SOUTH SAN FRANCISCO, Calif., Feb. 03, 2021 (GLOBE NEWSWIRE) -- Aligos Therapeutics, Inc. (NASDAQ:ALGS), a clinical stage biopharmaceutical company focused on developing novel therapeutics to address unmet medical needs in viral and liver diseases, today announced that the company will deliver four poster presentations at the 30th Annual Conference of the Asian Pacific Association for the Study of the Liver (APASL), taking place virtually from February 4 through February 6, 2021.

"We are proud to show progress for two of our clinical candidates from our chronic hepatitis B portfolio," said Aligos CEO Lawrence Blatt, Ph.D., MBA. "Both candidates are currently being evaluated in Phase 1a/b umbrella studies where we will evaluate each for antiviral activity in CHB patients following demonstration of safety and tolerability in healthy volunteers. These trials are part of a larger plan to develop highly effective treatments using combinations of multiple novel drugs from our portfolio. We look forward to advancing our other lead candidates targeting other viral mechanisms of action into the clinic alongside ALG-010133 and ALG-000184."

Three of the presentations highlight encouraging data from Aligos' two most advanced CHB candidates for development toward a combination therapy for chronic hepatitis B (CHB): STOPS™ (ALG-010133), a proprietary oligonucleotide designed to inhibit hepatitis B virus (HBV) S-antigen (or HBsAg) replication, and ALG-000184, a capsid assembly modulator (CAM), designed to inhibit HBV replication.

The first presentation, titled "Preclinical Efficacy and Pharmacokinetics of ALG-010133, an S-Antigen Transport-inhibiting Oligonucleotide Polymers (STOPS) for the Treatment of Chronic Hepatitis B (CHB)", demonstrated that Aligos' lead STOPS candidate inhibited S-antigen release from cells in several lines of human hepatocytes. In vivo, ALG-010133 demonstrated high, rapid and sustained exposure in the liver following single subcutaneous injections given to nonclinical species, predicting once-weekly dosing in humans. Further, a nonclinical multiple dosing study in which animals were given three weekly subcutaneous doses demonstrated sufficient concentrations in the liver sufficient for projected efficacy in human CHB patients. Together, the combination of excellent in vitro efficacy and a favorable pharmacokinetic profile in vivo has justified ALG-010133's progression to a Phase 1a/b trial for evaluation as a potential treatment for CHB.

A second presentation, "Safety, tolerability and pharmacokinetics of single ascending doses of ALG-000184, a Class II Capsid Assembly Modulator for the treatment of Chronic Hepatitis B (CHB), in healthy volunteers (HV)", outlined preliminary data supporting further evaluation of Aligos' small molecule candidate ALG-000184 in healthy volunteers and in CHB patients, as planned in the ongoing Phase 1a/b trial. At single oral doses of up to 500 mg, ALG-000184 was safe, well-tolerated and demonstrated a linear pharmacokinetic profile supporting once-daily oral dosing. Doses of 100 mg or higher resulted in plasma concentrations of active compound that are projected to result in antiviral activity in CHB patients.

Two other poster presentations entitled "Excellent preclinical characteristics of ALG-000184, a prodrug of the HBV capsid assembly modulator ALG-001075" and "ALG-020572, a next generation hepatitis B virus (HBV) antisense oligonucleotide (ASO) with bridged nucleic acid chemistry, has a significantly improved preclinical profile" highlight the nonclinical characteristics of ALG-000184 and its parent compound, ALG-001075, and ALG-020572, Aligos' ASO candidate for chronic hepatitis B that significantly improves upon other ASOs in terms of nonclinical safety and efficacy.
