Evaluation of the effect of a supratherapeutic dose of intravenous ceftaroline fosamil on the corrected QT interval.

ABSTRACT: A randomized, double-blind, placebo-controlled, 3-period crossover study was conducted in 54 healthy adults to assess the effect of ceftaroline fosamil on the corrected QT (QTc) interval. The QT interval, corrected for heart rate using an individual correction formula (QTcIb), was determined predose and at 1, 1.25, 1.5, 2, 4, 8, 12, and 24.5 h after intravenous dosing with a supratherapeutic dose (1,500 mg) of ceftaroline fosamil, 400 mg moxifloxacin (positive control), and placebo. The pharmacokinetic profile of ceftaroline was also evaluated. At each time point following ceftaroline fosamil administration, the upper limit of the 90% confidence interval (CI) for the placebo-corrected change from predose baseline in QTcIb (ΔΔQTcIb) was below 10 ms (maximum, 3.4 ms at 1.5 h after dosing), i
