Post Approval Pharmacokinetic Study of Loratadine in Japanese Pediatric and Adult Patients (Study P05539)
March 16, 2017 updated by: Merck Sharp & Dohme LLC
Protocol for Post-approval Commitment Study of Loratadine for PPK Analysis in Japanese Pediatric and Adults Patients
This is a post marketing study to confirm the appropriate dose of loratadine in children by obtaining drug concentration data at multiple time points per child and adult patient, after the patient receives repeated administrations of the approved dose of loratadine.

Description
Inclusion Criteria:
Patients with perennial allergic rhinitis who satisfy all of the following criteria were enrolled in the study:
- Pediatric patients between the ages of 3 and 15 years and adult patients between the ages of 16 and 64 at the time of providing informed consent.
- Outpatients of either sex.
- Pediatric patients for whom written informed consent can be obtained from the guardian before the start of the study. Adult patients from whom written informed consent can be obtained (for patients between the ages of 16 and 19, the guardian must also provide written informed consent).
- Pediatric patients who have the ability to make entries in the patient diary (Record of Drugs and Nasal Symptoms) or entry in the diary is made possible by the guardian. Adult patients who have the ability to make entries in the patient diary.
- Patients for whom treatment with loratadine monotherapy is judged appropriate based on symptoms of allergic rhinitis during the pretreatment observation period.
- Patients confirmed to be allergic to perennial allergen
Exclusion Criteria:
- Patients with a history of epileptic seizures or organic brain disorder in whom there is a possibility that epileptic seizures may be induced
- Patients with a history of hypersensitivity to any component of this drug
- Patients who are pregnant or who may be pregnant, and nursing women
- Patients with severe hepatic, renal, cardiac, or hematological disease or other serious complications and whose general condition is poor
- Patients participating in another clinical study or who have been in a clinical study within the last 30 days.
- Other patients judged inappropriate for study by the investigator or sub-investigator
- Patients allergic to pollen (cedar, mugwort, common ragweed, orchard grass, etc.) and the pollen season is during the period from 7 days before registration to the end of study drug administration
- Patients who developed diseases which might affect nasal symptoms (acute upper respiratory tract infection, acute pharyngo-laryngitis, or acute tonsillitis) in the 7 days before registration
- Patients who received treatment for allergic rhinitis in the 7 days before registration

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean Maximum Plasma Concentration (Cmax) of SCH 29851 (Unchanged Drug; Loratadine), SCH 34117 (Active Metabolite), and SCH 45581 (3OH-SCH 34117)
Time Frame: After 2 and 4 weeks of treatment, and after 1 and 3 weeks of treatment if participant agreed
|
SCH 29851: Two-compartment model used as basic pharmacokinetic (PK) model.
Individual Cmax estimated with basic PPK parameters (apparent total body clearance (CL/F), apparent distribution volumes of central compartment (Vc/F) and peripheral compartment (Vp/F), apparent inter-compartmental clearance (Q/F), absorption rate constant (Ka), lag time, inter- and intra-individual variation) by Bayesian method.
SCH 34117/SCH 45581: One-compartment model used as basic PK model.
Individual Cmax was estimated with PPK parameters (above) on final model by Bayesian method.
|
After 2 and 4 weeks of treatment, and after 1 and 3 weeks of treatment if participant agreed
|
Mean Area Under the Plasma Concentration Time Curve (AUC) of SCH 29851 (Unchanged Drug), SCH 34117 (Active Metabolite), and SCH 45581 (3OH-SCH 34117)
Time Frame: After 2 and 4 weeks of treatment, and after 1 and 3 weeks of treatment if participant agreed
|
SCH 29851: Two-compartment model used as basic pharmacokinetic (PK) model.
Individual AUC estimated with basic PPK parameters (apparent total body clearance (CL/F), apparent distribution volumes of central compartment (Vc/F) and peripheral compartment (Vp/F), apparent inter-compartmental clearance (Q/F), absorption rate constant (Ka), lag time, inter- and intra-individual variation) by Bayesian method.
