Study of KarXT effects based on CYP2D6 metabolism types
This study tests how the drug KarXT is processed in the body based on your CYP2D6 metabolism type. It helps researchers understand if different metabolizer types affect how the drug works and is cleared.
Anaheim, CaliforniaAges 18–65 - NCT05738252Recruiting
Frailty tests to assess surgical risk in gynecologic cancers
This trial studies simple “frailty” assessments (tests of strength, memory, and daily functioning) to better predict risk in people with gynecologic cancers who are planning or having surgery. If you qualify, the results may help doctors identify who needs extra support before and after surgery.
Hamilton, OntarioAges 55–110 - NCT07206095Recruiting
Better diagnosis for inherited red blood cell diseases
This trial aims to improve how doctors diagnose rare inherited anemias, including sickle cell disease and other conditions that destroy red blood cells. It may help if you have a confirmed or suspected diagnosis but need more clarity through advanced testing.
Barcelona, BarcelonaAges Any age - NCT07203768Recruiting
Study on how essential thrombocythemia evolves into polycythemia vera
This study watches how a blood condition called essential thrombocythemia (ET) changes into another condition called polycythemia vera (PV) in people with a specific JAK2 mutation. It aims to learn more about these changes and what happens to patients over time.
Rochester, MinnesotaAges 18–100 - NCT07205172Recruiting
Gum looks and teeth crowding in children
This study looks at how the appearance of the gums relates to crowding of teeth in children. It will examine kids in different stages of tooth development to see if there is a link.
RomaAges 5–16 - NCT06941662Recruiting
Huntington's disease biobank: remote monitoring study
This study is building a biobank to better understand Huntington's disease by using remote monitoring and deep phenotyping (collecting detailed health information). It may help develop better ways to track the disease and improve care for people with the Huntington's gene expansion.
Palo Alto, CaliforniaAges Any age - NCT07190209RecruitingPhase 3
Testing lunsekimig for COPD with frequent flare-ups
This trial tests a new medicine called lunsekimig for people with COPD that still causes flare-ups despite standard treatment. It focuses on people with higher blood eosinophils (a type of white blood cell). If you smoke or used to smoke and have had at least 2 moderate or 1 severe flare-up in the past year, this study may be an option.
Chandler, ArizonaAges 40–80 - NCT07189806Recruiting

LondonAges 18 years+ - NCT07190222RecruitingPhase 3
New medicine for COPD with frequent flare-ups
This study tests a new medicine called Lunsekimig for people with COPD that has frequent flare-ups and high eosinophil levels (a sign of inflammation). It aims to see if it can help control symptoms better than a placebo (a dummy treatment).
Birmingham, AlabamaAges 40–80 - NCT07187843Recruiting
Parkinson's type study: brain-first vs body-first
This study looks at how Parkinson's disease affects thinking, movement, and brain health differently depending on whether it starts in the brain or the body first. Participants will have tests and scans to track these differences over time.

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.
