研究概览
简要总结
This study will evaluate the safety and pharmacokinetics of montelukast (MK-0476) in the treatment of Japanese pediatric participants with perennial allergic rhinitis (PAR). The primary hypothesis of this study is that montelukast oral granules (OG) and chewable tablets (CT) provide appropriate exposure to montelukast in Japanese pediatric participants with PAR.

干预措施: Montelukast Oral Granules (OG) (Drug)
Montelukast 5 mg CT/6-9 year olds
Participants receive montelukast 5 mg CT in one tablet PO QD at bed time for 12 weeks
干预措施: Montelukast Chewable Tablets (CT) (Drug)
Montelukast 5 mg CT/10-15 year olds
Participants receive montelukast 5 mg CT in one tablet PO QD at bed time for 12 weeks
干预措施: Montelukast Chewable Tablets (CT) (Drug)
结局指标
主要结局
Time to Cmax (Tmax) of Montelukast CT and Montelukast OG
时间窗: Up to Day 28 after first dose of study drug
Blood samples for PK assessments were collected at either 1 h or 3 h post-dose on Day 1 and at either 14 h or 22 h post-dose on Day 28.
Percentage of Participants Who Experience at Least One Adverse Event (AE)
时间窗: Up to 14 days after last dose of study drug (Up to 14 weeks)
An AE is any unfavorable and unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with the use of study drug or protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening of a pre-existing condition that is temporally associated with the use of study drug is also an AE. Participants were monitored for the occurrence of AEs for up to 14 days after last dose of study drug (up to a total of 14 weeks). AEs were reported based on the dose of study drug participants received.
Percentage of Participants Who Discontinue Study Drug Due to an AE
时间窗: Up to 12 weeks
An AE is any unfavorable and unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with the use of study drug or protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening of a pre-existing condition that is temporally associated with the use of study drug is also an AE. Discontinuations due to an AE were reported based on the dose of study drug participants received.
Area Under the Time-Concentration Curve (AUC 0-∞) of Montelukast CT and Montelukast OG
时间窗: Up to Day 28 after first dose of study drug
Blood samples for pharmacokinetic (PK) assessments were collected at either 1 hour (h) or 3 h post-dose on Day 1 and at either 14 h or 22 h post-dose on Day 28.
Maximum Plasma Concentration (Cmax) of Montelukast CT and Montelukast OG
时间窗: Up to Day 28 after first dose of study drug
Blood samples for PK assessments were collected at either 1 h or 3 h post-dose on Day 1 and at either 14 h or 22 h post-dose on Day 28.
Apparent Elimination Half-life (t1/2) of Montelukast CT and Montelukast OG
时间窗: Up to Day 28 after first dose of study drug
Blood samples for PK assessments were collected at either 1 h or 3 h post-dose on Day 1 and at either 14 h or 22 h post-dose on Day 28.
