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.
Prospective observational study to qualify NM-MRI as progression marker in early Parkinson's.
The primary objectives of this study are to evaluate the safety and tolerability of a switch to Doravirine/Islatravir (DOR/ISL) compared with continued baseline antiretroviral therapy (ART), through Week 48; and to evaluate the antiretroviral activity of a switch to DOR/ISL compared with continued baseline ART at Week 48. The primary hypothesis is that DOR/ISL is non-inferior to continued baseline ART, as assessed by the percentage of participants with HIV-1 ribonucleic acid (RNA) ≥50 copies/mL at Week 48, with a margin of 4 percentage points used to define non-inferiority.
The aim of this first time in human proof of concept (FTiH-PoC) study is to evaluate safety and reactogenicity, to demonstrate efficacy and to explore immunogenicity of GlaxoSmithKline's (GSK) Neisseria gonorrhoeae generalized modules for membrane antigens (GMMA) (NgG) investigational vaccine compared to placebo (saline).
This study is intended to confirm the efficacy, safety, pharmacokinetic (PK) profile, and the durability of hepatitis B virus surface antigen (HBsAg) suppression observed with bepirovirsen for 24 weeks (with loading doses) as compared to the placebo arm. This study will have 4 stages: a) Double-blind treatment (bepirovirsen or placebo) for 24 weeks. b) Nucleos(t)ide analogue (NA) treatment for 24 weeks. c) NA cessation stage OR Continue NA for 24 weeks. d) Durability of response and follow up for further 24 weeks for participants who stopped NA treatment at Week 48. The arms will be stratified based on HBsAg level (HBsAg greater than or equal to [≥] 100 international unit per milliliter [IU/mL] to less than or equal [≤]1000 IU/mL or greater than [>] 1000 IU/mL to ≤3000 IU/mL) at screening. The total duration of the study, including screening (up to 60 days), the double-blind treatment stage (24 weeks), the On NA only stage (24 weeks), and the NA cessation and durability stages (48 weeks) is up to approximately 104 weeks at maximum for each participant.

The primary objectives of this study are to evaluate the antiretroviral activity of a switch to DOR/ISL compared with continued BIC/FTC/TAF at Week 48; and to evaluate the safety and tolerability of a switch to DOR/ISL compared with continued BIC/FTC/TAF, through Week 48. The primary hypotheses are that (1) DOR/ISL is non-inferior to continued BIC/FTC/TAF, as assessed by the percentage of participants with HIV-1 ribonucleic acid (RNA) ≥50 copies/mL at Week 48, with a margin of 4 percentage points used to define non-inferiority; and (2) DOR/ISL is superior to BIC/FTC/TAF, as assessed by the percentage of participants with HIV-1 RNA ≥50 copies/mL at Week 48.
ANCA-associated vasculitis is an autoimmune disease that causes damage to blood vessels. This leads to organ damage with the number of organs affected and the severity of damage varying significantly between patients. Vasculitis patients also have a very high risk of heart attacks and strokes, called cardiovascular disease. A chemical called 'endothelin', produced by the blood vessels, causes vessels to stiffen and raises blood pressure and this associates with cardiovascular risk. The investigators have previously shown that by blocking the effects of endothelin you reduce vessel stiffness, lower blood pressure and improve vessel function. However, these studies only blocked endothelin for a few hours. Now, the investigators would like to see if it is possible to maintain these benefits by blocking endothelin for longer. Sparsentan is a tablet that blocks endothelin and lowers blood pressure. The investigators plan to give sparsentan to patients with vasculitis for 6 weeks. To determine if any beneficial effects of sparsentan are due to blood pressure lowering the investigators will give another group of vasculitis patients a tablet called irbesartan which lowers blood pressure but does not block endothelin. The investigators will compare the results between the two groups.
This cohort study aims to use the open-source RADAR-base mHealth platform to collect and analyze datasets associated with lung disease. This will include continuous data collected from wearable devices (e.g. heart rate, oxygen saturation, respiratory rate), including pulse oximeters, spirometer, mobile phones, digital tests, and smart phone symptom questionnaires.
Patients with lung disease who report breathlessness on exertion are often referred for a 6MWT. Due to the nature of the 6MWT (hereon referred to as a Max-6MWT), patients are required to walk as far as they can in 6 minutes. This may lead to an inaccurate assessment of their requirement for ambulatory oxygen as this form of exercise may not correspond to their normal daily activities. In this study, patients who are routinely referred for a Max-6MWT to investigate possible exercise-induced hypoxaemia will be invited to perform an additional walking test which is performed at their normal walking speed, referred here on in as a Nor_6MWT. We hypothesise that performing a Nor_6MWT will provide a more accurate assessment of a patients' oxygen requirement, primarily from their oxygen desaturation during the test.
The purpose of the study is to find out if iptacopan is effective and safe in adult patients with Paroxysmal Nocturnal Hemoglobinuria (PNH) who switch from their current standard of care treatment (eculizumab or ravulizumab) to study treatment, iptacopan/LNP023.
