What this trial studies

This study evaluates the safety and efficacy of Sintilimab, a PD-1 antibody, in combination with Peg-IFNα-2b for patients with chronic hepatitis B who have been virologically suppressed by nucleos(t)ide analogs. Participants must have previously received Peg-IFNα therapy and show limited response to it. The study aims to determine if this sequential treatment can improve patient outcomes. It is a prospective interventional study focusing on a specific patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 with chronic hepatitis B who have been virologically suppressed and previously treated with Peg-IFNα.

Not a fit: Patients with cirrhosis, significant blood count abnormalities, or other active infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective therapy option for patients with chronic hepatitis B.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in using combination therapies for chronic hepatitis B.
