Study Details

Study Description

Brief Summary

The purpose of this clinical trial is to examine safety and toxicity of CD45RA depleted donor lymphocyte infusion (DLI) after transplantation of TCRα/β/CD19 depleted peripheral blood stem cells.

Condition or Disease Intervention/Treatment Phase
  • Biological: CD45RA depleted donor lymphocyte infusion (DLI)
Phase 1/Phase 2

Detailed Description

Patients will undergo routine reduced intensity conditioning regimen and intravenous infusion of T-cell receptor alpha/beta (TCRα/β)/CD19 depleted peripheral blood stem cells (not content of clinical trial).

If no graft-versus-host disease (GVHD) occurs, patients receive the trial-related memory T cell donor lymphocyte infusion (DLI) on Day 30 after transplantation.

In a dose finding part (phase I) escalating doses will be applied in cohorts of three (three plus three design) patients with a maximum of 18 patients for three dose levels (dose level 1-3). A fourth lower dose level (dose level 0) is started, if >=2 out of 6 patients with dose level 1 develop aGVHD III/IV. The maximum tolerated dose (MTD) will be used for the confirmatory part (phase II) of the study.

Outcome Measures

Primary Outcome Measures

  1. Phase I, dose escalation [100 days]

    Safety and toxicity of CD45RA depleted DLI as defined by infusional toxicities and acute GVHD grad III-IV.

  2. Phase II, extension phase [100 days]

    Acute graft-versus-host disease grade III-IV defined as GVHD occurring within 100 days after HCT
