Summary of Aligos Therapeutics Conference Call Company Overview - Company: Aligos Therapeutics - Industry: Biotechnology, focusing on liver and viral diseases - Mission: To improve patient outcomes by developing best-in-class therapies for chronic hepatitis B virus (HBV) infection and metabolic dysfunction-associated steatohepatitis (MASH) [1][34] Key Drug: ALG-000184 - Type: Capsid assembly modulator for HBV - Discovery: Originated from research by Professor Raymond Schinazi at Emory University, known for developing several antiviral drugs [3][4] - Mechanism of Action: - Binds to HBV core protein, preventing encapsulation of pregenomic RNA, thus blocking DNA production [4][16] - Evokes a secondary mechanism that reduces CCC DNA, a long-lived viral reservoir [6][17] - Pharmacokinetics: - Improved from 5% to 80% oral bioavailability [5] - Demonstrated significant reductions in HBV DNA and surface antigens in clinical studies [6][7] Clinical Data and Efficacy - Phase 1B Study: - 96-week data showed no emergence of drug resistance, allowing for potential monotherapy [10][11] - Achieved 100% of E antigen negative patients below 10 international units of HBV DNA at week 48, compared to historical data of around 20% for standard treatments [21][22] - Endpoints: - Primary endpoint for monotherapy is chronic suppression of HBV DNA [18][19] - Importance of achieving below 10 international units for better long-term outcomes, including reduced liver cancer progression [20][22] Future Development: B Supreme Study - Design: Ongoing phase 2 study comparing ALG-000184 with TDF in both E positive and E negative patients [24][25] - Goals: - Superiority in HBV DNA endpoints and antigen reductions [27][28] - Paired biopsies to quantify integration events and CCC DNA levels [28] Competitive Landscape - Positioning: ALG-000184 aims to become the standard of care for chronic HBV suppression and a backbone for functional cure regimens [30][31] - Antisense Oligonucleotide Program: Aligos is developing its own ASO program to complement ALG-000184, enhancing potential treatment options [31] Other Drug: ALG-055009 for MASH - Mechanism: Targets metabolic dysfunction in liver disease, showing significant fat reduction in phase 2A studies [36][37] - Combination Potential: Compatible with GLP-1 therapies, enhancing fat reduction and weight loss [38][39] Upcoming Milestones - 2025-2027 Timeline: - Final data from the 96-week study of ALG-000184 to be presented at AASLD [41] - Interim readout from the B Supreme study in 2026 [41] - Partnership announcement for ALG-055009 expected early next year [42] Conclusion - Aligos Therapeutics is positioned to address significant unmet needs in the treatment of HBV and MASH, with promising clinical data and a robust pipeline aimed at improving patient outcomes in these areas [40][43]
