Filter by:This will be a randomized, double-blind, placebo-controlled, parallel-group, multicenter study. After passing the initial Screening Visit, subjects will be in the environmental exposure chamber(EEC), a room with a controlled amount of ragweed pollen, for 4 hours each day on 4 consecutive days. At the last visit, subjects who have achieved a minimum Total Nasal Symptom Score (TNSS) will be randomized to receive either TOLAMBA or placebo treatments. Subjects will receive 6 weekly subcutaneous (under the skin) injections of the study drug. About three weeks after the last injection, subjects will be asked to be in the EEC for 2 consecutive days (Visits 11 and 12, Days 60 and 61). Approximately 3 weeks after Visit 12 (Day 61), the subjects will again be in the EEC for 4 consecutive days (Visits 13-16, Days 82-85). During all EEC visits, the subjects will be exposed to ragweed pollen at an average concentration of 3500 ± 500 pollen grains per cubic meter. Each EEC visit will last 4 hours. During each EEC visit, patients will be asked to record symptom scores for nasal and non-nasal symptoms at scheduled time points. The total duration of a subject's participation in this study is expected to be a minimum of 85 days.
The purpose of this study is to evaluate how well mometasone furoate nasal spray (MFNS) works to relieve SAR symptoms compared to Placebo when symptoms are induced in a chamber setting. Evaluation will be based on subjects self-assessed nose symptoms. Other areas the study will evaluate are: 1) changes in eye symptoms (ocular symptom severity score) after dosing 2) how long MFNS works in relieving the nose (nasal) and eye (ocular) symptoms after 7 daily doses, 3) measurements of nose (nasal) blockage (obstruction), and 4) measurements of the subject's opinion of the study drugs by asking different questions. This study is could last up to 53 days for some subjects.
Study objective is to verify the superiority of CTZ DS to the placebo groups in the change of total nasal symptom score (TNSS) over the total treatment period from the score of the baseline assessment period.
The investigators wish to evaluate the onset of tolerance to nasal decongestants like oxymetazoline (available over the counter) and the mechanism of tolerance particularly with differential effects on alpha 1 and alpha 2 adrenoreceptors on the nose. The investigators will 'tease' out by using an alpha 1 blocker called Prazosin. The investigators hypothesize that alpha 1 receptors mediate arterial constriction and this will be captured by measuring nasal blood flow. The investigators also hypothesize that alpha 2 receptors mediate venous sinusoid constriction and this the investigators will capture by airflow parameters like Peak Nasal Inspiratory Flow, Rhinomanometry, Oscillometric indices etc.
We hypothesize that specifically selected probiotics can alleviate symptoms of allergy in lactose tolerant individuals. Two strains of probiotics, Lactobacillus rhamnosus GR-1, and Bifidobacterium adolescentis 7007-05 will be used to create a yogurt product. Additionally a non-probiotic yogurt product will also be made as a placebo. Allergy sufferers will be asked to consume one of the two types of yogurts (blinded) for two months. During the two months there will be 3 sampling days, for blood samples and nasal lavage samples. Additionally Mini Rhinoconjunctivitis Quality of Life Questionnaires will be filled out weekly over the two months. After the two months of perceived responses as well sample analysis we should have a better idea of how these specific probiotic effect the immune system and allergies.
This study is designed to assess the effectiveness of mometasone furoate nasal spray (MFNS) once daily compared with placebo in subjects with seasonal allergic rhinitis (SAR) in reducing the total symptom score.
This current study is planned as a dedicated pharmacodynamic (effect of drug on the body) study to investigate the dose response in rhinitic subjects at doses where GSK256066 has been proven to work (200mcg) or expected to (50mcg) work. This study also aims to investigate the lower end of the predicted therapeutic range.
The purpose of this study is to compare the systemic des-ciclesonide exposure of OMNARIS™ (ciclesonide) nasal spray, ciclesonide HFA nasal aerosol, and orally inhaled ciclesonide HFA-metered-dose inhaler (MDI). The administration of the study medication will be as follows: three single doses, separated by a wash-out period. The study will provide further data on the safety and tolerability of ciclesonide.
This study is designed to assess the effectiveness of mometasone furoate nasal spay (MFNS) once daily (QD) compared with placebo in subjects with seasonal allergic rhinitis (SAR) in reducing the total nasal symptom score and the total ocular symptom score.
The clinical study evaluates the efficacy and safety of MK0476 in adult patients with allergic rhinitis.
