The FDA removed the clinical hold on Arbutus Biopharma's IND for AB-101, an oral PD-L1 inhibitor for chronic hepatitis B, allowing renewed U.S. clinical development. Phase 1a/1b data showed AB-101 was generally well-tolerated, with high receptor occupancy in seven cHBV patients and HBsAg decline in two patients at the 30mg dose.
