Recruiting studies
- NCT05242055Recruiting
Tracking and treating chronic kidney disease risk
This trial looks at how well an integrated program for identifying and treating people at risk for chronic kidney disease (CKD) can improve outcomes. It may help by catching problems earlier and guiding treatment sooner.

Test a supplement and track brain changes with wearable sensors
This study tests whether taking nicotinamide riboside (a form of niacin) affects early memory changes in people with mild cognitive impairment (MCI) or mild Alzheimer’s disease (AD). It also uses passive wearable or sensor data (“digital biomarkers”) to measure changes over time.
Belmont, MassachusettsAges 18–89 - NCT05249634RecruitingPhase 2
Testosterone treatment study for men with chronic kidney disease
This Phase 2 study tests whether testosterone therapy can help men with chronic kidney disease who have low testosterone and related symptoms. It looks to see if treatment is safe and beneficial, while carefully checking heart, blood, prostate, and clotting risks.
St Louis, MissouriAges 18–85 - NCT05251415Recruiting
Study of rare autoimmune diseases with blood and medical samples
This trial collects clinical and lab information (like blood and medical history) from people with rare autoimmune diseases, especially when symptoms are unusual. It aims to better understand what causes these illnesses and how newer treatments may help.
ToulouseAges 6–99 - NCT05253560Recruiting
Study prodromal Parkinson signs in GBA1 mutation carriers
This study looks at early (before full disease) Parkinson-like symptoms in people who carry a specific genetic change called GBA1. It may help researchers understand who could develop Parkinson’s and how early signs can be tracked.
Jerusalem, Please Select...Ages 40–75 - NCT05264051Recruiting
MRI scan to predict outcomes in liver disease
This study looks at MRI images taken as part of routine care to see if they can help predict future health problems in people with liver disease. If you already have an MRI scheduled for clinical reasons, this may help doctors better estimate risk over time.
Chicago, IllinoisAges 18 years+ - NCT05266092Recruiting
Study kidney disease immune system activity in dialysis patients
This study looks at how the body’s defense systems (immune system and related signals) behave in people with chronic kidney disease. It may help doctors understand what is driving inflammation and related complications in dialysis patients.
OdenseAges 18 years+ - NCT05268887Recruiting
Light, sound, and touch therapy for Parkinson’s symptoms
This trial tests whether high-frequency light, sound, and gentle touch can improve movement and thinking problems in people with Parkinson’s disease. You may help the researchers learn if this kind of stimulation is safe and beneficial alongside your usual Parkinson’s medications.
Cambridge, MassachusettsAges 45–90 - NCT05287867Recruiting
Study for painful degenerative disc disease treatment
This trial is testing a treatment approach for people with long-lasting, painful worn-out discs in the lower back (and sometimes leg pain). It looks for people who tried common non-surgical options without enough relief and who may be headed toward a lumbar procedure.
Broomfield, ColoradoAges 25–65 - NCT05288842Recruiting
Study spinal fluid and brain changes in dementia types
This study looks at spinal fluid and MRI results in people with Alzheimer’s disease, frontotemporal dementia, or normal thinking (controls). It aims to understand differences in brain-related cells and measure what might help explain or track these conditions.
LilleAges 40–85 - NCT05289167RecruitingPhase 1/Phase 2
Medicines to prevent graft-versus-host disease after a transplant
This trial tests a combination of medicines (post-transplant cyclophosphamide, bortezomib, and abatacept) to lower your chance of developing graft-versus-host disease (when transplanted immune cells attack your body) after a transplant. If you qualify, you’ll receive the study medicines as part of your post-transplant care and be followed closely to check safety and prevention of GvHD.
New Hyde Park, New YorkAges 14–100 - NCT05295615Recruiting
Pulsed magnetic treatment for mild to moderate Alzheimer’s
This trial tests whether a pulsed electromagnetic field (a non-drug device that uses magnetic pulses) can help people with mild to moderate Alzheimer’s. Participants typically stay on stable Alzheimer’s medicines and follow daily home treatments during the study.
Hackensack, New JerseyAges 50–100 - NCT05306834Recruiting
Study to slow memory decline by targeting hidden small brain vessel disease
This trial looks at how to slow cognitive decline and early dementia in people with a specific kind of “silent” blood vessel damage in the brain seen on scans. It may help identify whether targeting this hidden condition can protect thinking and memory over time.
BordeauxAges 60–88 - NCT05307055Recruiting
Testing brain effects after low-frequency stimulation in Parkinson’s
This study looks at how Parkinson’s disease symptoms and brain thinking (neurocognitive function) may change after low-frequency stimulation from an implanted brain device. It may help researchers understand whether this specific stimulation pattern could improve thinking or brain-related symptoms.
Los Angeles, CaliforniaAges 18 years+ - NCT05309343Recruiting
Traditional Chinese medicine study for heart disease patients
This study follows people who are being admitted for heart and blood vessel conditions and records their standard (Western) heart diagnoses. The goal is to describe how traditional Chinese medicine is used for these conditions and what diagnoses the people have.
TianjinAges Any age - NCT05309863Recruiting
Compare home versus clinic weight programs for fatty liver
This study compares two weight-loss programs for children with fatty liver disease related to weight, to see which helps the liver and health better. You may be eligible if your child is already enrolled in a lifestyle program for childhood obesity and meets key safety checks.
Ghent, East-FlandersAges 8–18 - NCT05321758Recruiting
Stool transplant as first treatment for kids with Crohn’s
This study tests whether transferring healthy gut bacteria from stool into the colon can work as a first treatment for children newly diagnosed with mild-to-moderate Crohn’s disease. It may help reduce inflammation and improve symptoms, and it requires regular colonoscopy to monitor progress.
Wuhan, HubeiAges 2–16 - NCT05322343Recruiting
Study biobank and brain health in people age 55–80
This study collects blood samples to build a biobank and learn how brain health changes with age. Some participants may also do an MRI scan to better understand brain changes and immune response.
Bordeaux, BordeauxAges 55–80 - NCT05326750Recruiting
Brain stimulation to help diagnose and manage memory conditions

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,802 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.
