Test food product for cholesterol balance and lipid levels
This trial tests whether ANKASCIN 568-P products can improve blood cholesterol levels (like LDL and HDL) in people with mild “lipid” (cholesterol/fat) imbalance. It may help by lowering “bad” cholesterol and improving balance, especially if you’re not taking cholesterol-lowering medicine right now.

This study tests whether unusual insulin action in the brain is linked to thinking problems and body/metabolic issues in schizophrenia. It may help researchers understand the cause and identify targets for future treatments.
Toronto, OntarioAges 17–45 - NCT05749822RecruitingPhase 2/Phase 3
Fenofibrate for primary biliary cholangitis with stable cirrhosis
This trial studies whether fenofibrate (a cholesterol medicine) can improve outcomes in people with primary biliary cholangitis (PBC) who already take ursodeoxycholic acid (UDCA) but still have abnormal liver blood tests. It specifically looks at people with “compensated” (stable) cirrhosis—meaning the liver disease is present but not causing severe complications right now.
Beijing, Beijing MunicipalityAges 18–75 - NCT05751967RecruitingPhase 3
Fenofibrate plus ursodeoxycholic acid for primary biliary cholangitis
This trial tests whether adding fenofibrate to ursodeoxycholic acid (UDCA) can improve liver test results in people with primary biliary cholangitis (PBC) who did not respond enough to UDCA alone. It aims to see if the combination works better and is safe for adults with persistent, abnormal liver markers.
Lanzhou, GansuAges 18–75 - NCT05753059RecruitingPhase 1
Study why some water pills stop working in heart failure
This Phase 1 study looks at why “water pills” (diuretics) like bumetanide may not remove fluid as expected in people with heart failure. The results may help clinicians improve treatment strategies for fluid control in the future.
New Haven, ConnecticutAges 18 years+ - NCT05753137Recruiting
Acupuncture along with glaucoma drops for mild or moderate glaucoma
This trial studies whether adding acupuncture to your usual glaucoma medication can help with glaucoma control in people with mild or moderate primary open-angle glaucoma. It compares acupuncture plus treatment versus treatment alone (randomly assigned).

Calgary, AlbertaAges 18–100 - NCT05759468RecruitingPhase 2
Add NAD to help protect kidneys in diabetes
This Phase 2 study tests whether adding NAD can improve kidney health in people with diabetes-related kidney disease. It is designed for people with certain urine lab results showing kidney stress, while keeping blood sugar and safety limits within range.
Boston, MassachusettsAges 30 years+ - NCT05762952RecruitingPhase 1
Dapagliflozin study for heart micro-blood-flow symptoms in women
This early-phase study tests whether dapagliflozin can improve tiny blood-vessel function in women who have heart-ache-like symptoms but no major blockage on heart scans. If it works, it may help symptoms related to “microvascular” heart circulation problems.
Charlottesville, VirginiaAges 18–99 - NCT05764057RecruitingPhase 3
Dapagliflozin to help the heart heal after a heart attack

Common questions
- Are there clinical trials for placebo?
- Yes. Clin2 currently lists 5,245 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.
