Summary
This early-stage study tested a new treatment approach for adults with chronic hepatitis B or D. Twenty participants received two medications in sequence: P1101 (a type of interferon) followed by an anti-PD1 drug. The main goal was to check safety and tolerability, while also looking for signs that the virus might be cleared, such as loss of hepatitis B surface antigen (HBsAg). The study is now complete.
