AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.
Birmingham, AlabamaAges Any age - NCT05031897RecruitingPhase 2
Haplo transplant with reduced donor mismatch and radiation
This trial tests a special bone marrow/stem cell transplant approach using a partially matched family donor, along with conditioning treatment that involves radiation. It aims to help treat certain blood cancers by replacing damaged blood-forming cells with new ones from the donor.
Philadephia, PennsylvaniaAges 18 years+ - NCT02840747Recruiting
Your CTCL or related skin lymphoma tissue samples study
This study collects stored tissue samples (from skin or other needed procedures) from people with CTCL, Sézary syndrome, or lymphomatoid papulosis, especially when you are starting or changing treatment. It’s meant to help researchers learn more about these illnesses and may support future research.
New York, New YorkAges 18 years+ - NCT06078865Recruiting
FX Shoulder Replacement Study
This study follows people who receive an FX shoulder replacement device to see how it works over time. It may be a good fit if you are planning this specific surgery with your doctor.
Gilbert, ArizonaAges Any age - NCT03920774Recruiting
Study of Familial Dysautonomia in People With IKBKAP Changes
This study looks at how familial dysautonomia (FD) progresses over time in people who have a confirmed IKBKAP genetic change. It may help doctors better understand the condition and plan future treatments.
New York, New YorkAges 4 years+ - NCT06077747Recruiting
Lumbar vein treatment for chronic headaches with nutcracker anatomy
This study tests a procedure called lumbar vein embolization to treat daily headaches that feel like pressure and get worse when lying down. It's for people who have a rare anatomy where a vein in the kidney is pinched (nutcracker physiology), and standard headache medicines haven't helped.
Jacksonville, FloridaAges 18 years+ - NCT06059391RecruitingPhase 2
Vaccine for stem cell donors to prevent CMV
This trial tests whether giving a CMV vaccine to stem cell donors can help protect recipients from CMV infection after transplant. It is for adults with specific blood cancers who are CMV-positive and have a matched related donor.
Duarte, CaliforniaAges 18–75 - NCT06066996RecruitingEarly Phase 1
Study of withdrawal symptoms when people vape less
This study looks at what happens when people who vape nicotine daily try to cut back. Researchers want to understand withdrawal symptoms and find better ways to help people reduce or quit vaping.
Baltimore, MarylandAges 21–55 - NCT02143830RecruitingPhase 2

This Phase 2 study tests a stem cell transplant approach using adjusted chemotherapy doses for people with Fanconi anemia. It may help replace damaged bone marrow and treat blood problems like severe aplastic anemia, MDS, or leukemia.
New York, New YorkAges 3 months+ - NCT02055105Recruiting
Study tests a blood test pattern in children with sepsis
This trial studies how a specific pattern in blood (called “molecular fingerprinting”) changes in children with suspected or developing sepsis. The goal is to help doctors better recognize sepsis early and understand how it progresses, which may improve care.

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,055 recruiting down syndrome 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 down syndrome 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 down syndrome 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.
