Aligos Therapeutics Announces Six Preclinical Presentations at the 2025 International HBV Meeting

SOUTH SAN FRANCISCO, Calif., Sept. 03, 2025 (GLOBE NEWSWIRE) -- Aligos Therapeutics, Inc. (Nasdaq: ALGS), a clinical stage biopharmaceutical company focused on improving patient outcomes through best-in-class therapies for liver and viral diseases, today announced six presentations, including three oral presentations, at the 2025 International HBV Meeting, being held September 8 – 12, 2025 in Berlin, Germany.

The company and its collaborators’ commitment to advancing next-generation therapies for liver and viral diseases is reflected in these presentations, with topics spanning novel approaches, molecular strategies, insights into the mechanisms of action of ALG-000184, as well as a new strategy to potentially cure hepatitis delta virus (HDV) infection utilizing a proprietary antisense oligonucleotide (ASO) approach.

“We are pleased to present six preclinical presentations at the International HBV Meeting, that showcase our continued innovation in liver and viral diseases. With the Phase 2 B-Supreme study progressing nicely, we are pleased to present, for the first time, the direct effects of ALG-000184 in reducing HBV cccDNA in a preclinical setting. These data help corroborate the clinical observations of HBV antigen reductions seen in patients with chronic HBV infection treated with ALG-000184 monotherapy to date and are a direct indication that ALG-000184 can invoke the secondary mechanism of CAM-Es,” stated Lawrence Blatt, PhD, MBA, Chairman, President, and Chief Executive Officer of Aligos Therapeutics. “While we remain committed to the continued development of our best/first-in-class CAM-E ALG-000184 for chronic HBV infection, we are pleased to broaden our pipeline with the presentation of our discovery stage ASO program for the treatment of HDV. HDV coinfection with HBV leads to more rapid disease progression and our ASO uniquely targets the destruction of the viral genome, making this mechanism uniquely suited towards a potential HDV cure. Ongoing work will be aimed at selection of the HDV-targeted ASO clinical development candidate.”
