Exclusion Criteria: * Any disease that the investigator considers unstable and may affect the patient's safety throughout the study period, or affect or interpretation with the results, or interfere with the patient's ability to complete the entire research process, including but not limited to cardiovascular, gastrointestinal, liver, kidney, neurological, musculoskeletal, infectious, endocrine, metabolic, hematologic diseases, psychiatric disorders, or major limb disorders.

Forced expiratory volume in the first second (FEV1) ≤ 50% of normal estimates, or 2. Acute exacerbation of asthma within 90 days prior to screening, requiring hospitalization (\>24 hours), or 3. used daily doses higher than 1000 mcg of fluticasone or equivalent inhaled corticosteroids (ICS); * The subject had concomitant diseases that prevented him/her from completing the screening period assessment or from evaluating the primary efficacy endpoint; * Subjects with nasal malignancies and benign tumors (e.g., papillomas, hemangiomas, etc.); * Subjects who are unable to use MFNS or who are allergic or intolerant to mometasone furoate nasal spray; * Subjects with a history of anaphylaxis to any biological agent (other than local injection site reactions); * Pregnant or lactating women; * Alcoholism, drug addiction and known drug dependence; * Have participated in clinical trials of other medical devices within 12 weeks before screening; * The subject had poor compliance in the research and could not complete the study as judged by the investigator; * In the judgment of the investigator or sponsoring medical reviewer, it is believed that there are any medical or psychiatric symptoms that put the subject at risk, interfere with participation in the study, or interfere with the interpretation of the results of the study.
