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.
Part 1 of the study evaluates the safety and tolerability as well as pharmacokinetic properties of a single oral dose of BOS172767 enantiomer E1 and BOS172767 enantiomer E2 following administration to healthy participants. Part 2 of the study was to be conducted to assess the safety and tolerability as well as pharmacokinetic properties of one selected enantiomer (BOS172767-Ex) following multiple ascending doses over 14 days of dosing in healthy participants.
The purpose of this study is to assess the efficacy of seltorexant compared with quetiapine extended-release (XR) as adjunctive therapy to an antidepressant drug in treatment response in participants with major depressive disorder with insomnia symptoms (MDDIS) who have had an inadequate response to current antidepressant therapy with a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).
The goal of this trial is to find out whether taking semaglutide tablets at different times before and after eating has a similar effect compared to the recommended dosing time. Participants with type 2 diabetes are recommended to take semaglutide on an empty stomach, and they should not eat, drink, or take any oral medicine for at least 30 minutes after that. The trial will look at how different dosing times of semaglutide before and after eating a meal changes how much semaglutide participants get into their blood. Participants will get one semaglutide tablet daily for a total of 10 days. For the first 5 days participants will receive semaglutide tablets of 3 mg and for the next 5 days, participants will receive semaglutide tablets of 7 mg. From here onwards, semaglutide tablets will be referred to as the 'trial medicine', unless specifically mentioned. Participants will get the trial medicine (3 mg and 7 mg) under one of the 5 following dosing conditions. It will be decided by chance under which dosing condition participants will receive the trial medicine: A 2 hour fast before taking the trial medicine and 30 minutes fast after taking the trial medicine (Test arm A), A 4 hour fast before taking the trial medicine and 30 minutes fast after taking the trial medicine (Test arm B), A 6 hour fast before taking the trial medicine and 30 minutes fast after taking the trial medicine (Test arm C), A 2 hour fast before taking the trial medicine and an overnight fast (at least 6 hours fast) after taking the trial medicine (Test arm D), An overnight fast before taking the trial medicine and 30 minutes fast after taking the trial medicine (Reference arm E). Before each fasting period prior to receiving the trial medicine, participants will fast for 4 hours and then receive a standardised meal. The meal should be completed before the 2, 4 or 6 hours fasting is started. The trial will last for about 48 to 78 days (about 1.5 to 2.5 months). Participants will have 4 scheduled visits with the study doctor. At one of the visits, participants will be admitted to the trial unit and have to stay for 12 consecutive days. At all visits participants will meet with trial staff and will have blood tests along with other clinical checks and tests. Participants will be asked about their health, medical history, and habits. Women only: Women cannot take part if pregnant, breast-feeding, or planning to become pregnant during the trial period.
There is a degree of uncertainty regarding the role of perioperative chemotherapy (CTx) in the treatment of resectable colorectal liver metastases (CRLM). In the clinical practice, the combination of surgery and CTx is increasingly accepted as treatment for CRLM, especially in the context of patients with synchronous disease or metachronous disease with a high risk of recurrence. However, controversy exists whether all patients with resectable CRLM benefit from perioperative CTx. There is paucity of good quality studies on this topic. A pooled analysis of two phase III randomized clinical trial, closed prematurely because of slow accrual, showed a marginal statistical significance in favor of adjuvant CTx. Nevertheless, long term results of the EPOC trial founded benefit in disease free survival (DFS) with no difference in overall survival (OS) when perioperative CTx with FOLFOX4 was compared with surgery alone for resectable CRLM. Furthermore, a retrospective series from Ayez et al showed that patients with a high CRS benefit from neo-adjuvant CTx while in patients with a low risk profile did not. On the other side, another retrospective series from the MSKCC showed the timing of additional CTx for resectable CRLM was not associated with improved outcomes. The ongoing CHARISMA trial is currently comparing the outcomes of neo-adjuvant CTx followed by surgery versus surgery alone in high-risk patients with resectable CRLM. This uncertainty regarding CRLM management may partly be due to the fact that these studies are not well powered to detect minor differences in long term outcomes and they often involved a very heterogenous group of patients with both synchronous and metachronous CRLM, not stratified by clinical risk score (CRS) as described by Fong et al.
The disease leishmaniasis mainly occurs in hot and tropical countries, affects millions of people and causes around 20,000 deaths across the world every year. Leishmaniasis is caused by the Leishmania parasite and is transmitted by sand flies. The parasite is tiny and not visible to the naked eye, whereas the sand fly is visible but small and inconspicuous. There are different types of leishmaniasis which can affect the skin (cutaneous leishmaniasis) or the internal organs of the body (visceral leishmaniasis). Some of the milder forms will produce skin problems which will be localised, whilst other forms of leishmaniasis will cause widespread skin changes. The skin lesions of cutaneous leishmaniasis can be disfiguring if left untreated. There are some treatments for leishmaniasis but many of them are not easy to use or don't work well. Therefore, new treatments are needed including vaccines that prevent or work against leishmaniasis. A solution being adopted for other diseases, which the investigators now wish to adopt for leishmaniasis is to develop a 'Controlled human infection model' (CHIM). These models involve deliberate exposure of individuals to an infection, in order to better understand how the disease works and to test potential vaccines and treatments. They have contributed knowledge that has led to advances in the development of treatments. This is study builds on an our initial successful study, FLYBITE, where uninfected (disease-free) sand flies were used to test the safety aspects and ensure that sand flies were able to bite human participants in a controlled environment. The investigators observed no major adverse effects and it was well tolerated by participants. The investigators therefore wish to proceed to a study using sand flies infected with a form of leishmaniasis that causes localised skin disease and is treatable, on the pathway to assessing future vaccines.
Single-blind within subject comparison study conducted to investigate the skin protectant properties of Omeza Collagen Matrix on damaged skin
The purpose of this study is to assess whether computer aided technology (CAD) can help in the diagnosis of polyps found the bowel compared with visual inspection alone and therefore whether it is beneficial in helping clinicians to decide whether to remove a polyp or not. Presently, most endoscopists remove all polyps found and send them to the laboratory for testing. The number of colonoscopies is increasing, meaning that more polyps are detected and removed. This comes at a significant cost to the health service and increases the time taken to complete a colonoscopy.
To determine the effects of amino acids on the rate of water absorption and availability as a precursor fluid for sweat. Young and healthy (male or female) volunteers will take part in three experimental trials. In each trial, volunteers will be given one of two commercially available sports drinks or a commercially available sport drink with added amino acids in a double-blinded, randomised, crossover design. Each drink will be a single 550 mL bolus. All beverages will be labelled with deuterium (D2O). Trials will be compared for temporal accumulation of deuterium in plasma over the course of 60 minutes and in urine (60 min). Whole blood measurements of haemoglobin and haematocrit will also be made and plasma volume changes calculated. It is hypothesised that the amino acid trial will increase the rate of fluid absorption.
Microvascular angina (MVA) is caused by abnormalities of the small blood vessels in the heart. Endothelin-1 (ET-1) is a chemical messenger that circulates and accumulates in the blood vessel walls, causing them to narrow or go into spasm and thicken over a long period, especially as levels of ET-1 increase. As a result, patients experience pain, psychological distress and limitation of their daily activities. Cambridge is a participating recruitment site for a large randomised, double blinded, placebo controlled crossover trial (the PRIZE study: NCT04097314) investigating Zibotentan as a new drug treatment for patients with MVA using a 'precision medicine' approach. Zibotentan is a drug originally developed by Astra Zeneca for prostate cancer but prior research has shown that it acts to relax the small blood vessels of patients with MVA, highlighting its potential as a novel therapy for this patient group. The PRIZE study population will be enriched for 'responders' to the drug by screening patients with MVA for a gene mutation known to increase levels of circulating endothelin. The trial aims to initially invite approximately 356 participants for genetic testing but only 100 participants will go forward into the main study, with approximately 2/3rd being screen failures. In our sub-study, we will invite patients with MVA who are screen failures at our site for further blood tests looking for other genetic variants in the ET-1 signalling pathway and examine how this correlates with the severity of microvascular angina quantified by cardiac MRI and clinical assessments. Data from this sub-study would provide a bio-resource for further analysis of the main PRIZE trial to identify other patients that would benefit from Zibotentan.
