This trial tests whether using higher (less strict) bilirubin thresholds for starting light therapy in very preterm infants (born before 30 weeks) is as safe as the current Dutch guidelines. About 680 babies across Dutch NICUs will be randomly assigned to one of two threshold str…

This study looks at placing a 3D-printed temporary crown on a dental implant immediately after surgery in the front upper teeth area. Researchers want to see if this approach saves time, helps gums heal better, and makes patients happier with their smile. About 30 adults with a f…

This study compares two types of pacemaker procedures in adults with heart failure and atrial fibrillation who are not candidates for rhythm control. All participants will receive a heart ablation, then be randomly assigned to either conduction system pacing or standard cardiac r…

This study looks at whether an implantable defibrillator (ICD) can reduce the risk of sudden cardiac death in people with non-ischemic dilated cardiomyopathy, a type of heart muscle disease not caused by blocked arteries. Researchers will use MRI scans to find heart scarring (fib…

This study will enroll 40 people with high-risk differentiated thyroid cancer who need radioactive iodine therapy. After stopping their own thyroid hormones, participants will receive either standard levothyroxine alone or levothyroxine plus liothyronine. The goal is to see which…

This study looks at whether reducing the number of kidney function tests during heart failure treatment helps patients reach the best medication doses more safely. About 344 adults with heart failure and reduced ejection fraction will take part. The goal is to improve drug dosing…

This phase 2 trial tests whether combining dapagliflozin (a diabetes drug) with SC0062 (a blood vessel drug) can better protect kidneys in adults with type 1 diabetes and chronic kidney disease. Thirty-six participants will try each treatment alone and together in a cross-over de…

This study tests a weekly injection called survodutide in 120 people with chronic kidney disease and high protein in their urine. The goal is to see if the drug can lower protein levels and protect kidney function over 36 weeks. Participants must be on stable standard treatments …

This study tests whether a fluorescent tracer called WGA-800CW can make precancerous or cancerous cells in Barrett's esophagus glow during endoscopy. The tracer is sprayed onto the esophagus, and special cameras detect the glow. The goal is to find the best dose and see if this m…

This study tests whether a special dye, given before a bronchoscopy, can make lung tumors glow so doctors can see them more clearly. About 20 adults with a suspicious lung nodule or lymph node will receive the dye and then have a bronchoscopy with a special camera. The goal is to…

This study tests a new way to see where an immunotherapy drug goes in the lungs of people with stage III lung cancer. Twenty participants will receive a small dose of a fluorescent version of the drug durvalumab, then have a special camera bronchoscopy to spot the drug in tumors …

This study aims to see if taking PET/CT scans later after injection of a special tracer (18F-Fluoroestradiol) can better detect breast cancer that has spread to the liver or abdomen. Researchers will use a new, more sensitive scanner that allows for later imaging, which may impro…

This study tests how the diabetes drug canagliflozin (Invokana) spreads through the body in 10 dialysis patients with severe kidney disease. Using PET scans, researchers want to see if the drug reaches tissues like the heart and blood vessels, not just the kidneys. The goal is to…

This study follows up with 116 people who got dental implants to support their upper dentures 15 years ago. Researchers will measure bone changes around the implants, check how many implants and dentures are still working, and ask patients how satisfied they are. The goal is to s…

This study looks at 50 adults who get a dental implant and a temporary crown on the same day for a failing front tooth. Researchers want to see how well the implant and crown hold up, how the bone around the implant changes, and how satisfied patients are after at least one year.…

This study tests whether fluorescent dyes attached to two IBD drugs (adalimumab and risankizumab) can show where the drugs go in the gut. 30 adults with ulcerative colitis or Crohn's disease will receive a low dose of the labelled drugs, then undergo a special camera procedure 2-…

This early-phase study tests a new imaging method to see if immunotherapy targets (PD-1 and PD-L1 proteins) are present in esophageal cancer. About 15 participants will receive two fluorescent tracers before a routine endoscopic exam. The goal is to find out if this 'fluorescence…

This pilot study will use brain scans (fMRI) to understand how transcutaneous electrical nerve stimulation (TENS) affects brain activity in 30 people with multiple sclerosis (MS). TENS is a safe, home-use device that sends mild electrical pulses through the skin. The goal is to l…
