简要总结
Eligible patients will receive escalating doses of 4G7-CARD T-cells paralleling clinical standard of care with unmanipulated donor lymphocytes. There are 3 intra-patient dose levels planned.
Patients will be followed up regularly during the interventional phase of the study until 12 months post-final 4G7-CARD T-cell infusion. Thereafter patients will be followed up annually for years 2 and 3.
详细描述
Patients will receive escalating doses of 4G7-CARD T-cells (after pre-conditioning with Fludarabine and Cyclophosphamide), paralleling clinical standard of care with unmanipulated donor lymphocytes. Intra-patient dose escalation will proceed at intervals of not less than 8 weeks, dependent on development of toxicity or evidence of efficacy and confirmation by the Trial Management Group.
Three dose cohorts levels are planned, and dosing will be according to total CD3+ T- cell dose as this correlates with toxicity in the unmanipualated donor lymphocyte setting:
- Dose Level 1: 1x10^6 CD3+ T-cells/kg (starting dose for all patients)
- Dose Level 2: 3x10^6 CD3+ T-cells/kg
- Dose Level 3: 1x10^7 CD3+ T-cells/kg
The inter-patient dosing for the first 3 patients was at least 28 days, following TMG confirmation.
Patients will be followed up regularly during the interventional phase of the study until 12 months post-final 4G7-CARD T-cell infusion. During the long term follow up phase of the study (years 2-3 post-final 4G7-CARD T-cell infusion) patients will be followed-up annually for overall survival, disease status and safety.

结局指标
主要结局
Maximum grade for each toxicity type as assessed by CTCAE v4.03, summarized as proportions.
时间窗: Up to 3 years post final 4G7-CARD T-cell infusion
Toxicity evaluation following 4G7-CARD T-cell administration as evaluated by the occurrence of adverse events per studied dose using CTCAE v4.03, defined as \>grade 2 events that are causally related to study treatment or procedure or Serious Adverse Reactions that require withdrawal of the patient from the study; development and severity of graft-versus-host-disease (GvHD) following cell infusion will also be evaluated as a potential toxicity, as well as development and severity of cytokine release syndrome / macrophage activation syndromes assessed by 'University of Pennsylvania' criteria
Feasibility of generation of 4G7-CARD T-cells using the ProdigyTM system
时间窗: Through patient registration and manufacturing period, an average of 18 months from start of trial
The number of ATIMP successfully manufactured would be assessed for all registered patients
次要结局
- Assessing the timing and magnitude of cytokine release, evaluated using Cytokine bead arrays(Sampling occurs at days 0, 4, 6, 11, 18, plus 1 month post final 4G7-CARD T-cell infusion)
- Assessment of engraftment, expansion and persistence of the 4G7-CARD T-cells as determined by quantitative polymerase chain reaction (qPCR) or flow cytometry(Sampling occurs at days 0, 4, 6, 11, 18, plus months 1, 2, 3, 6, 9 and 1 year post final 4G7-CARD T-cell infusion)
- Assessing the depletion of B cell compartment, as determined by flow cytometry(Sampling occurs at days 0, 4, 6, 11, 18, plus months 1, 2, 3, 6, 9 and 1 year post final 4G7-CARD T-cell infusion)
