Preventing graft-versus-host disease in kids after stem cell transplant
This trial tests whether removing certain immune cells (T cells) from the donor transplant can lower the risk of chronic graft-versus-host disease (long-term immune attack after transplant) in children and young adults with blood cancers. If you qualify, it may help improve transplant outcomes while tracking safety and side effects.
Los Angeles, CaliforniaAges 6 months–26 years - NCT03016819RecruitingPhase 3
Test drugs anlotinib and catequentinib for advanced sarcoma
This Phase 3 study tests two anti-cancer medicines (anlotinib and catequentinib) for people with certain advanced soft-tissue sarcomas, including alveolar soft part sarcoma, synovial sarcoma, and leiomyosarcoma. It is designed for tumors that cannot be removed and that have either grown despite treatment or no longer respond to standard options.
Phoenix, ArizonaAges 18 years+ - NCT03231241Recruiting
Study of worsening headaches using scans and blood testing
This study looks at why headaches can become long-lasting (“chronified”) by combining answers from online questionnaires, brain imaging, and blood protein tests. Your participation may help researchers find biological clues that could improve how headache problems are understood and treated.
Stanford, CaliforniaAges 18 years+ - NCT03428009Recruiting
Study links dystonia symptoms to genetic and brain differences
This study looks at how different types of dystonia (movement disorders) relate to genetics and brain findings from scans. You might help researchers understand why symptoms look different from person to person and what patterns may matter.
Dallas, TexasAges 11 years+ - NCT03716908Recruiting
Study of hearing gene changes in DFNA9 family members
This study looks at how a specific inherited gene change (the P51S COCH mutation) connects to hearing and balance symptoms over time. It may help researchers better predict who will develop symptoms and how they may progress.
AntwerpAges 18 years+ - NCT03841981Recruiting
Body fat and female hormone function study
This study looks at how body fat and exercise relate to how your ovaries work and how your hormones function. It may help explain why some women have irregular ovulation or hormone problems, and how lifestyle factors affect them.
Madrid, MadridAges 18–40 - NCT03865914Recruiting
Study linking diabetes kidney findings to biopsy results
This study looks at people with type 2 diabetes who have kidney problems and relates their symptoms and lab findings to what is seen on kidney biopsy. It may help doctors better understand what is driving kidney damage in diabetes.
Beijing, Beijing MunicipalityAges 18 years+ - NCT03885245RecruitingPhase 2
L-citrulline supplement for overweight adults with later-onset asthma
This Phase 2 trial tests whether adding L-citrulline can improve asthma control in overweight adults whose asthma started later in life. It compares your asthma symptoms and lung testing results to see if the supplement helps when asthma is already being treated.
Durham, North CarolinaAges 18–65 - NCT03981276Recruiting
Study aims to understand inherited walking stiffness disorders
This study looks at the causes and biology (“biomarkers”) of hereditary spastic paraplegias and related conditions. You may join as someone with the condition, a family member without symptoms, or a healthy person, to help researchers understand what’s happening in the nervous system.
InnsbruckAges Any age - NCT06289673RecruitingPhase 4
Collecting info to start treatment for new leukemia or lymphoma
This study gathers key health information at the start of treatment for children and teens newly diagnosed with certain types of leukemia or lymphoma. The goal is to find the best way to begin therapy right away, without waiting for extra tests.
San Diego, CaliforniaAges 1–18 - NCT04024631Recruiting
Study genes and diabetes risk using body measurements
This study looks at how genetic risk relates to developing type 2 diabetes, using information from a biobank and body measurements like weight. It may help researchers better identify who is at higher risk before diabetes starts.

Testing revumenib for relapsed acute leukemia with certain gene changes
This trial tests revumenib, a targeted medicine, to treat acute leukemia that has come back or hasn’t fully gone away. It may help people whose leukemia has specific gene changes (like KMT2A or NPM1) by trying to better control the cancer.
Duarte, CaliforniaAges 4 weeks+ - NCT04103268Recruiting
Study blood tests to understand organ injury in children with sepsis
This study uses special blood testing to learn what is happening in the immune system during sepsis in children and how it may relate to organ injury. Your results may help doctors recognize and treat sepsis earlier and more accurately.

Common questions
- Are there clinical trials for phenotype?
- Yes. Clin2 currently lists 315 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.
