Comparing two nasal sprays for treating seasonal allergies

A Multicenter, Randomized, Double-blind, Three-arm, Parallel Clinical Endpoint Bioequivalence Study of Monometasone Furoate Nasal Spray in Patients With Seasonal Allergic Rhinitis

This study is testing if a new nasal spray works as well as an existing one to help people with seasonal allergies feel better.

What this trial studies

This clinical trial evaluates the bioequivalence of two nasal sprays, Mometasone furoate and a reference preparation, in patients suffering from seasonal allergic rhinitis. It is a multicenter, randomized, double-blind, three-arm study designed to assess the safety and efficacy of the test agent compared to the reference. Participants will be monitored for their nasal symptoms and overall response to treatment over the course of the trial. The study aims to provide evidence on whether the new nasal spray is as effective as the established treatment.

Who should consider this trial

Good fit: Ideal candidates are men and non-pregnant women aged 18 to 65 with moderate to severe seasonal allergic rhinitis and a documented history of allergy.

Not a fit: Patients with mild allergic rhinitis or those who do not meet the specific inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide patients with a new effective option for managing seasonal allergic rhinitis.

How similar studies have performed: Previous studies have shown success in evaluating bioequivalence of nasal sprays, indicating that this approach is supported by existing research.

Screening of alcohol addicts or drug users in the first 2 years (Visit 1); 5. Select (Visit 1) for nasal trauma who had sinus surgery or incomplete healing within 3 months; 6. Those who have participated in other drug clinical trials and used study drugs within 3 months prior to screening (Visit 1); 7. Those who were vaccinated within 7 days prior to screening (Visit 1) or who are scheduled to be vaccinated during the trial; 8. Presof glaucoma, cataract, ocular herpes simplex, infectious conjunctivitis or other eye infections during screening (Visit 1); 9. Local or systemic fungal, bacterial, viral or parasitic infection with active or inactive pulmonary TB infection at the screening (Visit 1), not cured and still requiring continuous treatment, the subject may be at risk of discomfort or affect the judgment of the test results; 10. Patients with asthma requiring long-term treatment (occasional acute asthma, or mild, exercise-induced asthma, unmedicated or limited to inhaled short-acting β receptor agonists during the trial (patients with a maximum of 8 doses per day can be included)); 11. Screening period or randomized anterior nasal examination results judged by the investigator of nasal diseases or symptoms / signs that may affect the intranasal drug deposition, such as acute or chronic sinusitis, chronic purulent symptoms or signs of the postnasal drip, drug rhinitis, significant nasal polyps, other clinically significant respiratory tract malformations / nasal structure abnormalities, significant nasal trauma (e. g., nasal penetration injury), or significant nasal septum deviation; 12. Patients with any nasal mucosa erosion, septal ulcer or septal perforation during screening or before randomization; 13. The following drugs and / or patients were used during the 7 half-lives before the lead-in period (see Appendix 2): vasoconstrictors (3 days), strong sedative (3 days), antihistamine (3-10 days), decongestants (3 days), leukotriene receptor antagonists (7 days), anticholines (7 days), sweet acids (14 days), systemic antibiotics (14 days), ocular mast cell stabilizers (14 days), monoamine oxidase inhibitors (14 days), tricyclic antidepressants (14 days), potent CYP3A4 Induction / inhibitor (14 days), anti-allergic Chinese herbs (14 days), Corticosteroids (14-30 days), immunotherapy (60-120 days), etc.; 14. planned use of the following drugs or / and treatment during the trial: a. potent CYP3A4 induction / inhibitor; b.
