Understanding and Diagnosing Pheochromocytoma and Paraganglioma
This study helps doctors better understand and diagnose pheochromocytoma and paraganglioma—rare tumors that release stress hormones and cause high blood pressure and other symptoms. Researchers will study your medical history, blood and urine tests, imaging scans, and genetic information to improve how these conditions are found and understood.
Bethesda, MarylandAges 3–120 - NCT01266577Recruiting
MRI study measuring brain and muscle chemical levels
This study uses MRI techniques to measure natural chemical “metabolites” in the brain and muscle. You may be able to join if you’re generally healthy and can safely complete a long MRI scan.
Bethesda, MarylandAges 18–65 - NCT00005909Recruiting
Understanding Alkaptonuria: A Research Study
This study examines alkaptonuria, a rare inherited condition where the body cannot break down certain amino acids, leading to dark urine and joint problems. Researchers want to learn more about how this disease develops and progresses to improve future treatments.
Bethesda, MarylandAges 2–115 - NCT00005917Recruiting

Bethesda, MarylandAges 1 month–70 years - NCT02089789Recruiting
Study of inherited glycosylation disorders for diagnosis
This study helps doctors diagnose congenital (from birth) glycosylation disorders, which are inherited conditions that affect how the body builds certain sugar-related proteins. You (or your child) may have clinic visits, blood or other samples, and possibly genetic testing—especially if there are family members with a known or suspected condition.
Bethesda, MarylandAges 1 month–80 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+ - NCT01905709Recruiting
Fecal transplant to treat recurring C. difficile infection
This trial studies using a fecal microbiota transplant (FMT)—healthy gut bacteria moved from a screened donor—to help treat recurring or hard-to-control C. difficile infection. It may help restore a healthier gut environment when standard treatments keep failing or the infection returns.
Englewood, New JerseyAges 18 years+ - NCT00078078Recruiting
Understanding Methylmalonic Acidemia and Cobalamin Disorders
This research study follows patients with methylmalonic acidemia (a rare metabolic disorder affecting how the body breaks down certain proteins) or cobalamin (vitamin B12) disorders to better understand how these conditions develop and progress over time. Researchers will collect medical information, blood samples, and eye exams to help improve future treatments.
Washington D.C., District of ColumbiaAges 1 month–115 years - NCT01571531Recruiting
Study after spinal cord injury within six weeks
This study is for people who have had a sudden spinal cord injury from trauma or a sudden lack of blood flow (ischemia) and can be assessed within six weeks. It aims to better understand spinal cord injury and may help guide future care.
ZurichAges 18 years+ - NCT01630850Recruiting
Islet cell transplant for brittle type 1 diabetes
This trial studies whether transplanting insulin-producing islet cells can improve blood sugar control and reduce severe low blood sugar in people with “brittle” type 1 diabetes. It’s meant for adults with long-standing insulin dependence and troublesome, hard-to-control hypoglycemia.
Chicago, IllinoisAges 18–70 - NCT00605878Recruiting
Skin microbiome study in healthy people and eczema patients
This study looks at the types of germs on the skin (skin microbiome) in healthy people and people with skin conditions, including atopic dermatitis (eczema). Researchers collect skin samples to understand how skin germs differ and how that may relate to skin health.
Bethesda, MarylandAges 2–100 - NCT01241864RecruitingPhase 2
Islet transplant for type 1 diabetes after kidney transplant
This trial tests whether transplanting insulin-producing “islet” cells can better control blood sugar in people who have already received a kidney transplant. It’s mainly for adults with type 1 diabetes whose body is no longer making enough insulin, while they are on kidney-transplant medicines.
Chicago, IllinoisAges 18–68 - NCT01459107RecruitingPhase 2
Upper arm transplant study using immune treatment
This trial tests replacing a missing or non-working lower arm/hand with a donated upper limb (transplant). It also uses a special immune treatment plan and bone marrow infusion to help the body accept the new limb, aiming to improve hand function and quality of life.
Baltimore, MarylandAges 18–69 - NCT00748254Recruiting
Laser imaging test for rheumatoid arthritis inflammation
This study uses a laser-based imaging method to “see” inflammation in people with rheumatoid arthritis. It may help researchers better understand how active joint inflammation looks and how it changes.
Ann Arbor, MichiganAges 18 years+ - NCT00801333Recruiting
Create patient-specific stem cells for research
This study uses adult body cells (from participants) to create special lab cells called stem cells for research. It’s mainly about whether cells can be made and studied, not about treating a disease.
JerusalemAges 18 years+ - NCT01087333Recruiting
Share blood samples to help study blood cancers and treatments
This study collects human samples (like blood or other specimens) to learn more about hairy cell leukemia and other leukemias. It also helps researchers develop new lab-made immune-based medicines for cancer treatment.
Bethesda, MarylandAges 18 years+ - NCT01354002Recruiting
Tissue banking for research at St. Jude

Huntsville, AlabamaAges Any age - NCT01889381RecruitingPhase 2
Transplanting facial and jaw bone using donor tissue
This trial studies a special surgery to replace part of the skull, face, and jaw using donor tissue. It also tests medicines to help your body accept the transplant, aiming to restore function and appearance after serious injury.
Baltimore, MarylandAges 18–65 - NCT01964261Recruiting

Training with a leg exoskeleton after stroke
This trial tests a “human–machine” leg exoskeleton system to help people with stroke improve standing and walking during rehab. You may be able to participate if you have certain levels of disability and spasticity, can safely stand and walk with help, and don’t have skin, joint, or medical issues that would make training unsafe.
Houston, TexasAges 18–75 - NCT02450851Recruiting
Find answers for undiagnosed medical conditions using genetic testing
This study helps look for causes of health problems when no one has been able to give a diagnosis. It tests and shares medical and genetic information (with privacy protections) so researchers can better match findings to possible causes.

Common questions
- Are there clinical trials for humans?
- Yes. Clin2 currently lists 1,241 recruiting humans 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 humans 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 humans 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.
