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.
This is a Phase III, randomized, double-blind, placebo-controlled multicenter study to evaluate the efficacy and safety of bevacizumab administered in combination with paclitaxel in patients with previously untreated, locally recurrent, or metastatic HER2-negative breast cancer. Patients will be randomized to one of two treatment arms: bevacizumab or placebo. All patients will be given an intravenous (IV) infusion of of paclitaxel (90 mg/m2) for 3 weeks during each 28-day cycle. bevacizumab or placebo (10 mg/kg) will be administered by IV infusion on Days 1 and 15 of each 28-day cycle. Patients will be treated until disease progression, unacceptable toxicity or death from any cause occurs.
The purpose of this study is to evaluate the efficacy and safety of belimumab, in combination with azathioprine, for the maintenance of remission following a standard induction regimen in patients with Wegener's granulomatosis or microscopic polyangiitis. The random assignment in this study is "1 to 1" which means that participants have an equal chance of receiving belimumab or placebo.
Primary Objective: To compare the effect of alirocumab with placebo on the occurrence of cardiovascular (CV) events (composite endpoint of coronary heart disease (CHD) death, non-fatal myocardial infarction (MI), fatal and non-fatal ischemic stroke, unstable angina (UA) requiring hospitalization) in participants who experienced an acute coronary syndrome (ACS) event 4 to 52 weeks prior to randomization and were treated with evidence-based medical and dietary management of dyslipidemia. Secondary Objectives: - To evaluate the effect of alirocumab on secondary endpoints (any CHD event , major CHD event, any CV event, composite of all cause mortality/non-fatal MI/non-fatal ischemic stroke, CHD deaths, CV deaths, all cause mortality). - To evaluate the safety and tolerability of alirocumab. - To evaluate the effect of alirocumab on lipid parameters.
This prospective, non-randomized, multi-center study is intended to evaluate the Zilver® Vena™ stent in the treatment of symptomatic iliofemoral venous outflow obstruction.
This randomised controlled trial aims to compare the effectiveness of hand reflexology received during office based vein surgery, under local anaesthetic on patient's reports of pain and anxiety, compared to usual standard care.
This randomized, multicenter, double-blind, placebo-controlled study will evaluate the efficacy and safety of onartuzumab (MetMAb) in combination with 5-fluorouracil, folinic Acid, and oxaliplatin (mFOLFOX6) in participants with metastatic human epidermal growth receptor (HER) 2-negative and MET-positive adenocarcinoma of the stomach or gastroesophageal junction. Participants will be randomized in a 1:1 ratio to receive either onartuzumab or placebo in combination with mFOLFOX6. Participants may continue to receive onartuzumab or placebo until disease progression, unacceptable toxicity, participant or physician decision to discontinue treatment.
The objective here is to determine that the efficiency of inhaled drug delivery can be improved by using a fine mist cloud of drug particles (as opposed to a coarse mist cloud of drug particles). This information will be valuable in designing new inhalers in order to improve their beneficial effects and reduce their side effects, by using the least possible drug dose to achieve a good patient response. .
The main objective of this study is to determine whether the first (sentinel) lymph nodes in the drainage pathway of colonic tumour can be detected at the time of surgery using a new technique. The detection method is to inject a fluorescent dye (indocyanine green) adjacent to the tumour. The dye will then be seen as it fluoresces in the light form the near infrared spectrum that can be used at the time of the laparoscopic (keyhole) surgery. An endoscope is placed in the colon (colonoscopy) during surgery and the tracer fluorescent agent is injected around the tumour. The mesentery in which the lymph nodes draining the tumour are located will then be examined by laparoscopy as it is expected that fluorescence will be identified within approximately 5 minutes of the injection. The first lymph node or nodes that take up the fluorescent dye will then be marked by placing a clip or a stitch by them. After the surgery has been completed and colon removed all lymph nodes can be examined microscopically by the pathologist, paying a particular attention to whether any tumour cells are present in the sentinel lymph nodes and whether the presence or the absence of tumour cells in that node accurately reflects the tumour status of the rest of the specimen. If this pilot demonstrates that sentinel lymph nodes can be reliably detected, we have developed a technique which allows us to remove a small area (less than 5 cm) of the colon. Using this procedure should decrease complications following traditional surgery. We however also need a method that allows accurate assessment of the lymph nodes draining the tumour. This pilot trial will examine our ability to detect such 'sentinel' lymph nodes so that we can use their status (positive for cancer cells or negative) to determine whether a smaller operation such as full thickness localised excision is adequate treatment for the patient and that they can avoid a larger operation.
The aim of this randomized, double-blinded, sham-controlled cross-over trial is to demonstrate the effectiveness of continuous transcutaneous electrical stimulation of the pharyngeal dilator muscles to reduce sleep-disordered breathing.
Exposure to particulate air pollution is associated with increases in cardiovascular mortality and morbidity. The pathophysiological mechanisms underlying this observation are emerging, and exposure to particulate air pollution has been shown to result in increases in blood pressure and arterial tone, impaired vascular function and an increased tendency for blood to clot as well as an increase in atherosclerotic plaque burden. Recent evidence from panel studies and controlled exposure studies have suggested an increase in myocardial ischaemia (a reduction in blood flow to the heart) following exposure. In this study we aim to investigate directly myocardial (heart) blood flow following exposure to diesel exhaust (as a model of urban air pollution) using CT/PET myocardial perfusion imaging in male patients with stable coronary disease and healthy male controls. We hypothesize that following exposure to dilute diesel exhaust: 1. Myocardial blood flow will be reduced 2. Coronary flow reserve will be impaired 3. The magnitude of impairment will be higher in patients with coronary disease as compared to healthy controls
