This trial looks at ways to predict how kidney disease may develop, change, or cause complications using information from patients. It may help doctors identify people at higher risk and tailor care earlier.
ToulouseAges 18–99 - NCT05312658Enrolling by invitation
Aortic compression during C-section to reduce blood loss
This trial studies whether gently compressing the major blood vessel in the abdomen during a C-section can reduce blood loss. It may help you stay safer during surgery, especially by lowering the chance of heavy bleeding.
StockholmAges 18 years+ - NCT05279170Recruiting
Mask anesthesia with gentle throat pressure to prevent stomach air
This trial studies a way to hold gentle pressure near the throat during mask anesthesia (with or without a breathing tube) to reduce air going into the stomach. It may help lower the chance of “stomach insufflation” during elective surgery in young children.
LilleAges 2–10 - NCT05285878Enrolling by invitationPhase 2
Fingolimod to protect kidney function after kidney transplant
This trial tests whether fingolimod can reduce kidney scarring and preserve kidney function after a new kidney transplant. It focuses on people who are in the early period after transplant who may be at risk for scarring in the kidney.
Houston, TexasAges 18–65 - NCT05273424Enrolling by invitation
Study of outcomes for people on long-term dialysis
This study looks at health outcomes for people living with chronic kidney disease who have been on hemodialysis for more than 90 days. It may help doctors better understand what to expect over time and how dialysis care can be improved in Brazil.
Pelotas, Rio Grande do SulAges 18 years+ - NCT05213572Recruiting
Deep health check study for adults with sickle cell disease
This study looks at how major organs like the brain, kidneys, heart, and liver are affected in adults with sickle cell disease, whether they've had a bone marrow transplant or gene therapy, or are continuing regular treatment. You'll get detailed tests that can help doctors understand the disease better, which may lead to improved care.
Bethesda, MarylandAges 18–100 - NCT05254041Recruiting
Testing suction to help remove an IUD with a menstrual cup
This study looks at whether gentle suction can help safely remove an IUD when using a menstrual cup at the same time. It may help if your IUD needs removal, and the researchers are testing a specific removal method.
Denver, ColoradoAges 18–45 - NCT05236062Recruiting
Exercise during steroid treatment for GVHD
This study looks at whether doing moderate-to-vigorous exercise can reduce complications from corticosteroids in people with newly diagnosed GVHD. It may help your body tolerate steroids better, while checking exercise safety during treatment.
Boston, MassachusettsAges 18 years+ - NCT05199025Recruiting
Study of blood and lab markers around major surgeries
This study checks blood and other lab “biomarkers” during the time before and after major surgeries to see if they can help guide perioperative care. You might be eligible if you are having certain planned heart, lung, GI, or blood-vessel surgeries and can give informed consent.
Breda, North BrabantAges 18 years+ - NCT05226247Recruiting
Check whether careful weaning prevents lung fluid buildup
This study looks at people on a breathing machine for more than 48 hours who are starting a “spontaneous breathing trial,” a test used to see if they can breathe on their own. It focuses on those at higher risk of “weaning-induced pulmonary edema,” meaning fluid can collect in the lungs during the weaning process.
DijonAges 18 years+ - NCT05211661Recruiting
Diaphragm health during breathing machine support
This study looks at how the diaphragm (the main breathing muscle) changes when a person is on a breathing machine in the intensive care unit. It may help doctors understand how to better support breathing and recovery.

Blood thinner drugs vs aspirin to prevent clot problems
This trial compares apixaban or rivaroxaban (blood thinners) against aspirin to prevent future clot-related complications in people with certain bone marrow diseases (PV, ET, or pre-PMF) that have a specific JAK2 mutation. It may help lower the risk of clots, but it also carefully considers bleeding risk.

Long-acting tacrolimus after liver transplant
This trial studies whether taking an extended-release form of tacrolimus (a medicine to prevent transplant rejection) after a liver transplant works well for people who are followed at the University of Alberta. It may help simplify dosing and monitor safety and effectiveness after transplant.
Edmonton, AlbertaAges 18 years+ - NCT05224726Recruiting
Platelet-rich plasma for healing after C-section
This study tests whether a treatment made from your own platelets (platelet-rich plasma) can help the uterus heal after an elective C-section. You may be considered if you are full-term and having a planned C-section.

This study tests whether using surgical mesh can be done safely and works well in breast reconstruction done right away, in front of the chest muscle (pre-pectoral) using tissue expanders. It may help improve how the reconstructed area holds up, but you’d need to meet specific surgical and health requirements.

Common questions
- Are there clinical trials for complication?
- Yes. Clin2 currently lists 1,080 recruiting complication 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 complication 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 complication 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.
