Clinical Trial Summary

Allergic rhinitis is an importance disease in Taiwan with its high incidence about 20-30% and gradually increased annually. However, symptom relapse still bothered the majority of patients though there were certain advances in western medicine. In addition, side effects of western medicine, such as lethargy, mouth dryness were noted. Traditional Chinese medicine, especially qi-tonifying regimen has been used and proved benefit to the allergic diseases by many researchers.This study will provide the evidences of gut microbiota changes and immune-modulatory effects of BZYQT for the treatment of allergic rhinitis.

Clinical Trial Description

Recently studies reported that gut microbiota is related to the human immunity modulation of allergic diseases. Investigators are interested to know weather qi-tonifying herbal medicine is through the changes of gut microbiota to modulate human immunity. In this study, a double-blinded, randomized, placebo control design is applied and total 60 perennial allergic rhinitis patients will be enrolled in our study. All subjects will be divided into Bu-Zhong-Yi-Qi-Tang (BZYQT) and placebo control groups, 40 and 20 subjects each. Subjects of BZYQT group will receive capsule of BZYQT, 4gm tid, 12gm a day, while control group will receive similar placebo capsule with same scheme. Total 2 months treatment course will be done. Gut microbiota will be assayed before and after 2 months treatment. Additionally, various parameters for immunologic response will be checked before and after the treatment, including the total IgE amount, the ratio of CD4/CD8 of T lymphocytes, the profile of cytokine such as IL-10 and IL-12 as well as functional change of dendritic cells and T cells. Results will be analyzed statistically including gender analysis. This study will provide the evidences of gut microbiota changes and immune-modulatory effects of BZYQT for the treatment of allergic rhinitis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
