Safety imaging study of a PET tracer in ALS, Alzheimer, MS, Parkinson
This early-phase study tests the safety of a radioactive tracer (“18F-OP-801”) and how the tracer moves through the body (biodistribution) in people with ALS, Alzheimer’s disease, multiple sclerosis, Parkinson’s disease, and in healthy volunteers. It also measures how the body processes the tracer (“pharmacokinetics”) to support future studies.
San Francisco, CaliforniaAges 18–80 - NCT05400499Recruiting
Deep brain stimulation study in Parkinson’s visuomotor function
This trial studies how deep brain stimulation affects hand-eye (visuomotor) coordination in people with Parkinson’s. It may help researchers understand whether the stimulation settings change movement control for daily tasks.
Cleveland, OhioAges Any age - NCT05405075Recruiting
Alzheimer’s research study with brain tests and blood samples
This study supports Alzheimer’s research by collecting health and thinking (cognitive) test results and blood samples to study genetics and biomarkers. You may be enrolled if you’re age 40 or older and can do these checkups, even if you have mild memory problems or dementia.
Phoenix, ArizonaAges 40 years+ - NCT05413655RecruitingPhase 2
Oral drug for mild Alzheimer’s disease symptoms
This Phase 2 trial tests an oral medicine (EX039) to see if it can help people with mild Alzheimer’s disease. It focuses on slowing or improving thinking and memory problems over time.
TaipeiAges 50–80 - NCT05414994Recruiting
Study eye bacteria in healthy and eye disease
This study compares the tiny living organisms (“ocular microbiome,” meaning eye-surface bacteria) in different eye conditions. It may help researchers understand how these eye bacteria relate to diseases and why some people develop problems with vision.
Nashville, TennesseeAges 18 years+ - NCT05422534RecruitingPhase 3
CoQ10 plus exercise for people with advanced kidney disease
This trial tests whether a supplement called CoQ10, along with supervised exercise, can improve how the body uses energy in people on chronic dialysis. It may help with muscle function and overall health if your heart and dialysis situation are stable enough.
Sacramento, CaliforniaAges 18–75 - NCT05424302Recruiting
Home virtual reality therapy for vestibular problems by location
This study looks at how well a home-based virtual reality (VR) vestibular therapy works for people with ongoing (chronic) balance problems, and whether results differ based on where the problem is in the inner ear. It may help your care team understand who benefits most from VR therapy.
Vancouver, British ColumbiaAges 18 years+ - NCT05424016Recruiting
Propranolol for brain blood-vessel tumors in VHL
This trial studies whether propranolol, a beta-blocker medicine, can help people with VHL who have non-urgent hemangioblastomas in the brain/spinal cord. It aims to see if the medication is safe and beneficial without needing immediate surgery.
Le Kremlin-BicêtreAges 18 years+ - NCT05427786RecruitingPhase 4
Nicotinamide-like heart medicine given during stent helps blood flow
This trial studies whether a medicine (nicorandil) given into a coronary artery during stent procedures can help keep blood flow from getting worse. It may help people having stent placement for coronary artery disease by improving how well blood moves through the treated area.
SeoulAges 19 years+ - NCT05434572Recruiting
Neuromuscular disease biobank for research samples
This trial is building a biobank (a secure research collection) from people with neuromuscular diseases, their families, or healthy volunteers. By joining, you help researchers study these conditions and improve future treatments.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,802 recruiting general population (no specific condition or disease) 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 general population (no specific condition or disease) 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 general population (no specific condition or disease) 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.
