NCT ID: NCT00010335

Last Updated: 2015-03-06

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 6 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2000-11-30
• Study Completion Date: 2011-05-31

Brief Summary

OBJECTIVES: I. Determine the safety and long term complications of total body irradiation in combination with cyclophosphamide, anti-thymocyte globulin, and autologous CD34-selected peripheral blood stem cell (PBSC) transplantation in children with refractory autoimmune disorders.

II. Determine the efficacy of this treatment regimen in these patients. III. Determine the reconstitution of immunity after autologous CD34-selected PBSC transplantation in these patients.

IV. Determine engraftment of autologous CD34-selected PBSC in these patients.

Detailed Description

PROTOCOL OUTLINE: This is a multicenter study. Patients receive filgrastim (G-CSF) subcutaneously daily until peripheral blood stem cell (PBSC) collection is completed. CD34+ cells are separated from the rest of the PBSCs.

Patients undergo total body irradiation twice daily on days -5 and -4. Patients receive anti-thymocyte globulin IV on days -5, -3, -1, 1, 3, and 5 and cyclophosphamide IV on days -3 and -2. CD34-selected PBSCs are reinfused on day 0. Patients receive G-CSF IV daily beginning on day 0 and continuing until blood counts recover.

Patients are followed annually for 5 years and then every 5 years thereafter.

Eligibility Criteria

Inclusion Criteria

PROTOCOL ENTRY CRITERIA:

• Refractory to standard or aggressive therapy OR unacceptable toxicity from standard therapy
• Reasonable expectation of possible improvement as evidenced by a good potential for rehabilitation therapy and adequate social factors
• No serious CNS damage that would preclude significant functional recovery

--Prior/Concurrent Therapy--

• Chemotherapy: At least 4 weeks since prior methotrexate or cyclophosphamide
• Endocrine therapy: At least 4 weeks since prior intra-arterial steroids Juvenile rheumatoid arthritis patients should continue steroids without taper throughout mobilization and harvest of stem cells If receiving corticosteroids, must be continued without taper

Other:

• At least 4 weeks since prior anti-inflammatory agents such as non-steroidal anti-inflammatory drugs (NSAIDs) or sulfasalazine
• At least 4 weeks since prior cyclosporine, tacrolimus, mycophenolate mofetil, azathioprine, penicillamine, or etanercept

--Patient Characteristics--

• Life expectancy: At least 30 days
• Hematopoietic: Absolute neutrophil count at least 1,000/mm3 OR Platelet count at least 100,000/mm3 No bone marrow aspirate or biopsy consistent with production defect (depletion of neutrophil precursors or megakaryocytes) No myelodysplasia
• Hepatic: Bilirubin no greater than 2.5 mg/dL AST no greater than 300 U/L on two sequential tests No severe liver dysfunction within past month No active hepatitis A, B, or C
