Resistance to standard of care treatment for stage III unresectable or stage IV melanoma can develop after about 12-15 months. During this period,the treatment will kill the less resistant cells,meaning a tumour has a greater proportion of cells that are resistant to treatment. This study aims to investigate if the patient having breaks in their treatment,guided by the ctDNA TAB level,allows the less resistant cells to continue to grow,resulting in a tumour with a lower proportion of resistant cells,making the ...

Eczema is a common and long-term condition, which affects 20% of children. It is characterised by dry, itchy and inflamed skin. Symptoms tend to come and go, and there are many reasons why a worsening or “flare” of eczema can happen. Many parents wonder whether a food allergy might be a cause, however there is currently no good research evidence to support this. In the TIGER study, we want to find out whether making changes to the diet of ...

The mitral valve is one of four valves in the heart. Its role is to stop blood flowing the wrong way through the heart. Mitral valve regurgitation (known as MR) is a condition where the valve does not close fully when it is supposed to and allows some blood to leak and flow the wrong way. People with MR (valve leakage) may experience dizziness, breathlessness, tiredness and chest pain. If this isn’t treated it can lead to an irregular heartbeat, ...

The Staphylococcus aureus network adaptive platform (SNAP) trial investigates a range of antibiotic treatment options in S. aureus bacteraemia (SAB). Background: S. Aureus bloodstream infection (bacteraemia) is a common,severe global infection. SAB affects ~13000 people/year in England with 15-30% 90-day mortality. Treatment is based on antibiotic susceptibility but we lack evidence to support antibiotic selection with <3000 participants ever recruited into randomised controlled trials (RCT). There are no specific SAB international or UK guidelines. Pragmatic clinical trials are urgently needed,to optimise antibiotic choice ...

The ADVANCE study is post-market, prospective, interventional, global, multicenter, randomized, dual-arm trial. The purpose of the post-market study is to demonstrate clinical benefit with Endurant II/IIs compared to Gore Excluder/Excluder Conformable by generating robust, Level I evidence to elucidate the mechanism of sac regression and any device-related differences, in subjects with Abdominal Aortic Aneurysms (AAA) for whom an EVAR procedure is indicated. Beyond comparing sac regression rates between devices, the study will also investigate if the sac regression led to decreased risk ...

Retinal degeneration has a very significant impact on quality of life. For example, age-related macular degeneration (AMD) is one of the leading causes of vision impairment worldwide. AMD involves progressive damage to the central part of the retina (the tissue at the back of the eye that detects light) called the macula, which is responsible for our central vision and functions such as reading and seeing faces or fine detail. Treatment is currently available for one type of AMD called ...

In coarctation of the aorta, there is a narrowing in the aorta just beyond the branches that supply the head and arms with blood. This prevents the blood from circulating normally in the lower half of the body and can be very serious. The narrowing of the aorta is usually repaired with surgery during early childhood. In the long-term, up to 60% of patients who have had a coarctation repair develop high blood pressure, and this begins in childhood. High blood ...

The FOxTROT platform is a rolling programme of molecularly stratified, randomised phase II/III, multi-centre, international, open-label studies patients with locally advanced but operable colon cancer (CC). FOxTROT 2 is a phase III,multi-centre,open-label,international,randomised-controlled trial of modified dose of OxFp compared to STS,in patients unsuitable for FOLFOXIRI with a left-CC or with a right-CC tumour confirmed to be pMMR or MSS, and not felt to be at risk of bowel obstruction. FOxTROT 3 is a phase III, multi-centre, open-label, international, randomised-controlled trial of 6 ...

This study will look at the safety of curative radiotherapy to the prostate and lymph glands given in 5 visits, in men with high risk localised prostate cancer. The purpose of the research is to test an advanced type of external beam radiotherapy called stereotactic body radiotherapy (also known as SBRT) in 536 participants with high risk localised prostate cancer (that is, prostate cancer that has not spread beyond the prostate gland but is at high risk of growing quickly or ...

Nurses looking after children on intensive care units in the UK aspirate (suck out with a syringe) whatever feed is in the stomach before they decide to give a feed or not. The idea is to check that the stomach is not too full of milk/feed, to prevent the child vomiting, or breathing milk into the lungs. However, there is no evidence to base this practice on. In some countries this practice is rarely done and although recommendation in adult ...
