Experimental Hepatitis B Drug Shows Promise for Functional Cure
A new experimental drug for hepatitis B, developed by GSK and Ionis Pharmaceuticals, has shown promising results in achieving a 'functional cure' for some patients. In two international studies, approximately 20% of patients treated with the drug, bepirovirsen, experienced a reduction in the virus to levels manageable by the immune system, allowing them to stop treatment without the virus rebounding. This development marks a significant advancement in hepatitis B treatment, as current therapies require lifelong adherence and do not offer a cure. The drug works by binding to the virus's genetic components, suppressing replication and stimulating the immune system. The findings were presented at a scientific meeting in Barcelona and published in the New England Journal of Medicine.
