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.
It is hypothesized that early changes in the immune system in New Onset Type 1 Diabetes Mellitus (NOT1D) subjects can be detected in immune cells from the inguinal lymph nodes (iLN), which will be distinct from changes observed in peripheral blood derived immune cells. Therefore this study will assess and compare the molecular immune profile of cells derived from the iLN in healthy and NOT1D subjects, to understand the immunological processes that may lead to beta cell destruction. It is a multi-center, non-drug treatment study. Up to 15 subjects in each group, namely healthy subjects and NOT1D subjects, will be evaluated in the study. A data look will be carried out after the recruitment of a cohort of up to 5 healthy subjects, to determine if the quality and quantity of cells derived from aspirate or core biopsy or from peripheral blood are likely to be sufficient to continue the study to meet its primary objective. An interim analysis will be carried out after the recruitment of 5 evaluable healthy subjects and 5 evaluable NOT1D subjects. The primary purpose of this interim analysis will be to facilitate decision making and study design for a potential follow-up interventional study.
Central retinal vein occlusion (CRVO) occurs when the main blood vessel that transports blood away from the retina (the very back portion of the eye) becomes blocked, causing the leakage of fluid into the retina and thereby causing a swelling of the macula (the portion of the retina responsible for fine vision). This swelling is called macular edema. When the macula swells with fluid, central vision becomes blurry. The study drug aflibercept has been shown to reduce the amount of fluid and blood leaked into the retina. It can help to stabilize, and in many cases, improve the vision loss related to CRVO. Aflibercept has been approved for the treatment of macular edema secondary to CRVO in the United States (US), European Union (EU), Japan, and other countries. The study was considered research because, although the study drug was already on the market for macular edema secondary to CRVO, there were no studies available that addressed the questions of what were useful intervals for treating and assessing patients, how did they differ among patients, and how were criteria applied for retreatment. The purpose of this study was to evaluate the effectiveness, treatment interval, and safety of the treatment regimen (pattern for administering treatment) in subjects with macular edema secondary to CRVO. In addition, this study explored new imaging methods for assessing the affected eye.
In England over 800,000 patients each year are either newly diagnosed with depression or present with a new episode of depression in primary care. The majority of patients do not respond to the first drug prescribed and have to try several different antidepressants before an effective treatment is found. Antidepressants have a slow clinical onset of action, taking 4 to 6 weeks before changes in mood become apparent. No test exists to guide General Practitioners (GPs) as to whether their patient is responding to the prescribed successive treatments. This often results in delays of many months before patients return to good mental health. The GP-ETB is a set of computer-based emotional processing tasks. It was developed and optimised to be sensitive to early changes in emotional bias that are indicative of successful antidepressant treatment. The current investigation is an exploratory study using the GP-ETB. It will test the predictive ability of the GP-ETB with regard to later subjective drug response and nonresponse. The study will recruit depressed patients from primary care settings. There are no study drugs prescribed as part of this clinical investigation. Eligible patients will have been prescribed citalopram by their GP prior to study entry. The decision to initiate treatment with citalopram will be independent of study participation. The duration of the study is 5 months. Each patient will be required to attend 3 visits and total duration of the study for the patient will be 46 weeks. During the visits patients will be asked to complete a variety of questionnaires and GP-ETB tasks on the computer. Sensitivity and specificity data collected during this study will be used to develop a computer algorithm intended to predict response at 46 weeks, based on GP-ETB data collected 1 week after initiation of antidepressant treatment.
Metabolic acidosis is a common complication that patients experience in the early postoperative period following cardiac surgery. Increasingly, the composition and volume of intravenous fluids administered during surgery have been implicated in the development of postoperative acidosis. Intraoperative Cell Salvage (ICS), an autologous blood transfusion technique employed by Cardiac/Perfusion Units to minimize blood loss during surgery, involves the infusion of of one such fluid, 0.9% sodium chloride. The rapid infusion of large volumes of 0.9% sodium chloride has previously been linked with the development of hyperchloraemic acidosis. It was therefore hypothesized that the volume of mechanically salvaged of red blood cells re-infused into patients undergoing heart surgery contributes to the acidosis that occurs in the early postoperative period. To test this, the investigators have designed an observational cohort study to check for correlation between the volume of cell salvaged blood infused during surgery and the severity of postoperative acidosis (which will be assessed using data from routine arterial blood gas samples).
The primary objective of this study is to assess the effect of umeclidinium/vilanterol (UMEC/VI) versus tiotropium/olodaterol (TIO/OLO) in subjects with moderated COPD. This is a multicentre, randomized, open label, 2 period crossover complete block design study. Eligible subjects, who complete a 2-week run-in period, will be randomized to receive a sequence consisting of UMEC/VI inhalation powder (62.5/25 microgram [mcg] once-daily [QD]) administered as 1 inhalation via the ELLIPTA® Inhaler and TIO/OLO 5/5 mcg inhalation spray administered as 2 inhalations via the RESPIMAT® inhaler, for 8 weeks each. This will be followed by a 3-week washout period and one-week follow-up period. The total duration of subject participation in the study will be approximately 22 weeks. ELLIPTA is a registered trademark of the GlaxoSmithKline group of companies. RESPIMAT is a registered trademark of Boehringer Ingelheim.
The purpose of the study is to assess the efficacy and safety of BAY1841788 (darolutamide (ODM-201)) in combination with standard androgen deprivation therapy (ADT) and docetaxel in patients with metastatic hormone sensitive prostate cancer.
This prospective case series is to gain additional clinical experience in the treatment of diabetic foot ulcers, by documenting and relating patient history (including baseline wound characteristics) and clinical outcomes (incidence of healing, rate of healing, and patient and physician satisfaction) in a group of study participants for whom the ReGenerCell™ Autologous Cell Harvesting Device (ReGenerCell™) is used in combination with conventional therapy for the closure of diabetic foot ulcers (DFUs). Participants will receive ReGenerCell™ treatment in addition to standard care (debridement, cleansing, dressings, offloading).
The aim of this study is to investigate the cause for the discrepancy in predicted and observed weight loss with Empagliflozin (Jardiance™) by measuring appetite regulation. Major secondary objectives are to determine the effects of Empagliflozin (Jardiance™) on energy expenditure and change in total body weight and body composition. The primary outcome is change in appetite hormone concentrations (specifically total PYY) between baseline and 24 weeks: - this will be measured by sequential blood sampling during visits 1-5. Secondary outcomes, which are exploratory, are effect on appetite hormones (ghrelin and GLP-1), appetite perceptions, total body weight and fat and fat free mass, energy expenditure, appetite perception, physical activity and blood and urine biochemical parameters after Empagliflozin (Jardiance™) treatment for 24 weeks. The sample size for the study is 76 participants and the planned trial duration is 21 months, with participants receiving approximately 24 weeks of exposure to Empagliflozin (Jardiance™).

The purpose of this clinical study is to establish the safety profile, determine the maximum tolerated dose (MTD) and recommend a Phase 2 dose (RP2D) and schedule of SRA737 in combination with low dose gemcitabine; and to evaluate the efficacy of SRA737 in combination with low dose gemcitabine in prospectively-selected subjects with genetically-defined tumors that have predicted sensitivity to Chk1 inhibition based on factors including: genetic profiling of tumor tissue or ctDNA, HPV status, and germline BRCA1 and BRCA2 gene status. Specific cancer indications that frequently feature these factors will be studied. Preclinical and clinical data support the hypothesis that active doses of SRA737 may be strongly potentiated by sub-therapeutic doses of gemcitabine, which should lead to clinical efficacy. To test this hypothesis, SRA737 in combination with low dose gemcitabine is being explored in this study.
