About this trial
This study aims to compare the efficacy and safety of DW1807 and DW1807-R2 in patients with perennial allergic rhinitis and comorbid asthma. The primary objective is to demonstrate the superiority of DW1807 over DW1807-R2 in improving the reflective total nasal symptom score (rTNSS) after 4 weeks of treatment.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Male or female adults aged 19 years or older.
Individuals with a confirmed history or treatment record of perennial allergic rhinitis for at least 2 years at the time of screening.
Individuals who have a positive result on an allergy skin prick test or serum allergen-specific IgE antibody test (e.g., MAST or ImmunoCAP) conducted within 1 year prior to screening, and have a documented history of allergy to at least one perennial allergen (e.g., house dust mites, cats, dogs, molds, etc.).
Individuals diagnosed with asthma classified as Step 2 to Step 4.
Disqualifiers
Individuals diagnosed with non-allergic rhinitis of other causes.
Individuals with a documented acute exacerbation of asthma within 12 weeks prior to screening.
Individuals diagnosed with pulmonary diseases other than asthma.
Individuals with nasal polyps or other clinically significant nasal structural abnormalities.
