Recruiting studies
- NCT05456503RecruitingPhase 3
PET scan study of tau buildup in memory and brain disorders
This Phase 3 study uses a PET/CT scan to measure whether a brain protein called tau (and related disease patterns) builds up in different dementia conditions. The goal is to better match which disorders have which brain changes and how they progress.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05456893Recruiting
Testing blood and stool markers in active ulcerative colitis treatments
This study checks biomarkers (signals in blood and/or stool) in adults with moderate-to-severe ulcerative colitis. It compares patients starting targeted medicines and looks for marker patterns that may reflect how the disease is behaving.
Nancy, LorraineAges 18 years+ - NCT05460143Recruiting
Optical brain scanning to study memory and thinking
This study uses brain “optical” and possibly MRI scans to understand how thinking and memory work in people with Lewy body dementia, Alzheimer’s disease, or mild memory problems. It may help researchers find better ways to measure brain changes and cognition over time.
CambridgeAges 18 years+ - NCT05461729Recruiting
Testing a heart rehab timing prediction tool after a heart attack
This study follows people with coronary artery disease who are starting a structured heart rehabilitation program after a heart attack or heart procedures. The trial tests whether it can predict and improve the right timing or planning for cardiac rehab.
Ennepetal, North Rhine-WestphaliaAges 18 years+ - NCT05461092RecruitingEarly Phase 1
Nerve blocks to improve pain control after spinal fusion
This early-stage study tests whether a regional nerve block can improve pain control and recovery for older adults having elective lumbar spinal fusion. If you qualify, you may receive a special pain-control injection during surgery to reduce opioid needs and improve recovery comfort.
Iowa City, IowaAges 65 years+ - NCT05462574Recruiting
MRI study of heart fat in pulmonary arterial hypertension
This trial uses MRI (and an additional MRI measurement called MRS) to study fat in the right side of the heart in people with pulmonary arterial hypertension (PAH). It may help researchers understand what’s going on in PAH and how it relates to symptoms and exercise ability.
Nashville, TennesseeAges 18 years+ - NCT05464186Recruiting
Whole versus nonfat milk effects on kids’ body composition
This study compares whole milk vs nonfat milk to see how each affects body composition (such as fat and lean mass) in children. It may help families understand whether milk type makes a difference for healthy growth.
Boston, MassachusettsAges 9–12 - NCT05465252Recruiting
Omega-3 supplement to slow early dry macular degeneration
This trial studies whether taking omega-3 fatty acids can slow the worsening of dry age-related macular degeneration (AMD) in people with early or intermediate disease. It may help by testing if omega-3 changes how the retina changes over time.
ShanghaiAges 50–85 - NCT05466825Recruiting
Using health data to study cardiovascular risk
This study brings together existing health information to understand how common heart-risk factors relate to heart outcomes. It may help improve how future risk is predicted and prevented, especially in people who have not yet had heart disease.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT05468905Recruiting
Study of aging and early thinking changes over time
This study follows adults 40+ to better understand and track changes in memory and thinking as people age. It groups people with normal thinking, subjective complaints, mild cognitive impairment, early Alzheimer’s, and vascular (blood vessel) related brain changes to find what predicts progression.
Hangzhou, ZhejiangAges 40–99 - NCT05469607Recruiting
Tested a device to treat Crohn’s after bowel surgery
This study looks at using a new neurotechnology-based approach (a technology that talks to the nervous system) for people with Crohn’s disease after they’ve had bowel surgery. It’s meant for patients whose new surgical connection (an anastomosis) looks normal on scope and is reachable by colonoscopy.
Melbourne, VictoriaAges 18–80 - NCT05469659RecruitingPhase 2
Test drug to slow kidney damage in type 2 diabetes
This Phase 2 study compares tofogliflozin to metformin to see how well they reduce urine albumin levels (a marker of kidney stress) in people with diabetic kidney disease. You might benefit if your type 2 diabetes is affecting your kidneys despite standard blood-pressure medicines.
Matsumoto, NaganoAges 20 years+ - NCT05470127Recruiting
Testing a new prostate biopsy needle against the usual one
This study compares a new prostate biopsy system/needle with the standard biopsy needle during your scheduled prostate biopsy. It looks at how well the procedure collects tissue for diagnosis and how the tissue samples compare.
Cartersville, GeorgiaAges 18–90 - NCT05470205RecruitingPhase 3
Noninvasive blood-pressure measurement to estimate liver portal pressure
This Phase 3 study tests a noninvasive ultrasound-based method to estimate portal hypertension, which is high blood pressure in the liver’s blood vessels. It aims to help doctors measure how severe the liver circulation problem is without needing invasive pressure testing.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05470335Recruiting
Nurse-led heart procedure setup for suspected heart artery disease
This study checks whether a nurse-led technique for placing a sheath (a small tube used during a heart test/procedure) works safely in people suspected of blocked heart arteries. If you qualify, your care team will guide the process and compare how it goes with standard approaches.
Roskilde, DanmarkAges 18 years+ - NCT05470504RecruitingPhase 2
Pegvisomant for severe insulin resistance from rare fat or gene problems
This Phase 2 study tests pegvisomant, a medicine that blocks growth hormone, to see if it can improve severe insulin resistance in people with a specific genetic cause or a rare fat distribution condition. If you fit the rare diagnosis, the study may help clarify whether growth-hormone blocking can improve blood sugar and related health markers.
Bethesda, MarylandAges 18–70 - NCT05471752Recruiting
Study of special cells taken during orthopedic surgery
This study collects small cell samples from certain body tissues during planned orthopedic surgeries. The researchers will study these cells to understand their potential use in future treatments and to see if using them is safe and helpful.
MilanAges 18 years+ - NCT05473689Recruiting
Sleep study in early spinal cord injury
This study looks at how sleep quality affects movement problems after a new spinal cord injury. Researchers hope to identify sleep targets that could improve motor function during recovery.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,808 recruiting general population (no specific condition or disease) studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a general population (no specific condition or disease) trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a general population (no specific condition or disease) trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
