Background: As hepatitis C virus (HCV) treatment continues to evolve, there is an ongoing need to understand and optimize real-world disease management. The primary objective of the SIMPLE study was to describe the real-life management of genotype 1 (G1) HCV in Canada treated with boceprevir + pegylated interferon and ribavirin therapy.
Methods: This was an observational, prospective cohort, multicentre, non-interventional study of patients with G1 HCV. A single cohort of adult patients were to be managed as per standard of care (SoC) and treated with 4 weeks of PegRBV dual therapy, followed by boceprevir + PegRBV for 24-44 weeks, with 24-weeks follow-up. Treatment compliance, health care resource utilization (HCRU), HCV viral load, and hematological adverse event (AE) data were collected.
Results: This study enrolled 159 patients. All investigators were well educated on the Canadian consensus guidelines for HCV management but only a minority of patients were treated according to treatment guidelines. Viral response was achieved by >50% of patients by week 8 of therapy and in 50%-60% of tested patients during follow-up. An average of 17.9 HCRU visits were reported during the study period. The most commonly used resources were nursing visits for routine follow-up.
Conclusions: Results from this real-world study suggest that most patients were not treated according to the product monograph. Further studies are required to determine how oral treatments fit into this paradigm and how these findings extrapolate to the current treatment model. This study can serve as a benchmark for future real-world treatment including heath care utilization analyses.
