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

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.

Study Overview

• Status: Recruiting
• Conditions: Hemoglobinopathies; Metabolic Disorders; Hematologic, Immune, or Bone Marrow Disorders; Non-malignant Disorders
• Intervention / Treatment: Drug: Treatment Plan 1: Stratum 1; Drug: GVHD Regimen B: BM Recipients; Drug: Treatment Plan 2: Strata 2, 3, or 4; Drug: GVHD Regimen A: UCB Recipients

Detailed Description

The study uses reduced intensity conditioning that is immune suppressive to achieve donor cell engraftment without exposure to radiation or high dose chemotherapy in children with non-malignant disorders. The intent is to minimize early and late regimen related toxicities in the context of a reduced intensity regimen.

In addition to maximizing opportunity for donor cell engraftment, the trial seeks to minimize toxicities associated with transplant such as graft versus host disease and employs GVHD prophylaxis that seeks to decrease rates of acute and chronic GVHD in the setting of matched and mismatched donor stem cell transplants from marrow and cord blood sources.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Donor engraftment as measured by chimerism	Engraftment is measured in myeloid and lymphoid lineage cells	100 days post-transplant
Major toxicities as graded by the CTC v4	Toxicity monitoring includes unanticipated side effects (new) and all severe irreversible toxicities Grade 3 and above unexpected Grade 4 and above - all toxicities that are possibly, probably or definitely related to protocol therapy All deaths irrespective of attribution	100 days post-transplant

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Time to neutrophil and platelet engraftment as measured by complete blood counts	Defined as an ANC >500/microliter and platelets >20,000 or 50,000/microliter depending on disorder	Post transplant
Incidence of acute graft-versus-host disease as measured by protocol grading scale	aGVHD - involving the skin, gut and liver. Classified according to grading described by Thomas et al. NEJM 1975; 292:895-902	100 days post-transplant
Incidence of chronic graft-versus-host disease as measured by protocol grading scale	cGVHD classified per Schulman et al. Am J Med 69: 204-17, 1980.	2 years post-transplant
Long-term donor engraftment by donor chimerism	Donor chimerism is determined by PCR analysis after cell separation into lymphoid and myeloid lineage cells using antibodies. Can also be detected by FISH analysis in the event of donor and recipient sex discrepancy.	2 years post-transplant
Immune reconstitution by laboratory evaluations	Immune reconstitution detected by absolute numbers of T cell phenotypes, B cells and NK cells. T cell function determined by proliferative response to mitogens. B cell function determined by evaluating anti-tetanus antibody titers.	1 year post-transplant
Overall and disease free survival	Overall survival is defined as survival with or without disease Event free survival is defined as disease free, severe GVHD free survival, monitoring quality of life and relevant parameters.	2 years post-transplant
