There are about 25435 clinical studies being (or have been) conducted in United Kingdom. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to evaluate the safety and efficacy of the addition of veliparib plus carboplatin and paclitaxel versus the addition of placebo plus carboplatin and paclitaxel in adults with advanced or metastatic squamous non-small cell lung cancer (NSCLC).
A major determinant of perioperative mortality is the inability of the heart to increase its output in response to surgical stress. This is termed perioperative cardiac failure (PCF), and may only be apparent postoperatively when oxygen demand is increased. The risk of perioperative cardiac complications is the summation of the individual patient's risk and cardiac stress related to the surgical procedure1. The functional capacity of the patient determines their ability to support the postoperative demand of increased oxygen consumption, and therefore of cardiac output. Exercise capacity is one of the most powerful predictors of cardiovascular and all cause mortality2. Cardiopulmonary exercise test (CPET) is an established investigation used, among other applications, in the preoperative assessment of patient fitness for surgery3. CPET involves monitoring the electrocardiographic trace and the exhaled gas mixture (particularly CO2, whose production depends on aerobic metabolism), during incremental exercise (usually on an exercise bike), on room air. Several parameters can be measured during CPET, including maximal systemic oxygen delivery, the anaerobic threshold (the oxygen delivery value at which anaerobic metabolism begins), maximum workload, and ST segment depression/elevation (as in a standard exercise tolerance test). The cardiopulmonary "performance" during CPET has been correlated with postoperative outcome3. Pulmonary function tests will be performed in order to assess lung function. It is well known that therapy with beta-blockers in patients with ischaemic heart disease and cardiac failure reduces perioperative morbidity and mortality4-7. However, beta blockers reduce myocardial contractility and the heart rate response to adrenergic stimulation, thus blunting the physiological response to stress/surgery/exercise. Whilst this mechanism may protect the heart perioperatively, it may decrease the ability of some patients to withstand other complications. This potential decrease in "performance" has never been quantified. There is no agreement on whether preoperative CPET should be performed on or off beta-blockers and, at Aintree in particular, it is standard procedure to take patients off beta-blockers prior to their CPET. Some argue that, as beta-blockade should be maintained in the perioperative period, CPET should be performed on medications, even if these could mask the presence significant ischaemic heart disease (a significant, modifiable, risk factor for surgery by beta blockade), and even if it is not always possible to maintain beta-blockade throughout the whole postoperative period. For these reasons, other clinicians prefer to perform CPET off beta-blockers, thus, potentially, overestimating the perioperative cardiorespiratory "performance", which may be diminished once the medications are resumed. Patients on long-term beta blockade may develop some tolerance to the medications, so the effect of acute and chronic beta blockade on cardiorespiratory performance may also be different. Aim To compare cardiopulmonary performances on and off beta blockers as objectively assessed by cardiopulmonary exercise testing.
Cryotherapy has a long history of safe use in various medical procedures. RejuvenAir System radial spray cryotherapy is a novel procedure being developed as a treatment for conditions associated with abnormal bronchial function, such as chronic bronchitis. The development of appropriate reliable equipment, definition of therapeutic parameters, and an understanding of the tissue effects of treatment have been established through animal studies. This clinical study is being undertaken to assess the feasibility and safety of the application of a radial metered dose spray cryotherapy in the human airway and to evaluate the treatment depth in human airways. The study design is prospective, open label, single arm multi-center study that will consist of up to 15 subjects at up to 3 enrolling sites in Ireland, UK and The Netherlands RejuvenAir System treatment will be performed during preoperative bronchoscopy 0 to 60 days prior to prescheduled lung resection in Subjects requiring lobectomy or pneumonectomy for removal of peripheral tumors. Treatment will be limited to areas of the bronchi within the lobe that will be removed, distal to the anticipated margin of resection. Treatment should be at least 1 cm from the bronchial resection margins and away from the tumor bed. Treated airways will be inspected via bronchoscopy at the time of thoracotomy, and examined histologically following surgical resection. Subject participation will be from 1 to 60 days and enrollment is anticipated to take 4-5 months.Total study duration is expected to last approximately 10 months.
The purpose of this study is to record and compare the inhalation profiles of non pregnant women and those who are in the third stage of labour. The inhalation profiles will be recorded from consenting women as they inhale with maximal effort through an inhalation profile recorder [Glaxosmithkline (GSK), Ware]. The recorder will simulate resistance to airflow and will be representative of a dry powder inhaler of moderate resistivity. The inhalation endpoints will include Peak Pressure Drop, Peak Inspiratory Flow Rate, Inhaled Volume, Inhalation time, Average Inhalation Flow Rate and Acceleration rate which will be compared between the two female cohorts. Inhalation profiles recorded in this way may subsequently be used to study the in-vitro performance of investigational materials across inhalation parameters representative of the target patient population. An appropriate number of subjects will be consented so that approximately 40 subjects (20 non-pregnant females and 20 stage three labour subjects) complete assessments. The inhalation profiles will be recorded on the same day of screening or at another time within a span of 50 days
This is a multi-centered, randomized, placebo-controlled, double-blind, parallel group, trial evaluating 2 doses of mepolizumab against placebo given every 4 weeks through subcutaneous (SC) injection. In severe COPD subjects, sputum eosinophils levels are elevated to similar levels as those seen in severe asthmatics. It is hypothesized that the reduction of eosinophils with mepolizumab in COPD subjects would translate into a reduction of COPD exacerbations. The study will evaluate the efficacy and safety of mepolizumab, in subjects who are at or above the baseline blood eosinophil count of at least 150 cells/microliters who exacerbate despite regular use of maximal tolerated therapy, appropriate for severe COPD subjects, in the 12 months prior to study start. In total, 660 subjects will be randomized in 1:1:1 ratio to receive mepolizumab 300 mg, mepolizumab 100mg, or placebo administered SC. The total duration of subject participation will be approximately 62 weeks, consisting of a 1 to 2 week screening period, 52-week treatment period and 8-week follow-up period.

This is a prospective, non-randomized, study of the safety and efficacy of the Occlutech® LAA occluder indicated for percutaneous LAA closure in adult male or female patients with atrial fibrillation. Safety and efficacy will be assessed at day 1, 30 and 90, and after 1 year following implantation of an Occlutech® LAA Occluder.
Aim: To evaluate the feasibility and safety of a restrictive versus liberal red blood cell (RBC) transfusion policy in adult patients admitted with Acute Upper Gastrointestinal Bleeding (AUGIB) in order to inform the design of a definitive phase III randomised controlled trial.
Accu-Chek® Insight Insulin Pump EU Study is a Multicenter Study to evaluate the Accu-Chek® Insight Insulin Pump in routine practice. This is an open-label, prospective, multinational, multicenter study evaluating the CSII therapy with the Accu-Chek Insight Insulin pump in routine practice in adult subjects with Type 1 or type 2 diabetes. Subjects must have been on intensive insulin therapy for at least six months i.e. either on CSII or MDI. All subjects will receive training in the preparation, programming and daily use of the Accu-Chek Insight Insulin pump. In addition, subjects previously on MDI may receive more training in order to be comfortable with the use of an insulin pump. The study will be conducted in 10-12 sites in Austria, France and the United Kingdom. A total of 80-95 subjects will be enrolled in this study.
