Columbia University·interventional·Posted Jun 22, 2010·Updated Aug 10, 2021

In Brief

A Phase 2 clinical trial evaluating Adefovir dipivoxil and hepatitis B vaccination for Hepatitis B and Liver Transplantation. Completed, enrolled 16 participants across 1 site.

Detailed Summary

The primary purpose of this study is to evaluate the efficacy of adefovir (ADV) in preventing de novo Hepatitis B in patients who receive Hepatitis B core antibody (HBcAb) positive grafts but who are not Hepatitis B Surface antigen (HBsAg) positive prior to transplant (Hepatitis B naive patients). The second objective is to evaluate the efficacy of accelerated vaccination with Hepatitis B in inducing innate immunity, thereby obviating the need for life-long antiviral therapy.
