Abstract

Chimeric antigen receptor-modified T cells with specificity for CD19 have shown promise in the treatment of chronic lymphocytic leukemia (CLL). It remains to be established whether chimeric antigen receptor T cells have clinical activity in acute lymphoblastic leukemia (ALL). Two children with relapsed and refractory pre-B-cell ALL received infusions of T cells transduced with anti-CD19 antibody and a T-cell signaling molecule (CTL019 chimeric antigen receptor T cells), at a dose of 1.4×10(6) to 1.2×10(7) CTL019 cells per kilogram of body weight. In both patients, CTL019 T cells expanded to a level that was more than 1000 times as high as the initial engraftment level, and the cells were identified in bone marrow. In addition, the chimeric antigen receptor T cells were observed in the cerebrospinal fluid (CSF), where they persisted at high levels for at least 6 months. Eight grade 3 or 4 adverse events were noted. The cytokine-release syndrome and B-cell aplasia developed in both patients. In one child, the cytokine-release syndrome was severe; cytokine blockade with etanercept and tocilizumab was effective in reversing the syndrome and did not prevent expansion of chimeric antigen receptor T cells or reduce antileukemic efficacy. Complete remission was observed in both patients and is ongoing in one patient at 11 months after treatment. The other patient had a relapse, with blast cells that no longer expressed CD19, approximately 2 months after treatment. Chimeric antigen receptor-modified T cells are capable of killing even aggressive, treatment-refractory acute leukemia cells in vivo. The emergence of tumor cells that no longer express the target indicates a need to target other molecules in addition to CD19 in some patients with ALL.

  • All approved CAR T-cell products are second-generation CARs that incorporate CD28 or CD137 (4-1BB) co-stimulatory signals.

    “All approved CAR T-cell products are second-generation CARs that incorporate CD28 or CD137 (4-1BB) co-stimulatory signals, which are essential for eliciting effector and memory cell expansion and persistence and a clinically relevant immune response (9-15).”

    From Scalable Manufacturing of CAR T Cells for Cancer Immunotherapy (2021) · cites this paper as [9]

    The paper states that the CTL019 receptor includes a CD137 (4-1BB) signaling domain, and the Results report substantial expansion of CTL019 cells in two children. It does not establish that all approved CAR T-cell products are second-generation CARs or that they all incorporate CD28 or CD137; the Methods describe this as a phase 1 trial, not a survey of approved products. No page numbers are available in our copy. (LLM, conf=0.88)

  • Most clinical protocols and all commercially approved therapies have relied on viral vectors to deliver CAR transgenes into T cells.

    “Further, most clinical protocols, and all the commercially approved therapies, have relied on viral vectors to deliver CAR transgenes into T cells (9-14,24-26).”

    From Scalable Manufacturing of CAR T Cells for Cancer Immunotherapy (2021) · cites this paper as [9]

    The Methods describe this clinical protocol as using a lentiviral vector, and the Abstract says CTL019 was expressed using lentiviral-vector technology. This supports the paper as an example of a clinical protocol using a viral vector, but it does not establish that most protocols or all commercially approved therapies use viral vectors. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Most CAR T cell trials to date have used autologous peripheral blood and apheresis as the main cell sources for manufacturing.

    “First, most CAR T cell trials to date have used autologous peripheral blood and apheresis as the main cell sources for manufacturing (9-18,21,22).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
