Design outcomes

Primary

MeasureTime frame
Main Objective: Phase I, Dose escalation - Determination of the maximum tolerated dose (MTD) of FBTA05 in combination with DLI in patients with CLL/low grade NHL and high grade NHL. Phase II, Efficacy - Evaluation of preliminary efficacy of FBTA05 in combination with DLI in patients with CLL/low grade NHL and high grade NHL with regard to objective response rates (CR, PR, SD).;Secondary Objective: Evaluation of safety and pharmacodynamic relationship of FBTA05 in context with DLI, the induction of cellular immunity in terms of Graft vs. Leukemia / Lymphoma effects (GvL) or Graft vs. Host disease (GvHD) and the determination of further efficacy data in terms of time to progression (TTP), duration of response and clinical benefit.;Primary end point(s): Phase I, Dose escalation - Determination of the maximum tolerated dose (MTD) of FBTA05 in combination with DLI in patients with CLL/low grade NHL and high grade NHL. Phase II, Efficacy - Evaluation of preliminary efficacy of FBTA05 in combination with DLI in patients with CLL/low grade NHL and high grade NHL with regard to objective response rates (CR, PR, SD).
