Guided fluid management in severe kidney failure using ultrasound
This study tests a new way to manage fluids in patients with acute kidney injury who are receiving a type of dialysis called continuous renal replacement therapy. The method uses ultrasound to check blood flow in the veins and kidneys to guide fluid decisions, which may help recovery.
BangkokAges 18 years+ - NCT07334691Recruiting
Trial of a new tricuspid valve replacement device
This trial tests a new catheter-based device to replace your tricuspid valve without open-heart surgery. It's for people with severe tricuspid regurgitation who are at high risk for surgery.
BonnAges 18–85 - NCT06862180Recruiting
Meal replacement for diabetes control trial
This trial tests whether replacing one meal a day with a special shake can help people with type 2 diabetes improve their blood sugar control and overall health. If you have type 2 diabetes, take diabetes pills, and your blood sugar is not well controlled (HbA1c 7–10%), you may be able to join.
Kubang Kerian, KelantanAges 30–65 - NCT07333560Recruiting
Predicting recovery after hip or knee replacement
This study is developing a tool that uses machine learning to predict how well you will recover after hip or knee replacement surgery. It aims to help doctors create better recovery plans for people like you.
BolognaAges 18 years+ - NCT07299942Recruiting
Beta-glucan supplement for weight loss in women
This trial tests whether taking a beta-glucan supplement (a type of fiber) during a calorie- and carb-restricted diet helps with losing body weight and fat, controlling appetite, and managing hunger hormones. It is for healthy women who are overweight or obese and not following a special diet.
GlasgowAges 18–60 - NCT04029337Recruiting
Transcatheter mitral valve replacement for severe leakage
This study tests a new device that replaces a leaking mitral valve without open-heart surgery. It may help people who have severe mitral valve leakage but cannot safely have standard surgery or some other less invasive valve repairs.
Tucson, ArizonaAges 18 years+ - NCT07281885Recruiting

This study tests whether aromatherapy with essential oils can help reduce nausea and vomiting after total joint replacement surgery. Participants will receive a simple aromatherapy treatment alongside their regular care.
Wong Tai Sin, Hong KongAges 18 years+ - NCT06888908Recruiting
Blood volume changes during hip replacement surgery
This trial measures how blood volume and fluids shift in the body during and after hip replacement surgery. It helps doctors better understand fluid management for patients having this procedure.
CopenhagenAges 18 years+ - NCT07275983Recruiting
Knee replacement recovery: spinal vs. general anesthesia
This study looks at recovery after total knee replacement surgery. It compares people who had spinal anesthesia (numbing the lower body) to those who had general anesthesia (being fully asleep) to see which group recovers better.
StrasbourgAges 18 years+ - NCT07278323RecruitingPhase 4
Hormone therapy for frozen shoulder
This study tests if hormone replacement therapy can help treat frozen shoulder. It is designed for people with frozen shoulder in just one shoulder who are not currently using hormones and have no history of hormone-sensitive cancer.
San Francisco, CaliforniaAges 40 years+ - NCT07205393Recruiting
Heart rehab after valve replacement surgery
This trial tests a phase one cardiac rehabilitation program for people who have had their mitral or aortic heart valve replaced. It aims to see if the rehab helps recovery. You might qualify if you had planned (not emergency) valve surgery and are stable enough for light exercise.
QinaAges 40–55 - NCT07183592Recruiting
Changing IV tubing in the ICU: does less often harm?
This trial compares changing the tubing attached to central lines every 4 days versus every 7 days, to see if less frequent changes cause more infections. If you have a central line in the ICU that will stay in for at least a week, this study may help decide the safest schedule.
Saint-Pierre, La RéunionAges 18 years+ - NCT07168330Recruiting
How well does ankle replacement work? A long-term look
This study checks how well total ankle replacements work over time, using patient reports and X-rays. It may help you understand your own recovery and improve care for others.
MilanAges 18–90 - NCT07150559Recruiting
Arch-clamping under mild cooling for acute aortic dissection
This trial tests a surgical technique called arch-clamping under mild hypothermia (cooling the body slightly during surgery) to treat acute type A aortic dissection. It may help patients who need immediate total aortic arch replacement.
Beijing, Beijing MunicipalityAges 18–70 - NCT07151989Enrolling by invitation
How valve disease type affects new valve durability
This study looks at people who had their mitral valve replaced to see if the original valve problem (tight vs leaky) affects how long the new valve lasts. It may help doctors understand which patients need closer follow-up.

- 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.
