U.S. FDA approves hepatitis B drug that offers some patients a functional cure
A hepatitis B drug used alongside existing antivirals is aimed at ending years of treatment for some adults, though most trial patients did not reach that result. In two placebo-controlled trials across 29 countries, 19% had no detectable virus or surface protein at least 24 weeks after stopping treatment, versus none on placebo. The label carries a boxed warning for liver flares and low platelets, excludes people with cirrhosis, and requires weekly blood checks.
