Phase II Study of JT002 in the Treatment of Seasonal Allergic Rhinitis in Adults

Exclusion Criteria

• •1. Pregnant or lactating women.
• •2. History of excessive smoking, alcoholism or Drug of Abuse within 6 months prior to screening. Alcoholism is defined as alcohol consumption of more than 14 units per week (1 unit of alcohol ≈ 360 mL of beer or 45 mL of spirits with 40% alcohol content or 150 mL of wine); excessive smoking is defined as current average daily smoking of more than 10 cigarettes.
• •3. In the opinion of the investigator, any other situation that may interfere with the participant's compliance and completion of the protocol, or affect the efficacy and safety evaluation of the study drug.
• •4. Prior use of JT002 or a history of drug allergy to any study drug component is known. Drug allergy or hypersensitivity to immunosuppression/immunomodulators at screening will result in an unacceptable risk to participants if they participate in this study.
• •5. Patients with rhinitis who have previously demonstrated an inability to tolerate nasal drops.
• •6. Patients with perennial allergic rhinitis, unless the investigator evaluates that the patient's current symptoms and signs are caused by obvious exacerbation of seasonal allergic rhinitis.
• •7. Nasal disorders that may affect drug absorption are found on nasal examination on screening day, such as nasal mucosal erosion, nasal mucosal ulcer, sinusitis, rhinitis.
• •8. Medicamentosa, nasal polyps or abnormal nasal cavity structure, nasal trauma (such as nasal puncture), or septal deviation or nasal septum perforation.
• •9. Patients who have received nasal operation within 3 months prior to screening or have incompletely healed nasal trauma.
• •10. Active respiratory tract infection (including but not limited to Bronchitis, pneumonia or influenza, upper respiratory tract infection or Sinus infection) within 14 days prior to screening, or patients who may develop upper respiratory tract infection during the treatment run-in period. Occasional acute asthma or patients with mild exercise-induced asthma are acceptable, provided that the treatment is limited to inhaled short-acting β-agonists (maximum 8 times per day).
• •11. Have a serious history of systemic infection or require hospitalization and/or intravenous anti-infective therapy (e.g., antibiotics, antifungal agents, antiviral agents) for ≥3 days within 12 weeks prior to screening.
• •12. Patients with eye infections, e.g., ocular herpes simplex, Conjunctivitis infective (except Conjunctivitis associated with seasonal allergic rhinitis).
• •13. Participants who plan to travel to areas outside their permanent residence (i.e., leaving the area of seasonal allergy exposure) for more than 2 consecutive days or more than 3 cumulative days (not consecutive) during the study period.
• •14. History (at present) of immunodeficiency infection (e.g., Pneumocystis jirovecii pneumonia, Histoplasmosis, Coccidioidomycosis); or other known Immunodeficiency.
• •15. History of lymphoid proliferative disease (current); or signs or symptoms of lymphoid proliferative disorder or any known neoplasm malignant, or history of or current neoplasm malignant (except completely resected and without evidence of recurrence squamous cell carcinoma of skin or basal cell carcinoma or cervix carcinoma in situ) within 5 years prior to screening.
• •16. Major surgery within 8 weeks prior to screening.
• •17. Uncontrolled hypertension (Blood pressure systolic ≥160 mm Hg and/or Blood pressure diastolic ≥100 mm Hg, determined by two consecutive raised blood pressure readings).
• •18. Other significant uncontrolled cardiovascular diseases at screening (e.g., infarct myocardial \[MI\], Angina unstable, moderate to severe \[New York Heart Association (NYHA) III/IV grade\] cardiac failure or cerebrovascular accident \[CVA\]), respiratory.
• •19. Hepatic, renal, gastrointestinal, endocrine, hematological, psychological, or neurological disorders, or any of the following (including but not limited to the following) as determined by the investigator are not suitable for participation in this study.
• •20. Use of prohibited medications listed in Table 2 without meeting the washout requirements in Table 2.
• •21. Concomitant medications that may affect the evaluation of efficacy of the investigational product after long-term use (including but not limited to: tricyclic antidepressants, monoamine Coproporphyrinogen Enzyme inhibition, etc.).
• •22. Use of immunotherapeutic agent or immunosuppressive/immunomodulatory drug within 60 days prior to screening (acceptable if topical use of pimecrolimus cream or tacrolimus within 30 days prior to screening and stable dose is maintained during the study).
• •23. Use of \>1% Hydrocortisone or equivalent topical glucocorticoid within 30 days prior to screening; use of topical Hydrocortisone or equivalent at any concentration covering \>20% of Body surface area; or presence of a condition that may require treatment with such preparations during the clinical study (as judged by the investigator).
• •24. Use of traditional Chinese medicine therapy for treatment of seasonal allergic rhinitis within 4 weeks prior to the screening.
