Providence, Rhode IslandAges 18–25 - NCT03739827Recruiting
Study rare solid tumors and collect your health samples
This study follows people (and sometimes family members) connected to rare solid tumors and collects health information and samples (biospecimens). It helps researchers understand how these cancers develop and builds resources for future research, which may benefit you by contributing to better tailored care for rare cancers.
Bethesda, MarylandAges 4 weeks+ - NCT06812143Recruiting
Strength Training Study for Adults 65 and Older
This study tests a strength training program designed for older adults who are not currently active. The goal is to find the best way to improve strength and overall health in people over 65.
Flushing, New YorkAges 65 years+ - NCT07163728Recruiting
Leptin as a marker for chemo sensitivity in new AML
This study is looking at a substance called leptin in the blood of people with newly diagnosed acute myeloid leukemia (AML). The goal is to see if leptin levels can help doctors predict how well chemotherapy will work, which could guide better treatment choices.
Fuzhou, FujianAges 18 years+ - NCT07179848RecruitingPhase 1
Temporal interference brain stimulation safety study in healthy adults
This trial tests a new type of non-invasive brain stimulation that uses a weak electrical field to gently influence brain activity. It is designed for healthy adults to see if the procedure is safe and comfortable, and to gather information that could help develop future treatments for mental health conditions.
TaipeiAges 20–65 - NCT07145450RecruitingPhase 1/Phase 2
T-cell therapy for advanced pancreatic cancer with KRAS mutations
This trial tests a personalized T-cell therapy designed to target pancreatic cancer cells that have a specific KRAS mutation (G12V or G12D). It is for people whose cancer has spread or is locally advanced and who have already benefited from standard treatments.
CopenhagenAges 18 years+ - NCT06773026RecruitingPhase 2
Sodium Phenylbutyrate for MCADD in Children and Adults
This trial tests a medicine called sodium phenylbutyrate (ACER-001) to see if it helps people with MCADD, a genetic condition that affects how your body breaks down fats. If you have MCADD and the common gene change, you might be able to join.

Common questions
- Are there clinical trials for adult?
- Yes. Clin2 currently lists 3,743 recruiting adult 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 adult 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 adult 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.
