Welcome to our dedicated page for Arbutus Biopharma Corporation news (Ticker: ABUS), a resource for investors and traders seeking the latest updates and insights on Arbutus Biopharma Corporation stock.
Arbutus Biopharma Corporation (Nasdaq: ABUS) is a clinical-stage biopharmaceutical company dedicated to discovering, developing, and commercializing a cure for patients suffering from chronic hepatitis B infection (cHBV). Utilizing its extensive expertise in virology, Arbutus focuses on developing a portfolio of drug candidates with multiple mechanisms of action aimed at curing Hepatitis B virus (HBV) disease. The company's lead RNA interference (RNAi) therapeutic, imdusiran (AB-729), targets HBV proteins to reduce viral antigens and reawaken the host's immune response. Imdusiran is currently undergoing multiple Phase 2a clinical trials, demonstrating promising results in reducing hepatitis B surface antigen (HBsAg) levels and achieving functional cures in a subset of patients.
Arbutus leverages its proprietary lipid nanoparticle (LNP) technology and expertise in RNAi therapeutics to develop innovative treatments. Beyond HBV, the company has a robust pipeline that includes AB-101, an oral PD-L1 inhibitor, currently in Phase 1a/1b trials. This compound aims to enable controlled checkpoint blockade while minimizing systemic safety issues.
Recent clinical data highlight the potential of Arbutus' combination therapies. In the IM-PROVE I trial, imdusiran combined with pegylated interferon alfa-2a (IFN) and nucleos(t)ide analogue (NA) therapy demonstrated sustained HBsAg loss in some patients, suggesting a path toward a functional cure. Another study, IM-PROVE II, showed that combining imdusiran with VTP-300, an immunotherapeutic, resulted in meaningful reductions in HBsAg levels and the discontinuation of NA therapy in a significant number of patients.
Financially, Arbutus maintains a strong position with a cash runway extending into the first quarter of 2026. They are actively involved in ongoing patent litigation to protect their LNP technology, seeking fair compensation for its use in mRNA COVID-19 vaccines by Moderna and Pfizer/BioNTech.
Arbutus continues to engage in strategic collaborations and partnerships to advance its mission of curing HBV and other chronic infectious diseases. For more detailed information, visit www.arbutusbio.com.

Dr. Sofia, a renowned antiviral drug discovery scientist, co-founded the company and played a important role in developing potential cures for chronic HBV. The company expressed gratitude for his contributions and emphasized its commitment to continue clinical development under new leadership.
