EXHIBIT 99.1 Aligos Therapeutics Reports Recent Business Progress and Third Quarter 2025 Financial Results SOUTH SAN FRANCISCO, Calif., Nov. 06, 2025 (GLOBE NEWSWIRE) -- Aligos Therapeutics, Inc. (Nasdaq: ALGS, “Aligos”), a clinical stage biotechnology company focused on improving patient outcomes through best-in- class therapies for liver and viral diseases, today reported recent business progress and financial results for the third quarter 2025. “Our Phase 2 B-SUPREME study of pevifoscorvir sodium (pevy) is enrolling nicely, with subjects dosed across a number of countries, including the U.S., China, Hong Kong, and Canada,” stated Lawrence Blatt, Ph.D., M.B.A., Chairman, President, and Chief Executive Officer of Aligos Therapeutics. “We are pleased with the progress to date and look forward to interim readouts in 2026. Importantly, we look forward to sharing additional pevy data next week at AASLD’s The Liver Meeting®. We maintain our enthusiasm regarding the potential for pevy as well as our entire development pipeline, including ALG-055009, which is in continued discussions with potential partners for obesity and MASH.” Recent Business Progress Pipeline Updates Pevifoscorvir sodium: Potential first-/best-in-class small molecule CAM-E for chronic hepatitis B virus (HBV) infection The Phase 2 B-SUPREME study (NCT06963710) of pevifoscorvir sodium in subjects with chronic HBV infection dosed its first patient in August 2025. The study is designed as a randomized, double-blind, active-controlled multicenter study evaluating the safety and efficacy of pevifoscorvir sodium monotherapy compared with tenofovir disoproxil fumarate in approximately 200 untreated HBeAg+ or HBeAg- adult subjects with chronic HBV infection for 48 weeks. The primary endpoint in the HBeAg+ subjects is HBV DNA <LLOQ (10 IU/mL, target detected [TD] or target not detected [TND]) and the primary endpoint in the HBeAg- subjects is HBV DNA <LLOQ (10 IU/mL, target not detected [TND]). The study is also evaluating safety, pharmacokinetics, and other secondary and exploratory HBV biomarkers, including reductions in HBV antigens and other markers of HBV infection. Interim data are projected in 1H and 2H 2026 and topline data are anticipated in 2027. 96-weeks of dosing have been completed in the Phase 1 study (NCT04536337) and data readouts, including post-treatment data, will be presented at The Liver Meeting® 2025 in November 2025. Eight abstracts were accepted for presentation (four for pevifoscorvir sodium), including one oral presentation on the Phase 1 monotherapy study of pevifoscorvir sodium. ALG-055009: Potential best-in-class small molecule THR-β for obesity, MASH THR-β agonists under investigation from other companies have demonstrated significant enhancement in weight loss when administered in combination with incretin receptor agonists (RAs) for the treatment of obesity. Recently generated preclinical data combining ALG-055009 with incretin RAs in a diet-induced obese (DIO) mouse model exhibited profound synergistic effects in body weight loss when used in combination with semaglutide or tirzepatide. The combination therapy also demonstrated enhanced antihyperlipidemic effects as compared to monotherapy. These data are expected to be presented at a future scientific conference. Evaluation of a variety of options to fund continued development, including potential out-licensing is ongoing. Financial Results for the Third Quarter 2025 Cash, cash equivalents and investments totaled $99.1 million as of September 30, 2025, compared with $56.9 million as of December 31, 2024. Our cash, cash equivalents and investments are expected to provide sufficient funding of planned operations into the third quarter of 2026.
