- NCT07806604Recruiting
Icotinib after surgery for early lung cancer with EGFR mutation
This trial studies a pill called icotinib, given after lung cancer surgery, to see if it helps prevent the cancer from returning in people with early-stage, EGFR-mutant non-small cell lung cancer. It is a real-world study, meaning it looks at how the treatment works in routine practice.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06770621Recruiting
Glucagon response study in new type 1 diabetes
This study looks at how the body makes glucagon (a hormone that raises blood sugar) in children and teens with new type 1 diabetes. It aims to understand why some people may have dangerous low blood sugars, so doctors can better prevent them in the future.
Brussels, Woluwe-saint-lambertAges 2–30 - NCT07805967Recruiting
Study of rare parkinsonian conditions
This study follows people with certain rare brain conditions that affect movement and thinking, such as multiple system atrophy, dementia with Lewy bodies, progressive supranuclear palsy, and corticobasal degeneration. It aims to learn more about how these conditions progress over time, which may help improve future care.
Changshu, JiangsuAges 18 years+ - NCT07034157Recruiting
Ultrasound screening and treatment for artery disease
This study tests if using ultrasound to screen for blocked neck and head arteries can improve treatment plans for people getting heart artery stents. It aims to find hidden blockages and tailor therapy to reduce stroke and other risks.
BeijingAges 18 years+ - NCT07373483Recruiting
Children's use of tablets and phones at home
This study watches how 3-5 year old children use tablets and smartphones at home. It aims to understand what devices they use and how parents' own habits or family background might affect screen time.
SheffieldAges 3–5 - NCT07463898Recruiting
Finding early heart markers in women with preeclampsia
This study looks for proteins in the blood that may show early signs of heart stress in pregnant women with preeclampsia, before symptoms appear. It also uses heart ultrasound to see how the heart changes during pregnancy, which could help find women at risk earlier.
AbujaAges 13–50 - NCT06401330RecruitingPhase 3
Personalized treatment for pediatric Wilms tumor
This study tailors treatment for children with Wilms tumor based on specific tumor features and risk factors. The goal is to give the right amount of therapy to each patient to minimize side effects while maintaining high cure rates.
Birmingham, AlabamaAges Up to 30 years - NCT07621614RecruitingPhase 2
Safe Surgery Guidance for Childhood Melanoma Using Genetics

Common questions
- Are there clinical trials for observational study?
- Yes. Clin2 currently lists 824 recruiting observational study 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 observational study 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 observational study 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.
