Abstract
INTRODUCTION AND AIMS
Treatment of hepatitis C virus (HCV) genotype 4 patient with fixed dose combination of ombitasvir-paritaprevir-ritonavir plus ribavirin (OBV/rPTV/RBV) has been proven efficacy and safety in many clinical trials. The current study reports the efficacy and safety of OBV/rPTV/RBV (for treatment-naïve), and OBV/rPTV/RBV/sofosbuvir (SOF) (for treatment-experienced), in chronic HCV genotype 4 patients in real life settings.
METHODS
Prospective cohort study including all adult chronic HCV genotype 4 patients who were scheduled to receive OBV/rPTV/RBV ± SOF for 12 or 24 weeks in New Cairo Viral Hepatitis Treatment Center. The primary efficacy endpoint was a virologic response at posttreatment week 12 (SVR12). Changes in hematological parameters, liver biochemical profile and fibrosis-4 index (FIB-4), as well as clinical and laboratory adverse events (AEs) across follow up visits (week 4, end of treatment [EOT], and SVR12), were recorded.
RESULTS
Our study included 325 patients (age; 47.63 ± 12.63 years, 55.38% [n = 180] men). Most of the included patients (89.85%, n = 292) were treatment naïve and only 7% (n = 23) had liver cirrhosis. Overall, SVR12 was attained by 98.44% (316 of 321) of the patients; 97.15% (307 of 316) of patients who received 12 weeks of OBV/rPTV/RBV ± SOF and 100% (9 of 9) of patients who received 24 weeks of OBV/rPTV/RBV as assessed by modified intention to treat analysis. There was a significant improvement of baseline alanine aminotransferase, aspartate aminotransferase, hemoglobin, FIB-4 at SVR12 (P < 0.05). The most common reported AEs were anemia (n = 106), fatigue (n = 41) and elevated indirect bilirubin (n = 37).
CONCLUSION
OBV/rPTV/RBV (±SOF) is a highly effective therapy for chronic HCV patients in real life settings.
