About this study

This is a multi-center, open-labelled study to confirm the safety as main objective, and consisting of minimum 1-week screening period and 2-week treatment period. The subjects who meet the inclusion criteria are to be placed on one of the following two regimens according to their ages at the start of treatment period: once daily administration of levocetirizine at a dose of 1.25 mg (in the morning) to infants aged between 6 months and 1 year old (younger age group), and twice daily administration of levocetirizine at a dose of 1.25 mg (in the morning, in the evening before sleep) to infants aged between 1 year and 2 years old (older age group).

Who can participate

Healthy volunteers accepted: No

  • Pediatric patients who received systemic adrenocorticosteroids within 28 days before Visit 2
  • Pediatric patients who are currently treated or planned to have immunotherapy initiated during the study period
  • Pediatric patients who had abnormal laboratory results that were unrelated to allergic disorders [These patients can be enrolled if the investigator (or sub-investigator) judges that their enrolment poses no clinical problem.]

  • Pediatric patients who suffer from asthma as a complication and require treatment with adrenocorticosteroids (including adrenocorticosteroid combinations)
  • Pediatric patients with the history of convulsion, febrile convulsion or sleep apnea
  • Pediatric patients whose brothers or sisters have history of sleep apnea or sudden infant death syndrome
  • Pediatric patients with history of allergy or hypersensitivity to the ingredients of levocetirizine hydrochloride preparation or piperazine derivatives such as hydroxyzine, cetirizine, cyclizine
  • Pediatric patients with history of drug hypersensitivity
  • Pediatric patients who are considered inappropriate as the subjects of this clinical trial because of liver diseases, renal diseases, heart diseases or other complications that pose clinical problem
  • Pediatric patients whose parents are minors
  • Infants who belong to children's institutions
  • Pediatric patients who participated in other clinical trials for 6 months before enrolment or those who intend to participate in other clinical trials during the clinical trial period.
  • Person meeting any of the following criteria and his/her family (- An employee of GlaxoSmithKline K.K., - Investigator or sub-investigator, - An employee of Site Management Organization (SMO) related with the clinical study)
  • Other pediatric patients who are judged as inappropriate for participating in this clinical trial by the investigator (or sub-investigator)

Treatment and study plan

Levocetirizine

Drug

Clear solution, 0.50 mg levocetirizine dihydrochloride contains in one milliliter of the solution. Levocetirizine oral solution are administered once daily at a dose of 2.5 mL (1.25 mg of levocetirizine) in the morning to infants aged between 6 months and 1 year old

Primary outcomes

  1. Number of Participants With Serious Adverse Events (SAEs) and Non-serious Adverse Events (AEs)

    Time frame: up to Week 2/Early Withdrawal (EW)

    A non-serious AE is defined as any untoward medical occurrence in a participant/clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e., lack of efficacy), abuse, or misuse. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or is a possible drug-induced liver injury. For a list of all SAEs/non-serious AEs occurring at a frequency of >=5%, please see the SAE/non-serious AE module of this record.

Secondary outcomes

  1. Number of Participants With the Indicated Change From the First Day of Treatment in Allergic Rhinitis and Pruritis Associated With Skin Diseases at Weeks 1 and 2/EW, as Assessed by the Investigator/Sub-investigator Based on Legal Representative Impression

    Time frame: First day of treatment; Weeks 1 and 2/Early Withdrawal

    The investigator or sub-investigator made an overall assessment of nasal symptoms (allergic rhinitis [AR]) and pruritus associated with skin diseases (PAWSD) at Weeks 1 and 2 (or at the discontinuation day in the case of early withdrawal [EW] from the clinical trial) by asking the participants' legal representatives to provide feedback using the following scale: 1, significantly improved; 2, moderately improved; 3, mildly improved; 4, no change; 5, mildly worse; 6, moderately worse; 7, significantly worse. Only those participants with AR and PAWSD at Baseline were assessed for improvement in the conditions at Weeks 1 and 2. The "n"s in the category titles reflect the number of participants in the Full Analysis Set (FAS) who had AR and PAWSD at Baseline.

  2. Number of Participants With the Indicated Change From the First Day of Treatment in Nasal Symptoms and Pruritis Associated With Skin Diseases at Weeks 1 and 2/Early Withdrawal, as Assessed by the Investigator or Sub-investigator

    Time frame: First day of treatment; Weeks 1 and 2/Early Withdrawal

    The investigator or sub-investigator comprehensively assessed the participants' improvement in nasal symptoms (allergic rhinitis [AR]) and pruritus associated with skin diseases (PAWSD) at Weeks 1 and 2 (or at the discontinuation day in the case of early withdrawal [EW] from the clinical trial) compared to the first day of treatment by using the following scale: 1, markedly improved; 2, moderately improved; 3, slightly improved; 4, no change; 5, worsened.

  3. Number of Participants Categorized With the Indicated Pruritis Severity on the First Day of Treatment and at Weeks 1 and 2/Early Withdrawal

    Time frame: First day of treatment; Weeks 1 and 2/Early Withdrawal

    The investigator comprehensively assessed the pariticipant's severity of pruritus on the first day of treatment (FDOT), at Week 1, and at Week 2 (or at the discontinuation day in the case of early withdrawal [EW] from the clinical trial) by using the following scale: 4, severe; 3, moderate; 2, mild; 1, slight; 0, none.

  4. Cmax and Cmin of Levocetirizine in Plasma

    Time frame: Weeks 1 and 2/Early Withdrawal

    Cmax is defined as the peak plasma concentration of a drug after administration. Cmin is defined as the lowest (trough) concentration that a drug reaches before the next dose is administered. For both age cohorts, blood samples were collected 1.5-2.5 hours after the last drug administration for assessment of Cmax at either Week 1 or 2/EW. For participants in the >=6 months and <12 months cohort, blood samples were collected 22.5-25.5 hours after the last drug administration for Cmin at a different visit from Cmax sampling. For participants in the >=12 months and <24 months cohort, blood samples were collected 10.5-13.5 hours after the final drug administration for Cmin at a different visit from Cmax sampling. For all participants, if Cmin sampling occurred at Week 1, then Cmax sampling occurred at Week 2/EW, and vice versa.
