H1 2025 earnings summary21 Aug, 2025

Executive summary

  • Advanced three fully enrolled Phase 2b HBV clinical studies (ENSURE, ENRICH, ENHANCE), targeting a functional cure for chronic HBV and defining optimal combination regimens.

  • BREE-179 and BRII-179 showed promising data in enhancing anti-HBs response and accelerating HBsAg loss, supporting shorter PEG-IFNa treatment.

  • Out-licensed non-core programs, including soralimixin (BRII-693) and Xarelin mixing, in Greater China to focus on HBV and leverage partnerships.

  • Entered new licensing agreement for psoriatic mixing targeting antimicrobial resistance in Greater China.

  • Maintained strong cash position, supporting late-stage development and R&D through 2028.

Financial highlights

  • Cash and cash equivalents as of 06/30/2025 were RMB2,075.3 million, down 14% from RMB2,413.4 million at end of 2024.

  • Loss for the period narrowed 47.5% year-over-year to RMB148.8 million, mainly due to lower operating expenses and fair value changes in equity investments.

  • Other income for H1 2025 was RMB28.1 million, a 60.4% decrease year-over-year, mainly due to lower banking interest income and reduced government grants.

  • R&D expenses for H1 2025 declined 7.3% to RMB117 million, reflecting pipeline prioritization and lower third-party and employee costs.

  • Administrative expenses dropped 26% to RMB58.2 million, driven by reduced employee, facility, and professional service costs.

Outlook and guidance

  • Sufficient funds to support operations through 2028.

  • 24-week follow-up data from ENSURE/INSURE cohort 4 expected in H2 2025; end-of-treatment data from ENRICH and ENHANCE studies anticipated in H1 2026.

  • Unutilized IPO proceeds expected to be used by end of 2027, mainly for HBV, HIV, and MDR/XDR programs.

  • Ongoing regulatory discussions for Phase 3 study design and endpoints, with focus on biomarker-driven patient enrichment strategies.

  • Focus remains on advancing HBV cure candidates to registrational studies and seeking partnerships for non-HBV assets.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
