Characterizing immune and viral responses in chronic Hepatitis D patients treated with Bulevirtide

Immunological and Virological Characterization of Patients With Chronic HBV-HDV Infection: Association With Disease Outcomes and Response to Bulevirtide Treatment

Observational Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico · NCT06504485

This study is trying to see how well Bulevirtide treatment works for people with chronic Hepatitis D and how their immune system responds over time.

What this trial studies

This observational study aims to characterize the immunological and virological responses of patients with chronic Hepatitis D virus (HDV) infection who are being treated with Bulevirtide. It involves a collaboration between several institutions in Italy, focusing on understanding the immune response and disease progression in patients co-infected with Hepatitis B virus (HBV) and HDV. The study will analyze the role of CD4 and CD8 T cells in the context of chronic HDV infection, which is poorly understood. Participants will be monitored for their responses to the treatment over time.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with chronic HDV infection confirmed by specific viral markers.

Not a fit: Patients co-infected with other viruses such as HCV or HIV, or those on immunosuppressive therapies, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of chronic Hepatitis D infections, potentially enhancing treatment outcomes.

How similar studies have performed: While there is ongoing research in the field of Hepatitis D, this specific approach focusing on the immune response to Bulevirtide treatment is relatively novel.
