Recruiting studies
- NCT05679206Recruiting
Postpartum care study for pregnancy blood-pressure complications
This study looks at people with preeclampsia during pregnancy and how their lung blood pressure and related symptoms change after delivery. It may help doctors better monitor and manage postpartum risks, especially involving the heart and lungs.
BernAges 16 years+ - NCT05679661Recruiting
Immunity-focused nutrition before surgery to reduce lung infections
This study gives an immunity-supporting nutrition plan and an oral cleaning product before and around surgery to help older adults avoid breathing-related complications. It is mainly for people at higher risk of post-surgery lung problems, and it checks whether the approach is safe and helpful.
BeijingAges 65 years+ - NCT05681624Recruiting
Extra oxygen during labor to support the baby
This trial studies whether giving extra oxygen to the pregnant person during labor helps the baby during “intrauterine resuscitation,” when monitoring suggests the baby needs support. It may help babies recover better while still in the womb, especially during continuous fetal monitoring.
St Louis, MissouriAges Any age - NCT05689775Recruiting
Robot-assisted reconstruction using tummy muscle flap after surgery
This trial studies a specific way to rebuild the pelvic floor (and sometimes the vagina) after major rectal or anal cancer surgery. It uses robotic surgery and a flap taken from your tummy muscle to help close and reconstruct the area.
OsloAges 18 years+ - NCT05696522Recruiting
Radiation to treat hard-to-control dangerous heart rhythm
This trial tests a focused type of radiation to treat ventricular tachycardia (VT) that keeps coming back despite other treatments. It may help people who cannot (or do not want to) have the usual catheter procedure to fix the rhythm.
LondonAges 18–85 - NCT05698628Recruiting
Timing strategies to protect legs during peripheral ECMO
This trial studies whether an “early” or more “conservative” approach to improving blood flow to the leg can prevent limb damage during a type of heart-lung machine called peripheral VA-ECMO. It may help reduce the risk of poor leg blood flow (ischemia) in people with severe heart failure-related shock.
SeoulAges 19 years+ - NCT05699174RecruitingPhase 3
Compare two antibiotic routes for infected broken bones after surgery
This Phase 3 trial tests whether giving antibiotics by mouth (PO) works as well as giving antibiotics through a vein (IV) for an infected fracture that has not healed after prior surgery. It may help you understand which approach is safer and more effective for getting the bone to heal.
Indianapolis, IndianaAges 18 years+ - NCT05702931RecruitingPhase 4
Semaglutide for high blood sugar after kidney transplant
This trial tests semaglutide, a medicine that helps lower blood sugar, in people who develop high blood sugar shortly after a kidney transplant. It may help control blood sugar without harming the transplanted kidney, while also checking safety in this specific group.
CopenhagenAges 18–80 - NCT05706766Recruiting
Exercise coaching before stem cell transplant for multiple myeloma
This trial studies whether a structured exercise program before an autologous (your own cells) stem cell transplant can improve health and fitness in people with multiple myeloma. The goal is to safely prepare your body for transplant, and the study includes fitness testing and ongoing exercise training.
Boston, MassachusettsAges 18 years+ - NCT05710809Recruiting
Exercise and health check study for older colorectal cancer patients
This trial looks at sarcopenia (loss of muscle strength/size) and vertigo (feeling dizzy or off-balance) in older adults with colorectal cancer. It tests whether a structured, exercise-based approach can help these issues alongside cancer care.
CopenhagenAges 65 years+ - NCT05711446Recruiting
Studying repeat urine leaks and bladder infections after kidney transplant
This study looks at how often kidney transplant patients get bladder infections after transplant, especially around routine follow-up visits. It may help the clinic find ways to lower infection risk after transplant.
New York, New YorkAges 18 years+ - NCT05715814RecruitingPhase 3
Test diabetes-pill type medicine on kidney dialysis safety
This Phase 3 trial studies the safety of an SGLT2 inhibitor (a diabetes medication that can affect kidney fluid handling) in people on peritoneal dialysis. The goal is to see how the treatment works in your type of dialysis and whether it causes any problems.
Toronto, OntarioAges 18 years+ - NCT05719467RecruitingPhase 3
Safety check of medicine to start labor
This Phase 3 study tests the safety of a medicine used to help start labor (“induction”). It may help by aiming for a safer, smoother induction process for people who are ready to deliver and meet specific pregnancy and health criteria.
LørenskogAges 18–50 - NCT05722782RecruitingPhase 2
Kidney stone pain treatment after ER discharge
This study compares an anti-inflammatory pain medicine (NSAID) given by mouth versus acetaminophen (paracetamol) or placebo after you leave the emergency room for a “renal colic” (kidney stone pain). It looks at whether the NSAID helps control pain better and whether it’s safe for people with uncomplicated kidney stone pain.
MonastirAges 18 years+ - NCT05739123Recruiting
Pregnancy safety registry for relugolix-containing medicines
This is an observational study that collects real-world information about pregnancy outcomes when relugolix-containing therapy is taken during pregnancy. It aims to better understand safety for both the parent during pregnancy and the child after birth.
Wilmington, North CarolinaAges birth+ - NCT05740033Recruiting
Closing the radial forearm donor site after mouth surgery
This study looks at how best to close the skin area on the forearm after surgeons take tissue to rebuild part of the mouth. If you need a radial forearm tissue reconstruction, you may be asked about outcomes afterward using English questionnaires.
Vancouver, British ColumbiaAges 18 years+ - NCT05754645Recruiting
Study of gut microbiome in weight-related pregnancy outcomes
This study looks at differences in the gut’s living microbes (microbiome) in people who are trying to conceive or are early in pregnancy, and how that may relate to pregnancy outcomes. It may help researchers understand whether microbiome changes are linked to healthier—or more complicated—pregnancies.
Rotterdam, South HollandAges 18–45 - NCT05755230Recruiting
Study of health results around surgery
This study follows people who are having surgery to see what happens before, during, and after the procedure. It may help doctors understand what factors are linked to better recovery.
Buenos AiresAges Any age - NCT05761275Recruiting
Sexual quality of life after minimally invasive benign surgery
This study looks at how minimally invasive “vNOTES” surgery affects women’s sexual quality of life after a non-cancer (benign) gynecologic procedure. You might be eligible if you recently had this type of surgery and meet specific health, infection, and language requirements.
GenevaAges 18–70 - NCT05763043RecruitingEarly Phase 1
IV iron (Monoferric) for low iron in pregnancy
This early study tests whether Monoferric, an IV iron medicine, safely and effectively treats iron deficiency during pregnancy when iron by mouth hasn’t worked or isn’t suitable. It may help you raise iron levels and improve anemia while using care your team already recommends.
Portland, OregonAges 18–65 - NCT05765162Recruiting
Research study on safer, more tailored anesthesia
This study looks at safer anesthesia—meaning medicines used during procedures—using a more personalized approach. It may help make anesthesia safer for adults having medical procedures.
Nykøbing FalsterAges 18–100 - NCT05769517Recruiting
Using ultrasound to predict BRCA genes from healthy ovaries
This study looks at whether pictures from a vaginal (transvaginal) ultrasound of a healthy ovary can help predict whether someone carries BRCA1 or BRCA2 gene changes. It may help identify people who could benefit from more genetic testing, without needing new ultrasound images.
