company was founded in 2022 and stems from academic work by Dr. James Wells of the University of California, San Francisco. Financial terms beyond the amount raised, including valuation, were not disclosed. |
