Active clinical trials for "Rhinitis, Allergic"

This randomized control trial study aims to know the effects of adding 2,5% Binahong extract on the effectiveness of NaCl 0.9% nasal irrigation in patients with allergic rhinitis. The main questions it aims to answer are: How does the efficacy of Binahong Extract 2,5% with 0,9% NaCl to mRNA expression (IL-4, Il-6, IL-13, and TNF-α)? How does the efficacy of Binahong Extract 2,5% with 0,9% NaCl to clinical symptoms? How does the efficacy of Binahong Extract 2,5% with 0,9% NaCl to quality of life? How does the efficacy of Binahong Extract 2,5% with 0,9% NaCl to physiology? Participants will use nasal irrigation two times daily for two weeks. Researchers will compare the nasal irrigation group using a combination of Binahong Extract 2,5% with the group using NaCl only to see the superior effect.

Allergic rhinitis is a common condition that affects adults as well as children and adolescents, often with impaired quality of life. Patients often report a poor level of satisfaction with the effectiveness of their treatment and are always looking for more drug combinations to improve their symptom. Several tools exist for assessing control of allergic rhinitis, but none has been validated in teenagers or in children. A study conducted in 2008, resulted in the validation of a self-administered control test of allergic rhinitis (ARCT) in patients from 12 years of age. We propose to adapt ARCT adult to pediatric population from 5 to 11 years old.

Allergic rhinitis is a chronic respiratory disorder affecting patients' quality of life and work performance. Pharmacists are identified as suitable professionals to deliver patient education and pharmaceutical care in managing allergic rhinitis (AR) patients. Local clinical practice guidelines in Malaysia are lacking, especially in pharmaceutical care in public healthcare institutions. This study protocol describes a randomised control trial (RCT) that aims to determine the effectiveness of a pharmacist-led educational model in managing AR (AR-PRISE Model) compared to standard pharmaceutical care. The AR-PRISE model delivers patient educational material (video) and an algorithm for pharmaceutical care.

The ragweed Ambrosia artemisiifolia is spreading in northern Europe due to climate change. The pollen are considered highly allergenic and might trigger allergy symptoms at much lower concentrations than e.g. grass or birch pollen. This study aims to determine threshold concentrations for ragweed and birch pollen in patients with seasonal allergic rhinitis. Participants will be exposed in an allergen challenge chamber that was technically modified to maintain very low and stable pollen concentrations for several hours. The study design is adaptive, where the pollen concentrations are escalated or de-escalated based on interim analysis of resulting allergic symptoms.

This is a mechanistic, controlled, open-label, single-site study to evaluate the effects of RG-RV16 inoculation on airway mucosal gene expression and airway remodeling in 25 healthy controls (HC), in 25 allergic rhinitis subjects (AR) with cat dander allergy, and in 25 allergic asthmatic subjects (AA) with cat dander allergy. Three groups (HC, AR, and AA) will undergo screening to establish clinical history, will undergo pulmonary function testing (spirometry), and will have blood drawn for clinical characterization (IgE, , ImmunoCAP, CBC and differential), and for assessing the presence of existing neutralizing antibody against RV16. Only those who meet criteria will be permitted to continue into the interventional and run-out phases of the study.

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.

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.

A research study of how house dust mite tablets work compared to placebo in children aged between 5 and 11 years and who have allergy to house dust mites (MATIC)

This study evaluates the effect of intramuscular injected methylprednisolone treating birch pollen induced rhinitis compared to placebo.

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).
