This study looks at how different breathing patterns during strength exercises change eye pressure and blood flow in the retina. Sixty healthy adults aged 18-40 will perform exercises with normal breathing or a breath-holding technique called the Valsalva maneuver. Researchers wi…

This study will test how different intensities and patterns of manual pressure on the upper back affect heart rate, stress hormones, and pain sensitivity in 90 healthy adults. Participants will be randomly assigned to receive either sustained pressure at a single point, kneading …

This Phase 1 trial will test the safety and tolerability of an inhaled drug called SYH2059 in 84 healthy adults. Participants will receive either single or multiple doses of the drug or a placebo. The study aims to understand how the body processes the drug and whether it causes …

This study looks at whether exercising in the morning or evening changes how healthy adults feel pain. 56 participants aged 18-40 will complete pain tests and questionnaires in both morning and evening sessions. The goal is to understand if our body's internal clock affects exerc…

This study tests a new way to take CT scans of the knee while it is bearing weight, like standing. The goal is to see if this method can detect small movements of a knee replacement implant earlier than standard X-rays. The study will include 15 people, some with healthy knees an…

This early-stage study tests whether the experimental drug AZD4916 is safe and how it moves through the body in 160 healthy adults, including Japanese and Chinese volunteers. Participants receive either the drug or a placebo, and researchers monitor for side effects. This study d…

This early-stage study tests a new drug called QL2302 against an approved drug, Tezspire, in 178 healthy adults aged 18-45. The goal is to compare how the body absorbs and processes each drug, check for side effects, and measure immune reactions. Participants receive a single dos…

This early-stage study tests the safety and how the body processes a new drug called NBX-100 in 8 healthy adults aged 21-50. Participants receive four weekly doses and have frequent check-ups and psychological support visits. The goal is to gather safety and drug-level informatio…

This study compares how well people with migraine can imagine movements (motor imagery) versus healthy individuals. Researchers will also check if these imagery skills relate to body awareness, balance, anxiety, and depression. About 136 adults aged 18-65 will participate, using …

This study looks at how the brain uses feedback to control speech in 90 adults aged 18-50, including people who stutter, have dyslexia, and those with typical speech. Participants will do speech tasks, have an MRI scan, and receive mild brain stimulation to see how different brai…

This early-stage study looks at how food and a common stomach-acid drug (rabeprazole) affect the amount of HMPL-760 in the blood. About 24 healthy adults will take the drug under different conditions—fasting, with a high-fat meal, or after rabeprazole. The goal is to learn how th…

This early-stage study is the first time AK0406 is being tested in humans. It will involve 32 healthy adults to check if the drug is safe and how the body processes it. No treatment is being given for any disease—this is purely a safety check.

This study looks at how a special nutritional drink affects blood sugar levels in 30 healthy adults. Participants will drink both the test supplement and a sugar solution on different days to compare the effects. The goal is to measure the drink's glycemic index, which tells us h…
