About Hepatitis B

Hepatitis B is one of the world’s most significant infectious disease threats with more than 290 million people infected globally. HBV infection is the leading cause of liver disease and, with current treatments, it is very difficult to cure, with many patients going on to develop liver cancers. An estimated 780,000 people die each year from complications of chronic HBV such as liver decompensation and hepatocellular carcinoma.

About BRII-179 (VBI-2601)

BRII-179 (VBI-2601) is a novel recombinant, protein-based HBV immunotherapeutic candidate that builds upon the 3-antigen conformation of VBI’s prophylactic 3-antigen HBV vaccine candidate, and is designed to target enhanced B-cell and T-cell immunity. Brii Biosciences licensed BRII-179 (VBI-2601) from VBI Vaccines in December of 2018, providing Brii with commercial rights to BRII-179 (VBI-2601) in the licensed territories of China, Hong Kong, Macau, and Taiwan.
