Recruiting studies
- NCT03632239Enrolling by invitation
Share whole-genome or exome data for research
This trial is about building a large library of genetic test results (whole exome or whole genome sequencing) that researchers can use. You may be eligible if your sequencing data is available and you (or your study contact) can be reached again so researchers can include your information responsibly.

Deep health study of Gulf War veteran symptoms and brain-body changes
This study closely measures health, thinking, and body function in Gulf War veterans using detailed testing (including exercise testing and possibly brain scans). It aims to better understand what may be driving Gulf War illness and related symptoms, which could improve future care.
Bethesda, MarylandAges 48–70 - NCT06310226Recruiting
Studying spinal cord stimulation for chronic low back pain
This study is looking at how people with chronic low back pain respond to spinal cord stimulation (a device that sends gentle electrical pulses to the spine to reduce pain). If you already have a spinal cord stimulator, you may help researchers understand how well it works and how it affects your brain.
Los Angeles, CaliforniaAges 18–80 - NCT06695780Recruiting
Food habits and health in older adults
This study looks at the eating habits and overall health of older adults who live at home. You will do things like answer questions, take some samples (like blood) yourself, and use a video call — all from home.
Meylan, IsereAges 55–75 - NCT07124377Recruiting
Study of hereditary ATTR amyloidosis symptoms
This study looks at how a specific genetic change (Val50Met) affects people with hereditary ATTR amyloidosis. It may help doctors better understand the condition and its symptoms.
Charata, Chaco ProvinceAges 20 years+ - NCT07471074Recruiting
Study of stem cells in Waldenström macroglobulinemia
This study looks at bone marrow stem cells in people with Waldenström macroglobulinemia (WM). It aims to understand how these cells work and may help improve future treatments for WM.
AmiensAges 18 years+ - NCT06603584Recruiting
Studying wheezing patterns in young children
This study looks at different kinds of wheezing in young children (ages 1 to 5) to better understand what causes it and how to treat it. If your child has had wheezing more than once, this research could help find patterns that lead to better care.
SohagAges 2–6 - NCT07422090Recruiting
Preventing suicide with digital and genetic tools
This trial uses smartphone data and genetic testing to help prevent future suicide attempts. It aims to find personalized ways to support people who have already had a suicide attempt.
Madrid, MadridAges 12 years+ - NCT02692885Recruiting
Study body fat tissue to learn how it affects metabolism
This study looks at samples of body fat to understand what controls metabolism (how your body uses energy). You may be asked for a fat tissue sample during surgery or through a special biopsy scan, depending on your situation.
Bethesda, MarylandAges 18–90 - NCT05965258Recruiting
Classify mitral regurgitation using heart scans
This study uses heart imaging to better understand different types of mitral valve leak (mitral regurgitation) and how it relates to heart pumping function. Results may help doctors match people to the most appropriate care based on scan “patterns.”
Cleveland, OhioAges 18 years+ - NCT07245407Recruiting
Study of bronchiectasis types in Chinese patients
This study looks at different types of bronchiectasis in Chinese patients to understand the disease better. It may involve additional tests like lung function and questionnaires.

Common questions
- Are there clinical trials for phenotype?
- Yes. Clin2 currently lists 316 recruiting phenotype 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 phenotype 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 phenotype 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.
