Proton or photon radiation for retroperitoneal sarcoma
This trial tests two types of external beam radiation—protons or photons—in people with retroperitoneal (in the back of the abdomen) soft tissue sarcoma. It’s an early-phase study meant to see how well the radiation can control measurable tumors while tracking safety.
Chicago, IllinoisAges 18 years+ - NCT01650311Recruiting
Study how serotonin signals work in inflammatory bowel disease
This study looks at how the body’s serotonin system behaves in people with Crohn’s disease or ulcerative colitis, compared with healthy people. It may help researchers understand disease biology and why symptoms can differ from person to person.
Hamilton, OntarioAges 19–85 - NCT01453127Enrolling by invitationPhase 4
DaTscan scan for aging and movement brain conditions
This trial uses a special brain scan called DaTscan to study how certain brain conditions change with aging and over time. It may help researchers better understand movement and other neurodegenerative conditions and who may benefit from future treatments.

This study collects and stores tumor/tissue information and family medical history from people with certain blood cancers. It aims to help researchers understand why these illnesses may run in families and use genetic clues for future research.
Boston, MassachusettsAges 18 years+ - NCT01186133Recruiting
Testing drug-coated stents in routine heart artery treatment
This trial looks at how different types of drug-coated stents work in everyday care for people with blocked heart arteries. It may help doctors choose the best stent type to keep the artery open after treatment.
Multiple LocationsAges 19 years+ - NCT01209000Recruiting
Study for children with new kidney protein loss
This study is for children (and some newly diagnosed patients) who have nephrotic syndrome—kidneys leaking a lot of protein. It aims to better understand the kidney condition (sometimes using biopsy) and support future care decisions.
Los Angeles, CaliforniaAges Up to 80 years - NCT01193647Enrolling by invitation
Study genetics that may raise rotator cuff injury risk
This study looks at genetic (inherited) factors that may make some people more likely to develop rotator cuff tears. You may be able to join if you’ve had a shoulder MRI for pain or you’re a close family member of someone with a documented tear.
Salt Lake City, UtahAges 18 years+ - NCT00830557Recruiting
Share information and donate tissue samples for pancreatic illnesses
This study collects health information and tissue samples from people with pancreatic cancer or other pancreatic conditions. Your participation may help researchers better understand these diseases and improve future care.
Phoenix, ArizonaAges 18 years+ - NCT00807482Recruiting
Study of lung disease causes in primary ciliary dyskinesia
This study looks at how primary ciliary dyskinesia (PCD—a lifelong problem with tiny lung “sweepers”) affects the lungs. You may be able to join if you strongly seem to have PCD based on symptoms, or if you’re a healthy person with a close family member who has confirmed PCD.
Chapel Hill, North CarolinaAges Any age - NCT00762333Recruiting
Blood tests after a heart attack to study heart strain markers
This study looks at blood test “markers” soon after an acute heart attack, to better understand heart damage and whether heart failure is present. It may help doctors improve how they monitor recovery and risk in people after a heart attack.
Farmington, ConnecticutAges 18 years+ - NCT01016613Enrolling by invitation
Kidney health study that helps build a tissue and data bank
This study collects health information and biological samples to better understand kidney disease and support future kidney research. It may help your care indirectly by improving how kidney conditions are recognized and studied.
Ann Arbor, MichiganAges Any age - NCT00471978Recruiting
Analyzing DNA from blood and lung tumor tissue
This study looks at DNA from blood samples and lung tumor tissue in people newly diagnosed with primary lung cancer. The goal is to learn more about the cancer’s biology and possibly guide better future care.
Boston, MassachusettsAges 18–120 - NCT00833599Enrolling by invitation
Scan lymph drainage and collect samples for related conditions
This study uses a special light scan after a dye is given to look at how your lymph system drains. It may also include genetic testing for people with a family history of lymph-related disorders to better understand causes.
Houston, TexasAges 3 months+ - NCT00588562Recruiting
Registry for inherited rare kidney stone disorders
This registry collects information from people with certain inherited rare kidney stone conditions. It helps researchers learn about the conditions and supports future studies that may improve care.
Rochester, MinnesotaAges birth–100 years - NCT00575081Recruiting
Brain mapping during stereotactic procedures
This study builds a “brain atlas” by collecting information during stereotactic brain procedures. It may help doctors better plan and understand these brain procedures in the future.
Nashville, TennesseeAges 6–90 - NCT00106015Recruiting
Diamond Blackfan Anemia Registry Study
This study collects information from patients with Diamond Blackfan Anemia (DBA), a rare blood disorder that affects red blood cell production. By joining this registry, you help doctors better understand DBA and improve treatments for patients like you.
New Hyde Park, New YorkAges Any age - NCT00378924Recruiting
Cardiology health study using blood or cheek swabs
This registry collects health information and samples (a blood draw or cheek swab) from adults to help researchers study heart-related conditions. You may qualify whether or not you currently have heart disease, as long as you can safely provide a sample and consent.
Atlanta, GeorgiaAges 20 years+ - NCT01137825Recruiting
Older patient cancer registry for a health check
This study is a registry that collects information from older adults who may be dealing with cancer. It includes a short health and function check to help doctors understand needs and guide care, even for people who turn out not to have cancer.
Boone, North CarolinaAges 65 years+ - NCT00899626Recruiting
Collecting stool and tissue markers from people with bowel conditions
This study collects samples (like tissue and other body fluids) from people who are getting a colonoscopy or similar camera test. It aims to find “biomarkers,” which are measurable signals that may help doctors better understand or detect bowel problems such as colorectal cancer, polyps, or inflammatory bowel disease.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,548 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.
