Trial Outcomes & Findings for The Safety and Efficacy of Intralymphatic Immunotherapy in Pollen Allergic Adolescents and Young Adults With Asthma (NCT NCT03394508)

NCT ID: NCT03394508

Last Updated: 2020-09-28

Results Overview

0,1 ml of ALK Aquagen birch or timothy 10 000 SQU/ml is deposited in each nostril and allergy symptoms are recorded. Symptoms during NPTs were scored according to the Lebel scoring scale. Symtom scores at 5, 15, and 30 minutes after nasal administration of the allergenextract were summed to represent the symptom-score at each nasal challenge (at inclusion, 12 months after inclusion and for the active patients 24 months after inclusion). The scoring system identifies nasal, eye, and ear symptoms: rhinorrhea, nasal pruritus, nasal congestion, ocular pruritus, watery eyes, and itchy ears, each graded on a scale from 0 to 3 points, and a total score was summarized after subtracting the starting score (min score is 0 and maximum score is 54 + the number of sneezes). Higher scores mean worse outcome.

PRIMARY outcome

Timeframe: At inclusion (pre-treatment), 12 months after inclusion (after first pollen season) and for the active treated patients 24 months after inclusion (after the second pollen season).

Population: Patients were injected 3 times before the start of the first pollen season. The study was unblinded at a follow-up visit after the end of the first season. Active patients returned for a booster injection (1000 SQ-U) before the second season and performed a new follow-up. Eleven patients (6 active, 5 placebo) did not have full analysis data sets.

0,1 ml of ALK Aquagen birch or timothy 10 000 SQU/ml is deposited in each nostril and allergy symptoms are recorded. Symptoms during NPTs were scored according to the Lebel scoring scale. Symtom scores at 5, 15, and 30 minutes after nasal administration of the allergenextract were summed to represent the symptom-score at each nasal challenge (at inclusion, 12 months after inclusion and for the active patients 24 months after inclusion).

Asthma control 4 weeks before follow-up was estimated with the asthma control test. The score is based on a questionnaire with 5 questions concerning the patients asthma. Each question can be given a score from 1 to 5 points. The answers for each question is added together, where a minimum score of 5 and a maximum score of 25 can be obtained. Higher scores indicate improved outcome and a score of 19 or less suggests poorly controlled asthma.

Modified Symptom scores and Medication score were calculated taking into account the frequency: daily (4 points); every second day (3 points); 1 to 3 days per week (2 points); occasionally (1 point); never (0 points), for the following symptoms: blocked nose, rhinorrhea, fatigue, sneezing, and asthma symptoms, and for the following medications used: local and systemic antihistamines, nasal steroids, asthma medication, and eye drops. A minimum score of 0 and a maximum score of 20 points for symptoms and 16 points for medication could be obtained. Higher values indicate worse outcome.

Methacholine challenge to test the bronchial hyperresponsiveness in the airways of the included subjects. The subject will inhale increasing doses of methacholine. Spirometry is performed before and between each inhalation. The cumulative dose of methacholine needed to elicit at 20% decrease in FEV1 (PD20) is reported. Lower values indicate worse outcome.
