HBV Overview Life - threatening liver infection caused by hepatitis B virus (HBV) Transmitted through body fluids and from mother to child Long - term chronic infection ( cHBV ) leads to higher risk of cirrhosis and/or liver cancer Cause & Symptoms Diagnosis HBsAg detection Additional biomarkers necessary to determine stage of disease Treatments NA therapy – lifelong daily therapy, aimed at reducing HBV DNA and risk of cirrhosis and/or HCC Peg - IFN α – administered weekly; poorly tolerated over 48 weeks of treatment <5% of patients achieve functional cure Rationale Need for finite and more efficacious HBV treatments that further improve long - term outcomes and increase functional cure rate Combination therapy with different MOAs will be required to reduce HBsAg, suppress HBV DNA, and boost immune system Sources for all data on slide: 1 Hepatitis B Fact Sheet, WHO https://www.who.int/news - room/fact - sheets/detail/hepatitis - b ; Hep B Foundation link https://www.hepb.org/what - is - hepatitis - b/what - is - hepb/facts - and - figures/ ; Kowdley et al.

Phase 2a POC Clinical Trial Imdusiran in combination with ongoing NA therapy and short courses of Peg - IFN α - 2 a in cHBV patients IM - PROVE I: POC: Proof of Concept Primary objective : evaluate safety and tolerability of imdusiran in combination with Peg - IFN α - 2a in patients with NA - suppressed cHBV After completing IFN treatment and the 24 - week NA only follow - up period, patients are assessed to stop NA therapy. Those patients that stop NA therapy will be followed for an additional 48 weeks Data presented at EASL Congress 2024 showed that 48 weeks of imdusiran plus 24 weeks of IFN therapy was generally safe, well - tolerated and achieved sustained undetectable HBsAg in 33% of patients after completion of IFN treatment, which were maintained in 100% of these patients 24 weeks after completing imdusiran and IFN treatment Multi - center, open - label Phase 2a 12 © 2024 Arbutus Biopharma, Inc.
