Brii Biosciences Data Backs Shorter NRTI Use in Next-Generation HBV Therapies

Story Highlights
  • Brii Biosciences reported cross-study Phase 2 data showing limited and clinically manageable HBsAg rebound after treatment with pegylated interferon alfa alone or combined with BRII-179 or elebsiran in NRTI-experienced HBV patients.
  • The analysis suggests durable immunological control and indicates NRTIs may be safely discontinued sooner, potentially shortening or eliminating consolidation periods and strengthening the case for BRII-179 and elebsiran in future HBV cure regimens.

An announcement from Brii Biosciences Limited ( (HK:2137) ) is now available.

Brii Biosciences has presented new data at the Asian Pacific Association for the Study of the Liver meeting in Istanbul, detailing a cross-study analysis of post-treatment hepatitis B surface antigen rebound in NRTI-experienced patients from its Phase 2 ENSURE and BRII-179-002 trials. The pooled analysis assessed the incidence, magnitude and clinical significance of HBsAg rebound after end of treatment in patients receiving pegylated interferon alfa alone or in combination with elebsiran or BRII-179.

The findings indicate that off-treatment clinical outcomes were favorable, with all HBsAg rebounds remaining below 100 IU/mL and most below 10 IU/mL, while HBV DNA rebound was rare and not associated with significant ALT elevations. These results suggest durable post-treatment immunological control, support the potential for safely discontinuing NRTIs in pegylated interferon-based combination regimens, and imply that shorter or even eliminated NRTI consolidation periods could be feasible in future HBV cure strategies, reinforcing the strategic value of BRII-179 and elebsiran in the company’s pipeline.

The most recent analyst rating on (HK:2137) stock is a Hold with a HK$2.00 price target. To see the full list of analyst forecasts on Brii Biosciences Limited stock, see the HK:2137 Stock Forecast page.
