What this trial studies

This study investigates the safety and efficacy of undiluted intravenous infusion of I.V.-Hepabig in patients who have undergone liver transplantation due to Hepatitis B-related complications. Participants will receive either undiluted or diluted I.V.-Hepabig injections to assess how well the treatment prevents the recurrence of Hepatitis B. The study aims to provide insights into the optimal dosing and administration of this immunoglobulin therapy in a post-transplant setting.

Who should consider this trial

Good fit: Ideal candidates are adults aged 19 to 65 who have tested positive for Hepatitis B and have a history of liver transplantation due to HBV-related liver disease.

Not a fit: Patients with a history of severe allergic reactions to the treatment components or those with certain co-infections or renal diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the risk of Hepatitis B recurrence in liver transplant patients, improving their long-term health outcomes.

How similar studies have performed: Previous studies have shown promise in using immunoglobulin therapies for Hepatitis B management, suggesting potential success for this approach.
