Filter by:After a nasal allergen challenge it should be possible to measure markers of inflammation that may be useful to assess the properties of future drugs. If these markers are reproducible and impacted by the study drugs they could be useful for future drug development.
A single and multiple dose study to assess the safety of JNJ 38224342 compared to placebo in healthy volunteers and in volunteers with seasonal allergies.
This study compared the efficacy and safety of a generic mometasone nasal spray to the reference listed drug in the treatment of seasonal allergic rhinitis. Additionally both the test and the reference formulations were tested for superiority against a placebo nasal spray.
The purpose of the study is to assess the efficacy and safety of an investigational nasal aerosol compared with placebo nasal aerosol in the treatment of seasonal allergic rhinitis.
The purpose of the study is to determine whether VAK694 when combined with subcutaneous immunotherapy leads to long term immune tolerance to allergen in individuals with seasonal allergic rhinitis.
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.
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.
People who have hayfever or allergic rhinitis often complain about eye symptoms associated with their nasal symptoms. How people with hayfever develop eye symptoms is not clear. The purpose of this study is to better understand the generation of eye symptoms in patients with allergic rhinitis. We have previously shown that placing the substance that subjects are allergic to in their nose causes both nose and eye symptoms. This can be explain by a parasympathetic neurogenic reflex from the nose to the eye. Such a reflex would readily explain the tearing and watery eye symptoms, but does not explain the itch. In this study, we are going to address one possible explanation for the itch; does an axonal neurogenic reflex stimulate mast cells in the eye to release histamine, which then causes the itch? We will do this by placing an antihistamine drop in the eye and challenge the nose with allergen. We will also attempt to demonstrate that mast activation isn't effected by blocking the initiating of the reflex with a nasal steroid, as done in our previous study, and showing that the addition of an antihistamine does not add to the reduction of symptoms.
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.
