Aulis Capital Portfolio Company | EpiBiologics Named Among the World’s Most Promising Early-Stage Biotechs in Fierce Biotech’s 2026 Fierce 15
On 5 October, Fierce Biotech unveiled its 2026 Fierce 15, and Aulis Capital portfolio company EpiBiologics was among the honourees. Now in its 24th year, the annual list recognises 15 of the most promising private biotechnology companies, selected from more than 150 nominees worldwide.
About EpiBiologics
EpiBiologics was founded in 2021 and is headquartered in San Mateo, California. The company’s EpiTAC platform uses bispecific antibodies, with one arm binding a disease-causing target protein and the other binding a degradation receptor, to achieve targeted degradation of membrane and extracellular proteins. The company has also built an atlas of more than 270 degradation receptors.
Its lead candidate, EPI-326, is a tissue-selective, EGFR-degrading bispecific antibody that can degrade all oncogenic mutant forms of EGFR as well as wild-type EGFR. In April 2026, EPI-326 entered a global Phase 1 clinical trial in EGFR-driven non-small cell lung cancer and head and neck squamous cell carcinoma. The trial is currently in dose escalation, and clinical data could read out by mid-2027. The preclinical pipeline includes degrader–antibody-drug conjugates, a c-KIT programme and autoimmune programmes, among others.
In January 2026, the company completed a US$107 million Series B financing co-led by GV and Johnson & Johnson Innovation, with participation from Aulis Capital, Roche Venture Fund, Novartis Venture Fund and others.
The Aulis View
Unlike traditional protein degradation technologies, which focus on intracellular targets, EpiBiologics focuses on the emerging field of extracellular protein degradation. EPI-326 works regardless of mutation type and is tissue-selective, so it has the potential to address the resistance mutations and normal-tissue toxicity that limit existing EGFR therapies.
“Being recognised as a Fierce 15 company is a testament to the team’s relentless dedication to novel science and patient impact. At Aulis Capital, we couldn’t be prouder to partner with Ann Lee-Karlon and the visionary leadership team at EpiBiologics as they usher in the next wave of bispecific degrader therapeutics.”
— Nisa Leung, Founding Managing Partner, Aulis Capital
