Filter by:Idiopathic pulmonary fibrosis(IPF) is chronic progressive fibrosing lung disease of unknown cause. There is no effective therapy yet for this disease and the mean survival in most reports is about 3 years after the diagnosis. Because of the stiff fibrosis of the lung, pulmonary hypertension is the late complication of IPF and its development heralds a very poor outcome of the patients. For the primary pulmonary hypertension, recently the effective drugs have been available. However, there is no study about the efficacy of these drugs in the patients with pulmonary hypertension secondary to pulmnary fibrosis, and the aim of this trial is to study the safty and efficacy of "Iloprost," one of the safe and effective drugs in primary pulmonary hypertension.
The purpose of this trial is to evaluate the effects of a single dose of denufosol versus placebo on mucociliary clearance in patients with mild to moderate CF lung disease
BUILD 3 is a prospective, multicenter, randomized, double-blind, parallel group, placebo-controlled, event-driven, group sequential, phase III superiority study. The primary objective is to demonstrate that bosentan delays disease worsening or death in patients with Idiopathic Pulmonary Fibrosis.
The purpose of the study is to identify genetic and biologic markers that may predict the loss of lung function due to idiopathic pulmonary fibrosis. The studies will compare genetic and biologic markers of samples to changes in symptoms. The ultimate goal is to predict if or when patients are likely to experience a rapid decline in lung function due to disease progression.
This study will examine bacteria and toxins in the mouth, lung and digestive system that may be the cause of various diseases or symptoms. H. pylori is a bacterium that produces various toxins that may contribute to lung problems. This study will examine specimens collected from the mouth, teeth, lung, digestive tract and blood to measure H. pylori and its toxins and their effects on cells. People 18 years of age and older with or without gastrointestinal disease may be eligible for this study. These include people without a history of lung disease as well as patients with any of the following: lymphangioleiomyomatosis, asthma, sarcoidosis, other chronic or genetic lung disease (e.g., chronic obstructive pulmonary disease, cystic fibrosis or eosinophilic granuloma). Participants may undergo the following tests: - Blood and urine tests, chest x-ray. - Measurement of arterial blood gases: A small needle is placed in an artery in the forearm to collect arterial blood. - Lung function tests: Subjects breathe deeply and occasionally hold their breath. They may also receive a medication that expands the airways. - Fiberoptic bronchoscopy with lavage and bronchial brushing: The subject's mouth and throat are numbed with lidocaine; a sedative may be given for comfort. A thin flexible tube called a bronchoscope is advanced through the nose or mouth into the lung airways to examine the airways. Saline (salt water) is then injected through the bronchoscope into the air passage and then removed by gentle suction. Next, a small brush is passed through the bronchoscope and an area of the airway is brushed to collect some cells for examination. - Mouth rinsing or teeth brushing to collect cells. - Endoscopy: A small needle and catheter (thin plastic tube) are placed into an arm vein to administer fluids and medications through the vein. A sedative may be given. The throat is numbed with lidocaine and a thin flexible tube called an endoscope is inserted through the mouth and down the esophagus into the stomach and upper part of the small intestine to examine those areas.
Medicines that decrease blood pressure in the lungs may help idiopathic pulmonary fibrosis (IPF) patients function better. This study will test whether sildenafil improves the ability to exercise in patients with pulmonary fibrosis of unknown cause.
The purpose of this trial is to evaluate the safety and effectiveness of a one dose strength of denufosol compared to placebo in patients with mild CF lung disease.
Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease that affects an individual's ability to breathe. Currently, no medications can reverse the damage to the lungs caused by IPF, but individuals are encouraged to engage in moderate exercise to strengthen lung function. This study will evaluate the effectiveness of sildenafil at improving exercise tolerance and breathing difficulties in individuals with IPF.
The purposes of this study are to assess the efficacy of treatment with pirfenidone 2403 milligrams per day compared with placebo in patients with idiopathic pulmonary fibrosis (IPF)and to assess the safety of treatment with pirfenidone 2403 milligrams per day compared with placebo in patients with idiopathic pulmonary fibrosis.
The objectives of this study are to assess the safety and efficacy of treatment with pirfenidone 2403 milligrams per day (mg/d) compared with placebo in patients with idiopathic pulmonary fibrosis (IPF), to assess the safety and efficacy of treatment with pirfenidone 1197 mg/d in patients with idiopathic pulmonary fibrosis and to characterize the pharmacokinetic disposition of pirfenidone in patients with idiopathic pulmonary fibrosis.
