Abstract
Objective: NVA237 (glycopyrronium bromide) is a once-daily long-acting muscarinic antagonist (LAMA) in development for the treatment of chronic obstructive pulmonary disease (COPD). This study investigated the pharmacokinetics (PK) of NVA237 following single and repeated once-daily inhalation in mild to moderate COPD patients.
Methods: In this double-blind, parallel-group study, COPD patients were randomised to a 14-day treatment with NVA237 (25, 50, 100 or 200 μg) or placebo. Plasma concentration-time profiles and urinary excretion of NVA237 were determined on Days 1 and 14.
Results: The median time to reach maximal plasma concentration (tmax) was 5 or 6.5 min post-inhalation. At steady state (Day 14), total and maximum systemic exposure (AUC0-24, Cmax) to NVA237 and urinary excretion of unchanged drug (Ae0-24) was approximately dose proportional over the 50 to 200 µg dose range. The average exposure was 1.4- to 1.7-fold higher on Day 14 compared with Day 1. The mean terminal elimination half-life (t½) of NVA237 ranged between 13 and 22 h. Steady-state plasma concentrations were reached within one week of treatment. Renal clearance (CLR) was similar across doses both after single and repeated dosing, ranging between 17.4 and 20.6 L/h. Urinary excretion of NVA237 enantiomers ([3S,2R]- and [3R,2S]-stereoisomers) was similar with respect to the amount excreted within 24 h and the excretion rate.
Conclusions: The pharmacokinetics of NVA237 were consistent between doses with limited systemic accumulation at steady state after repeated once-daily inhalation
