ClearB Therapeutics Announces Upcoming Poster Presentation of Pre-Clinical Chronic Hepatitis B Data at EASL 2025

CONCORD, Mass.--(BUSINESS WIRE)--ClearB Therapeutics, Inc., a company developing therapeutic vaccines designed to drive a functional cure for Hepatitis B, announced today that an abstract will be presented as a poster at the European Association for the Study of the Liver (EASL) International Liver Congress (ILC) 2025, taking place in Amsterdam, the Netherlands 7 – 10 May 2025.

“We are excited to share preclinical data on our therapeutic vaccine candidate, CLB-4000, with the Hepatitis B community,” said Aileen Rubio, PhD, CEO of ClearB Therapeutics. “Chronic Hepatitis B (CHB) infection remains a substantial global health care problem in need of effective antiviral and immunomodulatory therapies. We continue to believe that the functional cure insights translated into the HBsAg variants, CLB-405 and CLB-505, will greatly benefit from the unique adjuvant properties of TQL-1055 and could become an important component of treatment regimens.”

About TQL-1055

TQL-1055 is a rationally designed, semi-synthetic analogue of the QS-21 saponin adjuvant, which is used in the currently available shingles vaccine. Saponin adjuvants are potent immune stimulators and important components of licensed, currently marketed, and clinically-advanced infectious disease vaccines. The usefulness of saponin adjuvants has been constrained by dose-limiting tolerability and manufacturing challenges. TQL-1055 is designed to have improved tolerability and to provide the same strong immune response as QS-21 and has shown favorable tolerability in a Phase 1 clinical trial.
