This study is a registry that collects information from older adults who may be dealing with cancer. It includes a short health and function check to help doctors understand needs and guide care, even for people who turn out not to have cancer.
Boone, North CarolinaAges 65 years+ - NCT00040352Recruiting
Understanding melanoma risk in families and individuals
This research study helps doctors understand why some people and families develop melanoma (a serious skin cancer), especially in unusual circumstances. Researchers will collect medical histories, examine skin, and may do genetic testing to identify risk factors that could help with earlier detection and prevention.
Bethesda, MarylandAges 4 weeks–99 years - NCT01604395Recruiting
Long-term growth hormone check for children with short stature
This study follows children who are short for their age and checks how safe and effective growth hormone is over the long term. It may help families understand expected benefits and side effects for their specific growth-related condition.
SeoulAges 2 years+ - NCT01425892Recruiting
Study of how Sjogren’s disease starts and changes over time
This study follows people with Sjogren’s disease to understand how it develops and how symptoms naturally change over time. The goal is to improve understanding and future care rather than provide a new immediate treatment.
Bethesda, MarylandAges 16–100 - NCT00026884Recruiting
Blood and tissue sample collection for cancer research
This study collects blood and tissue samples from people with cancer or suspected cancer, or from their blood relatives. Researchers use these samples to better understand cancer and develop new treatments.
Bethesda, MarylandAges 2 years+ - NCT00177268Recruiting
Collecting blood and tissue samples in skin diseases research
This study collects blood, urine, and possibly small tissue samples to learn more about cutaneous T-cell lymphoma (CTCL) and either eczema or atopic dermatitis. It may help researchers better understand these skin conditions and improve future treatments.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT00033137Recruiting
Genetic study of Birt-Hogg-Dubé syndrome and kidney cancer risk
This research study examines the genes behind Birt-Hogg-Dubé (BHD) syndrome, a condition that increases kidney cancer risk. Researchers want to understand who inherits this condition and how to better identify and help people at risk.
Bethesda, MarylandAges 2 years+ - NCT01962415RecruitingPhase 2
Reduced-intensity stem cell transplant for non-cancer disorders
This trial tests whether a gentler (reduced-intensity) conditioning treatment before a stem cell transplant works for non-cancer diseases. It uses specific donor stem cell matches and checks heart, lung, liver, and kidney function to help lower transplant stress while still aiming for benefit.
Pittsburgh, PennsylvaniaAges 2 months–55 years - NCT00358943Recruiting
Gaucher disease registry and pregnancy tracking study
This study creates a large, long-term record of people with Gaucher disease and details about pregnancy outcomes. It helps researchers better understand Gaucher over a person’s life and during pregnancy.
Phoenix, ArizonaAges Any age - NCT00091871Recruiting
Understanding familial high eosinophil disease in families
This study follows families with a genetic condition that causes high levels of white blood cells called eosinophils. Researchers want to understand how the disease develops and changes over time to help predict who may get worse and how to treat it better.

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,195 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.
