Duarte, CaliforniaAges 18 years+ - NCT04897490Recruiting
Real-world study of ATO plus ATRA for adult acute APL
This study looks at how well first-time treatment with ATO plus ATRA works in adults with acute promyelocytic leukemia (APL). It mainly checks treatment results in real life, including whether patients reach “molecular remission” (very deep disease control).
La Plata, Buenos AiresAges 18 years+ - NCT04898790Recruiting
Testing ways to improve thinking after bone marrow transplant
This study looks at whether a physical activity program and related study measures can improve thinking and memory in older adults around the time of a stem cell transplant. If you qualify and participate, the team will compare outcomes between groups to see what approach works best.
Omaha, NebraskaAges 19 years+ - NCT04925349Recruiting
Study blood immune patterns in several rare brain diseases
This study looks at immune cells in blood to better understand rare brain conditions caused by genetic changes. It may help researchers understand why symptoms happen and how the immune system is involved.
Le Kremlin-BicêtreAges 1.3 years–60 years - NCT05018793RecruitingPhase 1
Testing stem cell injections for spinal cord injury safety
This early study tests whether two types of stem cells—made from your own fat cells versus from donated umbilical-cord cells—are safe when injected into the fluid around the spinal cord. It may help researchers find safer cell-based options for people with spinal cord injury.
St John'sAges Any age - NCT05149742Recruiting
Study of hearing loss and thinking skills in midlife adults
This study looks at how severe hearing loss affects thinking and memory in adults aged 45–64. Researchers will compare people with significant hearing loss to people with normal hearing who are similar in age, sex, and education.
ParisAges 45–64 - NCT05480644Recruiting
Blood biomarker study for brain tumor patients
This study collects blood (and looks at samples) from adults who have a confirmed brain tumor, either one that started in the brain or one that spread to the brain. The goal is to understand biomarkers—signals in the body—that may help improve diagnosis or tracking over time.
