NCT05683548

Brief Summary

The goal of this compassionate access program is to provide early access to REP 2139-Mg for patients with HBV mono-infection or HBV / HDV co-infection who either have advanced (decompensated) cirrhosis or who have failed to response to other other antiviral agents either approved or under development and who are in danger of progressing to decompensated cirrhosis. This compassionate access program will provide access to a once weekly regimen of subcutaneously (SC) administered REP 2139-Mg for a period of 48 weeks with the goal of achieving functional cure of HDV and or HBV, with the reversal of liver disease in the absence of antiviral therapy. The safety, tolerability and efficacy of SC REP 2139-Mg will be monitored during and after therapy
