Combining PD-1 antibody with Peg-IFNα for treating chronic hepatitis B

The Safety and Efficacy of PD-1 Antibody Combined With Pegylated Interferon-α Therapy to Promote the Clinical Cure in Nucleoside (Acid) Analogues-suppressed Chronic Hepatitis B Patients: A Protocol for the Prospective Pilot Study

Not applicable Interventional Beijing 302 Hospital · NCT06357806

This study is testing if combining a new antibody treatment with an existing medication can help people with chronic hepatitis B who are already on other treatments feel better and manage their virus more effectively.

What this trial studies

This clinical trial evaluates the efficacy and safety of Sintilimab, a PD-1 antibody, in combination with Peg-IFNα-2b for patients with chronic hepatitis B who are currently on nucleos(t)ide analogs (NAs) treatment. It is a prospective, open-label, randomized controlled study that aims to determine if this combination therapy can improve patient outcomes. Participants will be monitored for their response to the treatment over a specified period, focusing on viral suppression and safety profiles.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 with chronic hepatitis B who have been on stable NAs treatment for at least one year.

Not a fit: Patients with cirrhosis, significant blood count abnormalities, or those with a history of hepatocellular carcinoma may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective option for managing chronic hepatitis B, potentially leading to better viral control and improved liver health.

How similar studies have performed: While this approach is innovative, similar studies combining immune checkpoint inhibitors with antiviral therapies have shown promise in other viral infections, suggesting potential for success.
