CotonouAges Any age - NCT07163728Recruiting
Leptin as a marker for chemo sensitivity in new AML
This study is looking at a substance called leptin in the blood of people with newly diagnosed acute myeloid leukemia (AML). The goal is to see if leptin levels can help doctors predict how well chemotherapy will work, which could guide better treatment choices.
Fuzhou, FujianAges 18 years+ - NCT02161783Recruiting
Second transplant for blood stem cell graft failure
This trial studies treatment after a first stem cell transplant fails to produce lasting blood recovery. It may help people who need a second transplant because their counts never fully recovered or then dropped again.
Minneapolis, MinnesotaAges Any age - NCT02869516Recruiting
Acute leukemia patient database study
This study enrolls people who have been diagnosed with acute leukemia and collects health information in a database. It may help doctors better understand care outcomes and improve future treatment planning.
Marseille, Bouches-du RhôneAges 18 years+ - NCT03529617Recruiting
Study of how a liposomal antifungal behaves in sick patients
This trial studies how liposomal amphotericin B (a drug used to treat serious fungal infections) moves through the body in people who are critically ill versus those who are not. It may help doctors choose safer and more accurate dosing for patients with blood-related illnesses.
LeuvenAges 18 years+ - NCT03125707Recruiting
Registry for adults with certain BCR-ABL1–negative blood cancers
This study keeps a patient registry to collect information about people with specific myeloid blood neoplasms (a type of blood cancer). It helps researchers understand these conditions over time and may improve how patients are cared for in the future.
AugsburgAges 18 years+ - NCT03598361Recruiting
Study of mineral levels in early pregnancy
This study looks at mineral (micronutrient) levels in women during early pregnancy to understand how minerals change in the body. It may help researchers learn whether mineral status is linked to healthy pregnancy outcomes.
PoznanAges Any age - NCT06208267Recruiting
Tranexamic acid for pain and bleeding after hip or knee replacement
This study tests whether a medicine called tranexamic acid (TXA) can reduce pain, improve movement, and lessen bleeding after hip or knee replacement surgery. It is for adults having their first joint replacement at St. Mary's Hospital.
Montreal, QuebecAges 18 years+ - NCT06192992Recruiting
Blood Flow Changes During Leg Heating
This study looks at how blood flow in your legs changes when they are gently heated. It helps researchers understand normal body responses and may guide future treatments for circulation problems.
San Diego, CaliforniaAges 18–65 - NCT06196203RecruitingPhase 2
Study of AK117 with Azacitidine for High-Risk MDS
This trial tests a new drug, AK117, combined with azacitidine for people newly diagnosed with high-risk myelodysplastic syndromes (MDS), a blood disorder. The goal is to see if the combination can help improve outcomes.
