Efficacy and Safety of LP-003 in Moderate-to-severe Seasonal Allergic Rhinitis Adult
Study Details
Study Description
Brief Summary
Allergic rhinitis (AR) affects large population worldwide, the most commonly used medication include anti-histamine, nasal spray and anti-LTRAs inhibitors (leukotriene receptor antagonists), Even after those first-line treatment, there is still a large number of patient (~20%) are not well/adequately controlled. Anti-IgE antibody has been approved to treat moderate to severe AR by PMDA/Japan in 2020, demonstrating the efficacy of IgE blockade in the treatment of allergic rhinitis. The current study presents a novel anti-IgE antibody (LP-003) with higher affinity to IgE, stronger efficacy and longer half-life.

Detailed Description
The purpose of this study was to evaluate the efficacy and safety of LP-003 in combination with SoC (nasal corticosteroids and/or anti-histamine) in adult patients with Moderate to Severe Seasonal Allergic Rhinitis, whose symptoms were inadequately controlled despite the current recommended therapies (nasal corticosteroids and/or anti-histamine) in the previous 2 pollen seasons.

Outcome Measures
Primary Outcome Measures
- Mean nasal symptom score [peak pollen period(estimated average 4 weeks)]
Nasal symptoms (itchy, sneezing, rhinorrhea and nasal congestion) were recorded by the patient everyday in their e-Diary, on a scale of 0 (none) to 3 (intense/severe). Nasal symptom score (0-12 point) consisted of score for severity of itchy (0-3 point), sneezing (0-3 point), rhinorrhea (0-3 point) and nasal congestion (0-3 point). Peak pollen period was defined as the period between the first and last three consecutive days with ≥300 total pollen/1000 mm2 each day.
Secondary Outcome Measures
- Daily nasal symptom medication score [peak pollen period(estimated average 4 weeks)]
The daily nasal symptom medication score consisted of the sum of the daily nasal symptom severity score (0-12 points) and the daily nasal rescue medication score.
- Daily nasal symptom medication score [pollen period(estimated average 10 weeks)]
The daily nasal symptom medication score consisted of the sum of the daily nasal symptom severity score (0-12 points) and the daily nasal rescue medication score. Pollen period was defined as the period between the first day when the total daily pollen count was ≥80 total pollen/1000 mm2 to the first day when the total daily pollen count was <80 total pollen/1000 mm2
- Daily ocular symptom medication score [pollen period(estimated average 10 weeks)]
Ocular symptoms (itchy eyes/foreign body sensation/redness, tearing) were recorded by the patient everyday in their e-Diary, on a scale of 0 (none) to 3 (intense/severe). Ocular symptom score (0-6 point) consisted of score for severity of itchy eyes/foreign body sensation/redness (0-3 point) and tearing (0-3 point). The daily ocular symptom medication score consisted of the sum of the daily ocular symptom severity score (0-6 points) and the daily ocular rescue medication score.
