103 consecutive listed patients without hepatocellular carcinoma were treated with different DAA combinations in 11 European centres between February 2014 and February 2015.
The cumulative incidence of inactivated and delisted patients by competing risk analysis was 15.5% and 0% at 24 weeks, 27.6% and 10.3% at 48 weeks, 33.3% and 19.2% at 60 weeks. The 34 patients who were inactivated showed a median improvement of 3.4 points for MELD (delta MELD, p <0.0001) and 2 points for Child-Pugh (CP) (delta-CP, p <0.0001). Three variables emerged from the most parsimonious multivariate competing risk model as predictors of inactivation for clinical improvement, namely, baseline MELD classes (MELD 16–20: HR = 0.120; p = 0.0005, MELD >20:HR = 0.042; p <0.0001), delta MELD (HR = 1.349; p <0.0001) and delta albumin (HR = 0.307; p = 0.0069) both assessed after 12 weeks of DAA therapy.
This study showed that all oral DAAs were able to reverse liver dysfunction and favoured the inactivation and delisting of about one patient out-of-three and one patient out-of-five in 60 weeks, respectively. Patients with lower MELD scores had higher chances to be delisted. The longer term benefits of therapy need to be ascertained.
The excellent efficacy and safety profile of the new drugs against Hepatitis C virus, “direct acting antivirals” or DAAs, have made antiviral therapy possible also for patients with advanced liver disease and for those on the waiting list for liver transplantation (LT). This study shows for the first time that the DAAs may lead to a remarkable clinical improvement allowing the delisting of one patient out of 5.
