Filter by:The primary objective of this study was to compare the efficacy of intranasal administration of 100, 200, and 400 μg twice daily (bid) of fluticasone propionate, delivered by the Optinose device, with matching placebo in subjects with bilateral nasal polyposis and nasal congestion.
This is an open-label, multicenter study designed to assess the safety of intranasal administration of 400 μg of fluticasone propionate twice a day delivered by the OptiNose device in subjects with chronic sinusitis with or without nasal polyps. The study consists of an up-to-7-day pretreatment phase followed a 3-month open-label treatment phase. The duration of each subject's participation is approximately 13 weeks.
This is an open-label, multicenter study designed to assess the safety of intranasal administration of 400 μg of fluticasone propionate twice a day delivered by the OptiNose device in subjects with chronic sinusitis with or without nasal polyps. The study consists of an up-to-7-day pretreatment phase followed a 12-month open-label treatment phase. The duration of each subject's participation is approximately 53 weeks.
The primary objective of this study is to compare the efficacy of intranasal administration of 100, 200, and 400 μg of fluticasone propionate twice a day delivered by the OptiNose device with placebo in subjects with bilateral nasal polyposis. Two co-primary endpoints will be used in the study: reduction of nasal congestion/obstruction symptoms at the end of Week 4 of the double-blind treatment phase measured by the 7 day average instantaneous AM diary symptom scores, and reduction in total polyp grade (sum of scores from both nasal cavities) over the 16 weeks of the double-blind treatment phase as determined by the Lildholdt scale score measured by nasoendoscopy.
This pilot study is a double-blinded, randomized controlled, two-centre trial in which subjects will receive 4 to 8 (subcutaneous administered) doses of medication (Omalizumab or placebo) (dose and dosing interval calculated on body weight and baseline total serum IgE). During the treatment period and follow-up, the clinical efficacy of the treatment will be assessed by evaluation of symptoms, Quality of Life questionnaire, morning Peak Expiratory Flow measurement, smell test, nasal endoscopy, CT-scan, peak nasal inspiratory flow and spirometry. Biological activity will be evaluated by measuring peripheral and local (in serum, in nasal secretions, biopsies) markers of inflammation. Study hypothesis 1. Evaluation of the efficacy and safety of anti-IgE (Omalizumab) in patients with nasal polyposis and comorbid asthma. 2. Exploration of anti-IgE effects on local and systemic metabolism of IgE in nasal polyposis 3. Clinical assessment of the IgE theory in the pathogenesis of nasal polyps
This study will evaluate the effectiveness and safety of MFNS in improving nasal congestion/obstruction and in reducing bilateral nasal polyps.
A two-part, randomised, double-blind, placebo controlled, multi-centre study to investigate the use of mepolizumab (SB-240563) in reducing the need for surgery in subjects with severe bilateral nasal polyposis.
Nitric oxide (NO) was considered as a mediator of nasal inflammation and the measurement of nasal nitric oxide (nNO) may assist in the diagnosis of nasal inflammation. Few data exists comparing nNO with established, larger accepted reference standard for chronic rhinosinusitis (CRS) diagnosis. Moreover, the role of atopic status on nNO in nasal inflammatory diseases has not been reported. The aim of our study was to determine the value of nNO in patients with chronic nasal inflammation, and to assess the relationship between nNO and atopic status in these patients. A total of 131 randomized patients suffering form chronic nonallergic nasal inflammation and 20 healthy volunteers were finally recruited. nNO was measured by NIOX devices. Sinus computed tomography (CT) scan, nasal endoscope and nasal symptoms evaluation were used in the different diagnosis of chronic rhinitis (CR), CRS without nasal polyps (CRSsNP) and CRS with nasal polyps (CRSwNP). Atopic status was confirmed by skin prick test and serum IgE levels. Blood eosinophils were evaluated simultaneously. Relationships among nNO, various atopic characteristics and chronic nasal inflammation were evaluated.
This is a randomized, double blind, placebo controlled, parallel group, study in patients with chronic rhinosinusitis with or without nasal polyps. The objective is to test the clinical efficacy of long-term low dose oral doxycycline on wound healing quality after endoscopic sinus surgery.
The investigators are doing this research study to learn more about a drug called Xolair (omalizumab). The investigators want to see if it is an effective treatment for chronic rhinosinusitis (CRS). Specifically, the investigators want to see whether Xolair will make nasal polyps smaller and less thick, and relieve symptoms in people with CRS. Polyps are abnormal growths of tissue that can grow in the lining of your sinuses (the inside of your nose). The investigators also want to find out if it is safe to use (whether it causes side effects).
