AnyangAges 19 years+ - NCT05318417Recruiting
Cochlear implant study for one-sided deafness
This study checks whether cochlear implantation is safe and effective for people who have very poor hearing in one ear (single-sided deafness) while the other ear hears normally or nearly normally. You may be enrolled if you meet specific hearing test and health/surgery readiness requirements.
Palo Alto, CaliforniaAges 5 years+ - NCT05349955Recruiting
Primary care diabetes guideline program for older adults

Common questions
- Are there clinical trials for safety and effectiveness?
- Yes. Clin2 currently lists 395 recruiting safety and effectiveness 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 safety and effectiveness 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 safety and effectiveness 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.
