• Over 50 pharmaceutical companies are actively developing 55+ pipeline therapies for chronic hepatitis B virus (HBV) infection, signaling a robust research landscape aimed at achieving functional cures beyond current suppressive treatments.
• Promising candidates include Pradefovir (Ligand Pharmaceuticals) in Phase III and RG6346 (Dicerna/Roche) in Phase II, with the latter demonstrating over 99.9% reduction in circulating HBsAg in preclinical models.
• GlaxoSmithKline and Vir Biotechnology are pioneering combination approaches, with GSK evaluating sequential therapy of ASO compound (GSK3228836) and CHB-TI (GSK3528869A) to potentially enhance efficacy over monotherapy in chronic HBV patients.
