Efficacy of Sofosbuvir and Daclatasvir in Patients With Fibrosing Cholestatic Hepatitis C After Liver Transplantation.

BACKGROUND & AIMS: Fibrosing cholestatic hepatitis (FCH) is a life-threatening disorder that develops in patients with recurrent hepatitis C virus (HCV) infection after liver transplantation. Until recently, therapeutic options have been limited. We evaluated the efficacy and safety of sofosbuvir- and daclatasvir-based regimens.

METHODS

We analyzed data from 23 patients with FCH who participated in a prospective cohort study in France and Belgium of the effects of antiviral agents in patients with recurrence of HCV infection after liver transplantation, from October 2013 through April 2014. Most of the patients had genotype 1 infections that had not responded to previous treatment; 4 patients also were infected with human immunodeficiency virus. Eight patients (37%) had ascites and 15 patients (65%) had bilirubin levels greater than 100 mmol/L; their median serum level of HCV RNA was 7 log IU/mL. The median time between transplantation and treatment initiation was 5 months. Subjects were given either sofosbuvir and daclatasvir (n = 15) or sofosbuvir and ribavirin (n = 8) for 24 weeks. The primary outcome was complete clinical response (survival without re-transplantation, bilirubin level <34 μmol/L, and no ascites or hepatic encephalopathy 36 weeks after treatment began).

RESULTS

All patients survived, without re-transplantation, until week 36. Rapid and dramatic improvements in clinical status were observed. The patients' median bilirubin concentration decreased from 122 μmol/L at baseline to a normal value at week 12 of treatment. Twenty-two patients (96%) had a complete clinical response at week 36. Despite the low rate of rapid virologic response, 22 patients (96%) achieved a sustained virologic response at week 12. The only relapse of HCV infection occurred in a patient with human immunodeficiency virus infection who received sofosbuvir and ribavirin. Tolerance was satisfactory, with no grade 3 or 4 adverse events related to sofosbuvir or daclatasvir and no significant interactions among drugs.

CONCLUSIONS

Sofosbuvir therapy with daclatasvir or ribavirin leads to major clinical improvement and high rates of sustained virologic response at week 12 in most patients with recurrence of HCV infection and FCH after liver transplantation. ClinicalTrial.gov no: NCT01944527.
