Active clinical trials for "Lung Diseases"

This study will evaluate the safety, tolerability, and effect of multiple doses of suvorexant (MK-4305) on respiratory function in participants with chronic obstructive pulmonary disease (COPD). This is a crossover study, so all participants will receive both suvorexant and placebo while on study. The primary hypothesis of this study is that multiple doses of suvorexant do not produce a clinically significant reduction of mean oxygen saturation (SaO2) during total sleep time in participants with COPD, as compared to placebo.

By including in this study patients with significant worsening of their lung volumes and / or their DLCO (carbon monoxide diffusing capacity) in the previous year, on the basis of an open retrospective study we recently conducted, we hope to demonstrate that a strategy combining prednisone and intravenous cyclophosphamide therapy is accompanied by an increase in the frequency stabilization / improvement of lung volumes and / or DLCO of patients at 12 months of 15% in the placebo and prednisone cyclophosphamide 50% in cyclophosphamide and prednisone.We also hope to demonstrate significant decrease in the number of patients excluded for failure in the CYC arm as compared to the placebo arm.

Primary objective: To investigate bronchodilator effect and safety of single doses of BI 1744 CL inhaled via Respimat inhaler, Secondary objective: to characterize pharmacokinetics of BI 1744 CL. Olodaterol dose 40 mcg was investigated only in the open-label extension part for additional PK assessments which are not defined as primary or secondary endpoints.

The study serves to determine whether the treatment of patients with stable, symptomatic Chronic Obstructive Pulmonary Disease (COPD) with the investigational drug NVA237 is efficient and safe. The efficacy and safety of the drug will be tested against a placebo treatment. The primary criterion to assess efficacy will be the difference between the serial lung function measurements of patients who have been treated for 12 weeks with NVA237 versus those that have received placebo treatment for 12 weeks. A serial lung function measurement (FEV1 testing) will be conducted and the "area under the curve" will be the measure for the ability to breathe.

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.

This study compared the efficacy and safety of NVA237 with tiotropium in patients with moderate to severe COPD. Tiotropium belongs to the same drug class as NVA237.

The overall objective of this study is to assess efficacy and safety of 12 weeks, once daily, orally inhaled co-administration of olodaterol 5 µg (delivered by the Respimat® Inhaler) and tiotropium (delivered by the Handihaler® as Spiriva Handihaler®), compared to tiotropium (Spiriva Handihaler®) monotherapy on lung function in patients with COPD.

The improvement in inspiratory muscle function might result in beneficial changes in breathing pattern during whole body exercise. The hypothesis is the effect of inspiratory muscle training as an adjunct to a pulmonary rehabilitation program improves the breathing pattern during an incremental cycle exercise.

Study to demonstrate the comparability of two puffs of Combivent hydrofluoroalkane (HFA) inhalation aerosol (18 mcg ipratropium bromide/100 mcg albuterol sulfate / per puff) to two puffs of the marketed chlorofluorocarbon (CFC) containing product, Combivent (CFC) inhalation aerosol (18 mcg ipratropium bromide/103 mcg albuterol sulfate / per puff). The dose response profile, safety and pharmacokinetics of Combivent HFA formulation are to be characterized.
