Filter by:This is a multicenter, randomized, double-blind, placebo-controlled, 2-period, complete block design cross-over study. The purpose of this study is to evaluate the effect of UMEC/VI 62.5/25 microgram (mcg) on EET as measured by the Endurance Shuttle Walk Test (ESWT) compared to placebo. Additionally, the effect of UMEC/VI compared to placebo on lung function and lung volumes in COPD patients will be characterized. Approximately 298 participants will be screened and, assuming 35% of these will not be eligible for randomization; approximately 194 participants will be randomized. Eligible participants will be randomized 1:1 to one of 2 treatment sequences. In sequence 1 participants will receive UMEC/VI 62.5/25 mcg in Treatment Period 1 and placebo in Treatment Period 2. In sequence 2 participants will receive placebo in Treatment Period 1 and UMEC/VI 62.5/25 mcg in Treatment Period 2. Treatments will be delivered once-daily via a dry powder inhaler (DPI). Each treatment period will be for 12 weeks and will be separated by a wash out period of 12-17 days. The total duration of patient participation, including the Follow-Up will be approximately 30 weeks. All participants will be provided with albuterol for use on an "as needed (prn)" basis throughout the run-in, washout and study treatment periods while on investigational product.
The purpose of this study is analyzed the impact of oxygen adjusted during exercise in COPD patients without conventional for LTOT but with exercise desaturation.
The aim of this randomized control study is to determine the feasibility and efficacy of an innovative multidisciplinary telehealth program in chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) patients. 120 patients (1:1) will be included in the study and followed for 4 months and for additional 2 months of follow-up. The primary outcome is to improve tolerance capacity
The objective of the PROGRESS Study is to assess the safety and efficacy of the Propel Mini and Propel Nova steroid-eluting Sinus Implants when placed in the frontal sinus opening following frontal sinus surgery in patients with chronic sinusitis.
The goal of this study is to evaluate how to implement an evidence-based lifestyle-integrated strength and balance exercise (LiFE) intervention in primary care to promote increased physical activity (PA) and improvements in function and quality of life in older adults 75 years or older. This study will evaluate the public health impact of the LiFE intervention using the RE-AIM model: reach (recruitment), effectiveness (PA levels), adoption (physician acceptance), implementation (fidelity), and maintenance (retention, adherence). If the intervention appears feasible, we will use the resultant information to design a larger pragmatic trial.
This national study was a post-marketing surveillance study conducted in Korea from 29 August 2008 to 28 August 2012 to meet local regulatory requirements for Mircera (monopegylated-epoetin beta). Prospective patient-based data collection was evaluated for safety/risk assessments and effectiveness. No specific study-related procedures are required. Patients were to be followed up as long as possible at the physician's discretion.
The study evaluates the effect of GSK2256294 exposure at steady state on pulmonary artery systolic pressure (PASP) in healthy volunteers, under hypoxic conditions, after 7 days of dosing. It is single centre, double blind, randomized, placebo-controlled study to be conducted in approximately 30 healthy volunteers. Subjects will be screened no more than 30 days. Subject will be admitted in clinical unit on Day -1. Subject will be dosed for 7 days in unit in morning on all days except for dosing on Days 3 -6. Dosing on Days 3 -6 will occur at home. Subjects will return to the unit on the evening of Day 6 and remain there until Day 8. Subjects will undergo echocardiography under normoxic and hypoxic on Day 1 pre-dose and on Day 7 post-dose. Subject will be followed up for 28- 32 days after discharge. The maximum estimated time that a subject will be enrolled in the study is 62 days from the screening visit to follow up.
The objective of this study was to compare the bronchodilator efficacy and safety of ipratropium bromide HFA-134a inhalation aerosol and marketed, Atrovent® CFC Inhalation Aerosol in COPD patients
This research project aims to conduct a three-arm multi-center randomized controlled trial (RCT) on an innovative telerehabilitation intervention for patients with chronic obstructive pulmonary disease (COPD). The overall purpose of the RCT is to demonstrate whether long-term integrated telerehabilitation involving exercise training at home, telemonitoring, and education/self-management will prevent hospital readmissions, thus reducing healthcare costs, for patients with COPD, and will improve patient status and quality of life.
Purpose of the study - The purpose of this study is to develop and evaluate the efficacy of a new, theoretically based intervention to improve medication adherence in persons with HF. The hypotheses include: Hypothesis I. Poorly adherent patients with symptomatic HF who receive the intervention (n=40) will be more adherent to medicines during the12-month intervention than a control group (n=40) of poorly adherent patients with symptomatic HF. Hypothesis II. Poorly adherent patients with symptomatic HF who receive the intervention (n=40) will have fewer hospital readmissions (HR) and emergency department (ED) visits during the 12-month intervention than a control group of poorly adherent patients with symptomatic HF. Study Activities and population - A prospective, randomized controlled design will be used to pilot test the efficacy of a new intervention to promote adherence to the medication regimen in chronic heart failure in the clinical setting. The initial development and feasibility testing of the intervention is complete (Preliminary Work, Section 4.5). Patients with HF symptom exacerbation (n = 80) who exhibit high likelihood of poor adherence, as determined by a validated screening measure, the Medication Adherence Scale (MAS)89 at baseline assessment, will be recruited and randomized to receive the intervention or usual care with attention control. Medication adherence, symptom frequency and intensity, hospital readmissions (HR) and emergency department (ED) visits will be assessed in both groups at 3, 6 and 12-month clinic visits. The intervals between visits are considered sufficient to minimize sensitization bias to psychometric measures. Longitudinal measurement is required to evaluate the magnitude of change in adherence and symptom-related events occurring over time. Efficacy will be measured as improved adherence (primary outcome) and decreased HR and ED visits (secondary outcomes) in the intervention group as compared to the attention control group at 12 months. The study will close when all patients have had a 12-month post-enrollment clinic visit. Data Analysis & Safety/Risk Considerations - The investigators will use generalized linear models to test the primary and secondary hypotheses (McCullagh and Nelder, 1989). Logistic generalizations of the traditional, multivariate GLM are appropriate when the dependent variable is binary and the probability of an event is modeled, as is the case with adherence in this study. When the dependent variable is a count, a commonly used generalized model uses the natural logarithm of the count, as with re-hospitalizations and ED visits in this study. In compliance with NIH guidelines for data safety and monitoring activities, a number of quality control steps will be used to ensure the on-going safety of participants and the scientific integrity of this feasibility intervention study. The proposed study poses only very minimal risks to participants. All participants will receive usual care. Participation in the study will not replace patients' regular health care attention. Data safety will be monitored by the PI, the Data Safety Officer (Dr. Karl Swedberg), and the study co-investigators. Any adverse events will be reported immediately to the Duke IRB and the NIH. Data Safety. First, a project database will be constructed, using participant ID numbers and including all demographic, pre- and post-intervention history and all assessment materials. A separate file, cross-referencing participant identification with project ID numbers, will be maintained with access limited to the PI or a designated member of the investigative team.
