Volunteer-led lifestyle program for older adults with muscle loss
This study tests a volunteer-led program to improve muscle health in older adults with sarcopenia. It uses a mobile app to guide exercise and nutrition, and aims to see if this approach helps people regain strength.
Hong KongAges 60 years+ - NCT07370155RecruitingPhase 1
Testing a new drug's safety in healthy volunteers
This study tests an investigational drug called Migaldendranib in healthy adults to see if it's safe and how the body handles it. It will help decide if further testing is possible.

Common questions
- Are there clinical trials for volunteers?
- Yes. Clin2 currently lists 529 recruiting volunteers 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 volunteers 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 volunteers 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.
