The autologous anti-CD19 CAR T-cell
therapy, TECARTUS®, is individually
prepared from each patient’s
T-cells in a 6-step process2:

Patient receiving infusion.

Leukapheresis

Obtain peripheral blood mononuclear cells

T cells.

Selection

Isolate T-cells to reduce the
likelihood that circulating tumor
cells drive the exhaustion of
CAR T-cells

anti­-CD3 and anti-­CD28 antibodies + IL-­2.

Activation

Activate T-cells using anti-CD3 and
anti-CD28 antibodies + IL-2

Anti­-CD19 CAR transgene.

Transduction

Insert anti-CD19
CAR transgene

CAR T­-cell expansion.

T-cell Expansion

In cell culture, expand the number of
CAR T-cells to achieve dose

CAR T cells in suspension for infusion.

Suspension

Formulate CAR T-cells into
suspension for infusion

ALL=acute lymphoblastic leukemia; CAR=chimeric antigen receptor; CD=cluster of differentiation; IL-2=interleukin-2.
