SOUTH SAN FRANCISCO, Calif., May 08, 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 positive data from eight presentations at the European Association for the Study of the Liver (EASL) Congress 2025, being held May 7 – 10, 2025 in Amsterdam, Netherlands.
“We are pleased to have eight presentations at this year’s EASL Congress from programs across our pipeline,” stated Lawrence Blatt, PhD, MBA, Chairman, President, & CEO of Aligos Therapeutics. “In particular, we are excited to share an update on the 96-week data from the monotherapy cohort receiving 300 mg ALG-000184. All subjects in both the HBeAg
+
and HBeAg
-
cohorts have achieved HBV DNA viral suppression < LLOQ (10 IU/mL) and continue to demonstrate sustained log
10
reductions in viral antigens such as HBcrAg. These data further strengthen our belief that ALG-000184 is a first-/best-in-class asset with the potential to improve patient outcomes. Additionally, we will present biomarker and subgroup analyses from the Phase 2a HERALD study. These data continue to demonstrate the best-in-class potential of ALG-055009 across the cardio-metabolic space.”
Two presentations highlight the continued potent antiviral activity of ALG-000184 for chronic hepatitis B virus (HBV) infection in both untreated HBeAg
+
and HBeAg
-
subjects, demonstrating the potential for the molecule to become first-line therapy for chronic suppression and the backbone for regimens aimed at functional cure.
In HBeAg
+
subjects with a very high mean HBV DNA level of 8.0 log
10
IU/mL at baseline, all experienced profound and persistent HBV DNA reductions after receiving an oral daily dose of 300 mg ALG-000184 monotherapy. At Week 48, 6 of 10 subjects (60%) achieved HBV DNA < LLOQ (10 IU/mL, target detected or target not detected). With treatment extension, this rate increased to 9 of 9 subjects (100%) at Week 96. Additionally, HBV DNA level continuously declined to < LLOQ (target not detected, <4.29 IU/mL) in 5 of 9 subjects at Week 96.
In HBeAg
-
subjects, all 11 (100%) had rapid decline in HBV DNA levels and achieved sustained HBV DNA suppression (HBV DNA < LLOQ, target detected or target not detected) by Week 24. The HBV DNA suppression level was maintained in the ALG-000184 monotherapy cohort for up to 96 weeks, with further decline in HBV DNA to < LLOQ, target not detected, observed in all subjects (8/8) at Week 96.
Importantly, no viral breakthrough was observed in any chronic HBV infection subjects receiving ALG-000184 monotherapy for up to 96 weeks. The resistant analysis reported no known CAM resistant mutations had been identified with ALG-000184 monotherapy.
HBV RNA level achieved < LLOQ (10 copies/mL) in all HBeAg
+
and HBeAg
-
subjects by Week 52 and Week 8, respectively. Furthermore, concurrent multi-log
10
reductions in HBV antigens (HBsAg, HBeAg, and HBcrAg) in HBeAg
+
subjects and HBcrAg decline in HBeAg
-
subjects were observed, suggesting the potential inhibition of cccDNA establishment by CAM-E 2
nd
mechanism of action of ALG-000184.
A favorable tolerability profile has been demonstrated in untreated HBeAg
+
and HBeAg
-
subjects receiving 300 mg ALG-000184 for up to 96 weeks.
Additionally, two presentations will showcase the best-in-class potential of ALG-055009, a purpose built THR-β agonist discovered by Aligos scientists. As previously presented at AASLD’s The Liver Meeting in 2024, 12-weeks of once daily ALG-055009 treatment in MASH patients met the primary endpoint, with robust reductions in liver fat content at Week 12. Doses of 0.5 mg to 0.9 mg ALG-055009 demonstrated statistically significant reductions in liver fat at Week 12, with placebo-adjusted median relative reductions up to 46.2% as measured by MRI-PDFF. Eighteen subjects who were on stable GLP-1 agonist therapy qualified for enrollment in the study, with liver fat content meeting the inclusion criteria of ≥10% at baseline as measured by MRI-PDFF. Notably, 11/14 subjects on stable GLP-1 agonists treated with ALG-055009 had liver fat decreases, whereas 4/4 subjects on stable GLP-1 agonists treated with placebo had increases in liver fat over the 12-week dosing period. Treatment with ALG-055009 was well-tolerated, with rates of gastrointestinal-related AEs similar to placebo.
New data being presented at the EASL congress will demonstrate substantial, dose-dependent reductions in liver fat were observed across all key subgroups with 12 weeks of once daily ALG-055009 treatment. In addition, statistically significant improvements in atherogenic lipids were achieved with 12 weeks of ALG-055009 treatment. Reductions in lipids/lipoproteins were observed even in the context of stable GLP-1 agonist or statin use. This data suggests an added benefit of ALG-055009 for patients at risk for cardiovascular disease in addition to the previously reported liver fat lowering properties in a MASLD/MASH population.
