Remote ischemic conditioning after aneurysm surgery
This trial tests a safe, non-invasive treatment called remote ischemic conditioning (using a blood pressure cuff on your leg) to see if it helps brain recovery after aneurysm surgery. It might reduce secondary damage and improve outcomes.
Beijing, Beijing MunicipalityAges 18–80 - NCT07299240Recruiting
Arm cuff exercise for better sleep in Parkinson's
This trial tests if a simple, non-invasive arm cuff treatment can improve sleep and other non-motor symptoms in people with early Parkinson's disease. It involves using a blood pressure-like cuff on your arm to briefly restrict blood flow, then release it, hoping to train your body's protective systems.
Nanjing, JiangsuAges 50–70 - NCT05967728Enrolling by invitationPhase 2
Testing remote arm conditioning to protect the brain in stroke
This Phase 2 study tests whether a simple remote method that briefly reduces blood flow in the arm (called ischemic conditioning) can help people with brain small-vessel disease or an acute ischemic stroke. Participants are monitored by phone and, for stroke patients, through a Mobile Stroke Unit.
Calgary, AlbertaAges 55 years+ - NCT05013944Recruiting
Join a patient registry to support future research
This trial is a “patient registry,” which collects health information over time to help researchers plan and run future studies. It may help by contributing your experience so new treatments can be tested more effectively.
Arlington Heights, IllinoisAges 18 years+ - NCT03047369Recruiting
Myelin brain disorder research biobank for samples and data
This study collects brain-related medical information and biological samples to help researchers better understand leukodystrophies and other white-matter brain disorders. It may help future diagnosis and treatments by building a valuable “biobank” of patient data and samples.
Los Angeles, CaliforniaAges Any age - NCT07363980Enrolling by invitation
Heart CT Study for Rheumatoid Arthritis Patients
This study uses a special heart CT scan to look for early signs of heart disease in people with rheumatoid arthritis. It may help find problems before symptoms start.
AarhusAges 50–75 - NCT07678073Recruiting
Comparing Anesthesia Types for Kidney Transplants
This study compares two types of anesthesia (general gas anesthesia vs. a spinal-plus-epidural method) during living-donor kidney transplants to see how they affect certain body signals related to cell health and aging. If you are having a kidney transplant from a living donor and are in good overall health, this trial could help doctors learn which anesthesia may be better for you.
Gaziantep, State/ProvinceAges 18–70 - NCT07250672Recruiting
3D video training for Parkinson's movement
This trial tests if watching personalized 3D videos of movements can help improve walking and other skills in people with Parkinson's. It involves using a special viewer to watch actions that match your own needs.
Bolu, BoluAges 50–85 - NCT01555892RecruitingPhase 1
T-cell treatment for EBV-positive lymphomas
This early-phase study tests a lab-made immune cell treatment (cytotoxic T-lymphocytes) for certain lymphomas and related diseases that test positive for the Epstein-Barr virus (EBV). It may help your immune system attack EBV-infected cancer cells, especially after the cancer has come back or when transplant isn’t suitable.
Houston, TexasAges Any age - NCT07569653RecruitingPhase 4
CMV Prevention After Stem Cell Transplant Using Blood Tests
This trial tests whether doctors can safely stop a CMV prevention medication (letermovir) earlier by using blood tests to check your immune system's strength. CMV is a virus that can become dangerous after stem cell transplant, and this study aims to prevent it while minimizing unnecessary medicine.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07471984Enrolling by invitation
Checking how AI reads brain scans for better diagnosis
This study tests a new AI tool to see if it can help doctors better understand brain MRI and CT scans. It may find issues like strokes, bleeding, tumors, or injuries.
BeijingAges Any age - NCT07258290Recruiting
Freesolve Magnesium Scaffold for Heart Artery Blockages
This trial tests a new dissolvable magnesium scaffold to treat blockages in heart arteries. It is designed for people with stable heart pain or certain recent heart attacks, and it aims to open blocked arteries and then slowly dissolve over time.
Washington D.C., District of ColumbiaAges 18–80 - NCT06227468Recruiting
Mapping immune system genes in Greek adults
This study maps immune system genes (HLA) in Greek adults. It uses a simple cheek swab sample to collect data, with no experimental treatment.
Chaïdári, AtticaAges 18 years+ - NCT05332639Recruiting
Risk tracking test for Crohn’s disease in teens
This study checks whether a personalized tool can estimate someone’s risk for Crohn’s disease before symptoms start. It may help families learn early risk and decide on next steps sooner.
Boston, MassachusettsAges 14 years+ - NCT06859424RecruitingPhase 2
Testing a new GVHD prevention method after donor stem cell transplant
This trial tests a new way to prevent graft-versus-host disease (a common side effect of stem cell transplant) using a drug called cyclophosphamide after transplant. It is for adults with certain blood cancers who need a transplant from a partially matched unrelated donor.
Birmingham, AlabamaAges 18–66 - NCT07595094Recruiting
Blood Age Test for Predicting Health and Disease Risk
This study uses a special blood test to calculate your 'biological age' and predict your risk for serious illness, death, and how long you'll live healthy. Researchers want to understand if this test can help doctors catch health problems early.
Nanchang, JiangxiAges 35 years+ - NCT07491744Enrolling by invitation
Stroke and TIA study on heart and blood vessel health
This study looks at the causes of stroke and TIA by doing extra tests on patients admitted to the hospital. It aims to better understand and prevent future heart and blood vessel problems.

Get help finding the cause of an undiagnosed genetic condition
This study evaluates people whose medical cause is still unclear even after genetic tests and other workups. It uses coded health data and lab samples to look for a new or rare genetic cause, and it may return additional (“secondary”) genetic findings.
Madison, WisconsinAges Up to 100 years - NCT04706481Recruiting
Use of stored, de-identified samples for research
This trial is for people who already agreed to let researchers use their stored biological samples and medical information that has been removed of personal identifiers. It may help future studies by allowing researchers to analyze existing samples without using new samples from you.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,742 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.
