Brii Biosciences Advances its Battle Against Hepatitis B, with Solutions Ranging from Prevention to Cure!

Brii Biosciences (2137.HK) has significantly expanded its commitment to combatting Hepatitis B Virus (HBV) infection through new license agreements with VBI Vaccines, Inc. (NASDAQ: VBIV). These agreements grant Brii Bio exclusive access to develop and commercialize the clinically differentiated 3-antigen adult HBV prophylactic vaccine, PreHevbri®, in Greater China and Asia Pacific countries.

Additionally, the exclusive worldwide license for BRII-179 (VBI-2601), has been extended, paving the way for significant progress towards an HBV functional cure. In exchange for these rights, VBI will receive upfront payments of $15 million, including a $3 million equity investment from Brii Bio, as well as a share of commercial and regulatory milestones, and royalties. This is an exciting development in driving greater access to antiviral treatments and HBV control in the region.

We are excited to grow our partnership with VBI and expand our HBV pipeline, demonstrating our dedication to public health and the fight against HBV. Our BRII-179 (VBI-2601) is undergoing Phase 2 trials in China, which has produced promising results in the effort to achieve a functional cure. Intending to improve upon cure rates enabled with PEG-IFN-α alone, the BRII-179 combined with BRII-835 (VIR-2218) can expand the populations eligible for the treatment.

Additionally, PreHevbri®, a 3-antigen HBV vaccine, which has shown 5 to 8x higher antibody titers than Engerix-B and no unexpected reactogenicity in its pivotal Phase 3 PROTECT and CONSTANT clinical studies, is approved for use in Asia and Europe. We look forward to unlocking substantial revenue potential in high HBV prevalence areas and offering a more durable curative approach as we improve and combine cure strategies.

About BRII-179 (VBI-2601)

BRII-179 (VBI-2601) is an exciting new immunotherapeutic candidate that may help achieve a functional cure for chronic HBV infection. This recombinant protein-based immunotherapy expresses Pre-S1, Pre-S2, and S HBV surface antigens, and is designed to boost B-cell and T-cell immunity. Currently, BRII-179 (VBI-2601) is being tested in two Phase 2 clinical trials in combination with BRII-835 (VIR-2218) and PEG-IFN-α, with promising results. We look forward to seeing the results of these studies and what this powerful immunotherapy can unlock for the future of HBV treatment.
