Filter by:The study will assess the long-term safety of the fixed combination product QVA149 versus placebo and a standard of care treatment (tiotropium) in Chronic Obstructive Pulmonary Disease (COPD) patients with moderate to severe airflow limitation.
The study will be conducted in a respiratory specialist institute in Japan, with standardized techniques and data assurance checks to optimize data quality. The licensed dosage and administration of Adoair in Japan will be applied in this study. Each subject will receive treatment options in a randomized blinded fashion. Subjects will be randomized following a 4-week wash-out phase to take either Adoair 50/250mcg twice daily or placebo twice daily for 12 weeks.
This study assessed the efficacy, safety and tolerability of the co-administration of NVA237 plus indacaterol taken once daily versus indacaterol taken once daily in patients with moderate to severe Chronic Obstructive Pulmonary Disease.
The study is a follow-up of investigations done in the years 1999-2002 in bakery employees. The main purposes are to look at the associations between flour dust exposure and respiratory disease, and to find out the best ways to reduce the flour dust levels in the working environment.
COPD continues to be a cause of major morbidity for patients. Those patients who also have respiratory failure are at higher risk of exacerbations and death and have worse health related quality of life than similar COPD patients without respiratory failure. Treatment options in this group of patients have been limited and data to support the use of machines to assist breathing (non-invasive ventilators) in stable patients are limited. A major limitation of these devices has been patient acceptance and achieving sufficient control of sleep breathing disturbance. Currently devices are set at a fixed pressure to support the breathing throughout the night. The new software within the trial device will aim to better match the support provided by the machine to that needed by the patient. It is hoped that this may offer enhanced comfort as well as superior control of respiratory failure.
The purpose of this study is to create a prospective database of all patients who have undergone pulmonary function testing from which the investigators can study the clinical phenotypes of various respiratory conditions. The investigators hope by understanding the differences in these myriad phenotypes to be able to provide individualized, patient-targeted therapy in the future.
The purpose of this study is to generate a prospective database of all patients evaluated for diffuse parenchymal lung diseases to provide much needed data on the various disease aetiologies, incidence and prevalence rates, clinical and radiological presentations, pathologic correlations, disease progression and response to treatment, and final outcomes in this group of patients in Singapore.
The purpose of this study is to evaluate the clinical utility of specific autoantibody testing in unmasking an underlying connective tissue disorder in patients who present with interstitial lung disease and found to have weak positive ANA (1:400 titre) with no overt connective tissue disease manifestations OR borderline/negative ANA with some clinical suggestion of connective tissue disease.
N-acetylcysteine (NAC) is described as having mucolytic and antioxidant properties. It is widely prescribed for patients with chronic obstructive pulmonary disease (COPD), particularly for those who have accompanying symptoms of chronic cough and sputum production. Randomized, placebo controlled indicate that it is safe and that it may have some clinical benefit when used at relatively low doses. It is postulated that substantially higher doses of NAC will be well-tolerated and will provide better symptom control while also decreasing blood makers of oxidant stress and inflammation.
The main objective of the study is to determine the effects of low-dose oral theophylline added to combination treatment with long-acting β-agonist (LABA) and inhaled corticosteroid (ICS) in patients with severe Chronic Obstructive Pulmonary Disease (COPD) on the rate of exacerbations defined as increase of symptoms that requires a change of medication (antibiotics and/or systemic glucocorticoid) or hospitalisation. DESIGN: Phase III multicenter, randomized, placebo-controlled, double blind, parallel, prospective study. Patient will be recruited during an hospitalisation due to COPD exacerbation and randomised at the time of discharge to receive theophylline 100 mg or placebo on top of combination therapy with inhaled corticosteroids and long-acting beta agonist. The rate of exacerbations will be determined every three months up to one year follow-up. Cl inic visits: every 3 months (total number of clinic visits = 4). In each of them, the following information will be obtained: - Number/severity of exacerbations or hospitalisation since last clinic visit - Compliance and side effects - Blood sample - Plasma levels of theophylline - Sputum (induced) - MMRC - SGRQ - Forced spirometry + inspiratory capacity - At the beginning and at the end of the study - 6MWT - BMI - BODE
