Non-Ablative Allo HSCT For Hematologic Malignancies or SAA

• Status: Completed
• Trial end date: 2011-10-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy used to kill cancer cells.

PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by peripheral stem cell transplantation in treating patients who have hematologic cancer or aplastic anemia.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Case Comprehensive Cancer Center
• Collaborator: National Cancer Institute (NCI)
• Treatments: Antilymphocyte Serum; Cyclophosphamide; Fludarabine; Fludarabine phosphate

Criteria

DISEASE CHARACTERISTICS:

• Histologically proven high-risk hematologic malignancy

• Acute non-lymphocytic leukemia (ANLL) after induction failure, or in first complete remission (CR) with high-risk features, including any of the following:

• Stem cell or biphenotypic classification (AML-M0)

• Erythroleukemia (AML-M6)

• Acute megakaryocytic leukemia (AML-M7)

• Cytogenetic markers indicative of poor prognosis

• Failure to achieve CR after standard induction therapy

• Acute lymphocytic leukemia (ALL) or ANLL in relapse or second or subsequent remission

• Chronic myelogenous leukemia (CML) in chronic or accelerated phase

• Patients with CML in blast crisis are eligible after reinduction chemotherapy places them in chronic phase

• High-risk ALL in first CR with high risk defined by presence of t(4;11), t(9;22) translocation, hyperleukocytosis (initial WBC greater than 30,000/mm^3), or failure to achieve CR by day 28 after standard induction

• No T-cell ALL or t(8;14) positive B-cell ALL in first remission with hyperleukocytosis

• Myelodysplastic syndrome by peripheral blood smear and bone marrow examination

• Refractory to medical management OR

• Cytogenetic abnormalities predictive of transformation into acute leukemia including 5q-, 7q-, monosomy 7, and trisomy 8 OR

• Evidence of evolution to AML (e.g., refractory anemia with excess blasts (RAEB) or RAEB in transformation)

• Multiple myeloma, non-Hodgkin's lymphoma (NHL), ANLL, or ALL with recurrent disease after autologous stem cell transplantation (SCT)

• At least 3 months since prior autologous SCT

• Hodgkin's lymphoma, NHL, or multiple myeloma beyond first CR or primary induction failures whose disease has demonstrated sensitivity to pre-transplantation cytoreduction (defined as greater than 50% reduction in tumor burden)

• Mantle zone NHL allowed after induction therapy

• Myeloproliferative disorder that is non-responsive to medical management and requires allografting, unless evidence of grade 3 or worse myelofibrosis on marrow biopsy OR

• Histologically proven acquired severe aplastic anemia (SAA) that is recurrent or unresponsive after anti-thymocyte globulin and/or cyclosporine

• SAA defined by at least 2 of the following conditions:

• Granulocyte count less than 500/mm^3

• Platelet count less than 20,000/mm^3

• Absolute reticulocyte count less than 20,000/mm^3 after correction for hematocrit

• Ineligible for full ablative conditioning due to any of the following conditions:

• Prior extensive therapy (more than 2 salvage chemotherapy regimens and/or autologous transplantation)

• Over age 55 OR

• Under age 55 with comorbid disease (e.g., suboptimal cardiac, pulmonary, or renal function and/or prior life-threatening infection)

• HLA-A, B, and DR phenotypically identical sibling donor OR

• HLA-A, B, and DR identical genetically matched unrelated donor

• No ANLL in first CR (less than 5% blasts in marrow) with translocations t(8;21) and inv(16) unless failed first-line induction therapy OR

• No ANLL in first CR (less than 5% blasts in marrow) with translocations t(15;17) abnormality unless failed first-line induction therapy OR molecular evidence of persistent disease

• No active CNS disease
