BACKGROUND AND OBJECTIVE Chronic hepatitis C virus (HCV) infection is a major cause of liver transplantation. Drug-drug interactions (DDIs) with cyclosporine and tacrolimus hindered the use of first-generation protease inhibitors in transplant recipients. The current study investigated DDIs between daclatasvir-a pan-genotypic HCV NS5A inhibitor with(More)
The objective was to characterise apixaban pharmacodynamic (PD) activity in umbilical cord (UC), paediatric, and adult plasma. Plasma was obtained from blood samples from six UC donors, 70 paediatric (neonates [birth-≤1 month], infants [>1-≤6 months], toddlers [>6 months-≤2 years], young children [>2-≤6 years], children [>6-≤12 years], adolescents [>12-≤18(More)
AIMS This open label study was conducted to assess the effect of renal impairment (RI) on the pharmacokinetics (PK) of peginterferon lambda-1a (Lambda). METHODS Subjects (age 18-75 years, BMI 18-35 kg m(-2) ) were enrolled into one of five renal function groups: normal (n = 12), mild RI (n = 8), moderate RI (n = 8), severe RI (n = 7), end-stage renal(More)
BMS-986142 is an oral, small-molecule reversible inhibitor of Bruton’s tyrosine kinase. The main objectives of our phase I studies were to characterize the safety and tolerability, pharmacokinetics, and pharmacodynamics of BMS-986142 in healthy participants, and to investigate the potential for the effect of BMS-986142 on the PK of methotrexate (MTX) in(More)
Tissue samples taken during a surgical procedure performed for therapeutic reasons in 27 patients with acquired valvular heart disease (a.v.h.d.) were subjected to histopathological examinations. The aim of the work was to carry out simultaneous studies of several organs in the same patients. The samples were taken from: left heart auricle (15 cases), heart(More)
