Studying heart tissue and blood changes after advanced heart care
This trial studies how blood and heart tissue change in people with advanced heart failure who are getting an LVAD (a heart pump) or a heart transplant. It may help doctors better understand what’s happening in the heart before and after these treatments.
Murray, UtahAges 13 years+ - NCT01425892Recruiting
Study of how Sjogren’s disease starts and changes over time
This study follows people with Sjogren’s disease to understand how it develops and how symptoms naturally change over time. The goal is to improve understanding and future care rather than provide a new immediate treatment.
Bethesda, MarylandAges 16–100 - 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 - NCT00006518Recruiting
Tissue samples from people with viral infections or cancer
This study collects tissue and blood samples from people who have or have been exposed to certain viruses (HIV, KSHV, HPV, EBV, or HTLV-1) or who have developed cancer or precancerous skin lesions. The samples help researchers understand how these viruses may lead to cancer.
Bethesda, MarylandAges 18 years+ - NCT00345930Recruiting
Study of liver injury after medicines or supplements
This study looks at people (including children over age 2) who develop liver injury that may be caused by a drug or a complementary/alternative medicine (CAM) product. It helps doctors better understand what causes the injury and how to evaluate it.
Los Angeles, CaliforniaAges 2 years+ - NCT01838148Recruiting
Tests heart signals to detect reduced blood flow during exercise
This study looks at specific blood-flow and heart-rhythm signals during an exercise test to find signs of reduced blood flow to the heart. It may help doctors spot heart problems sooner and decide who needs more care.
BaselAges 18 years+ - NCT02061787Recruiting
Exercise testing to assess outcomes in pulmonary hypertension
This trial studies how well a treadmill/breathing exercise test can measure health outcomes in people with certain types of pulmonary hypertension. It may help your care team judge your status and track changes over time.
BeijingAges 5–100 - NCT01375530Recruiting
Volunteers needed for future medical research testing
This trial is looking for adult volunteers who agree to have blood and/or tissue samples collected and stored for later studies. It may help researchers better understand the immune system and future treatments, although it is mainly a sample-storage study rather than a specific drug treatment.
Atlanta, GeorgiaAges 18–60 - NCT01258231Recruiting
Genetic test to predict risks after heart surgery
This study looks for genetic (DNA) clues that may help predict side effects or complications after heart surgery. If you join, your genome information may be used to understand who is at higher risk and why.
Boston, MassachusettsAges 20–90 - NCT00026884Recruiting
Blood and tissue sample collection for cancer research
This study collects blood and tissue samples from people with cancer or suspected cancer, or from their blood relatives. Researchers use these samples to better understand cancer and develop new treatments.
Bethesda, MarylandAges 2 years+ - NCT01696734RecruitingPhase 3
Domperidone for difficult stomach and reflux problems
This trial studies whether domperidone can help people whose stomach or reflux symptoms did not improve with usual treatments. It focuses on symptoms like slow stomach emptying, hard-to-control acid reflux, or severe indigestion.
Houston, TexasAges 16 years+ - NCT01927783Recruiting

This study looks at whether deep brain stimulation surgery can help people with certain movement problems, chosen by a specialized team. You may be considered if medicines (or other treatments) aren’t controlling your symptoms well enough or if the condition causes major disability.
Bethesda, MarylandAges 18–99 - NCT00867269Recruiting
Study of causes and progression of low CD4 blood cells
This study looks for what causes and how idiopathic low CD4 cells happen over time, using blood and tissue samples. It may help doctors learn why this occurs and how to better track people with it.

Common questions
- Are there clinical trials for disease?
- Yes. Clin2 currently lists 9,506 recruiting 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 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 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.
