Liver Fibrosis Is Associated With Corrected QT Prolongation During Ledipasvir/Sofosbuvir Treatment for Patients With Chronic Hepatitis C.

ABSTRACT: Combination treatment of ledipasvir and sofosbuvir (LDV/SOF) is first-line treatment for patients with chronic hepatitis C genotype 1 in the United States, Europe, and Japan. However, the influence of LDV/SOF on the cardiovascular system is poorly characterized. A total of 470 chronic hepatitis C patients who started LDV/SOF treatment between September 2015 and February 2016 at nine hospitals in Japan were prospectively enrolled in this study. Corrected QT (QTc) prolongation was defined as a QTc interval ?450 milliseconds. The sustained virologic response rate was 96.0% (451/470), and the discontinuance rate due to adverse effects was 0.9% (4/470). Among 395 patients whose electrocardiogram was evaluated over time and compared with baseline, the QTc interval was significantly prolonged during treatment and returned to baseline levels 12 weeks after the end of treatment. Twenty-four of 376 patients with baseline QTc intervals <450 milliseconds experienced on-treatment QTc prolongation. Higher aspartate aminotransferase-to-platelet ratio index scores (?0.76; odds ratio, 4.375; P = 0.005) and longer QTc intervals (?416 milliseconds; odds ratio, 4.823; P = 0.003) at baseline were significantly associated with on-treatment QTc prolongation on multivariate analysis. Patients with cirrhosis showed significantly longer QTc intervals than those without cirrhosis during treatment but not at baseline, and they developed on-treatment QTc prolongation at a higher rate than patients without cirrhosis. No cardiovascular events occurred, except for 1 patient who developed paroxysmal supraventricular tachycardia. Conclusion: Newly developed QTc prolongation was observed in 6.4% of Japanese patients during treatment and was associated with more advanced fibrosis. (Hepatology Communications 2018; 00:000-000).

Project description:Prevalence of chronic hepatitis C (CH-C) infection in patients of Asian ancestry ranges between 1% and 20%. Interferon (IFN)- and ribavirin (RBV)-containing regimens for CH-C have a negative impact on patient-reported outcomes (PROs) during treatment. The aim of this study was to assess the impact of IFN-free RBV-free sofosbuvir (SOF)-based regimens on PROs in CH-C patients of Asian ancestry. In this observational retrospective study, the PRO data from 12 multicenter multinational phase 3 clinical trials (2012-2015, conducted in Europe, North America, Australia, and New Zealand) of SOF-based regimens with and without IFN, ledipasvir (LDV), and/or RBV were used. At baseline, during treatment, and post-treatment, patients completed 4 validated PRO questionnaires (SF-36, CLDQ-HCV, FACIT-F, and WPAI:SHP). The resulting PROs in Asian patients were compared across the treatment regimens. Of 4485 of the trials' participants, 106 patients were of Asian ancestry (55.7% male, 69.8% treatment-naïve, 17.0% cirrhotic). In comparison with other patients, the Asian CH-C cohort was younger, had lower BMI, and lower rates of pre-treatment psychiatric comorbidities (anxiety, depression, sleep disorders) (all P < .05). At baseline, Asian patients also had lower SF-36 physical functioning scores (on average, by -5.6% on a normalized 0-100% PRO scale, P = .001). During treatment, Asian CH-C patients experienced a decline in their PRO scores while receiving IFN and/or RBV-containing regimens (up to -19.6%, P < .001). In contrast, patients receiving LDV/SOF experienced no PRO decrement and improvement of some PRO scores during treatment (+9.0% in general health of SF-36, P = .03). After achieving SVR-12, some of the PRO scores in Asian patients improved regardless of the regimen (up to +9.3%, P < .001). In multivariate analysis of Asian patients, the use of LDV/SOF was independently associated with higher PRO scores during and soon after the end of treatment (betas +15.0% to +29.3%, all P < .05). Other predictors of PRO impairment included depression, type 2 diabetes mellitus, and cirrhosis. The use of IFN- and RBV-free LDV/SOF regimens leads to PRO improvement in Asian patients with CH-C during treatment. Achieving SVR-12 results in improvement of PRO scores.
