简要总结
The study is a single-center, observational design with a 12-month duration. Approximately 100 Chinese adult (18-65 years old) and adolescent (12-17 years old) with moderate to severe house dust mite (HDM) allergic rhinitis (AR) with or without allergic asthma (AA) who are newly prescribed ACARIZAX® will be recruited for evaluation of the relevance of measurement instruments. The instruments referred to three patient-report scales of allergic rhinitis symptom and quality-of-life including the Daily symptom score (DSS), Standardised rhinoconjunctivitis quality-of-life questionnaire [RQLQ(S)], and Visual analogue scale (VAS). Other data will be collected to evaluate the effectiveness and safety of ACARIZAX® under real-world clinical practices.
详细描述
This is a prospective, non-interventional, observational, single-centre, open-label study. Chinese adult (18-65 years old) and adolescent (12-17 years old) HDM AR patients who are newly prescribed with ACARIZAX® at the discretion of attending physician, according to the approved indication by Hainan Provincial Health Commission, will be recruited for this study. Approximately 100 adult (18-65 years old) and adolescent (12-17 years old) patients are expected to be enrolled from Hainan Branch Hospital of Ruijin Hospital. Patients are included in the study only after the decision for treatment with ACARIZAX® has been made, and only with the objective of collecting relevant data about clinical effectiveness and safety of treatment with ACARIZAX® under real-world conditions. No further medical procedures beyond standard care at the discretion of the attending physician are necessary for participation in this study.
Over the 13-month study (including 12-month of treatment), total of 5 scheduled visits will be documented: enrolment and first administration of ACARIZAX® (Visit 1, V0), and subsequent visits performed in 3-month intervals after the first administration at the third month (Visit 2, V1), sixth month (Visit 3, V2), ninth month (Visit 4, V3), and twelfth month (Visit 5, V4) respectively. The actual number and duration of follow-up visits are according to routine practice and may be changed at the physician's discretion. All adverse events (AE) will be collected from the first dose administration until 30 days after the last dose of ACARIZAX® (end of study).

入选标准
- •Adult and adolescent (12-65 years old) allergic rhinitis patients should meet each of the following criteria:
- •Adult with age of 18-65 years for allergic rhinitis with or without allergic asthma. Adolescent with age of 12-17 years for allergic rhinitis.
- •Clinical history and a positive test of dust mite sensitization (positive skin prick test result ≥+++ or positive specific IgE test result ≥grade 3).
- •Persistent moderate to severe dust mite allergic rhinitis despite use of symptom-relieving medication (symptom assessment defined as to assess symptoms of rhinitis by VAS score≥ 5).
- •Newly prescribed with ACARIZAX®.
- •For adults, must provide signed informed consent; for adolescents, written informed consent must be obtained from both guardian and patient himself/herself if the level of intellectual maturity makes it appropriate.
- •Patients with allergic asthma should also meet both of the following criteria:
- •Dust mite induced asthma not well controlled by inhaled corticosteroids and associated with mild to severe dust mite allergic rhinitis.
- •FEV1 ≥ 70% of predicted value after adequate pharmacologic treatment.
排除标准
- •Patients with hypersensitivity to any of the excipients.
- •Patients with severe asthma exacerbations within the last 3 months.
- •Asthmatic patients experiencing an acute respiratory tract infection should have the treatment postponed.
- •Patients with acute severe oral inflammation and oral wounds.
- •Patients who have previous treatment with Omalizumab within the last 120 days.
- •Patient who currently participates in or plan to participate in any interventional clinical study.
- •Any other reason that, in the investigator's opinion, makes the patient unsuitable to participate in this study.
研究组 & 干预措施

结局指标
主要结局
Correlation between three measurement instruments
时间窗: 12 months
• The correlation between the score changes from baseline to 12 months of treatment (Visit 4) of three measurement instruments (as follows). Measurement instruments include: * Daily symptom score (DSS) for 7 consecutive days \[minimum: 0; maximum: 18; Higher score indicates worse symptoms \] * Standardised Rhinoconjunctivitis Quality of Life Questionnaire \[RQLQ(S)\] score, \[minimum: 0; maximum: 168; Higher score indicates worse quality of life\] * Visual Analog Scale (VAS) value of the global discomfort caused by AR. \[minimum: 0mm; maximum: 100mm; Higher score indicates more discomfort caused by AR\]
次要结局
- Change in average of Daily Medication Score (DMS)(12 months)
- Change in average of Total Combined Rhinitis Score (TCRS)(12 months)
- To describe all adverse events (AE) and serious adverse events (SAE)(up to 13 months)
