GrazAges 18–80 - NCT05412381RecruitingPhase 3
PRP after ACL injury to help prevent knee arthritis
This study tests whether PRP (platelet-rich plasma) given after an ACL injury and surgery can lower the chance of developing long-term knee arthritis. It may help protect the knee over time by targeting early healing after ACL reconstruction.

Memory training study for older adults with mild memory problems
This trial tests an approach to improve learning and memory in people age 60+ with amnestic mild cognitive impairment (a specific type of early memory problem). It may help by supporting memory and learning skills, but it also has medication and health-history requirements.
Ann Arbor, MichiganAges 60 years+ - NCT05392764RecruitingPhase 3
SGLT2 medicine for high-risk people after sudden worsening heart failure
This Phase 3 trial tests whether starting an SGLT2 inhibitor early in the hospital can improve outcomes for people at high risk after acute (sudden) heart failure. If you qualify, you would be randomized to receive the study medicine or standard care, started within 12 hours of admission.

Common questions
- Are there clinical trials for placebo?
- Yes. Clin2 currently lists 5,154 recruiting placebo 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 placebo 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 placebo 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.
