Background/aims: Ledipasvir/sofosbuvir (LDV/SOF) combination is administered for 12 to 24 weeks to treat hepatitis C virus (HCV); guidelines recommend 8 weeks treatment duration for HCV genotype (GT) 1 infection based on the patient's baseline characteristics. Data on treating HCV GT4 with LDV/SOF are limited. In this prospective cohort study, the efficacy and safety of 8 weeks treatment duration with LDV/SOF was evaluated in HCV GT4 patients in Saudi Arabia.

Patients And Methods: Treatment-naïve, non-cirrhotic HCV GT4 patients received LDV/SOF for 8 weeks. HCV RNA levels and laboratory evaluations were recorded at baseline and at Weeks 4, 8, and 20. The primary endpoint was sustained virologic response 12 weeks after the end of the treatment (SVR12). Safety data were also recorded.

Results: Forty-five patients with a mean age of 43.9 ± 17.2 years participated, of whom 57.8% were male. Mean logHCV RNA was 6.26 ± 6.32 IU/mL and most (91.1%) had baseline HCV RNA levels <6 million IU/mL. The most frequent comorbidities were hypertension and diabetes mellitus (20.0% each). Concomitant medication was taken by 18 patients (40.0%), of whom two took proton pump inhibitors. Overall, SVR12 was 97.8% (95% confidence interval [CI]: 88.2%-99.9%); one patient (2.2%) relapsed post treatment. No serious adverse events or discontinuations were reported. Eighteen patients (44.4%) had 38 adverse events related to LDV/SOF; the most frequent was headache.

Conclusions: An 8-week regimen of LDV/SOF was well tolerated and efficacious in this treatment-naïve, non-cirrhotic HCV GT4-infected population. This study provides valuable information on a short treatment regimen for HCV GT4 infection in a real-world setting.

Real life efficacy of ledipasvir/sofosbuvir in hepatitis C genotype 4-infected patients with advanced liver fibrosis and decompensated cirrhosis.

Limited clinical trial data has shown high efficacy of co-formulated ledipasvir/sofosbuvir (LDV/SOF) in the treatment of hepatitis C virus (HCV) genotype (GT)-4 infected cirrhotic patients. We assessed real-world safety and efficacy of LDV/SOF with or without ribavirin (RBV) in GT4-infected patients with compensated and decompensated cirrhosis.

Patients & Methods: This observational cohort (n = 213) included GT4 treatment-naïve (59.6%) and -experienced (40.4%) patients with advanced fibrosis (F3, Metavir; n = 30), compensated (F4, n = 135) and decompensated cirrhosis (n = 48) treated for 12 (n = 202) or 24 weeks (n = 11) with LDV/SOF. RBV was dosed by physician discretion between 600-1200 mg daily. Patients with prior DAA failure were excluded from the analysis. The primary efficacy endpoint was sustained virologic response 12 weeks after treatment (SVR12) on an intention-to-treat analysis, and occurrence of serious adverse events (SAEs).

Results: The mean age of the overall cohort was 59.6 ± 12.1 years and 125 (58.7) were female. Overall, 197 (92.5%) of the patients achieved SVR12, including 93.3% of F3 fibrosis, 93.3% of compensated cirrhotics and 89.6% of the decompensated cirrhotics (P = 0.686). Addition of RBV (68.5%) did not enhance efficacy (91.8% vs. 94.0% without RBV, P = 0.563), including in F3 fibrosis, compensated and decompensated cirrhosis (P > 0.05, for all). There was no difference in SVR12 rates with 24 and 12 weeks therapy (90.9% and 92.6%, respectively; P = 0.586). Treatment failure (n = 16) was mostly related to relapse (n = 11), while on-treatment death (n = 3) and breakthrough (n = 2) comprised a minority. SAEs occurred in 9 (4.2%) patients requiring early treatment discontinuation in 4 (3 on-treatment deaths and 1 pregnancy).

Conclusion: LDV/SOF therapy yielded high SVR12 rates in both compensated and decompensated cirrhotic GT4 patients. The addition of RBV to this regimen did not improve efficacy. The safety profile of this regimen was comparable with that reported for other HCV genotypes.

Efficacy and Safety of Simeprevir or Daclatasvir in Combination With Sofosbuvir for the Treatment of Hepatitis C Genotype 4 Infection.

J Clin Gastroenterol 2018 May/Jun;52(5):452-457

Department of Gastroenterology, Hepatology & Endoscopy, Prince Sultan Military Medical City.

Introduction: The combination of sofosbuvir (SOF) with simeprevir (SMV) or daclatasvir (DCV) is very effective in treating hepatitis C virus (HCV) infection, particularly genotype (GT) 1. However, the data on GT4 are very limited. We aimed to determine the efficacy and safety of SOF in combination with either SMV or DCV in GT4-infected patients.

Patients And Methods: In this real life, prospective, observational study, HCV (GT4) patients (n=96) were evaluated in 2 groups on the basis of the 12-week treatment regimen they received. Group 1 (n=56) patients were treated with SOF and SMV±ribavirin (RBV), whereas group 2 patients were treated with SOF and DCV±RBV (n=40). The primary efficacy endpoint was sustained virologic response 12, whereas the primary safety endpoint was drug discontinuation or occurrence of grade 3/4 adverse events.

Results: The mean age was 49±14.6 years (59.4% men). Cirrhosis was present in 53.6% and 35.0% of groups 1 and 2, respectively, whereas 27 patients (48.2%) in group 1 and 21 patients (52.5%) in group 2 had failed prior interferon-based treatment. The median pretreatment HCV-RNA log10 was 6.1 (3.6 to 7.0) and 6.0 (3.6 to 7.2) IU/mL in groups 1 and 2, respectively. RBV was given to 17 patients (30.4%) in group 1 and 2 patients (5%) in group 2. All patients achieved sustained virologic response 12 (100%). Adverse events occurred in 32% of patients (grade 1 and 2), but none discontinued treatment. One patient died in the SMV group (not related to treatment).

Conclusions: SMV/SOF or DCV/SOF combinations are safe and highly effective in HCV-GT4 treatment. Cirrhosis and failure of prior interferon-based treatment did not influence treatment response.
