Recruiting studies
- NCT00196742Recruiting
Fabry disease registry and pregnancy follow-up
This study collects health information from people with Fabry disease and specifically from pregnant people with Fabry disease. It helps researchers better understand the condition and how pregnancy affects health, using information you already experience in routine care.

Kidney disease in children study that follows patients over time
This is a long-term study that watches children and young adults with chronic kidney disease to understand how the illness changes and to improve care. You may be asked to complete regular visits and questionnaires, and your kidney function will be tracked over time.
Kansas City, MissouriAges 6 months–22 years - NCT00567073Recruiting
Register pregnant people with Pompe disease for pregnancy data
This study keeps a special record of pregnancies in people with Pompe disease to learn more about pregnancy outcomes and newborn information. It does not test a drug by itself—it collects health information to improve future care.
Phoenix, ArizonaAges Any age - NCT01752738Recruiting
Study of gut microbial metabolites in chronic kidney disease
This trial studies how substances made by gut microbes travel in people with chronic kidney disease. You may be asked to have a planned colonoscopy so researchers can measure intestinal samples and better understand kidney disease.
Leuven, Vlaams BrabantAges 18–85 - NCT00692939RecruitingPhase 1/Phase 2
Stem cell transplant for people with Crohn’s who need new options
This trial studies whether an “autologous” stem cell transplant (using your own cells) can improve Crohn’s disease that has not responded to standard treatments. It may help people who have ongoing, hard-to-control Crohn’s even after medicines and/or who have complications that make surgery risky.
Pittsburgh, PennsylvaniaAges 10–60 - NCT00842283Recruiting
Study of how new blood vessels affect skin diseases
This study looks at how new blood vessel growth may be involved in skin conditions. It may help researchers learn whether blocking this process could become a future treatment, and you may contribute by having a skin biopsy.
Irvine, CaliforniaAges 16 years+ - NCT01245179RecruitingPhase 1
Panobinostat for adults with severe sickle cell
This early-phase study tests panobinostat, a medicine aimed at reducing sickle-cell problems, in adults with severe disease. It’s mainly looking at safety and whether it can improve blood-related issues that drive pain and complications.
Augusta, GeorgiaAges 18 years+ - NCT01904851Recruiting
Registry for leg artery procedures and their outcomes
This study collects information about people who had a procedure to improve blood flow in certain leg arteries. It helps researchers understand which treatments work best and what outcomes to expect.
Little Rock, ArkansasAges Any age - NCT01351545Recruiting
Cryopreserved cord blood access program for transplant patients
This trial studies an organized way to obtain and distribute unlicensed (not FDA-approved for general use) stored cord blood units that have been frozen and kept. It may help people who need a cord blood transplant but don’t fit the “licensed cord blood only” options.
Birmingham, AlabamaAges Any age - NCT01574053Recruiting
Global Huntington’s disease registry for gene carriers and controls
This study builds a global record of people who carry the Huntington’s (HD) gene change and people who do not. By comparing them over time, researchers hope to better understand how HD begins and progresses.
Birmingham, AlabamaAges 18 years+ - NCT01653223Recruiting
Simvastatin to protect the heart during heart surgery
This trial looks at whether simvastatin (a cholesterol medicine) can help protect the heart during cardiac surgery. You might be invited if you’re having surgery for certain, non-complex heart conditions, but not if you have some specific related health problems.
Guangzhou, GuangdongAges 18 years+ - NCT02435810Recruiting
Study of infections and inflammation affecting the nervous system
This study looks at how infections or inflammation involving the brain and spinal cord work, using patient data and samples. It may help researchers better understand these illnesses and improve future care.
Bethesda, MarylandAges 2–110 - NCT02852928Recruiting
ChILD-EU registry for childhood lung disease samples
This trial builds a European “registry and biobank” of children with suspected or confirmed interstitial lung disease (a type of lung problem), as well as conditions that can look similar. It helps researchers learn more about these rare childhood lung diseases and connect families to future studies.
Hanover, Lower SaxonyAges Any age - NCT02180178Recruiting
Heart catheter registry for slow coronary blood flow
This study builds a database of people who are having a coronary angiography (a heart blood-vessel X-ray test). It aims to better understand conditions like slow blood flow in the heart’s small vessels and may help improve how these conditions are diagnosed and treated.
MainzAges Any age - NCT02897908Recruiting
Noninvasive scan to check liver fat and scarring
This study tests a noninvasive FibroScan machine to help measure liver fat and possible liver scarring using information collected in a database. It may help researchers improve how liver problems like fat buildup and scarring are identified and tracked.
Buffalo, New YorkAges 18 years+ - NCT02714764Recruiting
Testing how best to measure outcomes in Alexander disease
This study is looking at which measurements best capture changes over time in people with Alexander disease. It may help researchers and doctors track the disease more accurately in future care and studies.
Philadelphia, PennsylvaniaAges Any age - NCT02683512Recruiting
Study of GBE deficiency in GSD IV and APBD
This study follows people with GBE deficiency caused by GSD IV or APBD to better understand how the condition works over time. It may help researchers and clinicians plan future care and treatments.
Durham, North CarolinaAges birth–90 years - NCT02270476Recruiting
Study of how cystic fibrosis lung disease changes over time
This observational study follows children newly diagnosed with cystic fibrosis to understand how their lung disease develops. It may help doctors better predict disease course and choose the right timing for care.
Heidelberg, Baden-WurttembergAges Any age - NCT02103361Recruiting
Pregnancy registry for Stelara or Tremfya exposure
This study is a pregnancy exposure registry. It collects information to better understand pregnancy outcomes after exposure to Stelara or Tremfya (medicines used for autoimmune diseases).
La Jolla, CaliforniaAges Any age - NCT02285582Recruiting
Rare blood disorder registry for histiocytic conditions

Birmingham, AlabamaAges Any age - NCT02253290Recruiting
Follow-up for kids with neuromuscular diseases
This study checks how children and teens with neuromuscular diseases are doing over time. It focuses on brain/learning thinking (neuropsychological) and emotional or social well-being (psychosocial) to understand what support may help.
LeuvenAges Up to 18 years - NCT02418442Recruiting
Kid rheumatic disease registry study for follow-up care

Birmingham, AlabamaAges Up to 21 years - NCT02450851Recruiting
Find answers for undiagnosed medical conditions using genetic testing
This study helps look for causes of health problems when no one has been able to give a diagnosis. It tests and shares medical and genetic information (with privacy protections) so researchers can better match findings to possible causes.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,808 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.
