Evaluation of the Clinical Efficacy of PURESSENTIEL Allergy Protection Nasal Spray (SNPA®) in House Dust Mite Allergic Rhinitis- ACARAY Study

Sponsor: Puressentiel

Summary

Justification of the relevance of the research: Patients suffering from allergic rhinitis are looking for several therapeutic options to control their symptoms. Although etiological treatment is based on allergen immunotherapy, and most prescribed symptomatic therapies include antihistamines and/or topical corticoids, patients tend to self-medicate and seek different options, also choosing non-pharmacological approaches, particularly when symptoms are milder; nevertheless, accurate and reliable information on non-conventional therapies remains limited. Main research hypothesis and objectives: The present study, will prospectively investigate the potential role of Puressentiel® Protection Allergies nasal spray (SNPA) in patients suffering from house dust mite allergic rhinitis. Assessment of the benefits and risks of the research, including the expected benefits for the people who undergo the research and the foreseeable risks associated with the research treatment and investigative procedures: No individual benefit is expected. With regard to possible indirect benefits, this study could help to propose a natural, alternative solution to symptomatic medication for the symptoms of allergic rhinitis in mite-allergic patients. The main risks of this study are those linked to the performance of the nasal challenge test, i.e. the appearance of symptoms of allergic rhinitis. Justification for the inclusion of persons covered by articles L.1121-5 to L.1121-8 and L.1122-1-2 of the French Public Health Code (e.g. minors, protected adults, etc.) and procedure implemented to inform and obtain the consent of these persons or their legal representatives. Subjects over 18 years of age will be included in this project. People under court protection, guardianship or curatorship are excluded from this research. Description of the recruitment process: Patients are recruited at the time of consultation in the Division of Allergology, Department of Pneumology, Allergology and Thoracic Oncology, Hôpital Arnaud de Villeneuve - CHU de Montpellier, whatever the reason for the consultation (respiratory allergies, food allergies, drug allergies, skin allergies). Patients will be given a period of reflection before confirming their participation by signing an express consent form. Investigation procedures carried out: After a rhinitis and possibly asthma control test, patients will undergo a nasal mite challenge test, preceeded by the administration of either SPNA or placebo (saline solution)( D0). 15 days after the first test, a second test will be performed with the spray that was not administered on D0. Before, during and up to 4 hours after each nasal challenge test, the value of nasal inspiratory peak flow and a rhinitis score will be collected. Justification of whether or not there is: (1) a prohibition on simultaneous participation in other research; (2) an exclusion period during which participation in other research is prohibited/ Given the need to stop anti-allergy treatments before and during the study; participation in another study is not permitted 7 days before the start of the present study and 7 days after its end (exclusion period). Terms and amount of compensation for research participants Researchers will be compensated up to €500. Anticipated number of people to be included in the research 20 (twenty)
