The extracellular domain that we will use corresponds to the mouse monoclonal antibody that recognizes human CD19 from tisagenlecleucel®. It is feasible to develop a huCART-19 with research grade in Mexico, the next step is to evaluate its function in a clinical model.

We conducted a phase 1 clinical trial of anti-BCMA CAR T cells (CART-BCMA) with or without anti-CD19 CAR T cells (huCART19) in multiple myeloma (MM) patients responding to third- or later- line therapy (Phase A, N=10) or high-risk patients responding to first-line therapy (Phase B, N=20), followed by early lenalidomide or pomalidomide maintenance. Outcomes with CART-BCMA + huCART19 were similar to CART-BCMA alone. Collectively, our results demonstrate favorable safety, pharmacokinetics, and antimyeloma activity of dual-target CAR T cell therapy in early lines of multiple myeloma treatment.

CTL019/huCART19/tisagenlecleucel are effective at achieving durable remissions across cytogenetic categories. Relapsed/refractory patients with high-risk cytogenetics, including KMT2A-rearranged infant ALL, demonstrated high RFS and OS probabilities at 2 years.

Methods : Adult patients with r/r ALL were co-administered two humanized autologous CAR T cell products, one targeted to CD19 (huCART19) and the other to CD22 (CART22-65s) after fludarabine and cyclophosphamide lymphodepletion... Of 13 treated patients (median age 46 (range 28-71)), two had received prior murine CART19 cells, 8 had prior blinatumomab, 8 had prior inotuzumab and 10 had a prior allogeneic stem cell transplant (SCT)...This syndrome was refractory to IL6 and IL1beta inhibition but ultimately responded to ruxolitinib... Co-administration and adaptive dosing of CART22-65s with huCART19 in adult patients with r/r ALL is feasible and effective. The two different products demonstrated differential expansion and persistence kinetics. Despite prior exposure to CD19- and/or CD22-specific immunotherapies, all evaluable patients achieved CR with uMRD; we continue to monitor CAR T cell persistence and its impact on durability of response.

Reinfusion of CTL019/tisagenlecleucel or huCART19 is safe, may prolong B-cell aplasia in patients with short CAR persistence and reduce relapse risk, and can induce remissions in patients with CD19+ relapsed disease. Thus, reinfusion may provide an alternative to HSCT for short persistence. However, reinfusion is not effective for patients with nonresponse to initial CAR infusion.

Tisagenlecleucel and huCART19 are active at clearing CNS disease and maintaining durable remissions in children and young adults with CNS relapsed or refractory B-cell acute lymphocytic leukaemia or lymphocytic lymphoma, without increasing the risk of severe neurotoxicity; although care should be taken in the timing of therapy and disease control to mitigate this risk. These preliminary findings support the use of these CAR T-cell therapies for patients with CNS relapsed or refractory B-cell acute lymphocytic leukaemia.

HuCART19 achieved durable remissions with long-term persistence in children and young adults with relapsed or refractory B-ALL, including after failure of prior CAR T-cell therapy.
