Core Viewpoint - The company has announced promising results from the ENSURE II Phase study, indicating the potential of BRII-179 in achieving functional cure for hepatitis B virus (HBV) infection, with sustained benefits observed in HBsAg clearance among responders [1][2]. Group 1: Study Results - In the BRII-179 responder group, 58% (11 out of 19) achieved HBsAg clearance at the end of treatment (EOT), compared to only 17% (2 out of 12) in the non-responder group [2]. - After 24 weeks post-treatment, 42% (8 out of 19) of the responders maintained HBsAg clearance, while only 8% (1 out of 12) of non-responders did [2]. - Previous studies indicated that 50% (4 out of 8) of responders maintained HBsAg clearance 24 weeks after EOT, even with baseline HBsAg levels between 1,514-3,086 IU/mL, showcasing BRII-179's potential across different patient populations [2]. Group 2: Ongoing Research - The company is conducting two additional Phase IIb studies: ENRICH, which evaluates BRII-179's role in inducing HBV-specific immune responses, and ENHANCE, which assesses the effects of a combination therapy involving BRII-179, elebsiran, and PEG-IFNα [3]. - ENHANCE consists of two parts: one assessing the simultaneous administration of the three drugs for 48 weeks, and the other exploring a sequential approach with 24 weeks of BRII-179 and elebsiran followed by 24 weeks of combination therapy [3]. - Both studies have completed patient recruitment and are expected to report EOT data in 2026 [3].
