Drug Study in Pediatric Subjects With Migraines (MK0462-083 AM1)

A Randomized, Double-Blind, Placebo-Controlled Study to Assess the Safety, Tolerability, and Single-Dose Pharmacokinetics of MK0462 in Subjects With Migraines Aged 6 to 17 Years

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.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 4 years to 15 years (Child)
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• Panel A and B: Male and female subjects (non-smokers) ages 6 to 17 with a history of migraines
• Panel C: Male subjects (non-smokers) ages 12 to 17 with a history of migraines

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Panel A Rizatriptan; Subjects allocated to Panel A and randomized to receive a single dose of rizatriptan 5 mg orally disintegrating tablet (ODT) on Day 1. Subjects weighing 20-39 kg were allocated to Panel A.	Drug: rizatriptan benzoate (5 mg); A single dose of rizatriptan 5 mg administered on Day 1.; Other Names: MK0462; MAXALT®
Placebo Comparator: Panel A Placebo; Subjects allocated to Panel A and randomized to receive a single dose of rizatriptan 5 mg orally disintegrating tablet (ODT) placebo on Day 1. Subjects weighing 20-39 kg were allocated to Panel A.	Drug: Rizatriptan 5 mg Placebo; A single dose of rizatriptan 5 mg placebo administered on Day 1.
Experimental: Panel B Rizatriptan; Subjects allocated to Panel B and randomized to receive a single dose of rizatriptan 10 mg orally disintegrating tablet (ODT) on Day 1. Subjects weighing 40 kg and above were allocated to Panel B.	Drug: rizatriptan benzoate (10 mg); A single dose of rizatriptan 10 mg administered on Day 1.; Other Names: MK0462; MAXALT®
Placebo Comparator: Panel B Placebo; Subjects allocated to Panel B and randomized to receive a single dose of rizatriptan 10 mg orally disintegrating tablet (ODT) placebo on Day 1. Subjects weighing 40 kg and above were allocated to Panel B.	Drug: Rizatriptan 10 mg Placebo; A single dose of rizatriptan 10 mg placebo administered on Day 1.
Experimental: Panel C Rizatriptan; Subjects allocated to Panel C and randomized to receive a single dose of rizatriptan ODT on Day 1. Subjects in Panel C weighing 20-39 kg received a 5 mg dose and subjects weighing 40 kg and above received a 10 mg dose. Panel C was added to the study by amendment to increase the number of male subjects in the 12-17 year old age group.	Drug: rizatriptan benzoate (5 mg); A single dose of rizatriptan 5 mg administered on Day 1.; Other Names: MK0462; MAXALT®; Drug: rizatriptan benzoate (10 mg); A single dose of rizatriptan 10 mg administered on Day 1.; Other Names: MK0462; MAXALT®
Placebo Comparator: Panel C Placebo; Subjects allocated to Panel C and randomized to receive a single dose of rizatriptan ODT placebo on Day 1. Subjects in Panel C weighing 20-39 kg received a 5 mg placebo dose and subjects weighing 40 kg and above received a 10 mg placebo dose. Panel C was added to the study by amendment to increase the number of male subjects in the 12-17 year old age group.	Drug: Rizatriptan 5 mg Placebo; A single dose of rizatriptan 5 mg placebo administered on Day 1.; Drug: Rizatriptan 10 mg Placebo; A single dose of rizatriptan 10 mg placebo administered on Day 1.
