Replacing high-protein foods in chronic kidney disease
This study looks at how replacing high-protein foods affects people with chronic kidney disease. If you join, you will eat a carefully controlled diet to help researchers understand if changing your protein intake can improve your kidney health.
West Lafayette, IndianaAges 40–70 - NCT05575024Recruiting
Monitoring blood pressure and heart rhythm during kidney support in sepsis
This study looks at how stable blood pressure and heart rhythm are in people with sepsis who need continuous kidney filtration. If you qualify, it may help researchers better improve care for critically ill patients receiving this treatment.
SeoulAges 18 years+ - NCT07089901RecruitingPhase 4

Can a blood test replace bone marrow biopsy for low blood counts?
This study tries to see if blood tests can replace a bone marrow biopsy for people with low blood counts (cytopenia) and suspected MDS (myelodysplastic syndrome). It aims to make diagnosis less invasive by using a simple blood draw instead of a bone marrow sample.
San Diego, CaliforniaAges 18 years+ - NCT07074379Recruiting
Treating painless chronic pancreatitis with stones

Ottawa, OntarioAges 18 years+ - NCT07064434Recruiting
Nerve block for safer blood pressure control during hip replacement
This trial tests a type of nerve block (sacral canal block) to help manage blood pressure during hip replacement surgery. It aims to see if it can safely lower blood pressure on purpose, which may reduce bleeding and improve recovery.
Yinchuan, NingxiaAges 45 years+ - NCT07061223Enrolling by invitation

This trial tests two types of nerve blocks (SFIB and PENG) to find which provides better anesthesia during total hip replacement. It may help you understand which pain control approach could work best for your surgery.
MoscowAges 50–75 - NCT06659835Recruiting
Amino acid loss during kidney dialysis in the ICU
This study looks at how many amino acids (building blocks of protein) are lost during continuous kidney dialysis in patients in the intensive care unit after surgery. It may help doctors better understand how to support nutrition in these patients.
Vienna, State of ViennaAges 18 years+ - NCT07045233Enrolling by invitation

Common questions
- Are there clinical trials for replacement?
- Yes. Clin2 currently lists 507 recruiting replacement 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 replacement 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 replacement 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.
