Filter by:The aim of the study is to establish the maximum tolerated dose of PURETHAL Mites that is achieved by 90% of the patients with less than 20% of the injections giving rise to a swelling of > 5 cm and the optimal regimen to reach this maximum dose will be determined.
This is a 6-month multi-center, randomized, double-blind, placebo-controlled, parallel group, efficacy and safety study of ciclesonide HFA nasal aerosol administered once-daily to male and female subjects 12 years or older diagnosed with perennial allergic rhinitis (PAR).
This study will assess the safety and tolerability of multiple doses of VAK694 as well as change in symptoms and biomarkers in patients with seasonal allergic rhinitis
Investigate safety/tolerability after a single dose intranasal administration of DSP-3025 comparator placebo to healthy male volunteers and seasonal allergic rhinitis male patients out of season.
The purpose of this study is to measure the effects of allergens and/or diesel exhaust particles in the nose to learn more about allergic responses in individuals with cat allergic rhinitis.
The investigation will be conducted to define safety and efficacy under the conditions of post-marketing use of this drug in subjects with allergic rhinitis. Post-marketing surveys are not considered applicable clinical trials and thus the results of this survey will not be posted at its conclusion. The results will be submitted to public health officials as required by applicable national and international laws.
Up to 40% of patients with asthma have allergic rhinitis and treatment of nasal airway inflammation with topical steroids improves the twitchiness of the airways (hyperresponsiveness) and overall asthma control. The use of inhaled corticosteroids reduces symptoms, severity of asthma attacks, improves quality of life, and reduces asthma related deaths. Similarly, treatment of rhinitis with nasal steroids reduces symptoms and improves quality of life. While there is evidence that combined treatment of the nose and the lungs with topical steroids improves symptoms and underlying inflammation, it is unclear whether such control can be achieved using a smaller dose of inhaled steroid in combination with nasal steroid. It is therefore the intention of this study to evaluate if combination steroid therapy (nose and lungs) has a steroid sparing effect in patients with asthma and rhinitis using sensitive markers of airway inflammation.
This is a single-centre, randomised, double-blind, four-period, incomplete block, crossover study, with 8 days repeat dosing of intranasal Fluticasone Propionate (25, 50, 100, 200ug) and/or placebo in the Vienna Challenge Chamber in subjects with allergic rhinitis.
The investigators wish to evaluate the effects of decongestants like oxymetazoline and the lessening of this effect with time called 'tolerance'. The investigators will demonstrate a reversal of this tolerance with nasal steroids i.e. the investigators will show that nasal steroids protect against tolerance. This will tell us more on how the investigators can make this treatment effective and safe for patients suffering with allergic rhinitis.
The purpose of this study is to see how a combination spray of azelastine and fluticasone (antihistamine and steroid) compares with a steroid nasal spray (fluticasone) alone in allergic rhinitis i.e. does azelastine permit the use of lesser steroid dose (steroid sparing effect) to achieve the same benefit.
