Introduction: Non-interferon-based therapy with direct acting antiviral agents (DAA) have become an integral component of treatment for HCV infection but little is known about their real-world effectiveness. Aim: To evaluate the efficacy and safety of the treatment with DAA-based regimen in HCV patients with advanced fibrosis/cirrhosis in a real life clinical setting. Methods: Retrospective data of patients treated with DAA from January to November 2015 in 7 tertiary referral centers in the Emilia-Romagna Region (Italy) were collected. Patients on the waiting list for orthotopic liver transplantation and with HIV co-infection were excluded. Patients received: sofosbuvir (SOF) [n = 74], SOF + simeprevir (SMV) [n = 149], SOF + daclatasvir (DCV) [n = 69], SOF + ledipasvir [n = 43], SMV + DCV [n = 4], ombitasvir/paritaprevir/ritonavir only [n = 11] or with dasasbuvir [n = 84]. Ribavirin was added at the physician's discretion according to weight. The primary efficacy endpoint was sustained virological response 12 weeks after the last dose of study drug (SVR12). Results: Overall, 435 consecutive patients were treated. The median age was 63 years (range: 29–85); 60% were male, 55.2% were treatment experienced and 81.1% had cirrhosis. The majority (56.6%) had genotype (GT) 1b, 12.4% GT1a, 11.3% GT2, 12.6% GT3 and 7.1% GT4. To date, 347 patients completed treatment and 179 the week 12 of post-treatment follow-up. Three cirrhotics died during treatment and were excluded from analysis. Overall, the SVR12 was 88.8% (159/179). According to GT, the SVR12 was achieved in 17/19 (89.5%) GT1a, in 100/111 (90.1%) GT1b, in 24/26 (92.3%) GT2, in 9/11 (81.8%) GT3 and in 9/12 (75%) GT4. Patients with cirrhosis had a lower response rate than those with advanced fibrosis (86.7% vs 97.2%; p = 0.082). Complete safety data for the entire cohort, updated SVR12 will be presented. Conclusions: The DAA-based regimen was efficacious with low relapse rates in HCV patients in a real-world setting. Patients with cirrhosis seems to respond less well to the different regimens used.

Abstract

Introduction: Non-interferon-based therapy with direct acting antiviral agents (DAA) have become an integral component of treatment for HCV infection but little is known about their real-world effectiveness. Aim: To evaluate the efficacy and safety of the treatment with DAA-based regimen in HCV patients with advanced fibrosis/cirrhosis in a real life clinical setting. Methods: Retrospective data of patients treated with DAA from January to November 2015 in 7 tertiary referral centers in the Emilia-Romagna Region (Italy) were collected. Patients on the waiting list for orthotopic liver transplantation and with HIV co-infection were excluded. Patients received: sofosbuvir (SOF) [n = 74], SOF + simeprevir (SMV) [n = 149], SOF + daclatasvir (DCV) [n = 69], SOF + ledipasvir [n = 43], SMV + DCV [n = 4], ombitasvir/paritaprevir/ritonavir only [n = 11] or with dasasbuvir [n = 84]. Ribavirin was added at the physician's discretion according to weight. The primary efficacy endpoint was sustained virological response 12 weeks after the last dose of study drug (SVR12). Results: Overall, 435 consecutive patients were treated. The median age was 63 years (range: 29–85); 60% were male, 55.2% were treatment experienced and 81.1% had cirrhosis.
