NCT06046391
Allergic rhinitis (AR) affects large population worldwide, the most commonly used medication include anti-histamine, nasal spray and anti-LTRAs inhibitors (leukotriene receptor antagonists), Even after those first-line treatment, there is still a large number of patient (\~20%) are not well/adequately controlled. Anti-IgE antibody has been approved to treat moderate to severe AR by PMDA/Japan in 2020, demonstrating the efficacy of IgE blockade in the treatment of allergic rhinitis. The current study presents a novel anti-IgE antibody (LP-003) with higher affinity to IgE, stronger efficacy and longer half-life.

NCT04815668
Allergic rhinitis (AR) is an immunoglobulin E-mediated inflammatory disease1 caused by hypersensitivity of the immune system to an allergen, affecting 100 million people in Europe 2and 400 million of the global population.The etiology of AR is multifactorial, resulting primarily from genetic predisposition, immunological response, and environmental pollutants.AR traditionally has been classified as seasonal (SAR) or perennial (PAR) depending on the causes and duration of symptoms. Some patients with AR prefer complementary and alternative medicine for their symptoms, with nearly 20% receiving acupuncture. According to the updated practice parameter of rhinitis in 2020, the use of acupuncture for the treatment of AR was not recommended due to a lack of well-controlled studies. The sphenopalatine ganglion (SPG), located under a thin (1-2 mm) layer of mucosa in the pterygopalatine fossa, consists of sensory fibers that innervate the nasopharynx, nasal cavity, and palate.Several studies have reported the benefit of SPG stimulation in chronic cluster headache and acute ischaemic stroke. Compared with traditional acupoints selected on basis of traditional meridian theory, acupuncture at SPG(inserting a needle through SPG acupoint (near ST7, Xiaguan) to reach and directly stimulate the SPG) may help patients ameliorate nasal symptoms immediately and improve quality of life by increasing sympathetic nerve excitability, but the evidence is inconclusive. We have designed this three-armed, randomized trial to investigate the efficacy and safety of acupuncture at SPG for the treatment of SAR. We hypothesize that acupuncture at SPG plus rescue medication is superior to sham acupuncture plus RM and RM alone in the treatment of SAR.
NCT06837233
The study is a multicenter, randomized, double-blind, placebo-controlled seamless and adaptive-designed phase IIb/III study encompassing a phase IIb and a phase III component. The phase IIb study, which is registered this time, is a dose-ranging component. The phase III study is a pivotal part of the overall research. The goal of this phase IIb study is to evaluate the efficacy, safety, and pharmacokinetics of PG-011 nasal spray across various dosages and administration frequencies for treating adults with moderate to severe seasonal allergic rhinitis (SAR). Investigators will compare PG-011 nasal spray to a placebo (a look-alike substance that contains no drug) to see which dosage and frequency works to treat moderate to severe seasonal allergic rhinitis.
NCT06846385
A multicenter, randomized, double-blind, placebo-controlled Phase II/III seamless clinical study evaluating the efficacy, safety, pharmacokinetic (PK) profile, pharmacodynamic (PD) profile, and immunogenicity of MG-K10 humanized monoclonal antibody injection in the treatment of seasonal allergic rhinitis
NCT05540717
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).
NCT02320396
This is an efficacy and safety study of desloratadine (MK-4117) in Japanese participants with seasonal allergic rhinitis (SAR). The primary hypothesis of this study is that the change from Baseline in Total Nasal Symptom Score (TNSS) is improved by desloratadine compared to placebo.
NCT04817800
An open label, randomized, three-treatment, three-period, crossover, single dose study, to investigate drug-drug interaction and relative bioavailability between the fixed dose combination Azelastine hydrochloride / Beclomethasone dipropionate (140/100 μg Azelastine hydrochloride / Beclomethasone dipropionate) Nasal Spray, and Beclomethasone Dipropionate Nasal Spray (100 μg Beclomethasone Dipropionate) in the test vehicle, and the commercially available product, RinoClenil® Nasal Spray (100 μg Beclomethasone Dipropionate), in healthy subjects under fasting conditions.

NCT04489121
Allergic rhinitis (AR) is induced by an immunoglobulin E (IgE)-mediated reaction in the allergen-sensitized subjects, affecting 10% to 40% of the world population. AR could be divided into two kinds, perennial AR and seasonal AR (SAR). In recent years, biologics have become promising drugs for allergic diseases. The efficacy and safety of Omalizumab in treating SAR have been well proven by previous studies. However, the efficacy in preseasonal treatment for SAR has not yet been studied before.
NCT04709614
Objective biomarker of allergic rhinitis severity is necessary for monitoring disease severity and response to treatment in clinical setting and for research. We believe that psychological factors are the missing link between patient-perceived severity of allergic rhinitis and objective biomarkers. In our pilot study, several psychological factors were studied in relation to patient reported outcomes for severity of allergic rhinitis.

Study includes male and female subjects, aged 18 and 65 years with clinical history of SAR with seasonal onset and offset of nasal allergy symptoms during each of the last two ragweed allergy seasons and a positive skin prick test to ragweed allergen within 12 months prior to randomization.
NCT00574379
Evaluate the relative efficacy of four dosing regimens of bilastine tablets (given either once or twice per day) versus placebo in patients with Seasonal Allergic Rhinitis (SAR) in the Mountain Cedar season in south Texas and Oklahoma based on the mean change from baseline in Reflective Total Nasal Symptom Scores (TNSS) assessed over 14 days of treatment.
NCT00346086
Various chemical modifications of allergens have been attempted to enhance efficacy, improve safety, and foster compliance with IT. These approaches have been unsuccessful - in that the allergenicity and immunogenicity have either decreased, or increased in tandem, with no resultant efficacy: safety benefit ratio. This study utilizes an adjuvant approach in which synthetic immunostimulatory DNA is conjugated to ragweed allergen in an attempt to modulate both the clinical and immunologic allergic response to ragweed exposure in ragweed-allergic patients with seasonal rhinitis.
