Study using gut samples to understand germs and your immune system
This study collects gut tissue (biopsies) and blood to learn how gut germs (microbes) and the immune system interact. It may help researchers understand why gut infections or immune problems happen and improve future treatments.
BernAges 18–80 - NCT05332899RecruitingPhase 1
Flu challenge study in healthy adults to test an investigational approach
This Phase 1 study tests an investigational influenza (flu) approach in a carefully selected group of healthy adults. It may help researchers understand how the flu challenge works and how well the treatment performs and is tolerated.
Atlanta, GeorgiaAges 18–49 - NCT05335811RecruitingPhase 1
PET scan test of a new radioactive drug for tumors and inflammation
This Phase 1 study tests whether a new PET imaging tracer (a small amount of radioactive medicine) is safe and how it moves through the body. It’s mainly for adults with cancer who have signs of inflammation or possible immune side effects, so doctors can see what’s happening in the body.
Houston, TexasAges 18 years+ - NCT05353504Recruiting
Testing how gut changes affect food choices
This study looks at whether interventions that change your gut bacteria can change how you decide what to eat. It may help researchers understand the gut–brain link behind eating behavior.
LeipzigAges 18–60 - NCT05353348Recruiting
Program to treat mild anemia around heart surgery
This trial tests a combined treatment plan to improve anemia (low blood count/iron levels) before and around the time of major elective heart surgery. It may help reduce the need for blood transfusions and support safer recovery.
Hangzhou, ZhejiangAges 18 years+ - NCT05355272RecruitingPhase 2
Growth hormone treatment for Gulf War illness with low growth hormone
This Phase 2 study tests whether replacing growth hormone can improve symptoms in veterans with Gulf War Illness and adult growth hormone deficiency. It also checks that the treatment is safe for people with stable medications and hormone regimens.
Houston, TexasAges 18–64 - NCT05357170Recruiting
Testing gut bacteria changes after severe ICU illnesses
This study looks at changes in the microbiome (gut bacteria) in adults after serious ICU illnesses like sepsis, major trauma, or open heart/abdominal surgery. It may help researchers understand why recovery can be harder in some people and guide future treatments.
Gainesville, FloridaAges 18–110 - NCT05361733RecruitingPhase 1
Safety and blood-drug study of XFB19 in healthy adults
This Phase 1 study tests whether XFB19 is safe and tolerable in healthy adults and how the drug moves through the body (what the blood levels look like). You would be in the study to help researchers understand early safety and dosing information.

Common questions
- Are there clinical trials for humans?
- Yes. Clin2 currently lists 1,243 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.
