NCT02255604

Brief Summary

The investigators want to investigate whether specific immunotherapy can be delivered directly into a lymph node. The investigators think that a direct introduction of allergen to the antigen presenting cells in the lymph node a give a strong immune response and that this can change the number of injections needed in allergen immunotherapy. The investigators do measurements of clinical effect and a variety of paraclinical test to see if the investigators can find af biomarker of successful specific immune therapy of grass allergy.

Outcome Measures

Primary Outcomes (1)

  • Change in cSMS (Combined Symptom and Medication Score)

    cSMS, Combined symptom and medication score, during grass pollen season in three years follow up. Minimal score 0, Maximal score 18. Higher score means worse outcome. Scale: Itchy/red eys: 0-3, Runny eyes: 0-3, Itchy nose: 0-3, Runny nose: 0-3, Block nose: 0-3, Sneezes: 0-3. Topical antihistamine 1.5 points/1 point. Nasal corticosteroid: 1 point/2 points. Oral antihistamine: 6 points/1 point. Oral prednisolon 1.5 point /3 points. Elements are summed to a combined score. Different combination methods exists. EAACI recommends means, i.e. symptoms 0-3 plus medicationscore 0-3. This scoringsystem was applied in the last follow-up year.

Study Arms (3)

intralymphatic immune therapy

ACTIVE COMPARATOR

Lymphnodes in the groin are identified with ultrasound. Under ultrasound guide they are injected with 0,1 ml of alk 225 Phleum Pratense 10,000 standard quantity units/ml. Patients receive 4 injection in total. 3 injection in the spring 2014 with one month interval and 1 injection in the spring 2015.

Drug: Alk (225) Phleum Pratense. 0.1 ml of 10,000 standard quantity units/ml.

3 intralymphatic immune therapy

PLACEBO COMPARATOR

Lymphnodes in the groin are identified with ultrasound. Under ultrasound guide they are injected with 0,1 ml of alk 225 Phleum Pratense 10,000 standard quantity units/ml. Patients receive 3 injection in total. 3 injection in the spring 2014 with one month interval. In in the spring 2015 patients will have a placebo injection.

Drug: alk (225) Phleum Pratense. 0.1 ml of 10,000 standard quantity units/ml.

no intralymphatic immune therapy

SHAM COMPARATOR

Lymphnodes in the groin are identified with ultrasound. Under ultrasound guide they are injected with 0,1 ml of isotone saline. Patients receive 4 injection in total. 3 injection in the spring 2014 with one month interval and 1 injection in the spring 2015. All injections are with isotone saline as placebo control.

Drug: 0.1 ml Isoton saline

Interventions
