Philadelphia, PennsylvaniaAges 60 years+ - NCT05501756RecruitingPhase 2
Dose-tuning alemtuzumab for children before a stem cell transplant
This Phase 2 study looks at the best dose of alemtuzumab (a medicine used before transplant) for children undergoing a donor stem cell transplant for a non-cancer illness. It may help doctors fine-tune dosing to improve how the drug behaves in the body and make future transplant care more precise.
Cincinnati, OhioAges Any age - NCT05411445Recruiting
Study blood markers in blocked grafts after bypass surgery
This study looks at small particles in your blood to understand why bypass grafts can become blocked after coronary bypass surgery. It may help doctors better monitor and treat this complication by relating blood markers to what happens after surgery.
Cotignola, RavennaAges 40–80 - NCT05366218RecruitingPhase 1/Phase 2
Tafasitamab for kids with high-risk B-cell leukemia after relapse
This Phase 1/2 study tests tafasitamab in children and teens with B-lineage acute lymphoblastic leukemia (ALL) that has come back or did not respond. It is mainly for patients with specific high-risk leukemia changes and/or leukemia markers that stay after stem cell transplant or CAR T-cell therapy.
Freiburg im Breisgau, Baden-WurttembergAges 3–18 - NCT05283174Recruiting
Blood thinner use during stroke to predict outcomes
This study looks at how people doing well on certain blood thinners do when they have a stroke or bleeding while taking them. It will measure medication levels in your blood to understand stroke severity and recovery in the short and long term.
TaipeiAges 20 years+ - NCT05550298Recruiting
Study of virus infections after pediatric transplants
This study looks at how respiratory viruses behave and how the body responds in children who are about to receive, or have recently received, a transplant. It may help doctors better diagnose and treat viral infections in transplant patients by studying blood samples and test results.
Birmingham, AlabamaAges Up to 18 years - NCT05567289Recruiting
Precision medicine after stem cell transplant
This study looks at a personalized (“precision”) approach for people who have received a stem cell transplant from a donor. It may help doctors better tailor care after transplant, especially for children.
ManchesterAges Any age - NCT05318534RecruitingPhase 1
Testing a new medicine for Cold Agglutinin Disease
This Phase 1 study checks whether an investigational medicine is safe and tolerable, and how the body processes it. For people with Cold Agglutinin Disease, it also looks at early blood markers of whether the disease responds.
LeedsAges 18 years+ - NCT05386277Recruiting
Testing safety of an embolectomy catheter used during clot surgery
This study follows patients who are having surgery to remove a blood clot in an artery or vein and where a specific clot-removal catheter (the LeMaitre TufTex Single Lumen) is used. It aims to confirm how well the device works and monitor safety outcomes.
GenkAges 18 years+ - NCT04824950Recruiting
Blood DNA test in newly diagnosed mediastinal large B-cell lymphoma
This study looks at how “circulating tumor DNA” in blood changes in people with newly diagnosed primary mediastinal large B-cell lymphoma. It may help doctors better monitor treatment response alongside standard PET/CT-guided care, which could improve follow-up decisions.
LyonAges 18 years+ - NCT04760301Recruiting
Tranexamic acid during vaginal hysterectomy to reduce bleeding
This trial studies whether giving tranexamic acid during a vaginal hysterectomy (uterus removal through the vagina) can reduce blood loss. It may help some people need less bleeding during surgery, if they are able to take the medicine safely.
