Check biomarkers during bronchoscopy in breathing and throat pre-cancer
This study looks at “biomarkers” (measurable signals in samples) taken during bronchoscopy or related procedures in people with severe airway pre-cancer or certain lung/throat cancers, and in healthy volunteers.

Bone marrow transplant prep for children with non-cancer blood disorders
This early-stage study tests a specific chemotherapy “conditioning” regimen to prepare the body for a bone marrow transplant in children with certain non-cancer blood or immune conditions. It may help the transplant work better, but it also carries risks from the chemotherapy and transplant process.
Phoenix, ArizonaAges Up to 20 years - NCT01900132Recruiting
Measures nerve and muscle signals in healthy people and patients
This study uses a painless electrical method to record how muscles and nerves work over time. It aims to better understand normal patterns (healthy volunteers) and to learn how these signals change in people with neuromuscular or movement-related conditions.
Bethesda, MarylandAges 2–110 - NCT02872532Recruiting
Freezing testicle tissue in children before cancer treatment
This trial studies how doctors collect and freeze a small piece of testicle tissue from boys to protect future fertility before treatments like chemotherapy or radiation. It may help families preserve options for having children later if testicular function is permanently affected.
Rochester, MinnesotaAges birth–17 years - NCT02670031Recruiting
Blood pressure study using heart MRI in adults
This study looks at how the heart muscle reacts in people with high blood pressure. You may have heart imaging (MRI) and blood pressure monitoring to understand patterns and potential ways to help.
SingaporeAges 21–99 - NCT02592291Recruiting
Using a phone app to help manage long-term health needs
This study tests a mobile phone system that helps people with long-term, complex health conditions manage daily life and get support. If you can use a smartphone and pass the study checks, you may be able to try the self-management tools.
Pittsburgh, PennsylvaniaAges 12 years+ - NCT02769975Recruiting
Check children and teens with hormone and metabolism problems
This study evaluates children (and sometimes relatives) who may have hormone (endocrine) or metabolism-related conditions. It helps doctors better understand these problems by doing a clinical evaluation.
Bethesda, MarylandAges 3 months–100 years - NCT02830308Recruiting
Adult study evaluating endocrine and metabolic health
This trial enrolls adults with known or suspected hormone (endocrine) or metabolism-related conditions for clinical evaluation. The goal is to help doctors assess and better understand what’s causing these health problems.
Bethesda, MarylandAges 18–100 - NCT02450006Recruiting
Intermountain INSPIRE health registry for patients and families

- Are there clinical trials for no condition?
- Yes. Clin2 currently lists 726 recruiting no condition 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 no condition 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 no condition 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.
