|Official Title:||Multicenter, Open-label, Adaptive Design Phase I Trial With Genetically Modified T-cells Carrying Universal Chimeric Antigen Receptors (UniCAR02-T) in Combination With CD123 Target Module (TM123) for the Treatment of Patients With Hematologic and Lymphatic Malignancies Positive for CD123|
|Actual Study Start Date :||January 28, 2020|
|Estimated Primary Completion Date :||February 2022|
|Estimated Study Completion Date :||April 2022|
Preconditioning (lymphodepletion) with cyclophosphamide and fludarabine, followed by combination treatment of genetically modified T-cells carrying universal chimeric antigen receptors (UniCAR02-T) with the recombinant antibody derivative TM123.
Drug: Cyclophosphamide (Non-IMP)
Intravenous infusion for 3 days
Drug: Fludarabine (Non-IMP)
Intravenous infusion for 3 days
Drug: TM123 (IMP)
Intravenous Infusion for 25 days
Drug: UniCAR02-T (IMP)
Intravenous infusion of single dose
- Safety and tolerability [ Time Frame: DLT period (infusion period of TM123 + 7 days or + 28 days in patients with complete blast clearance) until Safety Follow-up 1 (infusion period of TM123 + 28 days + 3 months) ]Incidence and intensity of adverse events graded according to CTCAE V5.0
- Incidence of dose limiting toxicity (DLT) [ Time Frame: DLT period (infusion period of TM123 + 7 days or + 28 days in patients with complete blast clearance) ]DLT is defined as any adverse Event at least possible related to TM123 and/or UniCAR02-T
- Maximum tolerated dose (MTD) [ Time Frame: DLT period (infusion period of TM123 + 7 days or + 28 days in patients with complete blast clearance) ]The dose for which the isotonic estimate of the DLT probability is closest to the target DLT probability of 0.2.
- Recommended phase 2 dose (RP2D) [ Time Frame: DLT period (infusion period of TM123 + 7 days or + 28 days in patients with complete blast clearance) ]The RP2D will be determined based on MTD, all available efficacy data, and all available safety data, including information derived from additional treatment cycles.
- Complete remission (CR), incomplete remission (CRi) and partial remission (PR) [ Time Frame: until fifteen years after last UniCAR02-T administration ]
CR: Bone marrow blasts < 5%, absence of extramedullary disease, absolute neutrophil count > 1 Gpt/L and platelet count > 100 Gpt/L. Level of MRD should be measured in patients achieving CR in case as suitable marker exists.
CRi: All criteria for CR except residual thrombocytopenia (platelets < 100 Gpt/L) and/or neutropenia (absolute neutrophil count < 1 Gpt/L).
PR: All hematological criteria for CR with bone marrow blasts 5-25% and decrease of pre-treatment bone marrow blast percentage by at least 50 %.
- Disease stabilization (DS) [ Time Frame: until fifteen years after last UniCAR02-T administration ]Reduction of blast percentage by 25% compared to baseline without normalization of peripheral blood counts to levels not qualifying for PR or CR.
- Best response rate [ Time Frame: until fifteen years after last UniCAR02-T administration ]The best observed response during observational period. Response states are ordered descending as follows: CR > CRi > PR > DS > refractory disease.
- Progression free survival (PFS) [ Time Frame: until fifteen years after last UniCAR02-T administration ]The time from first treatment with TM123 and UniCAR02-T until disease progression or death. If no progress of death was observed during the observational period, the patient's progression free survival time will be censored on the date the patient was last seen progression-free and alive.
- Overall survival (OS) [ Time Frame: until fifteen years after last UniCAR02-T administration ]The number of days between the first study drug administration and death from any cause. If death was not observed during the observational period, the patient's overall survival time will be censored on the date the patient was last seen alive.
