Data demonstrates a 7-day treatment regimen with the pan-coronavirus protease inhibitor ALG-097558 was well tolerated and does not require ritonavir boosting

SOUTH SAN FRANCISCO, CA, USA I April 25, 2024 I Aligos Therapeutics, Inc. (Nasdaq: ALGS, “Aligos”), a clinical stage biopharmaceutical company focused on developing novel therapeutics to address unmet medical needs in liver and viral diseases, today announced an ePoster flash session presentation at the 34th European Society of Clinical Microbiology and Infectious Diseases (ESCMID) 2024, being held April 27-30, 2024 in Barcelona, Spain.

The presentation highlights ALG-097558 Phase 1 data showing that single (up to 2000 mg) and multiple (up to 800 mg Q12 for 7 days) doses of this potent, pan-coronavirus protease inhibitor were well tolerated in healthy volunteers with a PK profile supporting twice daily ritonavir-free dosing without a food effect.

“We are pleased to present these ALG-097558 data, which further highlight the best-in-class potential of this pan-coronavirus protease inhibitor and its substantial differentiation versus current standard of care coronavirus antiviral drugs like nirmatrelvir/ritonavir (PAXLOVIDTM),” said Lawrence Blatt, Ph.D., MBA, Chairman, President, and Chief Executive Officer at Aligos Therapeutics. “These data further demonstrate that Aligos has developed a robust clinical pipeline of three potentially best-in-class drug candidates. We look forward to continuing to advance ALG-097558 for current and potential future pandemics with the financial support of various external funding sources, including government agencies.”

Details of the presentation are as follows:

  • ePoster Flash Session Presentation Title: Safety and pharmacokinetics of single and multiple ascending doses of ALG-097558, a pan-coronavirus proteaseinhibitor, in healthy volunteers
    • Presented by Denisa Wilkes, MD, MSc, CPM, Medical Director, Hammersmith Medicines Research
    • April 28, 2024 at 8:30am CEST
