Brief Summary:
The purpose of this study is to evaluate the efficacy and safety of probiotics eN-Lac® capsules (Lactobacillus paracasei GMNL-32) for the treatment of children with perennial allergic rhinitis(PAR).

Condition or disease Intervention/treatment Phase
Perennial Allergic Rhinitis Probiotics Lactobacillus Paracasei GMNL-32 (eN-Lac®) Biological: eN-Lac® Other: Placebo Phase 3

Detailed Description:
This study is PhaseIII clinical trial. According the results of PhaseII study,we find out the optimal dose and its maximum effectiveness in relieving the nasal symptoms of eN-Lac® (Lactobacillus paracasei GMNL-32) in children with PAR.

Study Type : Interventional  (Clinical Trial)

Arm Intervention/treatment
Experimental: eN-Lac® Capsules Biological: eN-Lac®
One capsule with 2x10^9 colony forming unit (cfu) LP GMNL-32, once daily, po
Other Name: eN-Lac® Capsules (Lactobacillus paracasei GMNL-32)

Placebo Capsules Other: Placebo
One placebo capsule, once daily, po
Other Name: Placebo Capsules

Primary Outcome Measures :
  1. Evaluate the efficacy profile of probiotics Lactobacillus paracasei GMNL-32 (eN-Lac®) in children with perennial allergic rhinitis. [ Time Frame: NTSS is recorded daily on subject's DRC (daily record card) at the 8th week from baseline. ]
    NTSS is determined by the severity of allergic symptoms, including sneezing, rhinorrhea, nasal itching, and nasal stuffiness. These symptoms are evaluated using a four-point scale, namely, 0 = Absent, 1 = Mild (present but not disturbing), 2 = Moderate (disturbing but not hampering daytime activities and/or sleep), 3 = Severe (hampering daytime activities and/or sleep). NTSS is calculated by the sum of the scores of the symptoms.

Secondary Outcome Measures :
  1. The safety features are evaluated through the changes of vital signs, physical examinations, laboratory test result (hematology, biochemistry and urinalysis tests), as well as the occurrence of adverse event. [ Time Frame: at 8th week from basline ]
    The incidence of adverse events will be categorized by severity and related to the time of occurrence. Changes in physical examinations, changes in laboratory test results (hematology, biochemistry and urinalysis tests) from screening period, and change of vital signs will be summarized and analyzed by the descriptive statistics.

Exclusion Criteria

  • Subjects have clinically significant laboratory abnormality results (hematology, biochemistry or urinalysis tests) as determined by the investigator (tests performed during 14 days prior to visit 1 or during baseline period can be used for evaluating those criteria).

  • Subjects are undergoing desensitization therapy within 3 months prior to the screening period or subjects with vasomotor rhinitis.
  • Subjects have participated investigational drug trial within 4 weeks before entering this study.
  • Subjects are pregnant, lactating or planning to become pregnant.
  • Subjects with any other serious diseases considered by the investigator that could interfere with the performance of NTSS result.
  • Women of childbearing potential who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period.
