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.

Net loss for the three months ended September 30, 2025 was $31.5 million or basic and diluted net loss per common share of $(3.04), compared to net loss of $19.3 million or basic and diluted net loss per common share of $(3.07) for the three months ended September 30, 2024.

Research and development (R&D) expenses for the three months ended September 30, 2025 were $23.9 million, compared with $16.8 million for the same period of 2024. The increase was primarily due to an increase in third-party expenses for the pevifoscorvir sodium Phase 2a clinical trial. Total R&D stock-based compensation expense incurred for the three months ended September 30, 2025 was $0.8 million, compared with $1.2 million for the same period of 2024.

General and administrative (G&A) expenses for the three months ended September 30, 2025 were $5.2 million, compared with $4.6 million for the same period of 2024. The increase in G&A expenses for this comparative period is primarily due to an increase in legal and other related expenses. Total G&A stock-based compensation expense incurred for the three months ended September 30, 2025 was $0.7 million, compared with $0.9 million for the same period of 2024.

Interest and other income, net, was income of $1.1 million for each of the three months ended September 30, 2025 and September 30, 2024.

Change in fair value of 2023 common warrants for the three months ended September 30, 2025 was a loss of $4.2 million compared with a loss of $0.1 million for the same period of 2024.
