  Purpose

A study to assess the safety, tolerability, and single dose pharmacokinetics of a marketed drug in pediatric subjects with migraines.

After completion of a portion of the study (Panels A and B), a regulatory agency issued an amended request that the 12-17 year old age group studied should include a similar number of male and female subjects. Therefore, the study was amended to add an additional panel of subjects (Panel C) to ensure gender balance specifically in this age group.

Primary Outcome Measures:
  • Safety and Tolerability of Single Doses of Rizatriptan in Pediatric Migraineurs [ Time Frame: 24 Hours ] [ Designated as safety issue: Yes ]
    All adverse experiences spontaneously reported by subject and/or observed by investigator and repeated clinical evaluation of physical examinations, vital signs, 12-lead ECG (electrocardiogram) and laboratory safety tests (hematology/blood chemistry/urinalysis)


Secondary Outcome Measures:
  • Preliminary Pharmacokinetic Data Following Single Dose Administration of Rizatriptan- Area Under the Curve (AUC(0-∞)) [ Time Frame: 24 Hours ] [ Designated as safety issue: No ]
    Preliminary pharmacokinetics data; Area Under the Curve (AUC(0-∞)); i.e., area under the concentration-time plot

  • Preliminary Pharmacokinetic Data Following Single Dose Administration of Rizatriptan - Maximum Concentration (Cmax) [ Time Frame: 24 Hours ] [ Designated as safety issue: No ]
    Preliminary pharmacokinetics data; Maximum concentration (Cmax); i.e, highest concentration of drug achieved

  • Preliminary Pharmacokinetic Data Following Single Dose Administration of Rizatriptan - Time to Maximum Concentration (Tmax) [ Time Frame: 24 Hours ] [ Designated as safety issue: No ]
    Preliminary pharmacokinetics data; Time to maximum concentration (Tmax); i.e., amount of time required to reach maximum concentration

  • Preliminary Pharmacokinetic Data Following Single Dose Administration of Rizatriptan - Apparent Half-life (Apparent t½) [ Time Frame: 24 Hours ] [ Designated as safety issue: No ]
    Preliminary pharmacokinetics data; Apparent half-life (t½)
