| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| 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 is a biotechnology company based in San Mateo, California, specializing in tissue-selective extracellular protein degradation using its EpiTAC platform to develop novel bispecific antibodies that selectively degrade disease-driving membrane and soluble protein targets in oncology and immunology. The company was launched in 2021 or 2023 from research by University of California San Francisco professor Jim Wells and previously raised a $50 million Series A round. Its lead program, EPI-326, is a bispecific antibody targeting cancerous forms of EGFR for lung cancer and head and neck cancer, designed to localize degradation to tumors while sparing healthy tissue, with plans to enter first-in-human clinical trials in early 2026. On January 8 or 12, 2026, EpiBiologics closed a $107 million Series B financing round co-led by GV (Google Ventures) and Johnson & Johnson Innovation – JJDC, Inc., matching the specified investors including new participants Novartis Venture Fund, Aulis Capital, Avego BioScience Capital, and Samsara BioCapital, alongside existing investors Polaris Partners, Digitalis Ventures, Taiho Ventures, Vivo Capital, Codon Capital, and Mission BioCapital. The proceeds will advance the pipeline, including EPI-326 into clinical trials, support additional programs in oncology and immunology, combinations with antibody-drug conjugates, and company expansion including new hires for chief medical officer and chief financial officer roles, providing multiple years of runway. The company positions its degraders as differentiated from existing EGFR therapies by offering improved safety profiles through tissue selectivity. EpiBiologics plans to name its second program later in 2026 and emphasizes orthogonal approaches and combinations to address evolving cancer treatments. |
| Jul 2023 | Series A | Digitalis Ventures; Taiho Ventures; GV; Polaris Partners; Vivo Capital; Mubadala; Codon Capital | $23M | EpiBiologics, a biotechnology company founded in 2022 based on pioneering work from Dr. Jim Wells at UCSF, develops the EpiTAC platform—a modular antibody-based system for tissue-specific degradation of disease-driving membrane and extracellular proteins, targeting applications in cancer, immunology, and neurological diseases. The company launched in March 2023 with a $50 million Series A financing led by Mubadala Capital, Polaris Partners, Vivo Capital, and GV. On July 20, 2023, EpiBiologics extended its Series A by raising an additional $23 million from new investors Digitalis Ventures, Taiho Ventures, and existing investor Codon Capital, bringing the total Series A to $73 million. Ann Lee-Karlon, Ph.D., was appointed CEO and President alongside the financing extension, tasked with expanding the EpiTAC platform, forging collaborations, and advancing the pipeline of bispecific antibody protein degraders. The funds support progression of the platform and early pipeline programs. EpiBiologics later raised a $107 million Series B in 2025 co-led by GV and Johnson & Johnson Innovation–JJDC to advance its pipeline, including lead program EPI-326—a bispecific antibody for degrading cancerous EGFR in lung and head & neck cancers—into first-in-human trials in early 2026. The Series B included participation from prior investors like Polaris Partners and new ones such as Novartis Venture Fund and Samsara BioCapital, highlighting the platform's potential in oncology and immunology. |
| Mar 2023 | Series A | Mubadala (lead); Polaris Partners (lead); GV; Vivo Capital | $73M | EpiBiologics is a San Mateo, California-based biotechnology company founded in 2021-2022, developing tissue-selective extracellular protein degradation therapies via its proprietary EpiTAC platform, a modular bispecific antibody system targeting disease-driving membrane and soluble proteins in oncology and immunology. The platform enables precise degradation in a tissue-specific manner, with lead program EPI-326 advancing toward a first-in-human clinical trial in early 2026 for non-small cell lung cancer and head and neck squamous cell carcinoma. The company also pursues bispecific antibodies, antibody-drug conjugates, and combination approaches for cancer and immune diseases. Later $107M Series B in 2025 (date not specified) was co-led by GV and Johnson & Johnson Innovation–JJDC, with participation from Novartis Venture Fund, Aulis Capital, Avego BioScience Capital, Samsara BioCapital, and existing investors including Polaris Partners, Digitalis Ventures, Taiho Ventures, Vivo Capital, Codon Capital, and Mission BioCapital. Traction includes pipeline advancement, with EPI-326 noted for potential safety advantages by selectively degrading tumor-specific EGFR while sparing healthy tissue.
