This trial builds a secure database by collecting information from adults who already have autosomal dominant polycystic kidney disease (ADPKD). Your information can help researchers understand the condition better and improve future care.
New York, New YorkAges 18 years+ - NCT01694940Recruiting
Mitochondrial disease registry and sample collection study
This trial builds a large database and collection of lab results, and possibly tissue samples, from people with suspected or diagnosed mitochondrial conditions. It helps researchers learn more about these disorders and mitochondrial DNA changes, which may improve future diagnosis and treatments.
San Diego, CaliforniaAges Any age - NCT01102556Recruiting
Pancreas disease registry for people at risk or with pancreatic cancer
This study collects health information and stored samples (biospecimens) to learn more about pancreatic diseases, including cancer and early warning changes. It may help researchers understand who is at higher risk and improve future testing and care.
New York, New YorkAges 18–85 - NCT01384721Recruiting
CT scan study for heart artery disease risk
This study uses a CT heart scan (with a calcium score) to better understand risk in people with suspected coronary artery disease. You may be asked to have scan-based measurements and then be followed for at least a year.
Milan, MIAges 18 years+ - NCT01192048Recruiting
Study genetics in congenital heart disease
This study looks at how genes may contribute to congenital heart disease. It may help researchers better understand causes and risk in families like yours.
Columbus, OhioAges Any age - NCT00267501Recruiting
Study collects data and samples to understand eosinophilic conditions
This study collects information and biological samples to better understand what causes certain allergic/eosinophilic conditions. It may help researchers learn mechanisms and improve future care.
Cincinnati, OhioAges Any age - NCT01193075Recruiting
Study of how Charcot-Marie-Tooth (CMT) develops over time
This study follows people who have Charcot-Marie-Tooth disease (CMT) and compares them with people without nerve disease. The goal is to better understand different CMT types and how symptoms and nerve test results change over time.
Los Angeles, CaliforniaAges Any age - NCT01873924Recruiting
Study of Batten disease symptoms and brain function
This study looks at how Batten disease affects the body and thinking/brain function. It may help researchers better understand the condition and how symptoms change over time.
Rochester, New YorkAges Any age - NCT00001230Recruiting
Understanding How Your Body Responds to Filarial Infection
This study looks at how the body's immune system reacts to filarial infections—parasitic worms that affect millions worldwide. Researchers will observe your infection and response to treatment to better understand the disease and improve future care.

Study of Crohn’s and ulcerative colitis in Seoul
This study looks at how inflammatory bowel disease (Crohn’s disease and ulcerative colitis) affects people in a specific area of Seoul. It mainly focuses on describing patterns and health needs rather than testing a new drug.
SeoulAges Any age - NCT01177618Recruiting
Study of early-onset severe COPD in younger adults
This study looks at people who develop COPD (a long-term lung breathing problem) at a younger age and have severe airflow limitation. It may help researchers better understand COPD in early-onset patients and find ways to improve care for this group.

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.
