Information provided by (Responsible Party):
Hoffmann-La Roche
  Purpose
This single-dose, randomized, double-blind, double-dummy, placebo-controlled, positive-controlled four-way crossover study will evaluate the effect of a single dose of danoprevir with low-dose ritonavir on the QC/QTc interval in healthy volunteers. Subjects will be randomly assigned to one of four sequences with treatments of A: therapeutic dose of danoprevir plus ritonavir (DNV/r), B: supratherapeutic dose of DNV/r, C: moxifloxacin and D: placebo, with a washout period of at least 7 days between treatments.

Official Title: A Single-center, Single-dose, Randomized, Double-blind, Double-dummy, Placebo-controlled, Positive-controlled, Four-way Crossover Study to Investigate the Effect of Danoprevir With Low Dose Ritonavir (DNV/r) on the QT/QTc Interval in Healthy Subjects

Primary Outcome Measures:
  • Threshold pharmacological effect on cardiac repolarization as detected by changes in the QT/QTc interval following single dose [ Time Frame: approximately 9 weeks ]

Secondary Outcome Measures:
  • Pharmacokinetics: Plasma concentrations [ Time Frame: approximately 9 weeks ]
  • Safety: Incidence of adverse events [ Time Frame: approximately 9 weeks ]
  • Cardiac response: Electrocardiogram (ECG) [ Time Frame: approximately 9 weeks ]
