Recruiting studies
- NCT05677607Recruiting
Study of brain artery narrowing and small-vessel disease
This study looks at how two types of blood vessel problems in the brain affect each other over time. It may help researchers better understand what to watch for and potentially how to improve outcomes.
Beijing, Beijing MunicipalityAges 30 years+ - NCT05688982Recruiting
Check oral health needs and local care resources in the ER
This study asks people in the emergency department (and their parents/guardians) about oral health needs and what local resources they can access. It aims to map gaps in dental and oral health support so future care can be better targeted.
Boston, MassachusettsAges 1 year+ - NCT05701358Recruiting
Guiding heart stent decisions to fully treat blocked arteries after a heart attack
This trial compares two ways doctors decide which additional blocked heart arteries to treat with stents soon after a heart attack. It may help patients avoid later heart problems by testing a “complete revascularization” strategy planned after the initial culprit artery was treated.
Los Angeles, CaliforniaAges 18 years+ - NCT05723198RecruitingPhase 3
Baricitinib for severe childhood hair loss from alopecia areata
This trial tests whether baricitinib can improve severe alopecia areata (patchy, autoimmune hair loss) in children and teens. It’s meant for people who have had long-lasting, severe hair loss and have tried other treatments without enough benefit.
Birmingham, AlabamaAges 6–17 - NCT05726526Recruiting
Phone app monitoring to help people with advanced kidney disease
This study tests a phone app (with check-ins on things like blood pressure and weight) to help prevent complications in people with advanced chronic kidney disease. You may be a good match if you’re high risk and can actively measure and share your health data with a kidney care team.
Winnipeg, ManitobaAges 18 years+ - NCT05759780Recruiting
Check how an eye probe measures tissue softness
This study uses a special eye/skin/gum imaging test to measure how tissues behave. It may help researchers improve noninvasive ways to understand eye and tissue health, and in some parts of the study, mild keratoconus.
Boston, MassachusettsAges 18–75 - NCT05776641Recruiting
Light and sound training to help prevent Alzheimer’s memory loss
This study tests whether regular “gamma” light and sound stimulation can delay or prevent Alzheimer’s disease-related memory decline in people who are currently not showing dementia but are at higher risk. It uses brain testing (MRI and PET) and memory/language tests over about 13 months.
Boston, MassachusettsAges 55–90 - NCT05788679RecruitingPhase 2
Use a patient’s genetic test to guide treatment after transplant
This study looks at a personalized lab test to detect small amounts of disease after a stem cell transplant and then decide what treatment comes next. It may help some people with certain bone-marrow diseases stay in remission while avoiding unnecessary treatment.
StockholmAges 18 years+ - NCT05870969Recruiting
Digital monitoring to catch liver cancer risk early
This study tests a digital (computer/phone-based) system to help track people with higher risk of liver cancer so cancers can be found earlier. It may help by guiding regular check-ins and making early diagnosis more efficient.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05919485Recruiting
Brain stimulation study for mild cognitive problems in Parkinson’s
This trial tests whether a type of noninvasive brain stimulation (tDCS) can improve thinking and memory in people with mild cognitive impairment in Parkinson’s disease. You may be eligible if you have these diagnoses, are on stable medications, and can safely complete brain scan/testing.
Antalya, AlanyaAges 45–80 - NCT05939999Recruiting
Elastic tape plus rehab for COPD breathing problems
This trial studies whether using elastic tape during pulmonary rehabilitation can improve breathing and physical function in people with moderate to very severe COPD. It may help you tolerate rehab exercises more comfortably if you meet their specific health and safety requirements.
São Paulo, São PauloAges Any age - NCT05962489Recruiting
Sleep-focused DBS therapy study for Parkinson’s disease
This study looks at a sleep-focused approach to brain stimulation (DBS) in people with Parkinson’s disease. You may be able to join if you’re planning or scheduled for specific DBS surgery at the University of Minnesota and have the needed brain imaging.
Minneapolis, MinnesotaAges 21 years+ - NCT05966038Recruiting
Study of ALS and related movement nerve conditions
This study collects and stores medical information from people diagnosed with ALS or certain related conditions affecting movement. It may help researchers better understand how these illnesses change over time and improve future treatments.
Loma Linda, CaliforniaAges 18–90 - NCT06002581Recruiting
Using brain stimulation to slow Parkinson's disease progression
This study tests if a non-invasive brain stimulation technique called rTMS (repetitive Transcranial Magnetic Stimulation) can slow down Parkinson's disease by improving slow-wave sleep. It aims to help people with mild to moderate Parkinson's who are stable on their medication.
Shanghai, Shanghai MunicipalityAges 50–80 - NCT06006819Recruiting
Acute heart failure with chronic kidney disease study
This trial studies how certain markers in the blood can predict outcomes in people with acute heart failure who also have chronic kidney disease. If you qualify, researchers will follow your health during this hospital stay.
Taipei, Baitou DistrictAges 20–90 - NCT06065228Recruiting
Tracking treatment progress in children with IBD
This study looks at a new way to measure how well treatment is working in children with inflammatory bowel disease (IBD). It uses a special eye test called pupillometry, which is painless and non-invasive, to see if it can help doctors adjust treatment earlier.
Washington D.C., District of ColumbiaAges 6–21 - NCT06143332Recruiting
Aerobic exercise after a heart attack: which type works best?
This study compares two types of aerobic exercise (steady vs. interval) to see which one improves heart health more for people who have recently had a heart attack or procedure. If you've completed a stress test and been cleared for exercise, you may be able to join.
London, OntarioAges 18 years+ - NCT06252493Recruiting
PET/MR scan for Crohn's disease scar tissue
This study is testing a new imaging method that uses a special PET/MR scan to see how active Crohn's disease is in your bowel. The scan uses a harmless radioactive tracer that attaches to scar tissue, which may help doctors better understand the disease and guide treatment.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,782 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.
