HDM and Silver Birch NAC Standardisation

Allergic Rhinitis

This study aims to establish dose-responses to nasal allergen challenge using silver birch pollen and house dust mite allergen extracts in participants with allergic rhinitis, sensitised to either or both of these allergens. The allergen extracts used will be Itulazax tablets (silver birch pollen allergen sublingual tablets, ALK-Abello, Denmark) and Acarizax tablets (house dust mite allergen sublingual tablets, ALK-Abello, Denmark). The results will allow identification of the dose of each allergen typically producing a moderate severity response, which could then be used in future, interventional and investigational studies. A control group - healthy individuals with no allergic rhinitis - will be recruited to demonstrate the absence of an irritant/non-allergic effect of the nasal allergen challenge procedure.

Seasonal Allergic RhinitisRhinoconjunctivitis

The PQGrass306 (G306) clinical trial is the pivotal Phase III efficacy clinical trial of PQ Grass. The aim of the G306 pivotal clinical trial is to confirm the efficacy and safety of the optimal effective dose of PQ Grass 27600 SU. This will be determined through the measurements of the effect of PQ Grass on the symptoms of seasonal allergic rhinitis (SAR)/rhinoconjunctivitis and the use of relief medications to control these symptoms during the peak grass pollen season (GPS).

The primary goal is to investigate the efficacy of intralymphatic immunotherapy (ILIT) for the treatment of allergic rhinitis and allergic asthma due to sensitisation to grass pollen allergens. 60 patients with allergic rhinitis will be included and randomized to receive either Polvac (n=30) or placebo (n=30). All patients will receive three injections with 4-8 weeks interval. The injections into a inguinal lymph node is guided by sonography. Patients will record symptoms and medication use in the summer of 2022 and 2023.

Effects of Pine Cone Extract on Serum IgE Levels in Perennial Rhinitis

Perennial Allergic Rhinitis

The medicinal properties of pinecones have been used for years to treat a variety of illnesses. In the mouse model, an extract of pine cones, poly-phenylpropanoid-polysaccharide complex (PPC), has been shown to reduce total serum IgE levels as well as decreased production of IL-4, a cytokine associated with allergic disease. In this study, the investigators aim to determine the effects that PPC will have on total serum IgE levels in adult subjects with perennial rhinitis.
