Eight-Week Outcomes of Ledipasvir/Sofosbuvir in Noncirrhotic Treatment-Naive Patients with Hepatitis C: Analysis of Pharmacy-Based Data.

Abstract

Clinical trials have demonstrated that 8 weeks of ledipasvir and sofosbuvir (LDV/SOF) achieved high rates of sustained virologic response at 12 weeks (SVR12) in patients with hepatitis C viral (HCV) genotype 1 infection. The effectiveness of this combination was noted to be robust in treatment-naive noncirrhotic patients and in patients with an HCV viral load of < 6 million IU/mL before treatment. Generalizability of these results to community clinical practice, however, was advised with caution due to the variability of staging methods, fluctuating nature of viral loads, lack of prospective trials, and real-life confirmation. To evaluate the efficacy, defined as SVR12, of LDV/SOF in a real-world setting. Patients met inclusion criteria if given 8 weeks of LDV/SOF by a specialty pharmacy from October 2014 to October 2015 and if SVR12 was assessed after therapy completion. Clinical outcomes data were obtained from the pharmacy database. Of the 6,391 prescriptions of LDV/SOF received by the pharmacy, 3,648 (57%) were covered by insurance, and among them, only 511 (14%) were for an 8-week regimen. SVR12 data were available for 380 (74%) patients who completed an 8-week regimen. 230 different prescribers wrote prescriptions, and 57 different insurance plans approved the 8-week regimen. The majority (74%) of patients were followed by gastroenterology clinics. The 380 patients included in the analysis were all treatment-naive HCV genotype 1 patients. Overall, SVR12 was achieved in 97% of patients, while 10 patients relapsed. The SVR12 rates were lower (93%) in patients with stage 3 fibrosis, particularly in African Americans (29 of 35: 83%). Outcomes were favorable for the 8-week use of LDV/SOF in a noncontrolled real-world setting in treatment-naive noncirrhotic patients with a baseline viral load < 6 million IU/mL. Use of this approach in African Americans with evidence of advanced fibrosis should be avoided. No outside funding supported this study. Lott is an employee of Diplomat Pharmacy.
