– Pipeline reprioritization emphasizes NASH and COVID-19 assets, ALG-055009 and ALG-097558, plus key ongoing collaborations, including the Merck & Co. (MSD) programs in NASH – – Overall workforce reduction (attrition and reduction in force) of approximately 25% since beginning of January 2022 – SOUTH SAN FRANCISCO, Calif., Feb. 08, 2023 (GLOBE NEWSWIRE) -- Aligos Therapeutics, Inc. (Nasdaq: ALGS), a clinical stage biopharmaceutical company focused on developing novel therapeutics to address unmet medical needs in NASH and viral diseases, today announced a portfolio reprioritization. Aligos’ highest priorities will be focused on rapid advancement of its clinical NASH (ALG-055009) and COVID-19 (ALG-097558) programs as well as maintaining its ongoing NASH oligonucleotide research collaborations with Merck & Co. (MSD outside the U.S. and Canada). Additionally, the Company plans to complete the ≤48-week (ALG-000184) and single ascending dose (ALG-125755) cohorts for its two chronic hepatitis B programs and continue to invest in selected research programs and collaborations with external research organizations. This portfolio reprioritization is being accompanied by a reduction of the Company’s current workforce of approximately 10% and, combined with careful workforce management, including employee attrition and targeted hiring, has resulted in an overall workforce reduction of approximately 25% since the beginning of January 2022. As a result of the portfolio reprioritization, realignment of its workforce, and other cost-saving measures, the Company expects to maintain a strong balance sheet and extend its projected cash runway to the end of 2024. The Company expects to report Q4 and 2022 year-end financial results as well as provide guidance regarding the amount of anticipated one-time charges related to the reprioritization, which we expect to record in Q1 2023, in mid-March 2023. “With such a diverse clinical portfolio, including four drug candidates in or near the clinic, as well as maintaining a strong discovery engine, where we continue to support multiple research collaborations, we determined that Aligos would be best positioned to achieve its business objectives by taking action now to streamline operations, reprioritize its portfolio, and implement certain cost-saving measures, including a reduction in force,” said Lawrence Blatt, Ph.D., MBA, CEO and Chairman of the Board at Aligos. “I would like to express my sincere gratitude to the employees who are being affected by this reprioritization. We are grateful for their dedicated service and contributions to Aligos’ mission.” Dr. Blatt further noted that, “After taking these steps, we can affirm that we are committed to advancing our THR-β NASH drug candidate, ALG-055009, which appears differentiated vs. frontrunner drugs in its class, as well as our differentiated pan-coronavirus drug candidate, ALG-097558. Based on the early activity and the emerging pro have observed for these programs, we believe they are well positioned to fulfill our mission to leverage our expertise in liver disease and antiviral agents to develop targeted, potentially best-in-class treatments for NASH and viral diseases.” Selected Pipeline Review Going forward, Aligos will emphasize its programs in nonalcoholic steatohepatitis (NASH) and COVID-19. NASH ALG-055009 – the Company’s THR-β agonist in development for NASH is expected to complete an ongoing Phase 1 study in H1 2023. The Company has already initiated Phase 2-enabling activities, including GLP toxicology studies, and it is planning a Phase 2 filing by the end of 2023. COVID-19 ALG-097558 – Aligos’ 3-chymotrypsin-like protease (3CLpro) inhibitor, a potent pan-coronavirus protease inhibitor candidate that does not require ritonavir boosting, is expected to complete Phase 1-enabling activities in H1 2023. The company aims to complete a Phase 1 study evaluating single and multiple ascending doses in healthy volunteers in H2 2023 to enable the start of a Phase 2 study by the end of 2023. Chronic Hepatitis B (CHB) ALG-000184 – The Phase 1b study of Aligos’ capsid assembly modulator-empty (CAM-E) is expected to complete ongoing cohorts evaluating ≤48 weeks of treatment. Emerging data from these cohorts will be presented at scientific conferences throughout the year. Aligos plans to review next steps based on these data. ALG-125755 – As part of the portfolio reprioritization, Aligos will continue to evaluate its siRNA candidate in a Phase 1 single ascending dose (SAD) study in CHB patients and expects to present emerging data at scientific conferences throughout the year. Aligos plans to review next steps for this program based on these expected data. Discovery Engine and General Corporate Operations Aligos plans to continue to support its collaboration agreements, including the agreement with Merck & Co. to develop oligonucleotide candidates to address NASH. Collaborations with the National Institutes of Health (NIH) and the National Institute of Allergy and Infectious Disease (NIAID)’s Antiviral Drug Discovery (AViDD) Centers for Pathogens of Pandemic Concern program through the Metropolitan AntiViral Drug Accelerator (MAVDA) consortium, KU Leuven, the Rega Institute, and the Leuven Centre for Drug Design and Discovery remain unchanged. Aligos’ two South San Francisco locations will be consolidated into the Company’s headquarters location. The Leuven, Belgium and the Shanghai, China sites are expected to remain in operation.
