Efficacy of DAAs in the Treatment of Chronic HCV: Real-World Data from the Private Health-Care Sector of the Kingdom of Saudi Arabia.

BACKGROUND AND AIM: The hepatitis C virus (HCV) is considered a global health challenge that requires urgent interventions for prevention and control. In this study, we aimed to evaluate the effectiveness of direct-acting antiviral agents (DAAs) for HCV-infected patients in the Kingdom of Saudi Arabia (KSA). PATIENTS AND METHODS: In this retrospective cohort study, we ascertained data of patients treated with DAA-based regimens for chronic HCV in the private health-care sector hospitals of KSA between April 2015 and December 2017. Data regarding presence or absence of liver cirrhosis, virus genotype, quantitative HCV RNA test, fibrosis stage, and history of liver disease were included. The primary end point of the study was the overall cure rate, defined as the number of patients achieving sustained viral response (SVR) rate at least 12 weeks following completion of treatment, divided by the total number of patients included in the study. RESULTS: A total of 262 patients fulfilled the study inclusion criteria. Adult patients were enrolled, of which 114 (44%) were females and 148 (56%) were males. About 105 of the patients (40%) were cirrhotic and 156 were treatment-naïve patients (60%), 84 patients were interferon (INF) experienced, and 22 patients had previously received new DAAs but failed to achieve SVR. The majority of patients received ledipasvir-sofosbuvir±RBV (57%) with SVR rate of approximately 97%. CONCLUSIONS: Our local real-world data indicate an overall HCV cure rate of 97% following treatment with DDA#x2019;s when prescribed in the private sector. This estimate is acquiescence with previously reported global cure rates.

The Impact of the Pharmaceutical Care Management Model of Hepatitis C Medications on the Cost at Health Insurance Level.

OBJECTIVE: The aim of this study is to evaluate the impact of adopting a pharmaceutical care model on clinical outcomes, patient satisfaction, and cost at a health payer level. METHODS: All patients with hepatitis C virus (HCV) who were insured by Bupa Arabia, with a direct-acting antivirals prior authorization drug request between April 2015 and October 2018 were included in this retrospective quasi-experimental study. The clinical outcome was the achievement of a sustained virologic response at least 12 weeks from end of treatment. Economic and patients' satisfaction outcomes were included in this study. The differences in cost of treatment was analyzed by using the paired t test. Stata statistical software package (StataCorp, College Station, TX) was used for data analysis. RESULTS: A total of 371 patients were enrolled in this program of which 74% (n = 273) required clinical intervention. Among those, HCV treatment was modified for 64%. The overall cure rate was 97% among 267 patients for which sustained virologic responses were available. The results of the paired t test show that there was a 38% reduction in the mean direct cost of medications before and after intervention (95% confidence interval, 33%-43%; P<.001) and the calculated patients' satisfaction was 98%. CONCLUSIONS: A structured pharmaceutical care program for HCV patients can guide the use of specialty medications to achieve optimal clinical outcomes, with lower expenditures and high patients' satisfaction. We can conclude that healthcare insurance can play a key role in managing specialty pharmaceuticals like HCV medications. Because this is a preliminary study, further studies are needed in an experimental design to strengthen the evidence behind the effectiveness of such a program.
