Filter by:The objective of this study is to evaluate the efficacy and safety of specific subcutaneous immunotherapy with modified allergen extracts.
The purpose of this study is to evaluate the efficacy and safety of specific sublingual immunotherapy (SLIT) with allergen extracts in patients suffering from seasonal allergic rhinitis .
This trial is performed to evaluate the safety and clinical efficacy of subcutaneous specific immunotherapy in patients suffering from seasonal allergic rhinitis/rhinoconjunctivitis.
This clinical research study will evaluate the safety and effectiveness of two doses of an investigational medication (ciclesonide nasal aerosol) for the treatment of subjects with of seasonal allergic rhinitis (SAR). The study will consist of a Screening Period to confirm study eligibility, followed by a Single-Blind Placebo Run-in period to acclimate subjects to the proper use of the study medication and to assess the subject's severity of SAR symptoms, followed by a 2-week double-blind treatment period to assess the safety and effectiveness of the study medication when given to eligible subjects.
Levocetirizine (Xyzal®), the active levorotatory enantiomer of cetirizine (Zyrtec®), is a FDA-approved drug used in the treatment of symptoms associated with seasonal and perennial allergic rhinitis and chronic idiopathic urticaria. The parent compound, cetirizine was shown to be effective against experimental dermatographism, however no study has been conducted so far on the effect of levocetirizine on the inhibition of dermatographism. It is known that cetirizine is a mast-cell stabilizer and decreases histamine levels and the number of tryptase positive mast cells. Cetirizine inhibits the production of interleukin 8 (IL8) and leukotriene B4 (LTB4) by immune cells - two potent chemoattractants - and induces the release from monocytes of prostaglandin E2 (PGE2), a suppressor of antigen presentation and MHC class II expression. However, the effects of the most active enantiomer levocetirizine on these inflammatory mediators have not been evaluated so far. Therefore, we aim to conduct a study in humans with dermatographism and chronic idiopathic urticaria to evaluate the effect of levocetirizine on the above-mentioned mediators. The study will involve the use of skin microdialysis, a minimally invasive technique to measure inflammatory mediators in the extracellular space in dermis.
Objectives: A) To gather pharmacodynamic measurements and assess blood levels of the active ingredients in AHIST over the dosage interval period of 12 hours. Hypothesis: Hysteresis curves plotting each active ingredient's blood levels over a 12-hour dosage interval will substantiate S5 Symptom Diary scores (IE: evidentiary therapeutic window data); B) To report subjective scores by subjects rating the efficacy of a single dose AHIST in relieving nasal congestion, rhinorrhea, nasal itching, sneezing, and post-nasal drip over a 12-hour dosage interval. Hypothesis: Greater than 66% of subjects will document clinically significant relief over a 12-hour period from one dose of AHIST; C) Report any side effects or adverse drug reactions and rate the severity of any incidence. Hypothesis: Not more than one patient will have an adverse event significant enough to warrant withdrawal; side effects will be mild with the most frequently reported side effect occurring in less than 10% of patients—drowsiness.
The objective of the current study is to investigate the efficacy, safety and tolerability of BI 671800 ED using three dose levels of BI 671800 ED (50 mg, 200 mg and 400 mg), administered twice daily compared to FP (fluticasone propionate) nasal 100 mcg per nostril qd in the morning or Montelukast 10 mg qd am given for 2 weeks in patients with SAR (seasonal allergic rhinitis) out of season using an environmental exposure chamber in patients known to be sensitive to the aero-allergen Dactylis glomerata.
Non-interventional, open-label, single group, multicentric post-marketing surveillance to monitor the safety and effectiveness of AVAMYS nasal spray administered in Korean patients according to the prescribing information. AVAMYS is a registered trademark of the GSK group of companies.
The hypothesis is that treating hay fever patients who had daytime sleepiness and slowed thinking because of the hay fever will improve when treated with an effective anti-hay fever medication, an intranasal steroid, that is will have less daytime sleepiness and demonstrate better thinking.
Subjects with perennial allergic rhinitis will be randomized to 320 mcg of beclomethasone dipropionate (BDP) using a hydrofluoroalkane (HFA) propellant or placebo as a nasal aerosol. The subjects will be followed for safety and efficacy for a period of 30 or 52 weeks. BDP HFA is a steroid which is currently FDA approved for the treatment of asthma. BDP-HFA should be safe and effective as a "dry" nasal aerosol which may be preferred by some patients.
