Cytokine Induced Killer (CIK) Cells In Leukemia Patients

Overview

The purpose of the Phase IIA study are to: 1. define the safety profile 2. evaluate the efficacy of a sequential infusion of unmanipulated Donor Lymphocyte Infusions (DLI) and Cytokine Induced Killer (CIK) cells for the treatment of molecular, cytogenetic or hematologic relapse after hematopoietic stem cell transplantation and The progression free survival and the overall survival after the sequential infusion of Donor Lymphocyte Infusions (DLI) and Cytokine Induced Killer(CIK) cells.

Detailed Description

This study is an open-label, multicenter, exploratory phase IIA study to evaluate the safety (dose-finding) and efficacy of a sequential administration of donor derived unmanipulated DLI and in vitro expanded Cytokine Induced Killer(CIK) cells. Two infusions of unmanipulated donor lymphocytes (1×106/Kg each) will be given with a minimum interval of 3 weeks. Three infusions of donor Cytokine Induced Killer (CIK) cells will be administered according to a dose escalating program, starting 3 weeks after second Donor Lymphocyte Infusions (DLI). In presence of grade 2 or more acute graft versus host disease(GVHD), the patient will not receive the next scheduled infusion. Only grade 4 acute graft versus host disease (aGVHD) is considered for the dose limiting toxicity (DLT). Once identified the maximally tolerated dose (MTD), this same combination of doses will be administered up to 24 patients in a two-stage minimax design. Primary Endpoints The primary endpoints of the Phase IIA study are: 1. the Maximally Tolerated Dose (MTD) – (safety end-point) 2. the cumulative incidence of molecular, karyotypic or haematologic responses at day +100 after the end of the cell therapy program – (efficacy end-point) Secondary Endpoints Progression Free Survival (PFS) Progression Free Survival (PFS) will be defined as any evidence of molecular, cytogenetic or haematologic disease progression. Cytogenetic and/or molecular relapse will be defined where available as any evidence of a pre-transplant defined abnormality using conventional cytogenetics or FISH techniques or molecular probes. Assessments will be performed at 1 year after the end of the cell therapy program Overall Survival (OS) The Overall Survival(OS) will be assessed by 1 year after the end of the cell therapy program. For assessment of the Overall Survival (OS), events will be deaths for any causes, patients being censored if alive.

Interventions

  • Biological: in vitro expanded Cytokine Induced Killer (CIK) cells
    • Three infusions of donor Cytokine Induced Killer (CIK) cells will be administered according to a dose escalating program, starting 3 weeks after second Donor Lymphocyte Infusions (DLI). Cytokine Induced Killer administrations will be separated by 3 weeks intervals

Arms, Groups and Cohorts

  • Experimental: Cytokine Induced Killer
    • Sequential Infusion of Unmanipulated Donor Lymphocytes and Cytokine Induced Killer (CIK)

Clinical Trial Outcome Measures

Primary Measures

  • Safety Measures
    • Time Frame: Clinical response was measured at 100 days after the completion of the cell therapy program.
    • The occurrence of a grade 4 acute graft versus host disease (GVHD), judged to be related to the study medication. Grading and staging will be performed using the Glucksberg scale

Secondary Measures

  • Efficacy Measures
    • Time Frame: The clinical response will be registered at day +100 after the last Cytokine Induced Killer (CIK) cell infusion
    • The proportion of patients achieving a complete, a partial or a hematologic improvement in responses to the experimental infusion of cytokine induced killer (CIK)cells
