MRI study of brain vein damage and swelling patterns
This pilot study uses an MRI scan that involves an injected contrast to look at how brain blood-flow pathways are being blocked or narrowed. The goal is to better understand the kind of damage caused by these vein problems, which may help doctors monitor and plan care.
Paris, ParisAges 18 years+ - NCT05024552RecruitingPhase 1
Vyxeos plus gilteritinib for certain relapsed AML
This Phase 1 trial studies whether combining Vyxeos (a chemotherapy) with gilteritinib (a targeted drug) can treat AML that has come back or hasn’t responded well, specifically AML with certain FLT3 mutations. If it works, it could improve chances of controlling the leukemia.
Tampa, FloridaAges 18 years+ - NCT05074316Recruiting

BrestAges 18 years+ - NCT05236582RecruitingPhase 2
Herombopag for low platelets from chemotherapy side effects
This Phase 2 trial studies herombopag to raise very low platelet counts caused by chemotherapy and reduce bleeding risk. It may help people whose platelet levels stay too low even after prior standard attempts like rhTPO or IL-11.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT05169242Recruiting
Preventing bleeding after colonoscopy using preventive clip placement
This trial tests whether placing small “preventive clips” during colonoscopy can reduce bleeding afterward in people who take blood thinners (DOACs). It may help lower the chance of bleeding after polyp removal or biopsy during a scheduled colonoscopy.
Shatin, New TerritoriesAges 18 years+ - NCT04745949RecruitingPhase 2
Testing first-line antibody plus immunotherapy for mediastinal lymphoma
This trial tests a combination of antibody therapy and immunotherapy (plus standard chemo) as first treatment for primary mediastinal large B-cell lymphoma. It may help shrink the lymphoma and improve how long patients stay in remission.
Houston, TexasAges 18 years+ - NCT04778657Recruiting
Study of inherited red-blood-cell disorders in France
This study follows people with inherited stomatocytosis (an inherited type of red-blood-cell disorder) to better understand these conditions. It may help researchers gather comprehensive information about diagnoses and care, which can improve future treatments.
Le Kremlin-BicêtreAges Any age - NCT04890041Recruiting
Testing TPO medicines for immune low platelets in teens
This trial studies whether “TPO” medicines (like eltrombopag or similar drugs) help people age 14 and older with primary immune thrombocytopenia (ITP) who did not respond well to first treatments. It may help raise platelet counts and reduce bleeding, especially when prior therapy hasn’t worked.
Tianjin, Tianjin MunicipalityAges 14 years+ - NCT05207657RecruitingPhase 1/Phase 2
Gene therapy for p47 form of chronic granulomatous disease
This trial tests an individualized gene therapy made from your own stem cells to help the immune system work better in p47-related chronic granulomatous disease (CGD). It’s designed for children who have serious infections or inflammation despite usual treatments and who don’t have a fully matched bone marrow donor.
LondonAges 1.9 years+ - NCT05077124Recruiting
CytoSorb safety registry for clot-fighting medicine removal
This registry collects information on people who use CytoSorb to remove clot-fighting medicines from the blood. It’s mainly meant to track safety and how quickly the removal works, which may help improve care for future patients.
GrazAges 18 years+ - NCT05086003RecruitingPhase 2
Kidney transplant with stem cell treatment to build immune tolerance
This Phase 2 study tests a combined treatment—kidney transplant plus stem cell–based immune therapy—to help the body accept the new kidney with less immune attack. You may be able to take part if you have a matching sibling donor and meet key safety and health requirements.
Petah TikvaAges 18–65 - NCT04689750Recruiting
Testing outcomes after donor CHIP in stem cell transplant
This study looks at how a genetic risk factor in a stem cell donor (called CHIP) may affect outcomes after an allogeneic (donor-to-recipient) stem cell transplant. It may help doctors better predict which donor factors are important for patient outcomes.
Hong KongAges 18 years+ - NCT04861103RecruitingPhase 4
Testing a blood thinner plan during pregnancy
This study looks at how people’s blood and clotting behave during pregnancy when taking a specific blood thinner called low molecular weight heparin (LMWH) three times a day. It may help doctors fine-tune how safely and effectively LMWH is used during pregnancy.
Orange, CaliforniaAges 18 years+ - NCT04668261Recruiting
Brain blood flow changes in neurosurgery patients over time
This study uses repeated MRI scans to measure how blood flow to the brain changes over time in people with certain neurosurgical conditions. It aims to better understand brain circulation changes, which may help doctors plan care more effectively.
ZurichAges 18 years+ - NCT04629833RecruitingPhase 3
Mesenchymal cells vs standard care for steroid-resistant graft-versus-host disease
This trial studies a type of immune-support cell therapy (mesenchymal stromal cells) compared with the best available standard treatment for acute graft-versus-host disease (aGvHD) that does not respond to steroids. It may help by calming an overactive immune reaction after a stem cell transplant.
AmiensAges 12 years+ - NCT05047133RecruitingPhase 2/Phase 3
Early TXA treatment for adult hip fracture surgery
This study tests whether giving a blood-clot-reducing medicine (TXA) early after an adult hip fracture helps reduce bleeding and related problems around surgery. It may help some patients getting operative fixation by improving safety during recovery.
Grand Blanc, MichiganAges 18 years+ - NCT05045664RecruitingPhase 3
New follicular lymphoma treated with radiation plus antibody
This trial studies whether adding a targeted antibody to standard radiation can help people with early-stage, newly diagnosed follicular lymphoma. It aims to control the lymphoma more effectively while keeping treatment safe.
BerlinAges 18 years+ - NCT04297085Recruiting
Study of why blood clots in veins come back
This study follows people who have had a vein blood clot (or related venous clot) to understand what factors may make the clot happen again. It may help clinicians find better ways to prevent repeat clots.
BrestAges Any age - NCT04365036RecruitingPhase 3
Check if PD-1 plus chemo-radiation helps early nasal lymphoma
This trial studies whether adding toripalimab (an immune therapy that targets PD-1) to standard chemo-radiation works better for newly diagnosed early-stage nasal natural killer/T-cell lymphoma. It’s designed to see if the combined treatment can improve outcomes while staying safe.
Guangzhou, GuangdongAges 18–75 - NCT05421416RecruitingPhase 2
Loratadine to prevent bone pain after stem cell transplant treatment
This trial tests loratadine (an allergy medicine) to see if it can prevent bone pain caused by a growth-factor injection used during lymphoma or multiple myeloma treatment. It may help reduce pain around the time you get that injection and your upcoming stem cell transplant.

Fecal transplant for gut graft-versus-host disease
This study tests whether restoring healthy gut bacteria using a fecal microbiota transplant can improve steroid-refractory gut graft-versus-host disease (aGvHD) after stem cell transplant. If your gut symptoms are your first episode and your stool bacteria diversity is low, this trial may be an option worth screening for.
