NCT03570957
The objective of this study is to investigate the safety, tolerability, and pharmacokinetics of MT-2990 in patients with Japanese cedar pollen-induced seasonal allergic rhinitis (JC-SAR). Additional objective of the study is to investigate the efficacy and pharmacodynamics profile of MT-2990 in an environmental exposure chamber (EEC) on Day 8, 29, 57, and 85.
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.
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.
NCT05590598
Prospective, multicenter, open, randomized, parallel, clinical study for assessment of comparative efficacy and safety of Azelastine +Mometasone Sandoz (main group) and Momat Rino Advance (control group) administered as a monotherapy to patients with seasonal allergic rhinitis (SAR).
NCT02318303
Study to evaluate the two different strengths and dose regimen of GSP 301 to be effective in treatment of seasonal allergic rhinitis.
NCT00621959
The study objective is to investigate the efficacy of levocetirizine in reducing symptoms associated with seasonal allergic rhinitis and in improving rhinitis-related Quality of Life
NCT00574210
The purpose of this study is to evaluate the relative efficacy of four dosing regimens of bilastine tablets versus placebo in subjects with SAR exposed in controlled ragweed pollen using the EEC model based on the mean change from baseline in Total Nasal Symptom Scores (TNSS). 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.
NCT01651871
The primary objective of the study was to examine the efficacy and safety of S-555739/cetirizine HCl compared with the individual components and placebo.
NCT02155881
The purpose of this study is to explore the efficacy and safety of Ciclesonide Nasal Spray 200 microgram (mcg) once daily in the treatment of seasonal allergic rhinitis (SAR) in Russian participants.
NCT00784732
This study will compare the effectiveness of QAV680 against placebo in treating the symptoms of seasonal allergic rhinitis in an Environmental Exposure Chamber.
NCT00790023
To demonstrate the efficacy of ciclesonide HFA applied as a nasal aerosol (160 μg and 80 μg) once daily compared to placebo in subjects with SAR.
NCT00377728
This study is in patients with seasonal allergic rhinitis(SAR)and will compare the effect versus placebo of repeat doses of intranasal GSK256066 using the Vienna Challenge Chamber. GSK256066 is a potent and highly selective phosphodiesterase-4 (PDE4) inhibitor, currently in development by GSK for the treatment of allergic rhinitis, asthma and COPD. Subjects will be selected on the basis that they display a defined moderate response to the pre-determined dose used. Opportunity to assess the efficacy of compounds versus placebo at maximal and trough plasma concentrations. This study aims to explore the actions of repeat doses of intranasal GSK256066 in patients with Seasonal Allergic Rhinitis in the Vienna Challenge Chamber compared to placebo. 12-lead ECG, vital signs and adverse event enquiries will be made throughout the study. Nasal examination, symptom scores (TNSS), nasal lavage, nasal scrape and allergen challenge assessments will also be performed at various time points throughout the study.
NCT01103934
The objectives of this study would be to see if the addition of vitamin D to fluticasone propionate provides greater symptomatic relief in patients with seasonal allergic rhinitis compared to fluticasone propionate treatment alone.
NCT01983865
This clinical validation study is aimed at establishing a birch pollen challenge in the Fraunhofer ECC in patients allergic to birch pollen. The symptoms will be recorded on a validated symptom score as Total Nasal Symptom Score (TNSS), allowing to determine whether the challenge is dose dependent and reproducible.
NCT00610584
Acupuncture is widely use by patients with seasonal allergic rhinitis (SAR), although there is only limited evidence of its effectiveness. The aim of this three armed randomised controlled multicentre trial is to investigate the efficacy of acupuncture plus rescue medication vs. minimal (sham) acupuncture plus rescue medication vs. (b) rescue medication alone in the treatment of seasonal allergic rhinitis.
NCT00940953
