Clinical Trial Outcome Measures

Primary Measures

  • PD/PK: Dose response of SCH 527123 on ozone-induced sputum neutrophilia in healthy subjects (Part 1) and subjects with COPD (Part 2), measured by placebo-adjusted percent change in sputum neutrophil counts and absolute sputum neutrophil counts.
    • Time Frame: Part 1, four treatment periods, Part 2 three treatment periods duration of the trial.
