Post-transplant Autologous Cytokine-induced Killer (CIK) Cells for Treatment of High Risk Hematologic Malignancies
- Conditions

- Registration Number
- NCT00477035
- Lead Sponsor
- Sally Arai
- Brief Summary
The purpose of the study is to conduct a phase I study of adoptive immunotherapy with autologous, ex-vivo expanded cytokine-induced killer (CIK) cells to reduce the relapse rate in autologous stem cell transplant patients with high-risk hematologic malignancies.
- Detailed Description
Disease relapse remains the major cause of treatment failure in autologous stem cell transplantation for patients with high-risk disease. Relapse after autologous transplant is in part due to the persistence of residual cancer cells. Cellular immunotherapy using activated autologous effector cells to recognize and kill tumor targets in a minimal disease state after transplant is a strategy being explored to reduce relapse and improve survival. We hypothesize that cytokine-induced killer (CIK) cell-based immunotherapy can reduce the relapse rate after high-risk autologous stem cell transplantation by treating post-transplant minimal residual disease.

Patients between 18 and 75 years of age, inclusive candidates for standard autologous SCT who are at high risk for relapse:
- Acute myelogenous leukemia (AML), high risk, in CR1 or beyond without a donor (CR1 defined as: normal bone marrow morphology, resolution of any previously abnormal karyotype, neutrophils > 1000/ul, platelets > 100,000/ul, independence from red cell transfusion, no evidence extramedullary leukemia)
- Hodgkin's lymphoma relapsed or refractory, with the presence of >= 1 adverse risk factor (Adverse risk factors are defined as stage IV involvement of the lung or bone marrow, constitutional symptoms, and the presence of more than minimal residual disease before the preparatory regimen)
- Multiple myeloma with high risk features with only single autologous transplant option. High risk features defined as IgA myeloma, B2M > 2.5 mg/ml with normal kidney function, complex karyotypes or isolated chromosome 13 abnormalities, standard-dose therapy > 12 months, or inability to achieve at least 50% reduction of plasma cells in the bone marrow or 50% reduction in the paraprotein concentration after initial induction chemotherapy prior to transplant.
