Emerging concepts in alcoholic hepatitis - rationale of the 308 study, organ support and transplantation

Severe Alcoholic Hepatitis (sAH) is associated with a poor prognosis. There is no proven effective treatment for sAH, which is why early transplantation has been increasingly discussed. Hepatoblastoma-derived C3A cells express anti-inflammatory proteins and growth factors and were tested in an extracorporeal liver treatment (ELAD®) study to establish their effect on survival for subjects with sAH. 

Adults with sAH, bilirubin ≥8 mg/dL, Maddrey’s Discriminant Function (DF) ≥32 and Model for End-Stage Liver Disease (MELD) score ≤35, were randomized to receive standard of care (SOC) only or 3-5 days of continuous ELAD® treatment plus SOC. After a minimum follow-up of 91 days, overall survival (OS) was assessed using a Kaplan-Meier survival analysis. A total of 203 subjects were enrolled (96 ELAD® and 107 SOC) at 40 sites worldwide.

Comparison of baseline characteristics showed no significant differences between groups and within subgroups. There was no significant difference in serious adverse events between the two groups. In an analysis of the intent-to-treat (ITT) population, there was no difference in OS (51.0% vs 49.5%). The study failed its primary and secondary endpoint in a population with AAH and with a MELD ranging from 18-35 and no upper age limit. In the pre-specified analysis of subjects with MELD <28 (n=120), ELAD® was associated with a trend toward higher OS at 91 days (68.6% vs 53.6%, p=0.077). Regression analysis identified high creatinine and INR, but not bilirubin, as the MELD components predicting negative outcomes with ELAD®. A new trial investigating a potential benefit of ELAD® in younger subjects with sufficient renal function and less severe coagulopathy has been initiated.
