Response of Daclatasvir and Sofosbuvir in Treatment-Naïve, HCV Genotype 3, Non-Cirrhotic Pakistani Population: 1 Year Follow-Up Experience

Abstract

using daclatasvir and sofosbuvir in treatment-naive, non-cirrhotic HCV genotype 3 Pakistani population. Methodology: From January 2017 to February 2019, HCV patients who met the inclusion criteria were included in this open-label, non-randomized, uncontrolled observational trial at HBS General Hospital in Islamabad. A 12-week course of oral daclatasvir and sofosbuvir therapy was administered to each participant. Each patient got 400mg of sofosbuvir and 60mg of daclatasvir. Treatment outcomes included sustained virological response (SVR12 and SVR24), rapid virological response (RVR), and end-of-treatment response (ETR) as primary and secondary respectively. Results: There were 105 participants in the study, of which 72.3% were male and 27.6% were female. RVR for male was 92% (p=0.002), while it was 89.65% for female (p=0.004). 96.05% of the male and 93.1% of the female achieved ETR (p=0.002). Both 93.1% of female and 93.4% of male had SVR12 (p=0.001). A single male patient experienced relapse after achieving SVR12 (p=060). SVR24 rates for male and female were 92.1% (p=0.003) and 93.1%, (p=0.003) respectively. The combination therapy was well-tolerated, with the primary side effect being fatigue (36% in males, 44% in females). Conclusion: The combination therapy of daclatasvir and sofosbuvir demonstrated both safety and efficacy in treating treatment-naïve, non-cirrhotic individuals with HCV genotype 3 in Pakistan. The study underscores the potential of direct-acting antiviral agents in addressing the challenge of HCV infections.
