Tagraxofusp for children with CD123-positive leukemia
This study tests tagraxofusp, a medicine that targets a marker called CD123 on cancer cells, in children and young adults whose leukemia or lymphoma has come back or is resistant to treatment. It may help by shrinking the cancer and improving disease control after standard therapies have not worked.
Los Angeles, CaliforniaAges 1–21 - NCT05479669Recruiting
Testing detailed heart scans in people with heart failure symptoms
This study looks at whether doing very detailed heart testing helps understand and guide care for people with heart failure with preserved pumping strength. You may be eligible if you’re an adult with specific symptom levels, recent heart-failure-related visits, and matching scan and blood test results.
GroningenAges 18 years+ - NCT05516628RecruitingPhase 2
Adjuvant atezolizumab plus bevacizumab after liver cancer surgery
This trial studies whether adding atezolizumab and bevacizumab after complete liver cancer surgery can lower the chance the cancer comes back. It also uses “multi-omics” tests (special lab tests on your tissue/blood) to help predict who is more likely to respond or resist treatment.
SingaporeAges 21–90 - NCT05528744Recruiting
Study genes and symptoms in ANKRD17-related CAGS
This study looks at how a specific gene change in ANKRD17 relates to the symptoms, brain/scan findings, and brain-cells in people with Chopra-Amiel-Gordon syndrome (CAGS). It may help families understand the condition better and connect gene results to what is seen clinically.
Boston, MassachusettsAges Any age - NCT05570227Recruiting
Study metabolism in melanoma using a glucose tracer
This study looks at how melanoma cells and the body use sugar by collecting tissue samples and, for some people, giving a labeled glucose infusion. It may help researchers understand melanoma “metabolic” patterns and how they relate to cancer behavior.
Melbourne, VictoriaAges 18 years+ - NCT05570929Recruiting
Study of kidney changes before and around donation
This study follows people who are planning kidney donation or a kidney transplant to better understand how kidney function changes over time. It may help researchers predict risk and improve care by studying health markers in detail.
BerlinAges 18–75 - NCT05574673Recruiting
Study of DNA repair traits in ovarian cancer patients
This study looks at certain “DNA repair traits” (called homologous recombination phenotype) in people with epithelial ovarian cancer. Results may help researchers better understand who responds to platinum chemotherapy, which is commonly used for this cancer.
København Ø, Region SjællandAges 18–100 - NCT05588167Recruiting
Niemann-Pick type C patient database and genetic data study
This study collects health information and genetic samples from people diagnosed with Niemann-Pick disease type C. The goal is to build a large database that can help researchers better understand the condition and improve future care.

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.
