What researchers measure

Primary outcomes

  1. To evaluate the safety and tolerability of single oral doses of MK0633 in pediatric asthma patients.

    Time frame: Physical examinations, vital sign measurements, laboratory safety tests (blood chemistry, hematology and urinalysis), urine ß-hCG test, and 12-lead ECGs will be performed at various scheduled time points throughout the study.

Secondary outcomes

  1. To obtain information on plasma pharmacokinetics (e.g., AUC0-inf, Cmax, Tmax, apparent t½,) of MK0633 after a single oral dose administration in pediatric asthma patients

    Time frame: Plasma will be analyzed at specific time-points for MK0633 concentrations. Urine will be collected for the measurement of LTE4 concentration.
