Atezolizumab plus chemo for small cell bladder cancer
This trial studies whether a drug called atezolizumab combined with chemotherapy (etoposide and a platinum drug) can shrink or control small cell bladder cancer. It may help by boosting the immune system against the cancer while the chemotherapy treats fast-growing cancer cells.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05361720RecruitingPhase 2
Genetic test to match treatment for advanced kidney cancer
This study looks at genetic (RNA) testing of kidney cancer tissue to help choose the best drug treatment. It may help guide therapy for people with advanced or metastatic clear cell kidney cancer who are starting treatment for the first time.
Duarte, CaliforniaAges 18 years+ - NCT05316129RecruitingPhase 1
Trial of your own engineered T cells for ovarian cancer
This Phase 1 study tests whether giving your own immune cells—engineered to target the FSH receptor—can control recurrent ovarian-related cancers. It’s mainly looking at safety and early signs of activity for patients whose cancer has not responded well to standard platinum chemotherapy.
Tampa, FloridaAges 18 years+ - NCT05334979Recruiting
Study oxalate and citrate in people with and without kidney stones
This study compares urine levels of oxalate and citrate in adults who have had calcium kidney stones and adults who have never had stones. It may help researchers understand how these urine chemicals relate to stone risk.
Chicago, IllinoisAges 18–70 - NCT05354869Recruiting
Electrical stimulation therapy for pelvic floor muscle pain
This trial tests a treatment that uses gentle electrical stimulation through the vagina to reduce long-term pelvic pain caused by tight pelvic floor muscles. You might join if your pain has lasted over 6 months and exam shows specific muscle “trigger points.”
Los Angeles, CaliforniaAges 18–65 - NCT05362292RecruitingPhase 4
Treating bladder leakage to support mind and body health
This study tests medicines to reduce “urgency” urine leakage (when you suddenly feel you must go) and to see whether improving bladder control also helps overall mental and physical health. You may be eligible if you have had these symptoms for at least 3 months and can follow the study plan.
Palo Alto, CaliforniaAges 60 years+ - NCT05334706RecruitingPhase 4
Vaccine study to lower HPV spread in HPV-positive women
This Phase 4 study tests whether a 9-type HPV vaccine (9vHPV) can reduce how infectious HPV is and lower the chance of HPV spreading in women who already have HPV16 and/or HPV18. It focuses on specific HPV-positive women recently diagnosed and compares what happens after vaccination.
L'Hospitalet de Llobregat, CataloniaAges 18 years+ - NCT05353660Recruiting
Study diet and muscle loss in people with kidney disease
This trial is for adults with chronic kidney disease and low muscle strength (sarcopenia). It aims to find ways to improve outcomes, especially if you have a higher risk of complications.
Guangzhou, GuangdongAges 18–80 - NCT05318196Recruiting
Predict kidney disease risk and progression from patient data
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 - NCT05316493RecruitingPhase 2/Phase 3
Weight-loss and progesterone treatments for early uterine lining disease
This trial studies a weight-management approach plus a progesterone-releasing IUD (LNG-IUS) and megestrol to treat endometrial atypical hyperplasia, a high-risk precancer of the uterine lining. It may help shrink or control the abnormal cells while supporting fertility or keeping the uterus.
ShanghaiAges 18–45 - NCT05340465RecruitingPhase 2
IV iron in preterm babies to reduce blood transfusions
This Phase 2 study tests whether giving a specific IV iron (darbe plus IV iron) can help preterm babies need fewer blood transfusions while still keeping their iron levels in a safe range. It focuses on babies in the NICU who were born early, and it compares transfusion use and iron sufficiency over time.
Seattle, WashingtonAges Up to 3 days - NCT05313945Recruiting
Compare comfort after passive vs active catheter removal
This study tests which method of removing an in-place urinary (bladder) catheter is more satisfying and comfortable for patients after certain urologic procedures. If you qualify, you may be randomly assigned to one of two removal approaches and asked about your experience.
GrenobleAges 18 years+ - NCT05325008RecruitingPhase 3
IVIG treatment for BK virus after kidney transplant
This Phase 3 trial tests IVIG (an antibody medicine given through a vein) to treat BK virus infection after kidney or pancreas-kidney transplant. It may help lower the BK virus in the blood and protect the transplanted kidney.
Canberra, Australian Capital TerritoryAges 2 years+ - NCT05319015RecruitingPhase 2
Combination drug therapy before surgery for kidney cancer with vena cava clot
This trial tests two drugs, lenvatinib and pembrolizumab, given before surgery to shrink kidney cancer that has spread into the large vein carrying blood to the heart (the vena cava). The goal is to see if this approach makes surgery more effective and improves outcomes.
Dallas, TexasAges 18 years+ - NCT05361122Recruiting
Study to prevent developmental delays using xylitol
This study looks at whether giving xylitol can help prevent developmental delays in children. Families will do several developmental checkups, including tests done at a specific travel site, to see how children are doing.
LilongweAges 4–8 - NCT05337072Recruiting
Finding the cause of chronic endometritis in IVF patients
This study looks for a possible infection-related cause of chronic endometritis (a long-lasting inflammation inside the uterus) in people preparing for IVF/ICSI, to help find the best treatment. It involves a diagnostic hysteroscopy and may help doctors choose the most effective steps to improve pregnancy chances.
BrusselsAges Any age - NCT05358483Recruiting
Study of mothers and babies’ health factors
This study follows women planning pregnancy and their children for many years to understand what social and health factors shape outcomes for mothers and infants. Your participation may help researchers better understand risks and protective factors before and after birth.
Chicago, IllinoisAges 18–44 - NCT05336890Recruiting
Using past oxygen data to predict risks after premature birth
This study builds a personalized computer model that uses earlier breathing/oxygen information from preterm infants to predict possible health or development outcomes by preschool age. It may help families and doctors better estimate risks and plan support, using information already collected in a previous study.
Chicago, IllinoisAges 7 months–6.9 years - 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+ - NCT05349292Recruiting
Check hemodilution’s effect on urine kidney stress markers
This study tests a technique used during planned heart bypass surgery to see whether it changes substances measured in urine that reflect kidney stress or injury. If you have upcoming elective bypass surgery, your team may collect blood and urine samples to study how your kidneys respond.
Baltimore, MarylandAges 18–70 - NCT03638999RecruitingEarly Phase 1
Aspirin or similar anti-inflammatory medicine for kidney stone stents
This early-phase study tests whether taking an anti-inflammatory medicine around the time of ureter stent placement can improve outcomes for people with kidney stones. It looks for participants who are getting a stent after a scope procedure and who can follow strict medication and health rules.
St Louis, MissouriAges 18 years+ - NCT04128709Recruiting
