Overview
Brief Summary
The conduct of this clinical trial is aimed at determining the most suitable dose regimen for children in different age groups, and secondarily to assess the safety and tolerability of bilastine in this paediatric population subset.
Detailed Description
The objective of this study is to assess the pharmacokinetics of bilastine in children (aged 2 to \<12 years) with allergic rhinoconjunctivitis (seasonal allergic rhinitis \[SAR\] and/or perennial allergic rhinitis \[PAR\]) or chronic urticaria (CU) in order to ascertain that the systemic exposure attained with a dose of 10 mg/QD or lower is comparable to that achieved in adults and adolescents administered with a dose of 20 mg/QD. Additional objectives are to describe the safety and tolerability of a repeated administration of bilastine in children with AR or CU.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Either sex aged from ≥ 2 to \< 12 years of age. Female subjects must not be of child bearing potential.
- •Height and weight within a majority range (e.g., 25th through 75th percentile) of the subject's age and sex as provided in national tables.
- •Documented history of SAR/PAR or CU at the time of inclusion. Subjects must be symptomatic at screening as judged by the investigator.
- •A documented positive skin prick test or IgE test (RAST) for at least one seasonal or perennial allergen in children with AR obtained within the 12 months prior to inclusion.
- •Excepting AR or CU, judged to be in general good health based on medical history, physical examination and clinical laboratory tests, with a QTc duration on the ECG recorded at screening within the normal range (≤ 440 msec).
- •Written informed consent signed by the legal representative of the minor (his/her parent(s) or a person legally appointed if different from parent(s)) and, where applicable, assent signed by the child, according to local regulations.
Exclusion Criteria
- •Female subjects of childbearing potential. If menarche occurs after study enrolment and during the dosing period, the subject should be discontinued from the treatment and followed up for safety as per protocol. Occurrence of menarche in the course of the study should always be documented.
- •Intake of another investigational medication in another clinical study within 30 days prior to the first study drug intake.
- •Clinically significant ECG abnormalities as judged by the investigator (e.g., Wolff-Parkinson-White \[WPW\] syndrome, long QT syndrome).
- •Known allergy/hypersensitivity to the study drug or its inactive ingredients.
- •Any clinical conditions or circumstances that in the opinion of the investigator would make the subject unsuitable for the study (e.g., hepatic impairment, renal impairment, mental impairment, cardiac disease).
- •Subjects with known positive Hepatitis B surface antigen (Hbs Ag), or Hepatitis C antibody or who are known to be human immunodeficiency virus (HIV) positive. No testing will be required for this study.
- •Subjects who are expected to take during the study period or have taken any of the following medications prior to inclusion in the study and have not complied with the specified wash out period of 7 days unless otherwise noted:
- •Oral corticosteroids.
- •Oral antihistamines: loratadine, desloratadine, and fexofenadine.
- •Anti-leukotrienes
Arms & Interventions
10 mg Bilastine once daily for 7 days
10 mg Bilastine dispersible oral tablet
Intervention: Bilastine
Outcomes
Primary Outcomes
The primary objective is to assess the pharmacokinetics of bilastine in children (aged 2 to <12 years) with allergic rhinoconjunctivitis (seasonal allergic rhinitis and/or perennial allergic rhinitis [SAR/PAR]) or chronic urticaria (CU)
Time Frame: 1 day (visit 3, Day 7)
Determination of plasma concentrations versus time (between 1 and 6 samples per subject at various time intervals after dosing according to an optimised sampling protocol) in order to perform a population pharmacokinetic analysis. For Group A, samples of venous blood will be just prior to dose administration, and at 0.25, 0.5, 0.8, 1.0, 1.2, 1.5, 3.0, 4.0, 6.0, 8.0, 10.0, 12.0, and 24.0 hours after dose administration. For Group B samples of venous blood will be just prior to dose administration, and at 0.25, 0.5, 1.0, 1.5, 3.0, 6.0, 8.0, 10.0, and 12.0 hours after dose administration.
Secondary Outcomes
- The secondary objectives are to describe the safety and tolerability of a repeated administration of bilastine in the aforementioned paediatric subset with allergic rhinoconjunctivitis (SAR/PAR) or chronic urticaria (CU).(5 weeks)
