Brief Summary

Allergic rhinitis (AR) is a common disease of nasal mucosa, affecting 10% to 40% of the population globally. Allergen specific immunotherapy (AIT) is the only etiological treatment available for AR.Traditionally, AIT is divided into subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT). Artemisia annua is one of the most important allergen that is responsible for seasonal AR in China during July and October. The trial is a randomized, double-blind, placebo-controlled, multicentred, phase III trial. 702 subjects with allergic rhinitis caused by Artemisia pollen were recruited and randomized to the immunotherapy group and placebo group.

Outcome Measures

Primary Outcomes (1)

  • daily combined scores of medication and rhinoconjunctivitis symptoms (CSMRS)

    the daily combined scores of medication and rhinoconjunctivitis symptoms (CSMRS) (ranging from 0 to 6); which was calculated as the combined score of daily average scores of 6 rhinoconjunctivitis symptoms (rhinorrhea, nasal congestion, nasal itching, sneezing, ocular pruritus, and watery eyes) and the daily rescue medication score

    at the peak pollen season(The start was defined as the first of 3 consecutive days with a pollen count of 50 pollen/m3 or greater each day. The end was defined as the last occurrence of 3 consecutive days with ≥50 pollen/m3 each day)

Secondary Outcomes (3)

  • daily total nasal symptom score (dTNSS)

    at the peak pollen season(The start was defined as the first of 3 consecutive days with a pollen count of 50 pollen/m3 or greater each day. The end was defined as the last occurrence of 3 consecutive days with ≥50 pollen/m3 each day)

  • daily Rescue Medication Scores (dRMS)

    at the peak pollen season(The start was defined as the first of 3 consecutive days with a pollen count of 50 pollen/m3 or greater each day. The end was defined as the last occurrence of 3 consecutive days with ≥50 pollen/m3 each day)

  • Adverse events

    From the first day of SLIT to Visit 9(week 32)
