Active clinical trials for "Rhinitis, Allergic, Seasonal"

Study aiming to evaluate the efficacy of a 2-month pre-seasonal treatment with an AllerT 50 µg or 100 µg maintenance dose administered in previous study AN004T in reducing symptoms of allergic rhinoconjunctivitis during the 2nd following birch pollen season.

This research aims to establish a panel of inflammatory biomarkers of the early (Histamine, Tryptase, ProstaglandineD2) and late (Interleukin-4, Interleukin-5, Interleukin-6, Interleukin-13, Eotaxin, Tumor necrosis factor-a (TNF), (Macrophage Inflammatory Protein-1beta (MIP1ß)) phase response to nasal bolus allergen challenge (NAC) in subjects with out-of-season seasonal allergic rhinitis, suitable for future application in drug intervention studies of novel anti-allergy therapeutics.

The purpose of this study is to collect information on unexpected adverse reactions (ADRs), how often ADRs occur, and factors that can affect the safety and effectiveness of Claritin (loratadine) when used in children. Patients will be observed while they are taking Claritin, and ADRs and symptom scores will be recorded. At the end of treatment, improvement in symptoms will be recorded. Post-marketing surveys are not considered applicable clinical trials and thus the results of this survey will not be posted at its conclusion. The results will be submitted to public health officials as required by applicable national and international laws.

The purpose of this study is to establish whether MRI scanning is a sensitive measure of the effects of existing drug treatments on nasal dimensions following challenge with intranasal allergen in subjects with hayfever. If successful this technique could be applied to increase confidence for internal decision making and ultimately may be used to assess how effective a new drug treatment is.

The objective of this study is to determine whether there is a relationship between interferon-gamma levels and the incidence of viral respiratory infections in allergic children treated with allergy immunotherapy as compared to those treated with standard medical care (nasal steroids, antihistamines) over a 1-year period. The hypotheses to be tested are 1) interferon-gamma levels will be significantly increased 3, 6, 9 and 12 months in allergic children treated with allergy immunotherapy as compared to those treated with standard medical care, 2) the incidence of viral respiratory infections will be reduced at 3, 6, 9 and 12 months in allergic children treated with allergy immunotherapy as compared to those treated with standard medical care.

The aim of this study is to assess the nasal and conjunctival response in subjects allergic to birch pollen during controlled exposures in the ALYATEC environmental exposure chamber (EEC)

This prospective open multi-centre non-interventional study initiated to document the up-dosing period of children and adults with allergic rhinoconjunctivitis and/or allergic asthma treated with a SLIT containing purified, aqueous extracts of birch, alder, and hazel pollen. The following up-dosing schemes are freely selectable: scheme A consists of an up-dosing period of 12 days at the patient´s home using the standardized pollen extract in three different solution strengths to reach the maximum dose; scheme B is performed only with the highest solution strength at the physician's office within 2 hours; and the new scheme C which is a regimen for initiation at the physician's office and continuation at the patient's home also exclusively using the highest solution strength and takes 4 days. Data are documented by physicians and in patients´ diaries.

This is a post-marketing surveillance study on a marketed cetrizine hydrochloride formulation.

The purpose of this study is to find out how the provocation of the nose changes breathing style (specifically, frequency and tidal volume changes)

The aim of this observational study is to document the therapeutic use of PASCALLERG ® for hay fever. Based on the survey is a decrease in disease-specific symptoms when taking PASCALLERG ® over a period of 4 weeks will be documented. In addition to the compatibility can be assessed.
