Filter by:Allergy is a public health problem as more than 20% of western society is affected by it. Symptomatic treatment of allergy suffices with less severe allergy. Patients with more severe allergy should be treated with allergen immunotherapy (AIT). Present options of AIT are efficient but of long duration, associated with side effects and require much time from the patient. With Intralymphatic immunotherapy (ILIT), allergen is injected into the lymph node under ultrasound guidance. ILIT is complete after 3 treatment visits, may be more effective than and may have markedly fewer side effects than presently available methods of AIT. The investigators plan a randomized, parallel group, open-label, prospective case-control study to assess immunological changes in lymph node and peripheral blood after intralymphatic (ILIT) or subcutaneous (SCIT) immunotherapy with POLVAC. The intervention consists of one ultrasound-guided injection of allergen into inguinal lymph node or subcutaneous injection 1 cm next to the lymph node. Intervention quality (accuracy of injection) will be assessed by the administering physician during treatment and via video recording on the ultrasound device. Side effects associated with treatment will be recorded by the patients for 3 days after the injection. The effect of intralymphatic or subcutaneous injection on lymph node tissue and immunoglobulins E and G4 in serum as well as cellular analyses of lymph node tissue and peripheral blood will be determined in samples taken during the trial. The primary effect parameter is the effect of a single intralymphatic allergen injection on immunological parameters as well as allergen delivery to the lymph node as compared with a single subcutaneous injection.
This study will compare the PK parameters of the combination test formulation to monotherapy reference products (mometasone furoate and azelastine hydrochloride) in adolescents and young adult patients with seasonal allergic rhinitis.
To improve accuracy and take out human error opportunities, Hippo Dx developed S.P.A.T., an automated skin prick test. This study will provide a comparison between manual and automated skin prick test in allergic and non-allergic individuals with a panel of common inhalant allergens. The primary endpoint is to compare the accuracy of S.P.A.T. to detect sensitization to common aeroallergens compared to a manual skin prick test (SPT). It is a prospective monocentric study that will include 120 study participants.
This study is a proof-of-concept study to demonstrate if a daily dose of a 2-days pre-treatment of Fexofenadine 180mg is effective in alleviating the AR symptoms and to assess the additional benefit to the patient in terms of preventing Allergic Rhinitis (AR) symptoms. The total study duration per participant is expected at least 4 months, depending on the timing of the screening visit. 5 visits are planned, screening, confirmation inclusion challenge, randomization visit, challenge and end of study visit.
Allergic rhinoconjunctivitis due to birch pollen is a seasonal problem which manifests as a combination of nasal symptoms (such as congestion, runny nose, sneezing, itching of the nose) and ocular symptoms (such as red, itchy and watery eyes). For several birch-allergic patients, allergic rhinoconjunctivitis occurs with an oral allergy syndrome. The purpose of this study is to demonstrate the safety and efficacy of the study drug (STALORAL Birch 300 IR) in children and adolescents with birch pollen-induced allergic rhinoconjunctivitis, with or without asthma, when treated before and during the pollen season. Approximately 699 children will participate in this study. The study will be conducted worldwide in approximately 100 medical sites in about 14 countries. The total duration of the study will be approximately 20 months.
Prospective, multicenter, open, randomized, parallel, clinical study for assessment of comparative efficacy and safety of Azelastine +Mometasone Sandoz (main group) and Momat Rino Advance (control group) administered as a monotherapy to patients with seasonal allergic rhinitis (SAR).
The motivation-enhancing intervention is designed for participants in the ILIT.NU trial. The participants are patients with hay fever who are treated with a vaccination in an inguinal lymph node. The motivation-enhancing intervention is a web-based app developed in collaboration with patient partners and is intended to increase retention and reporting in the ILIT.NU trial.
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 objective of this study is to determine the biological activity of Juniperus oxycedrus and Cupressus arizonica. allergen extracts in histamine equivalent prick (HEP) units, in order to be used as in-house reference preparation (IHRP).
The objective of this study is to determine the biological activity of Quercus illex and Quercus robur allergen extracts in histamine equivalent prick (HEP) units, in order to be used as in-house reference preparation (IHRP).
