NCT03394508

Brief Summary

The study evaluates the safety and efficacy of intralymphatic allergen-specific immunotherapy given to adolescents and young adults who are allergic to grass or birch pollen and have mild or moderate asthma. Patients will be treated with three intralymphatic injections; 1000 SQ-U x3 with 4-5 weeks interval, or placebo with 4-5 weeks interval. The patients receiving treatment will be given a fourth injection one year after the initial injections. The study is conducted in collaboration between Professor Lars Olof Cardell (ENT), prof Gunilla Hedlin (Pediatrics) and prof Marianne van Hage (Immunology)".

Outcome Measures

Primary Outcomes (1)

  • Change in Symptoms Score After Nasal Allergen Challenge

    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.

    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).

Secondary Outcomes (9)

  • Change on Visual Analogue Scale (VAS

    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).

  • Change in Quality of Life

    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).

  • Change in Allergen-specific Serum Immunoglobulin E (IgE) Levels Compared to Before Treatment

    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).

  • Change in Asthma Symptom Scores

    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).

  • Change in Pulmonary Function Measurement (Spirometry)

    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).

Eligibility Criteria

Age16 Years - 50 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Allergic rhinitis due to grass or birch pollen
  • Mild to moderate asthma with a positive methacholine challenge
  • Accepted and signed informed consent.

You may not qualify if:

  • Previously subcutaneous immunotherapy (SCIT) with total symptom relief.
  • Previously SCIT but no symptom improvement at all.
  • Sensitizations to house dust mite or furry animals, with ongoing exposure and symptoms.
  • Severe atopic dermatitis.
  • Patients with significant diseases other than allergic rhinitis. A significant disease is defined as a disease which in the opinion of the investigator may either put the patient at risk because of participation in the study or a disease which may influence the results of the study or the patient's ability to participate in the study.
  • Patients with a respiratory tract infection in the past 4 weeks prior to Visit 2.
  • Pregnant or nursing women or women of childbearing potential not using a medically approved means of contraception (i.e., oral contraceptives, intrauterine devices, diaphragm, or subdermal implants).
  • Known autoimmune or collagen disease
  • Cardiovascular disease
  • Hepatic disease
  • Known renal insufficiency
  • Cancer
  • Hematologic disease
  • Chronic infectious disease
  • Any medication with a possible side-effect of interfering with the immune response
  • +9 more criteria
