PragueAges 18 years+ - NCT06846034Recruiting
How low oxygen affects kidney blood flow
This study tests how low oxygen levels affect blood flow in the kidneys. It includes healthy people, people with type 2 diabetes, and those with diabetes plus kidney disease to see if their kidneys respond differently.
PoitiersAges 18–75 - NCT06918184Recruiting
Exercise timing after breast cancer surgery
This study tests whether starting specific physical therapy exercises early or later after breast cancer surgery is better for recovery. It may help women who are at risk for arm and shoulder problems after surgery.
CairoAges 18–65 - NCT05576818RecruitingPhase 3
Synbiotic add-on for people with Parkinson’s disease
This trial tests whether adding a synbiotic (a mix of probiotics and prebiotics) along with standard Parkinson’s medicines can improve symptoms or health outcomes. It’s mainly for adults with Parkinson’s disease at earlier to mid-stages who take dopamine replacement therapy.
Tanta, El GharbiaAges 45–65 - NCT06573762Recruiting
Home monitoring for Parkinson's disease
This study uses a Fitbit to track movement and symptoms from home. It is for people who are newly referred or recently diagnosed with Parkinson's disease.
Iowa City, IowaAges 50–110 - NCT06776965Recruiting
Ultra-processed foods and rheumatic disease study
This study explores how eating ultra-processed foods affects people with chronic rheumatic diseases like rheumatoid arthritis, spondyloarthritis, or osteoarthritis. It aims to understand if diet plays a role in symptom management.
LyonAges 18 years+ - NCT06923709RecruitingPhase 2
Amiloride for slowing kidney disease progression
This trial tests if the drug amiloride can help slow down chronic kidney disease. It may be an option if you have moderate kidney function and high protein in your urine.
OdenseAges 18 years+ - NCT06924580Recruiting
ECG to predict multi-system disease outcomes
This study collects ECG and diagnosis information from hospital patients to see if early ECG readings can predict multi-system diseases. It aims to create a follow-up database to improve future care.
Shanghai, Shanghai MunicipalityAges Any age - NCT07208344RecruitingEarly Phase 1
Umbilical cord blood infusion for Alzheimer's disease
This early-phase study tests whether infusing donated umbilical cord blood (a source of young immune cells) can help slow Alzheimer's disease. It is for people aged 50–75 with mild to moderate Alzheimer's who have a caregiver and are otherwise generally healthy.
Hefei, AnhuiAges 50–75 - NCT06925594RecruitingPhase 3
Cell injection for Crohn's-related anal fistulas
This trial tests a new cell injection (TH-SC01) to treat anal fistulas caused by Crohn's disease. It aims to see if the injection can heal fistulas and lower infection risk.
Nanjing, JiangsuAges 18–70 - NCT07203404RecruitingEarly Phase 1
A study of a universal CAR-T cell therapy for autoimmune diseases
This trial tests a new treatment called RD06-05, which uses specially engineered immune cells to target and potentially reset parts of the immune system that are attacking your own body. It is being studied for several autoimmune conditions like lupus, vasculitis, kidney diseases, and more.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07207122Recruiting
Focused ultrasound for Parkinson's cognitive symptoms
This trial tests whether a non-invasive ultrasound treatment, called transcranial focused ultrasound stimulation (tFUS), can improve movement and thinking in people with Parkinson's disease. It may be an option for those whose symptoms are not well controlled by medication alone.
Tucson, ArizonaAges 22–80 - NCT07205289RecruitingPhase 1
Blood sample study for vaccine test development
This study collects blood samples to help researchers develop better tests. It is for healthy people who have not had a pneumococcal vaccine before.
Adelaide, South AustraliaAges 18–69 - NCT07208058RecruitingPhase 3
Testing plonmarlimab for blood cell overactivation in people with rheumatic disease
This trial tests a new drug called plonmarlimab for people with a rheumatic (joint or immune) disease who also have a dangerous overreaction of their immune system called HLH (or MAS). The goal is to see if the drug can help when high-dose steroids have not worked or are not an option.
Beijing, Beijing MunicipalityAges 16–80 - NCT06925178Recruiting
Imaging database study for recent stroke patients
This study is building a standard imaging database for people who have recently had a stroke. By participating, you will help doctors better understand how to use different types of scans to diagnose and treat cerebrovascular disease.
Beijing, Beijing MunicipalityAges 18–80 - NCT07205003Recruiting
Artery stiffness test for memory disorders
This study looks at how the stiffness of your carotid artery (the main artery in your neck) relates to memory problems. It involves a brain MRI that you may already have planned, and results could help doctors better understand certain types of dementia.
RouenAges 70 years+ - NCT07207057RecruitingPhase 3
Platform trial testing multiple drugs for Parkinson's disease
This trial tests several experimental drugs at once to find new treatments for Parkinson's disease. If you have Parkinson's and take medication, you may be able to join and help speed up research.
LondonAges 30 years+ - NCT07206095Recruiting
Better diagnosis for inherited red blood cell diseases
This trial aims to improve how doctors diagnose rare inherited anemias, including sickle cell disease and other conditions that destroy red blood cells. It may help if you have a confirmed or suspected diagnosis but need more clarity through advanced testing.
Barcelona, BarcelonaAges Any age - NCT06232772Recruiting
Biomarkers for early Parkinson's diagnosis
This study looks for new markers in the blood or other samples to help diagnose Parkinson's disease earlier. It compares people with Parkinson's, related conditions (like multiple system atrophy or progressive supranuclear palsy), and healthy volunteers to find differences.

- Yes. Clin2 currently lists 10,619 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.
