Worldwide study of kidney injury in newborns
This study looks at how common acute kidney injury is in newborns in the intensive care unit. It helps doctors understand which babies are at risk and how to prevent kidney problems.
Birmingham, AlabamaAges birth–2 weeks - NCT06775496Recruiting
Study of life-threatening infections to find genetic causes
This trial studies people who have had a life-threatening infection to look for genetic reasons why some infections are so severe. If you or a child had a serious infection—like severe flu, meningitis, or a deep abscess—that could not be explained by a weak immune system from other causes, this study may help find answers.
Bologna, BolognaAges Any age - NCT06949579Recruiting
Risk of Eye Bulge in Highly Myopic Europeans
This study looks at the risk of a back-of-the-eye bulge (posterior staphyloma) in people with high myopia. It uses existing eye images to understand the anatomy of highly myopic eyes.
ParisAges 18 years+ - NCT03366506Recruiting
Study factors linked to ALS development
This study looks at people who might have amyotrophic lateral sclerosis (ALS) to understand what factors are associated with how the condition starts and develops. If you have a suspected or confirmed ALS diagnosis, it may help researchers learn what influences ALS and potentially guide future prevention or care.
JerusalemAges 12–120 - NCT06767267Recruiting
Study of ear infection in children
This study looks at children with a certain type of ear infection to learn more about it. It helps doctors understand the condition better.
BolognaAges Up to 14 years - NCT06322290Recruiting
Study of serious bacterial infections
This study is for people diagnosed with serious bacterial infections, specifically those caused by certain bacteria (pneumococcus, meningococcus, or haemophilus influenzae type b) that have spread throughout the body. The goal is to learn more about these infections and improve care.
AdriaAges 1 day–70 years - NCT04098133Recruiting
Tracking germs that resist key antibiotics in Swiss hospitals
This study collects and studies lab-detected germs in hospital patients that produce special enzymes making some antibiotics less effective. It helps researchers understand how these resistant germs spread over time in Switzerland.
BaselAges 18 years+ - NCT02900040Recruiting
Kidney transplant database and blood sample access study
This trial is about setting up and using a kidney-transplant database linked to stored blood/tissue samples. It may help researchers better understand kidney transplant outcomes and improve future care.
LyonAges 18 years+ - NCT04172025Recruiting
Swiss database for tracking hard-to-treat infections
This study builds a Swiss database using lab genetic testing (whole genome sequencing) plus basic patient information to track outbreaks of serious, drug-resistant, and sometimes high-infectious pathogens. Your data could help researchers understand how these germs spread and how to better prevent them.
BaselAges Any age - NCT07640581Recruiting
RSV Infection Study in Babies Under 2 Years
This study tracks how respiratory syncytial virus (RSV)—a common respiratory infection in babies—affects children under 24 months in Ho Chi Minh City. Researchers want to understand how often RSV happens, how severe it is, and how it impacts families, so they can better prepare healthcare services.
Ho Chi Minh City, Ho Chi MinhAges birth–2 years - NCT06393179Recruiting
Breathing pattern study for ICU patients on ventilators
This study looks at a specific breathing pattern in very sick patients on a ventilator. Researchers want to find the best way to treat this pattern, which may help you breathe better and recover faster.
Nanjing, JiangsuAges 18 years+ - NCT07255105Recruiting
Central line infections in ICU patients
This study is looking at infections from central lines (special IVs in large veins) in ICU patients across China. It aims to understand how common these infections are and what factors contribute to them.
Nanjing, JiangsuAges 18 years+ - NCT07181356Recruiting
Remote Ischemic Preconditioning for Heart Attack Recovery
This study tests whether a simple, noninvasive procedure called Remote Ischemic Preconditioning (RIPC) — where a blood pressure cuff is briefly tightened on an arm or leg — can improve long-term recovery for people who have had a heart attack. The treatment is done many times over a long period to see if it helps the heart heal and reduces future problems.
Zhengzhou, HenanAges 18 years+ - NCT07262515Recruiting
Blood tests and genes for alcoholic hepatitis recovery
This study looks at blood samples and genetic information from people with acute alcoholic hepatitis to understand why some recover better than others. It aims to find better ways to predict and improve outcomes.
ParisAges 18 years+ - NCT06946706Recruiting

Common questions
- Are there clinical trials for epidemiology?
- Yes. Clin2 currently lists 146 recruiting epidemiology 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 epidemiology 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 epidemiology 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.
