MCL cells are malignant B cells that express antigens, such as CD193,4

  • CD19 is a cell-surface protein that regulates the immune response5
  • CD19 is only expressed in B cells, and is expressed across the B-cell lineage, including the abnormal naïve B cells associated with MCL4-6
  • The moderate-to-high expression of CD19 in MCL, and its lack of expression in essential tissues, make CD19 an attractive therapeutic target4,5

TECARTUS mechanism of action: single-infusion, autologous cellular therapy designed for R/R MCL, a CD19-expressing B-cell malignancy with a high circulating tumor burden1,2,7,8

TECARTUS™ mechanism of action
  1. Target Binding Domain—binds to CD19 on the surface of B cells1,9

  2. CD28 Co-stimulatory Domain

    • CD28, the co-stimulatory domain in TECARTUS, augments T-cell receptor signaling to drive cytokine production and T-cell proliferation1,9
  3. CD3-ζ Activation Domain—activates T cell1,9

TECARTUS binds to CD19-expressing cancer cells and normal B cells1

  • Upon engagement with target cells, the co-stimulatory domains activate downstream signaling cascades that result in
    • T cell activation, proliferation, and acquisition of effector functions
    • Secretion of inflammatory cytokines and chemokines
  • This sequence of events leads to killing of CD19-expressing cells

TECARTUS manufacturing process: successfully and reliably manufactured for patients with R/R MCL1

MEDIAN 15-day TURNAROUND TIME from leukapheresis
to product delivery
(range 11 to 28 days)



*In the ZUMA-2 trial, 3 patients did not receive TECARTUS due to manufacturing failure.1

MCL=mantle cell lymphoma; R/R=relapsed or refractory.
