ABUS reports interim phase-1 data on AB-729 for HBV: https://finance.yahoo.com/news/arbutus-announces-positive-preliminary-phase-200510591.html AB-729 is an injected RNAi agent that targets HBsAg. The data reported today are from a single subcutaneous dose. After 29 days, the mean reduction in HBsAg was: 0.2 logs in the 60mg cohort; and 0.8 logs in the 180mg cohort. After 12 weeks, the mean reduction in HBsAg was: n/a in the 60mg cohort; and -1.0 logs in the 180mg cohort. Whether HBsAg is the right target to be hitting is somewhat controversial—see, for instance, #msg-152274693.
