Design outcomes

Primary

MeasureTime frame
Main Objective: To establish the dose-response relation of Org 25969 given as a reversal agent of rocuronium or vecuronium at 1-2 PTCs for Caucasian subjects.;Primary end point(s): Time from start administration of Org 25969 to recovery T4/T1 ratio to 0.9.;Secondary Objective: • To show equivalence of recovery of the T4/T1 ratio to 0.9 after reversal with Org 25969 administered at 1-2 PTCs between Japanese and Caucasian subjects, for both rocuronium and vecuronium. • To compare the safety of single doses of Org 25969 administered in subjects of ASA 1 – 3 between Japanese and Caucasian subjects, for both rocuronium and vecuronium.
