Recruiting studies

Brain imaging study of energy use and brain chemicals
This study uses MRI scans to measure how your brain uses energy and how certain brain chemicals are made. It’s for healthy adults and can help researchers understand normal brain chemistry and metabolism.
Dallas, TexasAges 18–60 - NCT04234724Recruiting
Study of how ANGPTL3 gene variants affect body functions
This study looks at how different ANGPTL3 gene versions may change normal body measurements (such as blood and metabolism). It may help researchers understand why these genetic differences affect health, especially related to fats (lipids) in the body.

Dallas, TexasAges 18–95 - NCT03632239Enrolling by invitation
Share whole-genome or exome data for research
This trial is about building a large library of genetic test results (whole exome or whole genome sequencing) that researchers can use. You may be eligible if your sequencing data is available and you (or your study contact) can be reached again so researchers can include your information responsibly.
Bethesda, MarylandAges 4–120 - NCT06217822RecruitingPhase 1
Testing a new radiation therapy for advanced prostate cancer
This trial tests a new radioactive drug, 225Ac-PSMA-Trillium, that targets prostate cancer cells. It is for people whose advanced prostate cancer has stopped responding to hormone therapy and may have spread.
Duarte, CaliforniaAges 18 years+ - NCT07173881Recruiting
Dairy product for mothers and breast milk health
This study tests whether a special dairy product for pregnant and breastfeeding women can change the makeup of their breast milk. It aims to see if it helps improve nutrition for both mother and baby.
La Plata, Buenos AiresAges 18 years+ - NCT02392442Enrolling by invitationPhase 2
Study drug-free lung irritation using endotoxin in healthy adults
This trial tests how putting a small amount of endotoxin into a specific part of the lung affects the body. It’s designed for healthy, nonsmoking adults, and may help researchers understand lung and immune responses.
Bethesda, MarylandAges 18–45 - NCT07161414RecruitingPhase 1
Study of rilvegostomig for advanced solid tumors
This trial tests an experimental drug called rilvegostomig, given as a shot under the skin, for people with advanced solid tumors that have spread or can't be removed and have already had standard treatments. The study checks how the body processes the drug and its safety.
Huntersville, North CarolinaAges 18 years+ - NCT06240546RecruitingPhase 1
Study of LPM6690176 for advanced solid tumors
This trial tests a new drug called LPM6690176 for people with advanced solid tumors that have not responded to standard treatments. The goal is to see if it is safe and how it affects the body.
BeijingAges 18–75 - NCT04476901RecruitingPhase 2
Study of donor stem cell treatment for non-ischemic heart failure
This Phase 2 trial tests whether donor “MSC” cells can improve heart function in people with non-ischemic dilated cardiomyopathy and reduced pumping strength. You may be eligible if your condition is already treated with standard heart medicines and you can safely undergo a heart catheterization and follow-up testing.
Stanford, CaliforniaAges 18–80 - NCT06475391Recruiting
L-arginine supplement for exercise performance
This study tests whether taking L-arginine (a natural amino acid supplement) can improve your performance during short, intense exercise like sprinting or weightlifting. If you are a healthy, active adult, you may be able to join.
Winnipeg, ManitobaAges 18–39 - NCT06877650RecruitingPhase 1/Phase 2
Study of JMT108 for advanced solid tumors

Common questions
- Are there clinical trials for humans?
- Yes. Clin2 currently lists 1,251 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.
