Overview of Brii Biosciences Limited
Brii Biosciences Limited is a biotechnology company committed to developing innovative therapeutic solutions that address critical public health challenges. With a core focus on chronic hepatitis B virus (HBV) infections and additional efforts in central nervous system and infectious diseases, the company is advancing a diversified pipeline that includes immunotherapeutics, siRNA-based treatments, and neutralizing monoclonal antibodies. With its operations spanning major biotech hubs such as Raleigh-Durham, the San Francisco Bay Area, Beijing, and Shanghai, Brii Biosciences leverages cutting-edge technologies and strategic collaborations to enhance patient care.
Core Therapeutic Modalities and Pipeline
The company has developed a robust portfolio of therapeutic candidates designed to achieve functional cures for chronic HBV infection. Among its lead programs are:
- BRII-877 (Tobevibart): An investigational monoclonal antibody engineered with extended half-life technology, designed to neutralize HBV and hepatitis D virus (HDV) by blocking viral entry into hepatocytes and reducing circulating virions.
- BRII-835 (Elebsiran): A novel siRNA therapeutic utilizing Enhanced Stabilization Chemistry Plus (ESC+) technology to directly target and degrade HBV RNA transcripts, thereby reducing the production of hepatitis B surface antigen (HBsAg).
- BRII-179: A recombinant protein-based immunotherapeutic that presents key HBV antigens to stimulate robust B-cell and T-cell responses. This candidate is designed to break immune tolerance and potentially enhance viral control when used in combination treatment regimens.

Brii Biosciences Limited reported its fiscal year 2022 results, highlighting a revenue increase to RMB51.6 million due to the COVID-19 therapy commercialization in China. The company is focused on advancing its clinical programs for hepatitis B and depression, with Phase 2 trials set for 2023. Financially, R&D expenses decreased by 10.9% to RMB440.6 million, while total comprehensive expense fell by 94.4% to RMB238.5 million. Brii Bio discontinued its COVID-19 antibody program to prioritize its main clinical projects and remains well-funded through 2025.
Brii Biosciences announced significant clinical development updates, focusing on two lead programs for hepatitis B and postpartum depression. The company completed patient enrollment in Phase 2 trials for both areas, revealing promising preliminary results. Notably, the U.S. FDA lifted the clinical hold on BRII-732, allowing a restart of trials for a potential HIV treatment. While the company aims to address high unmet medical needs, it also plans to explore partnerships for its discontinued HIV candidate, BRII-778.
Brii Biosciences announced promising results from two Phase 1 studies evaluating BRII-732 and BRII-778 for HIV treatment. Both candidates showed safety and tolerability, suggesting potential for a once-weekly oral combination therapy. Data presented at IDWeek 2022 highlighted their favorable pharmacokinetic profiles, which may enhance adherence compared to daily regimens. Brii aims to advance these compounds through clinical development, addressing the needs of over 38 million people living with HIV globally.
Brii Biosciences announced the top-line results from its Phase 1 study of BRII-296, a long-acting, single-injection therapy for postpartum depression (PPD). The 600 mg dosage was shown to be safe and well-tolerated, with a favorable pharmacokinetic profile. These findings position BRII-296 as a potential one-time outpatient treatment for PPD, addressing the needs of the 900,000 individuals affected in the U.S. annually. The company plans to move forward with a Phase 2 clinical trial by the end of 2022, focusing on patient-centered development.
