Inclusion criteria

Inclusion criteria: Patients have seasonal grass pollen induced rhino conjunctivitis during the two most recent seasons and a positive skin prick test resulting in a wheal diameter = 3 mm to ALK Soluprick Grass 225. The latter is important as it predicts that the patients IgE recognises allergens found in ALKs preparation for treatment, a crucial condition for treatment success. Patients are adults; more than 18 years old on the day of first treatment, Patients must be comfortable with digital data entry and have accepted and digitally approved the informed consent document. Patient have to have sufficient symptoms during the grass pollen season to allow us to record an effect of the treatment; we will evaluate question 1 – 6 and 18 – 22 of their RHINE III and the sum of the retrospective RTSS questionnaires from the pre-screening tools to assess the severity of grass pollen dependent rhinoconjunctivitis and to identify or predict possible grass pollen dependent asthma affecting patients. For inclusion, patients have to have a retrospective RTSS score >7 on a scale of 0 – 18 (most severe). We will select patients with the highest RTSS score. 90% of patients included for the baseline year will be included in the treatment study. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 36 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 4

Exclusion criteria

If ACE-blockers are used, they should be withdrawn after discussion with the Principal Investigator 2 weeks before first injection and until after the last injection 14 Recent or on-going hepatic or renal disease 15 All malignant diseases 16 Immuno- or chemotherapy during the last 15 years, 17 Increased bleeding tendency 18 Any other than study medication with an effect of interfering with the immune response 19 Chronic obstructive or restrictive lung disease 20 Skin diseases with barrier defect in the inguinal areas 21 Alcohol or drug abuse 22 Participation in another clinical study from visit 1-8.

Design outcomes

Primary

MeasureTime frame
Main Objective: The primary aim of the trial is to test the hypothesis that there is similar or more efficacy associated with fewer side effects of intralymphatic immunotherapy with 300 SQ-U/injection than with 1000 SQ-U/injection.;Secondary Objective: 2.1 change in specific IgE to Grass and Phl p5 with ImmunoCAP, and of grass molecules on the ISAC chip with different treatment intensities 2.2.1 Improvement in cSMS expressed as but also as mild (Well) days and severe (Hell) days , which is more patient oriented, and as response to Log10 of daily grass pollen counts. 2.2.2 We will test the predictive ability of the skin prick test as a ratio of the histamine positive control (Cha) for cSMS 2.2.3 Effect of treatment arms on the well standardised Junipers RQLQ on a weekly basis during the grass pollen season 2021. 3. Safety assessment;Primary end point(s): The primary endpoint is a comparable or better reduction in median cSMS due to treatment with 300 SQ-U Allergen compared with patients treated with 1000 SQ-u during the grass pollen season of 2021;Timepoint(s) of evaluation of this end point: Change in parameters between groups in the grass pollen season after treatment.

Secondary

MeasureTime frame
Secondary end point(s): Change in skin prick test from before treatment (Spring 2021) to after the first season after treatment (Autumn 2021) in the group treated with 300 SQ-U is similar or better than in the group treated with 1000 SQ-U. Change in Junipers RQLQ in the group treated with 300 SQ-U is similar or better than in the group treated with 1000 SQ-U. Change in IgE and IgG4 is similar or better in the group treated with 300 SQ-U is similar or better than in the group treated with 1000 SQ-U ;Timepoint(s) of evaluation of this end point: Change in skin prick test before treatment to after the season after treatment. Change in other parameters between groups in the grass pollen season after treatment, as well as in the second season after treatment.
