    Study Notes

    CAR T-cell Therapy in Childhood Leukemia

    • First child with acute lymphoblastic leukemia (ALL) treated with anti-CD19 CAR T-cells in April 2012
    • Experienced a life-threatening cytokine-release syndrome (CRS)
    • Remarkable recovery and ongoing remission for over 6 years
    • Demonstrated potential for durable remission in CAR T-cell therapy
    • Early phase trials showed unprecedented success in treating relapsed and/or refractory CD19-expressing B-cell malignancies
    • Many patients achieved long-term remission, potentially cure
    • FDA approved two anti-CD19 CAR T-cell products for B-cell ALL and diffuse large B-cell lymphoma
    • Revolutionized anticancer immunotherapy
    • More than 100 global trials are ongoing using CAR T-cells targeting antigens other than CD19

    Types of Leukemia and Lymphoma Treated

    • Acute lymphoblastic leukemia (ALL): Targeted in the first child trial and now with FDA-approved treatments
    • Chronic lymphocytic leukemia (CLL): Treated previously in adults
    • Follicular lymphoma: Successes initially seen in adult trials
    • Diffuse large B-cell lymphoma Now also treated with FDA-approved CAR T-cell products
