Rochester, MinnesotaAges 4 years+ - NCT05170412Recruiting
Diet habits study for adults with sickle cell disease
This study asks adults with sickle cell disease about what they eat and their eating routines. The goal is to understand diet patterns in sickle cell and how they may relate to health, which could help future care and guidance.
Bethesda, MarylandAges 18–120 - NCT05182892Recruiting
Reducing speech side effects from DBS using speech recordings
This study tests whether automated analysis of your speech can help reduce speech problems caused by deep brain stimulation (DBS) in Parkinson’s disease. It may help your team adjust DBS settings to improve how you speak while keeping Parkinson symptoms controlled.
PragueAges 18 years+ - NCT05183074Recruiting
MRI-guided focused radiation for prostate cancer
This trial tests a newer way to plan and deliver radiation for prostate cancer using real-time MRI guidance. It may help by aiming high-dose treatment precisely while treating nearby disease and (in some cases) limited metastatic spots.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05185609Recruiting
Tests anal function in people with inflammatory bowel disease
This study checks how well the anal area works in people with inflammatory bowel disease (IBD), even when your bowel disease is “in remission” but you may still have symptoms. It may help doctors better understand the cause of ongoing problems and guide future care.
ÖrebroAges 18–65 - NCT05188885Recruiting
Chronic kidney disease registry for real-world care
This study collects health information from people with chronic kidney disease (CKD) and also from some people without CKD but with kidney risk factors. It helps doctors understand how CKD develops and how it’s managed in everyday life, not to test a new drug.
Foshan, GuangdongAges 18 years+ - NCT05192057RecruitingPhase 4
Inhaling salty steam for lung MAC infection
This trial studies whether inhaling hypertonic (very salty) saline helps treat nodular-bronchiectatic lung disease caused by Mycobacterium avium complex (MAC). It may help reduce ongoing infection and symptoms if you have the right type of MAC lung pattern and have not recently started the usual MAC treatments.
NijmegenAges 18 years+ - NCT05193162Recruiting
Study of gut microbes using stored pancreatic tissue
This study looks at differences in microbes (tiny organisms) using previously collected pancreatic tissue samples. It may help doctors understand how the microbiome relates to pancreatic diseases like pancreatic cancer.
ShanghaiAges 5–85 - NCT05194787Recruiting
Online tests to spot early Alzheimer’s changes
This study looks at whether online motor (movement) and thinking tasks can detect early changes related to Alzheimer’s disease. You may be able to take part if you’re over 50 and do not already have a diagnosis of dementia.
Hobart, TasmaniaAges 50 years+ - NCT05205980Recruiting
Training practice to help prevent falls in Alzheimer’s
This trial tests whether a specific “training practice” can reduce falls in people with probable Alzheimer’s disease. It may help by improving safe walking and balance after doing the training.
Valdosta, GeorgiaAges 65–90 - NCT05204459Recruiting
MRI and eye-scan study for MS and related conditions
This trial uses brain MRI and eye imaging tests to study research markers in people with multiple sclerosis (MS) and related neurologic conditions. It may help researchers better understand these diseases and how they change over time.
Los Angeles, CaliforniaAges 18 years+ - NCT05208567Recruiting
Testing heart ultrasound in older adults with weak heart pumping
This trial uses a heart ultrasound test to find people who may have weak heart pumping function, especially in a multi-ethnic community. It may help improve how doctors detect this condition earlier using ultrasound images.
LondonAges 65 years+ - NCT05210764Recruiting
EEG brain activity changes during pediatric surgery under anesthesia
This study looks at how the brain’s electrical activity (measured with a painless EEG sensor) changes in children during planned surgery using common anesthesia medicines. It may help doctors better understand brain effects of anesthesia in healthy children having non–head or non–heart surgery.
BeijingAges 1 minute–18 years - NCT05216042Recruiting
Study of genetics and heart/metabolic health in adults
This study looks at how genetic markers (DNA) relate to heart health and “metabolic” health (how your body manages sugar and fat). You may be asked to provide genetic samples and follow study health checks and protocols to help researchers understand who is at higher risk.
Birmingham, AlabamaAges 18 years+ - NCT05224193Recruiting
Study of exercise and sleep in kids with inflammatory bowel disease
This study looks at how physical activity and sleep habits affect children and teens with inflammatory bowel disease. It may help doctors understand which routines could support better day-to-day health and disease management.
Southampton, HampshireAges 6–18 - NCT05231798RecruitingPhase 2
PET and brain scans in adults with Down syndrome
This study looks at how well a brain chemical system works in adults with Down syndrome as they age, including how it relates to Alzheimer’s-type brain changes and thinking skills. It uses brain scans and memory/thinking tests to see whether these measures can help track risk or changes over time.
Nashville, TennesseeAges 18–55 - NCT05231876Recruiting
French Wilson disease registry
This study keeps a registry (a confidential list) of people with Wilson disease. It helps researchers learn more about the disease and improve future care, without requiring specific treatment changes.
Paris, Île-de-France RegionAges birth–99 years - NCT05232240Recruiting
Study blood pressure swings after stroke or TIA
This trial studies changes (“swings”) in blood pressure in people who recently had an ischemic stroke or a TIA. It may help doctors understand how blood pressure fluctuations affect recovery, even when you do not have known hypertension.
Beijing, BJAges 18 years+ - NCT05236374Recruiting
Daily beef in a heart-healthy diet to study zinc cells
This study tests whether eating daily beef as part of a heart-healthy diet changes how your body’s cells handle zinc, a mineral important for many functions. It’s designed for older adults and includes strict diet and medication rules to keep results accurate.

International registry for people with Wilson’s disease
This trial is a patient registry that collects health information from people with Wilson’s disease, including those without symptoms yet and those taking any type of treatment. It helps researchers understand the disease and how it progresses, which can support future studies and care improvements.
LeuvenAges 12 years+ - NCT05241418Recruiting
MRI study of heart scar using gadolinium in repaired heart defects
This trial looks at heart MRI images to see whether a contrast dye (gadolinium) can highlight scar-like areas after congenital heart problems have been repaired. It may help doctors better understand healing and plan care, especially for future heart procedures.

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.
