Active clinical trials for "Rhinitis"

This is a single group, Phase IV clinical trial to assess the safety and effectiveness of Allegra® D. This study will be conducted in participants with allergic rhinitis who are 12 years of age and above. The individual study duration for each participant would be approximately 16 days (maximum of 13 days intervention + a 3-day post intervention observation). There would be 4 study visits in which the last visit can be done either telephonically or on site. Safety events would be captured for the entire study duration. In addition, the effectiveness of the study drug would be assessed using Nasal symptom score (NSS) and Total symptom score (TSS).

Allergic diseases such as asthma, allergic rhinitis (AR) and atopic dermatitis affect more than 25% of the world population and are the leading cause of illness in children. The complex interplay between genetic, environmental and immunological risk factors results in the manifestation of allergic diseases . The pathological presentation of allergic disease involves the activation of both the innate and adaptive immune systems, resulting in a multifaceted response in specific target tissues such as the airways . This response results in the recruitment of inflammatory cells to target tissues and the production of specific IgE antibodies, cytokines and other inflammatory mediators [11], [12]. It is well established that allergic inflammation triggers neuronal dysfunction, which activates specific inflammatory mechanisms, potentially leading to structural changes in the diseased tissue . Neurotrophins are a family of structurally related proteins initially discovered to be involved in regulating neuronal development and now known to govern both peripheral and central nerve growth. BDNF is a secretory protein belonging to the neurotrophin family and is involved in a range of neural processes during human development [19], [20]. In the early stages of development BDNF is essential for neurogenesis, survival and maturation of neuronal pathways. In the adult, alongside neurotransmitters, hormones and other neurotrophins, BDNF maintains synaptic plasticity, dendritic growth and the consolidation of long-term memory. The biological effect of BDNF is mediated via its binding to the trkB receptor. The activation of these receptors on eosinophils may be important in regulating the inflammatory cascade leading to allergic disease [15], [24]. Neurotrophin mediated activation of bronchial eosinophils might therefore play a role in the regulation of eosinophilic inflammation in allergic asthma . The BDNF gene is located on chromosome 11p13 and is alternatively spliced resulting in several different transcripts [26]. Genetic polymorphisms in BDNF have been associated with allergic phenotypes such atopic dermatitis [27] and asthma [28], [29], [30], [31] in different populations. The functional polymorphism rs6265 (Val66Met) has been shown to regulate intracellular trafficking and affect the secretion of BDNF [32]. Nerve growth factor (NGF), a neurotrophin that is expressed in the glandular, nasal epithelium, and peripheral nerves in the nasal mucosa, has been shown to induce biochemical and structural changes in nerves that can lead to hyper-responsiveness [33], [34], [35] The biological effects of neurotrophins are mediated by binding either to the high-affinity tyrosine kinase (trk) receptors or to the low-affinity receptors known as pan-neurotrophin receptor p-75.

This study is a multicenter, single arm, open-label phase II clinical study mainly evaluating the safety of CM310 in patients with allergic rhinitis.

Gathering knowledge on the use of Dymista® in Asian patients who receive Dymista® for the first time in routine clinical practice

Allergic rhinitis is a common and recurrent ear, nose and throat (ENT) disease. It is a chronic or seasonal condition affecting 10% to 20% of the world's population. It is considered one of the most difficult diseases to treat globally and has become a major global health problem. SUblingual immunotherapy (SIT) is currently considered to be an effective pairings therapy that can alter the natural progression of allergic rhinitis through immunomodulatory mechanisms. Immunotherapy is more suitable for patients with moderate to severe intermittent or persistent allergic rhinitis, especially for those with poor drug treatment. This treatment can significantly reduce the severity of allergic rhinitis, reduce the use of allergy medications, and improve the quality of life for many patients. In the development of allergic rhinitis, the regulation of immune balance in Th1 / Th2 / Th17 cells is currently considered to be an important approach in the treatment of allergic rhinitis. But a growing body of evidence suggests that an intrinsic immune response is also the pathogenesis of allergic rhinitis. Innate lymphocytes are involved in mucosal immune formation, lymphocyte development, tissue damage repair and epithelial barrier protection, and play an important role in fighting infection, regulating inflammation and maintaining immune homeostasis. Three subsets of intrinsic lymphocytes (ILC1s, ILC2s, ILC3s) have been proposed to functionally approximate Th1, Th2, and Th17 in helper T lymphocytes (Th), but the results are inconclusive and the mechanism of ILCs role in AR progression is not fully elucidated. Therefore, the purpose of this study was to investigate the efficacy and mechanism of subglossal immunotherapy for perennial allergic rhinitis, and to reveal the correlation between ILCs (ILC1s, ILC2s, ILC3s) and Th1 / Th2 / Th17 cell immunity, and to provide a basis for clinical studies of allergic rhinitis.

Single-center, case-control, longitudinal, observational, population based cohort study with stratified sample (by age group, gender, and residential area).

This is a multicenter, randomized, double-blind, placebo-controlled phase III clinical study aimed at evaluating the efficacy and safety of CM310 in patients with seasonal allergic rhinitis, and observing the quality of life, PK, PD characteristics, and immunogenicity of subjects.

Allergic rhinitis is a disease in which the nasal mucous membrane overreacts to allergens, resulting in symptoms such as spasmodic and repetitive sneezing, rhinorrhea, and stuffy nose, and can be treated with immunotherapy for radical treatment. Immunotherapy treatments include subcutaneous injections, sublingual tablets, and sublingual fluids, and subcutaneous injections have the risk of anaphylaxis, the hassle of daily administration at home, and local allergic reactions. Transdermal absorption immunotherapy (DF19001) that can compensate for the shortcomings of these existing immunotherapy drugs is currently under clinical research in Korea (Severance Hospital IRB No. 4-2021-1345). Immunotherapy requires periodic monitoring, such as analyzing immunological changes through sample collection and determining the dose and cycle of administration, because the treatment period is long and individual immune responses are different. Existing methods for confirming immune responses in samples used invasive skin biopsy and blood collection methods, but in-blood evaluation indicators have the disadvantage of being ineffective as initial efficacy evaluations or predictive evaluations before treatment. In addition, skin biopsy should be performed by a specialist, and there is a disadvantage that resistance occurs because the patient's pain is accompanied, and scars or bruises may remain. Therefore, since it is a biopsy through minimal invasion compared to a tissue biopsy, the investigators would like to use a method of collecting skin samples through a microstructure (micro needle patch), a method that has little pain and no scars. Through this study, RNA is obtained from patients with house dust mite allergic rhinitis through minimally invasive skin samples, and immunotherapy response evaluation biomarkers are screened according to immunotherapy implementation, and its use as an indicator of immunotherapy prognosis in allergic diseases.

The combined use of dexamethasone and oxymetazoline has a vasoconstrictive, anti-inflammatory and anti-allergic effect when applied topically in diseases of the upper respiratory tract. The main goal of this research is Evaluation of the effectiveness of Dospray® nasal spray in the treatment of persistent allergic rhinitis. The study will involve 126 patients diagnosed with allergic rhinitis: Patients taking Dospray = 63 Patients on other alternative treatment = 63 Duration of Patient Participation - 7-10 days (duration of treatment for an individual patient).

The study is designed to assess whether allergic rhinitis and allergen immunotherapy affect the humoral response to SARS-CoV-2 Vaccination in adults. This is a prospective study enrolling a total of approximately 120 subjects, 18-55 years old.
