There are about 25228 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.
Researchers are looking for a better way to treat people who have neovascular (wet) age-related macular degeneration (nAMD or wet AMD). In people with wet AMD, the body makes too much of a protein called vascular endothelial growth factor (VEGF). This causes too many blood vessels to grow in the area of sharpest vision in the eye, called macula. Fluid buildup due to leakage from these vessels can damage the macula, leading to vision problems such as blurring or a blind spot in the central (straight ahead) vision needed for reading or face recognition or car driving. Wet AMD is common in people aged 50 and older. The study treatment intravitreal aflibercept (also called BAY865321) is injected into the eye. It works by blocking the VEGF protein and thus reduces blood vessel growth. It has already been approved for patients with wet AMD to be given as intravitreal injection monthly at start and then every 8 weeks or longer. Repeated injections of aflibercept prevent worsening of vision but place a burden on the patient. Doctors try to increase the time between injections (treatment interval) in routine clinical practice based on individual patient needs. This is called treat and extend (T&E). Treatment intervals are stepwise extended or shortened depending on how the treatment works. This is checked with optical coherence tomography (OCT), an imaging technique used to observe relevant changes in the eye. The main purpose of this study is to learn how well aflibercept works if treatment intervals are extended faster (timepoint of extension is the same for both treatments arms), compared to standard T&E regimen in people with wet AMD in a preselected patient population with no fluid after treatment initiation. To answer this, researchers will assess changes in vision called best corrected visual acuity (BCVA) between study start and after 36 weeks. Changes will then be compared between participants whose treatment intervals were extended early and those on standard T&E regimen. All participants will receive 2 mg aflibercept as intravitreal injection for up to 52 weeks in intervals of every 4 to 16 weeks. Each participant will be in the study for up to 56 weeks. During this time 4 visits to the study site are set for all participants. The other visits are set individually. A final phone call is planned 3 days after treatment at the end of study. During the study, the doctors and their study team will: - check patients' eye health using various eye examination techniques (slit lamp microscopy, OCT, and ophthalmoscopy) that may necessitate eye drops to widen the pupil) - measure patients' eye vision (BCVA) - do physical examinations - check vital signs - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. In addition, participants in the fast extension arm will be provided with a home monitoring OCT device.
Endocrine diseases including Cushing's syndrome and phaeochromocytoma/paraganglioma (PPGL) but not Conn's syndrome are associated with muscle wasting and weakness. The study's aim is to identify epigenetic determinants of muscle homeostasis in these conditions following medical treatment and adrenalectomy. This is an observational pilot study that will recruit 66 patients from 3 diagnostic groups: Cushing's syndrome (16), PPGL (20) and Conn's syndrome (30). Indices of muscle bulk and strength will be assessed at diagnosis and at outpatient follow-up 6-9 weeks after adrenalectomy. At these times blood and urine will be collected and a muscle biopsy taken from the operation site at the time of surgery. Pathway analysis in these samples will identify potentially novel signalling pathways contributing to muscle wasting via prolonged exposure to high levels of corticosteroid and catecholamines. This will highlight commonalities and differences in pathogenesis of muscle wasting from a variety of different causes. Finally, it will inform identification of novel therapies for muscle atrophy.
The investigators present a diet intervention study, to be conducted as a within-subject design, with all food and beverages provided, to allow ad libitum feeding to assess impact of diet change on appetite response. The diets will vary in fibre content and type. This study will allow assessment of the physiological impact of dietary fibre on markers of appetite control for body weight, measured from plasma gut hormones. The investigators propose to recruit participants with a poor diet quality (low habitual fibre intake) to additionally examine the time-course of adaptation of the gut microbiome (measured in faecal samples), whilst assessing the impact of added fibre on body weight and subjective appetite scores. This approach is to address the impact of dietary fibre in people living with obesity and food inequalities. The investigators will assess physiological bio-markers of appetite control and their contribution to the development of a gut ecosystem that promotes health. A subsequent period of return to a low fibre feeding will allow assessment of durability of response.
The JUMP (Journey to Understand MMA and PA) Study is being conducted by HemoShear Therapeutics and AllStripes, a rare disease online research platform. JUMP is designed to accelerate understanding of the natural course of methylmalonic acidemia (MMA) and propionic acidemia (PA) disease and treatment for families, researchers, clinicians and industry. The study will collect and provide patient medical record information from multiple institutions for families to access in one place at no cost. AllStripes will remove identifying information like name and address from these medical records and aggregate this data for the HemoShear team to better understand the medical experience and progression of MMA and PA over time. In addition, academic researchers, healthcare practitioners and patient advocacy groups can apply to use the collective patient community data to answer specific research questions at no cost. HemoShear is collecting natural history data on MMA and PA because the company needs insight into the real-world experience of many patients to better understand the disease and be able to scientifically demonstrate whether the potential new treatment they are developing is effective in improving outcomes. This natural history study will include retrospective and prospective components. The retrospective component will consist of data abstracted from primarily electronic health records (eHR) and some paper records. The prospective component will include ongoing collection of medical records from enrolled participants, and participants may opt in to complete health-related questionnaires and an optional genetic testing sub-study. After signing informed consent, participants or their legal guardians will grant permission to AllStripes to collect their health records for data abstraction. Participants may opt into an optional no cost genetic testing sub-study. The JUMP (Journey to Understand MMA and PA) sub-study will help assess whether the genetic variant of the affected person may relate to disease severity and treatment response. Getting genetic testing will enable participants to understand the genetic mutation that causes their type of methylmalonic acidemia (MMA) or propionic acidemia (PA). Knowing the genetic mutations (whether from the MMUT, MMAA or MMAB gene or PCCA or PCCB) can help the impacted person, their caregivers and healthcare professionals understand the potential course of disease and select approaches to better manage the disease. The additional information will enable HemoShear and AllStripes to understand whether different genetic variants impact the disease journey and outcomes. A separate informed consent will be obtained for participating in the sub-study.
The aim of this study is to determine the safety, tolerability and anti-tumoral activity of autologous T cells transduced with a T cell receptor specific for MAGE-A1 in eligible patients with advanced solid tumors.
In this study, researchers will learn more about a study drug called BIIB122 in participants with early-stage Parkinson's disease (PD). The study will focus on participants with a specific genetic variant in their LRRK2 gene. The main question researchers are trying to answer is if taking BIIB122 slows the worsening of PD more than placebo in the early stages of PD. To help answer this question, researchers will use a questionnaire called the Movement Disorder Society-Unified Parkinson's Disease Rating Scale, also known as the MDS-UPDRS. - The MDS-UPDRS measures impairment and disability in people living with PD. It was created in the 1980s and is one of the most used rating scales for PD symptoms. - The MDS-UPDRS has 4 parts, and a higher score means more severe PD symptoms. - Part I assesses non-motor experiences of daily living, including but not limited to memory loss, problems sleeping, pain, depression, and anxiety. - Part II measures motor experiences of daily living. - Part III is the results of a motor symptoms exam by a medical professional. - Part IV records PD complications caused by motor symptoms. Researchers will also learn more about the safety of BIIB122. A description of how the study will be done is given below. - Participants will take BIIB122 or a placebo as tablets by mouth. A placebo looks like the study drug but contains no real medicine. - Participants will be in the study for 103 weeks to 187 weeks. This includes the screening and follow-up periods. - Participants will take BIIB122 or placebo 1 time a day for 96 to 180 weeks. - Participants can continue to take certain medications for PD. Participants must be on the same dose of medication for at least 90 days before the study begins. - Participants will visit the clinic less often as the study continues, ranging every 4 weeks to every 24 weeks.
