Dosing of ALG-020572 (ASO) in healthy volunteers underway

Enrollment in first 2 STOPS cohorts (120, 200 mg) complete; enrollment in 3rd cohort (400 mg) underway

Clinical trial application (CTA) filed for 1st NASH drug candidate, ALG-055009, a THR-beta agonist

SOUTH SAN FRANCISCO, Calif., Nov. 04, 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 reported recent business progress and financial results for the third quarter ended, September 30, 2021.

“The last quarter has been busy and productive for Aligos,” said Lawrence Blatt, PhD, MBA, Chairman and CEO of Aligos. “We now have three of our four drug candidates targeting chronic hepatitis B, each of which has a distinct additive or synergistic mechanism of action, dosing in the clinic. Additionally, enrollment of CHB patients has improved, and our planned safety and viral kinetic data readout for the first three cohorts of STOPS™ remains on track for the first half of 2022. In parallel to this effort, the Aligos team was able to successfully file the CTA for our first drug candidate for the treatment of NASH, ALG-055009. The progress made by our team over the last quarter positions us well to be able to deliver key data for multiple programs in 2022.”

Recent Business Progress
Aligos’ portfolio of drug candidates has continued to advance during the quarter with the following accomplishments achieved:

• S-Antigen Transport-Inhibiting Oligonucleotide Polymers (STOPS; ALG-010133)
  • Our Phase 1b dose range finding trial (NCT04485663) evaluating subjects with CHB is ongoing. Enrollment in the second cohort, evaluating the 200 mg dose level, was completed and enrollment in the third cohort, evaluating a 400 mg dose level, is now underway. We remain on track to unblind and share topline safety and viral kinetic data, including Hepatitis B S-antigen (HBsAg) data, from the first three cohorts in the first half of 2022.
• Capsid Assembly Modulator (CAM; ALG-000184)
  • Our Phase 1b dose range finding trial (NCT04536337) evaluating CHB subjects is ongoing. Enrollment of hepatitis B E-antigen (HBeAg) negative subjects into 50 and 100 mg dose cohorts is now complete. Enrollment of a 10 mg dose cohort is underway to determine the minimum efficacious dose. A cohort of HBeAg-positive CHB patients receiving a 100 mg dose for 28 days has also been fully enrolled in China.
  • A poster describing the safety, PK, and antiviral activity of the 50 and 100 mg doses of ALG-000184 given for 28 days in HBeAg-negative CHB subjects will be presented at The Liver Meeting^® (American Association for the Study of Liver Disease) later this month.
• Antisense Oligonucleotide (ASO; ALG-020572)
  • Our Phase 1a/b multi-part study (NCT05001022) evaluating ALG-020572 in healthy volunteers and CHB subjects has recently commenced. Enrollment of healthy volunteers in the single ascending dose (SAD) portion of the study was initiated in October 2021.
• Nonalcoholic Steatohepatitis (NASH; ALG-055009, a thyroid hormone receptor beta (THR-B) agonist)
  • The CTA for ALG-055009 was filed in France to enable a SAD and multiple ascending dose (MAD) study in healthy volunteers and hyperlipidemic subjects, respectively.
  • Study startup activities remain on track with dosing in healthy volunteers expected to begin in the fourth quarter of 2021.

Aligos has a broad CHB portfolio that targets different clinically validated mechanisms of action in the hepatitis B virus life cycle. The portfolio includes a STOPS molecule, ALG-000184, a class II CAM, ALG-010133, ALG-020572, an ASO, and ALG-020755, an siRNA drug candidate. The properties of these candidates indicate that their use in combination could yield potentially best-in-class treatment regimens that may achieve higher rates of functional cure than current standard of care. For each of these drug candidates, Aligos plans to initially establish proof of concept as monotherapy in Phase 1 dose range finding trials before evaluating them in combination in subsequent trials.

Financial Results for the Third Quarter 2021
Net losses for the three months ended September 30, 2021 were $33.1 million or basic and diluted net loss per common share of $(0.78) compared to net losses of $33.3 million or basic and diluted net loss per common share of $(11.00) for the three months ended September 30, 2020.

Research and development (R&D) expenses for the three months ended September 30, 2021, were $28.1 million compared with $17.3 million for the same period of 2020. The increase in R&D expenses for this comparative period is primarily attributable to increased expenses related to the Company’s continued development and manufacturing of ALG-010133, ALG-000184 and ALG-020572 clinical trial activities, as well as increases in salaries and employee-related expenses and preclinical programs. Total R&D stock-based compensation expense incurred for the three months ended September 30, 2021, was $1.9 million compared with $0.3 million for the same period for 2020.

General and administrative (G&A) expenses for the three months ended September 30, 2021, were $6.5 million compared with $4.2 million for the same period of 2020. The increase in G&A expenses for this comparative period is primarily attributable to higher employee-related costs associated with the growth of the Company’s operations and additional professional, legal and consulting services related to being a public company. Total G&A stock-based compensation expense incurred for the three months ended September 30, 2021, was $1.7 million compared with $0.7 million for the same period for 2020.

Cash, cash equivalents and investments totaled $242.7 million as of September 30, 2021 compared with $243.5 million as of December 31, 2020.
