| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To evaluate efficacy of Dymista in relief of nasal symptoms in Chinese adolescents, having moderate to severe seasonal and/or perennial AR with or without ocular symptoms |
|
| E.2.2 | Secondary objectives of the trial |
| To evaluate both efficacy in relief of further AR associated symptoms and safety of Dymista in Chinese adolescents, having moderate to severe seasonal and/or perennial AR with or without ocular symptoms |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
| The Inclusion Criteria for the study focus on enrolling Chinese participants aged 12–17 years who have moderate-to-severe seasonal and/or perennial AR, with or without ocular symptoms. Participants must show signs of Immunoglobulin E (IgE)-mediated hypersensitivity confirmed by diagnostic tests, have acute allergic rhinitis symptoms at inclusion, and be in general good health. They must also be able to use Dymista nasal spray correctly, agree to complete study requirements such as the patient diary, and provide informed consent/assent along with their legal guardians. |
|
| E.4 | Principal exclusion criteria |
| The Exclusion Criteria aim to ensure participant safety and study integrity. Individuals with known allergies to Dymista or its components, pregnant or breastfeeding females, or those unable to comply with study requirements are excluded. Additional exclusions include nasal conditions that interfere with drug delivery, recent nasal or sinus surgery, chronic sinusitis, recent use of investigational drugs or certain medications, respiratory infections, asthma (except mild intermittent), and recent immunotherapy. Individuals anticipating significant environmental changes are also excluded. |
