Condition(s) targeted: Autoimmune Disorder

Intervention: anti-thymocyte globulin (Biological); carmustine (Drug); cytarabine (Drug); etoposide (Drug); melphalan (Drug); prednisone (Drug); autologous hematopoietic stem cell transplantation (Procedure); peripheral blood stem cell transplantation (Procedure); syngeneic bone marrow transplantation (Procedure); laboratory biomarker analysis (Other)

Summary

This phase II trial studies how well carmustine, etoposide, cytarabine and melphalan together with antithymocyte globulin before a peripheral blood stem cell transplant works in treating patients with severe autoimmune neurologic disease that did not respond to previous therapy. In autoimmune neurological diseases, the patient's own immune system 'attacks' the nervous system which might include the brain/spinal cord and/or the peripheral nerves. Giving high-dose chemotherapy, including carmustine, etoposide, cytarabine, melphalan, and antithymocyte globulin before a peripheral blood stem cell transplant weakens the immune system and may help stop the immune system from 'attacking' a patient's nervous system. When the patient's own (autologous) stem cells are infused into the patient they help the bone marrow make red blood cells, white blood cells, and platelets so the blood counts can improve

Clinical Details

Official title: High-Dose Immunosuppressive Therapy Using Carmustine, Etoposide, Cytarabine, and Melphalan (BEAM) + Thymoglobulin Followed by Syngeneic or Autologous Hematopoietic Cell Transplantation for Patients With Autoimmune Neurologic Diseases

Study design: Endpoint Classification: Safety Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Incidence of grades 4-5 regimen-related toxicity as assessed by the Regimen Related Toxicity Scale

Secondary outcome:

Disease responses as assessed by clinical, laboratory and radiologic evaluation

Transplant-related mortality (TRM)

Engraftment kinetics

Efficacy of peripheral blood stem cell (PBSC) mobilization from syngeneic donors and autograft recipients

Detailed description: PRIMARY OBJECTIVES:

I. Evaluate the safety of high-dose carmustine, etoposide, Ara-c (cytarabine) and melphalan (BEAM) and Thymoglobulin (antithymocyte globulin) as a high-dose immunosuppressive treatment (HDIT) regimen in patients with severe, refractory neurological autoimmune disease.

SECONDARY OBJECTIVES:

I. Evaluate disease responses and the duration of response to HDIT and autologous hematopoietic stem cell transplantation (HSCT).

II. Determine the efficacy and safety of G-CSF (filgrastim) and prednisone or cyclophosphamide for hematopoietic stem mobilization in patients with neurological autoimmune diseases.

OUTLINE:

Patients receive carmustine intravenously (IV) on day - 6, etoposide IV and cytarabine IV

twice daily (BID) on days - 5 to -2, melphalan IV on day -1, and antithymocyte globulin IV on

days - 2 and -1. Patients then undergo autologous or syngeneic peripheral blood stem cell

transplant on day 0. Patients also receive prednisone orally (PO) once daily (QD) on days 7-21, followed by 2 week taper.

After completion of study treatment, patients are followed up at 3 months, 1 year, and then annually thereafter for up to 5 years.
