Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the toxicity and feasibility of prophylactic administration of donor derived central memory T Cells after T cell depleted allo-SCT;Secondary Objective: - the determination of appearance or expansion of antigen specific T cells from donor-derived TCM during 36 weeks (9 months) after the first infusion of study medication. - the evaluation of the incidence of viremia and clinical manifestations of virus related organ manifestations (CMV, EBV, Adenovirus, HSV, VZV) - Clinical signs of viral infections - Incidence of relapse - Incidence of bacterial and fungal infections - Evaluate the effect on mixed bone marrow and/or peripheral blood chimerism ;Primary end point(s): Toxicity: Cumulative incidence of acute GVHD overall grade 3 or higher within three months after infusion of the last dose of TCM Feasibility: The proportion of donors who consent to an additional apheresis procedure, and the proportion of patients that are not excluded before the transfer of the first dose of TCM on day 30 +/- 5;Timepoint(s) of evaluation of this end point: Toxicity will be evaluted on an ongoing basis. In case of acute GVHD overall grade = III in 2 out of the first 3 evaluable patients, or 3 out of the first 6 patients, or 4 out of the first 10 patients, the study will be closed temporarily for inclusions and the outcomes in all patients will be presented to the DSMB in order to decide whether potential beneficial effects of the treatment could overcome non-beneficial effects of GVHD. Efficacy will be evaluted after first fifteen procedures to isolate TCM has taken place. If out of the first fifteen procedures to isolate TCM from non-mobilized apheresis products less than 6 result in an appropriate TCM cell product which can be given to the patient, the procedure is considered to be not feasible and the study will be stopped.

Secondary

MeasureTime frame
Secondary end point(s): - To determine the appearance or expansion of antigen specific T cells from donor-derived TCM during 36 weeks (9 months) after the infusion of study medication. - To evaluate the incidence of viremia and clinical manifestations of virus related organ manifestations (CMV, EBV, Adenovirus, HSV, VZV) - Clinical signs of viral infections - Incidence of relapse - Incidence of bacterial and fungal infections - Evaluate the effect on mixed bone marrow and/or peripheral blood chimerism ;Timepoint(s) of evaluation of this end point: Secondary objectives will be analyzed at the end of the trial
