Campath/Fludarabine/Melphalan Transplant Conditioning for Non-Malignant Diseases

A Study of Hematopoietic Stem Cell Transplantation (HSCT) in Non-Malignant Disease Using a Reduced-Intensity Preparatory Regime


Sponsor

Washington University School of Medicine

Enrollment

220 participants

Start Date

Dec 1, 2001

Study Type

INTERVENTIONAL

Conditions

Summary

The hypothesis for this study is that a preparative regimen that maximizes host immunosuppression without myeloablation will be well tolerated and sufficient for engraftment of donor hematopoietic cells. It is also to determine major toxicities from these conditioning regimens, within the first 100 days after transplantation.


Eligibility

Max Age: 20 Years

Plain Language Summary

Simplified for easier understanding

This study tests a specific combination of conditioning drugs — Campath, Fludarabine, and Melphalan — given before bone marrow or cord blood transplants in children and young adults with non-cancerous blood and immune system disorders. The conditioning regimen prepares the body to accept donor cells. The study covers conditions like thalassemia, sickle cell disease, and other blood disorders. You may be eligible if: - You are under 21 years old - You have a non-cancerous blood or immune disorder (e.g., sickle cell disease, thalassemia, bone marrow failure) - You have a suitable bone marrow or cord blood donor available - Your organ function (lungs, kidneys, liver) meets the required health levels - You have a negative pregnancy test (if applicable) You may NOT be eligible if: - You are HIV-positive - You have an active invasive infection - You are pregnant or breastfeeding Talk to your doctor to see if this trial is right for you.
