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 randomized, active controlled, multicenter phase III open-label study is designed to evaluate the efficacy and safety of alectinib compared with crizotinib treatment in participants with treatment-naive anaplastic lymphoma kinase-positive (ALK-positive) advanced non-small cell lung cancer (NSCLC). Participants will be randomized in a 1:1 ratio to receive either alectinib, 600 milligrams (mg) orally twice daily (BID), or crizotinib, 250 mg orally BID. Participants will receive treatment until disease progression, unacceptable toxicity, withdrawal of consent, or death. The study is expected to last approximately 144 months.
Heart imaging with magnetic resonance imaging (MRI) provides detailed insights into heart function and injury. The nature and significance of heart injury after a heart attack is incompletely understood. We propose a 'natural history' study of heart attack injury using contemporary MRI methods. In a large hospital in the West of Scotland, heart attack patients will be invited to have at least two MRI scans and also continue with life-long follow-up. The results from the MRI scans will be assessed with all of the other clinical information obtained at the time of the heart attack and during follow-up. The results of our study should provide new insights into heart attack injury and these results should help improve how heart attack patients should be treated.
Patients diagnosed with low risk non-muscle invasive bladder cancer (NMIBC) are at risk of frequent low grade recurrence, which usually necessitates surgical intervention under general anaesthetic. This multicentre study aims to establish the short term efficacy of chemoresection using chemotherapy within the bladder for the treatment of NMIBC. Should the levels of complete response following chemoresection meet predefined criteria, a larger phase III trial would be developed to assess longer term disease related endpoints, with the aim of standardising management of recurrent low risk NMIBC and potentially removing the need for over a thousand patients each year to undergo surgery.
The study PNET 5 MB has been designed for children with medulloblastoma of standard risk (according to the risk-group definitions which have been used so far; e.g. in PNET 4). With the advent of biological parameters for stratification into clinical medulloblastoma trials, the ß-catenin status will be the only criterion according to which study patients will be assigned to either treatment arm PNET 5 MB - LR or to PNET 5 MB - SR, respectively. The initial diagnostic assessments (imaging, staging, histology, and tumor biology) required for study entry are the same for both treatment arms. With the amendment for version 12 of the protocol, patients who have a WNT-activated medulloblastoma with clinically high-risk features can be included in the PNET 5 MB WNT-HR study, and patients with a high-risk SHH medulloblastoma with TP53 mutation (both somatic or germline including mosaicism) can be included in the PNET5 MB SHH-TP53 study. Data on patients with pathogenic germline alteration or cancer predisposition syndrome, who cannot be included in any prospective trial due to unavailability or due to physician or family decision, can be documented within the observational PNET 5 MB registry.
Children on conventional haemodialysis (HD) die of heart disease. Also, they can be malnourished and short. Haemodiafiltration (HDF) is a newer type of dialysis that achieves better removal of toxins and excess fluid than HD. On HDF, adults have a longer survival and children show improved growth, but mechanisms are not understood. We will follow children in the UK and Europe to compare HDF and HD. We will monitor growth, heart and blood vessel scans, blood markers and quality of life. If the 3H (HDF-Hearts-Height) study shows reduced cardiovascular morbidity and better growth, HDF may be adopted as the preferred type of dialysis in children.
Autoimmune diseases are diseases in which inappropriate immune responses that have the capability of harming host cells play an important role. Evidence suggests that the presence of certain autoimmune diseases such as rheumatoid arthritis or systematic lupus erythematosus increase the risk of cardiovascular disease (CVD). However, this evidence is inconsistent for autoimmune disorders and no systematic approach has been previously used to study the relationship between a range of common autoimmune disorders and specific forms of cardiovascular diseases such as myocardial infarction, intracerebral and subarachnoid haemorrhage, or venous thrombosis. The investigators will use linked electronic health records to investigate whether commonly diagnosed autoimmune disorders are associated with increased risk of CVD development and whether effects differ in men and women and change with age.
This is a randomised, phase II open-labelled two-arm study comparing R-GEM-P and LR-GEM in second-line treatment of Diffuse Large B-cell lymphoma. Eligible patients will be randomised 1:1 between R-GEM-P and LR-GEM.
New effective non-surgical treatments are needed for patients whose obesity and type 2 diabetes (T2DM) do not respond to current medical therapies. We propose a randomised controlled trial of Endobarrier, an implantable intestinal device that separates ingested food from contacting the first 60cm of intestine where sited and that mimics some of the clinical effects of bariatric surgery (improved metabolic control with weight loss) with or without continued use of the GLP-1 receptor agonist (GLP-1RA) Liraglutide 1.2mg vs Liraglutide 1.8mg without the device in obese patients with T2DM who remain with suboptimal glycaemic control despite current conventional diabetes treatment, in an NHS setting. Seventy-two patients with T2DM and obesity (HbA1c≥7.5%, BMI≥35kg/m2) despite previous GLP-1RA therapy will be studied over 24 months and randomised to receive Endobarrier with continued Liraglutide 1.2mg for 12 months; Endobarrier alone for 12 months; or Liraglutide 1.8mg without Endobarrier. We will investigate potential mechanisms of action and their time course as part of the study by repeated measures of: 1. insulin resistance measures, gut peptides, bile acids; 2. energy intake and nutritional composition; 3. liver fat stores, 4. intestinal inflammation and permeability measures. The data will inform clinical use of the device and development of new treatments for T2DM and obesity.
Narrowing of coronary arteries interferes with blood flow and can cause chest pain. But patients may have more than one narrowing and studies have shown that not all narrowings need to be treated. To identify the narrowings that need treating cardiologists sometimes quantify the extent of the narrowing by measuring fractional flow reserve (FFR, the ratio of the pressure in the aorta to the pressure downstream of the narrowing).This technique requires the administration of drugs that add cost and time to the procedure and in some countries are simply unavailable. As a result despite the clear health and healthcare costs benefits of FFR its use is limited to less than 5% of procedure. We have developed a new technique called the instantaneous wave-free ratio (iFR) that does not require the administration of drugs for its accurate assessment. It has been approved for use in this indication. This study aims to compare clinical outcomes of patients whose treatment has been guided by iFR to those whose treatment has been guided by FFR. If iFR is found to provide the same clinical outcomes as FFR its adoption will permit the clear benefits of this approach of identifying the coronary narrowings that really need treatment to be applicable to a much larger patient population and further improve healthcare costs.
Despite the fact that the majority of the patients with limited disease SCLC will respond very well to the standard treatment, a great proportion will relapse within 12 - 24 months. Several studies in patients with lung cancer suggested a possible favourable association between the increased presence of immunologically active cells in the tumour and survival. Nivolumab and ipilimumab are proteins, which help your immune system to attack and destroy cancer cells by your immune cells. Early clinical trials with nivolumab and ipilimumab have shown activity in a broad range of cancers, including SCLC. The aim of the current study is to investigate the efficacy (how well the treatment works) and tolerability (how severe the side effects are) of the standard treatment (chemotherapy and radiotherapy) alone, compared with the standard treatment followed by nivolumab and ipilimumab in patients with limited SCLC.
