OBJECTIVE Glycopyrronium (NVA237), a once-daily long-acting muscarinic antagonist, has recently been approved for the treatment of patients with chronic obstructive pulmonary disease (COPD). This study evaluated the effect of glycopyrronium on the QT interval and other cardiac parameters in healthy subjects. METHODS This randomized, partially blinded,(More)
OBJECTIVES QVA149 is a dual bronchodilator, containing a fixed-dose combination of the long-acting β2-agonist indacaterol and long-acting muscarinic antagonist glycopyrronium, for the treatment of chronic obstructive pulmonary disease (COPD). Here we assess the potential of QVA149 (440/200 μg) at 4-fold the therapeutic dose for causing cardiac(More)
The constitutive androstane receptor (CAR) and the pregnane X receptor (PXR) are closely related nuclear receptors involved in drug metabolism and play important roles in the mechanism of phenobarbital (PB)-induced rodent nongenotoxic hepatocarcinogenesis. Here, we have used a humanized CAR/PXR mouse model to examine potential species differences in(More)
The A8 Global Harmonization Team focused on the documentation needed to support both small and large molecule bioanalysis. Current regulatory requirements were compiled and compared. The scope of the team’s discussions included the validation report, the bioanalytical report, study plans, raw data, and bioanalytical summaries for the common technical(More)
A sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the determination of valsartan in human plasma was developed and validated. A 0.5 ml aliquot was extracted using solid-phase extraction in an Empore high performance extraction disk plate, universal resin 96-well format. The estimated calibration range of the method was 2-2000(More)
TCH346 (dibenzo[b,f]oxepin-10-ylmethyl-prop-2-ynylamine) is a novel propargylamine compound under investigation as a putative agent in the treatment of chronic neurodegenerative illnesses. To support clinical studies an analytical method was developed for TCH346 plus its three amine metabolites and a carboxylic acid metabolite in human plasma. Using a(More)
OBJECTIVES This study aimed to evaluate influence of ethnic factors on the pharmacokinetics of orally inhaled QMF149, a novel combination of an approved longacting β2-agonist, indacaterol (Onbrez® Breezhaler® for COPD), and an approved inhaled corticosteroid, mometasone furoate (MF), (Asmanex® Twisthaler® for asthma), following multiple dose administration(More)
Glycopyrronium is a once-daily long-acting muscarinic antagonist for the maintenance treatment of patients with chronic obstructive pulmonary disease. This study assessed the pharmacokinetics of inhaled glycopyrronium 50 µg once-daily for 14 days in healthy Chinese subjects. In this open-label study, 12 Chinese healthy subjects (six males and six females;(More)
RATIONALE To assess ethnic sensitivity of indacaterol systemic pharmacokinetics in Japanese vs. non-Japanese patients. METHODS Analyses were in three parts: data from a single "all Asian" clinical study; and two on pooled data - one using a linear mixed effects (LME) model and the other a non-linear mixed effects (NLME) model. The NLME model analyzed(More)
PURPOSE QMF149 is a fixed-dose combination of the long-acting β2 agonist, indacaterol and the corticosteroid, mometasone furoate that is currently under development for treatment of patients with asthma and chronic obstructive pulmonary disease. We describe here a study designed to assess any pharmacokinetic (PK) and/or biopharmaceutical interaction between(More)
