CD19+ Malignancies: Relapse Post-allogeneic Transplant Clinical Trial
— CARDOfficial title:
Chimeric Antigen Receptor (CAR)19 Donor Lymphocytes for Relapsed Cluster of Differentiation (CD)19+ Malignancies Following Allogeneic Transplantation (CARD)

Health authority | |
Study type | Interventional |
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.

Primary | Feasibility of generation of 4G7-CARD T-cells using the ProdigyTM system | The number of ATIMP successfully manufactured would be assessed for all registered patients | Through patient registration and manufacturing period, an average of 18 months from start of trial | |
Primary | Maximum grade for each toxicity type as assessed by CTCAE v4.03, summarized as proportions. | 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 | Up to 3 years post final 4G7-CARD T-cell infusion | |
Secondary | Assessment of engraftment, expansion and persistence of the 4G7-CARD T-cells as determined by quantitative polymerase chain reaction (qPCR) or flow cytometry | Data for engraftment and expansion would be summarised by mean, median or interquartile ranges and a Kaplan Meier plot for persistence | 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 | |
Secondary | Assessing the depletion of B cell compartment, as determined by flow cytometry | Data would be summarised using means (medians) and as the percentage reduction from baseline | 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 | |
Secondary | Assessing the timing and magnitude of cytokine release, evaluated using Cytokine bead arrays | Data on timing (kinetic of change) and magnitude of cytokine levels can be summarised using means (medians) and plots for each patients | Sampling occurs at days 0, 4, 6, 11, 18, plus 1 month post final 4G7-CARD T-cell infusion |
