Filter by:This study will last up to 3 years. You will visit the clinic up to 14 times. Certain visits will include lung function tests and scans of your bones. The purpose of this study is to determine the effect of the steroid component of an inhaled product on bone mineral density in patients with Chronic Obstructive Pulmonary Disease (COPD).
This study was designed to test safety aspects and effects on lung function of a new dry powder version of GSK159797 for asthmatic subjects to inhale. This will allow comparison with previous studies which have only used inhalation of the drug as a vapour.
Hypothesis: The reduction of dynamic hyperinflation and its negative effects on the respiratory system following a bronchodilator could lead to an improvement of cardiac function in terms of increased cardiac output. This may enhance oxygen delivery to the exercising muscles in COPD patients. Bronchodilator administration may also have an indirect effect on V'O2 kinetics via its action on cardiovascular and pulmonary variables. Objectives: 1. To evaluate the effects of a bronchodilators on V'E , V'CO2 , and V'O2 kinetics in COPD during constant work-rate cycle exercise, and to evaluate whether bronchodilators will accelerate, indirectly, phase 2 kinetics (usually slower in COPD patients than normal subjects) and shorten t for V'E, V'CO2 , and V'O2 and shorten half-times for HR and O2 pulse, thus showing an improvement of oxygen transport to the peripheral active muscles. 2. To determine the impact of a bronchodilator-induced reduction in dynamic hyperinflation, and its effects on cardiovascular and pulmonary function, on exercise limitation in COPD.
In order to obtain information on a wider range of doses of GW642444 (a possible new medication to treat asthma) than has been previously examined in asthmatic patients, this current study will be conducted at doses of 25 100 and 400 mcg of GW642444 and will be compared with salmeterol (50 mcg twice daily). This study will be conducted in a similar manner to a study that has already been completed (study number B2C101762) which examined repeat doses of 50, 100 and 200 mcg of GW642444. The data obtained will compliment the data from study B2C101762 and will provide confidence (or not) that the desired bronchodilation can be achieved and maintained without undesirable side effects.
This study evaluates the effect of two medicines on COPD (Chronic Obstructive Pulmonary Disease). The study will last 12 weeks. At the end of 12 weeks of treatment, subjects will stop the study medicines for 2 weeks. The study will involve 6 visits to the clinic. Subjects who elect to undergo bronchoalveolar lavage (BAL) procedures will have 8 study visits. Subjects will give sputum, blood, and in some cases BAL samples. Subjects will have breathing tests and will complete diary cards during the study. All study medicines and examinations will be given at no cost to the study subjects. Both medicines used in this study have been approved by the US FDA.
This study is being conducted to see if PRX-08066 can lower pulmonary artery pressures in patients with pulmonary hypertension associated with chronic obstructive pulmonary disease.
This study will examine the effectiveness of a new laboratory method for detecting pneumocystis organisms in a salt-water (saline) oral wash. Pneumocystis infection in people with weakened immunity especially patients with HIV infection or cancer, organ transplant recipients and people receiving immune suppressing therapy can cause life-threatening pneumonia. Currently, pneumocystis infection is diagnosed by sputum analysis or bronchoalveolar lavage. For the sputum analysis, patients are induced to produce a sputum sample (liquid discharge from the lung) using a saline mist; however, many hospitals lack the expertise to perform this procedure. The second method, bronchoalveolar lavage, involves inserting a flexible tube into the lung and injecting saline to produce a specimen for diagnosis. This method, however, is time-consuming and can be uncomfortable. New techniques may allow the use of an oral wash to diagnose pneumocystis, even though an oral sample contains far fewer organisms than are obtained with the current methods. This study will examine whether new techniques, such as nucleic acid amplification, may enable a simple oral wash to be used effectively for diagnosis of pneumocystis infection. Patients 3 years of age and older with weakened immunity who have acute pneumonia may be eligible for this study. In addition, people at increased risk of infection with pneumocystis, including health care professionals, family members of patients, and other patients in health care facilities, may participate. Participants will have a medical history and review of medical records to determine their health status and determine if they have had recent respiratory problems or documented PCP. They will then provide an oral wash sample. For this procedure, subjects first rinse their mouth well. Then, they vigorously swish 50 milliliters of saline for 5 to 10 seconds and immediately repeat the procedure to provide two specimens. Washes may be requested daily, weekly, monthly, or for a period of time to be specified. Participants will also have two tubes of blood drawn (total of 20 milliliters, or 4 teaspoons) to test for evidence of pneumocystis. Although no other tests are required for this protocol, participants may be asked to provide optional add'l samples, as follows: If a sputum or bronchoalveolar lavage sample is required in the course of the patient s clinical mgmt, enough material will be obtained, if possible, for research purposes as well as what is needed for routine care. An induced sputum sample may be requested just for this protocol. For this procedure, a mask with a saline mist is placed over the face, inducing a cough that, it is hoped, will produce sputum from the lungs....
This clinical study is designed to explore dose ranging and identify methods to demonstrate the efficacy of Erdosteine in patients with stable Chronic Bronchitis associated with Chronic Obstructive Pulmonary Disease.
Some patients with chronic obstructive pulmonary disease (COPD) take nebulised treatments to ease the symptom of breathlessness, including the drug ipratropium. Nebulised bronchodilator drugs are taken up to 4 times through the day, and this can take up to 15 minutes each time. Although the treatment isbe effective, patients report that the time taken to set-up and use the nebuliser can be a disincentive to regular use. By contrast, an inhaler device is easy to use following appropriate instruction, and takes only a few seconds to administer. Inhaled tiotropium is a once daily treatment taken by inhaler which has been shown to be effective in COPD. We wish to assess whether inhaled Tiotropium as effective as nebulised ipratropium in patients with stable chronic obstructive pulmonary disease.
Chronic obstructive pulmonary disease (COPD) is a chronic lung disease. Symptoms include shortness of breath, wheezing, and difficulty exercising. Increasing exercise and physical activity may relieve the symptoms of COPD and may also slow the progression of the disease. The purpose of this study is to evaluate the effectiveness of a lifestyle activity program versus a traditional exercise program at increasing the amount of physical activity among individuals with COPD.
