Summary
This trial is studying a new way of doing an HCT: using drugs to lower the activity of the body's immune system before transplanting healthy stem cells to replace diseased or damaged cells.
Who is the study for?
This trial is for people aged 12-35 with sickle cell disease or β-thalassemia who need a stem cell transplant. They must have had certain complications like stroke, organ damage, or frequent pain episodes and agree to use contraception. Excluded are those over age 50, with recent strokes, uncontrolled infections, liver issues, HIV/hepatitis B/C, pregnancy, obesity (BMI >40), prior transplants or other cancers.
What is being tested?
The study tests if immune suppression drugs like fludarabine and dexamethasone before standard therapy can prevent graft failure and GvHD in patients receiving stem cell transplants. Other drugs may be added based on blood test results to improve immune suppression.
What are the potential side effects?
Possible side effects include weakened immunity leading to infections; reactions related to infusion; potential damage to organs such as the liver and kidneys; blood disorders; nausea; hair loss from chemotherapy agents used.
