Online therapy program trial for student depression or anxiety
This trial tests an internet-based therapy program to help students with depression or anxiety. If you qualify, you’ll complete online sessions and assessments to see whether the program helps with symptoms and how long you prefer to use it.
Regina, SaskatchewanAges 18 years+ - NCT05458037Recruiting
Testing fast versus slow numbing during IUD or biopsy
This study compares two ways of applying a numbing tool (“tenaculum”) during an IUD insertion or an endometrial biopsy to see which one causes less pain. If you’re scheduled for one of these procedures, it may help improve how discomfort is managed.
Providence, Rhode IslandAges 18 years+ - NCT05545306Recruiting
Study tests how extra calories change your daily energy use
This study looks at how eating more calories affects your body’s natural heat production and total energy use over a full day. It may help researchers better understand how the body manages weight and energy.
Phoenix, ArizonaAges 18–60 - NCT05574647Recruiting
Fast prostate MRI and guided biopsy testing for prostate cancer
This study checks whether a faster prostate MRI and image-matching (image-fusion) can better find suspicious spots so doctors can target a biopsy. If you have concerning prostate exam results or PSA blood test results, you may get an MRI and, if something looks suspicious, a biopsy using MRI images.
Southend-on-Sea, EssexAges 18 years+ - NCT05674396RecruitingPhase 2
Short-course radiation to ease symptoms from head and neck cancer
This Phase 2 trial tests a specific, shorter type of focused radiation to help relieve symptoms from head and neck squamous cell carcinoma. It compares two radiation timing/planning approaches to see which better improves comfort and quality of life.
Houston, TexasAges 18 years+ - NCT05674643Recruiting
Gastric testing during children’s surgery
This trial studies how the stomach is working in children around the time of surgery. It may help improve how doctors assess and manage stomach function to make surgery safer and more comfortable.
Boston, MassachusettsAges 2–18 - NCT05709600Recruiting
Diet study during planned living kidney donation
This trial looks at whether specific diet changes can be safely used for people who are planning a living kidney transplant. It mainly aims to understand how diet might affect people during the donation/transplant process.
CologneAges 18 years+ - NCT05765162Recruiting
Research study on safer, more tailored anesthesia
This study looks at safer anesthesia—meaning medicines used during procedures—using a more personalized approach. It may help make anesthesia safer for adults having medical procedures.
Nykøbing FalsterAges 18–100 - NCT05799898Recruiting
Fast heart and vessel check for people on immune cancer drugs
This trial looks at a faster heart and blood-vessel assessment for people who are taking immune cancer drugs and have been referred because they might be having a heart-related side effect. It may help by speeding up evaluation and treatment decisions when symptoms raise concern.
ParisAges 18 years+ - NCT05995496Recruiting
Brain changes after eating in women with bulimia
This study looks at how the brain's control over eating changes after a meal, especially in women with bulimia nervosa. You will have an MRI scan and eat a standard meal as part of the research.
New York, New YorkAges 18–45 - NCT06051292Recruiting
Testing balloon size for lung pressure measurement in children
This study tests how much air to put in a small balloon in the esophagus (feeding tube-like device) to measure lung pressure more accurately. It is for children on a breathing machine whose settings are stable for the next 2 hours.
AydinAges 1 month–18 years - NCT06105645Recruiting
Brain wave study for hard-to-treat epilepsy surgery
This study looks at special brain wave patterns called "fast-ripples" to help doctors better plan surgery for epilepsy that doesn't get better with medicine. It may improve how surgeons decide where to operate.
AmiensAges 18–65 - NCT06115148Recruiting
Breath test for malnutrition diagnosis
This study uses a simple breath test to see if it can help diagnose malnutrition. It might help find a quick, painless way to check for malnutrition without needles or scans.
Baton Rouge, LouisianaAges 18–95 - NCT06133231Recruiting
ADHD research with Black and Hispanic families
This study tests if a new approach to ADHD research works well with diverse families. It involves taking supplements and collecting samples at home to see how the body responds.
Portland, OregonAges 6–17 - NCT06219486Recruiting
The safe fast track study for stable patients
This trial tests if stable emergency room patients can be safely monitored without immediate blood tests. It may help reduce waiting times and unnecessary procedures.
Esbjerg, SydAges 18 years+ - NCT06239649Recruiting
Nerve block before knee replacement for faster recovery
This trial tests whether a numbing injection (nerve block) around the knee before surgery can help you recover faster and feel less pain after a total knee replacement. It is for people with knee osteoarthritis who are ready for their first knee replacement surgery.
Denizli, PamukkaleAges 40–85 - NCT06302803Recruiting
Modified intermittent eating for weight loss trial
This trial tests a modified intermittent eating plan to help people with obesity lose weight and keep it off. It compares different eating schedules to see which works best for long-term weight control.
Guangzhou, GuangdongAges 18–75 - NCT06309576Recruiting
Study on body weight regulation using liquid meals
This study tests how the body regulates weight by having participants drink only a special liquid meal for two days. It may help researchers understand weight changes in people with low or high body weight.
Baton Rouge, LouisianaAges 18–40 - NCT06329635Recruiting
Nicardipine via spine tube for brain blood vessel spasm
This trial tests whether giving a medicine called nicardipine through a tube in the spine (intrathecal) helps prevent or treat blood vessel tightening that can happen after a brain aneurysm rupture. It is for people who have had a specific type of brain bleed and show signs of vessel spasm.
Hefei, AnhuiAges 18–80 - NCT06330610Recruiting
Intermittent tube feeding for organ failure in the ICU
This trial tests if giving tube feeding at certain times of day, instead of continuously, helps people on breathing machines recover from organ failure faster. It is for patients who need a breathing tube and are receiving medicine to support their blood pressure.
Rouen, FranceAges 18 years+ - NCT06336902RecruitingPhase 1
Immunotherapy plus fasting diet and vitamin C for KRAS-mutated colorectal cancer
This trial tests a combination of two immunotherapy drugs (botensilimab and balstilimab) plus a fasting-mimicking diet and high-dose vitamin C for people with a specific type of advanced colorectal cancer (KRAS-mutated). It aims to see if this approach can help when standard treatments have stopped working.
Fullerton, CaliforniaAges 18 years+ - NCT06345534Recruiting
