Salt Lake City, UtahAges 18 years+ - 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+ - NCT02602769Recruiting
Testing blood traits in children with ROHHAD syndrome
This trial studies children with ROHHAD syndrome to better understand their body chemistry and other blood features. The results may help researchers learn what drives the condition and how it might be tracked over time.

Using ARTIDIS to measure early breast lesions
This trial tests a new device called ARTIDIS that measures the stiffness of breast tissue to help identify early breast lesions. It may provide a noninvasive way to assess breast health.
Dallas, TexasAges 18 years+ - NCT06013423RecruitingPhase 2
Cord blood transplant with chemo and radiation for high-risk blood cancers
This trial tests a cord blood transplant after a reduced-intensity chemotherapy and radiation regimen for patients with high-risk blood cancers like leukemia, lymphoma, or MDS. The goal is to see if this approach can help destroy cancer cells and restore healthy blood cells.
Seattle, WashingtonAges 6 months–65 years - NCT05978141Recruiting
T-cell lymphoma registry study
This study creates a registry for people with certain T-cell or NK-cell lymphomas. It collects health information and tumor samples to learn more about these diseases and improve future treatments.

Common questions
- Are there clinical trials for phenotype?
- Yes. Clin2 currently lists 312 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.
