NCT05707273

Brief Summary

This phase I trial tests the safety, side effects, and best dose of autologous anti-CD19 CAR-expressing T lymphocytes (CD19-CAR T cells) in older adults with B-cell acute lymphoblastic leukemia. Chimeric antigen receptor (CAR) T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of B-cell acute lymphoblastic leukemia.

Outcome Measures

Primary Outcomes (2)

  • Incidence of dose-limiting toxicity (DLT)

    Assessed using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Observed toxicities will be summarized in terms of type (organ affected or laboratory determination), severity, attribution, time of onset, duration, and reversibility or outcome.

    Up to 28 days after CD19-chimeric antigen receptor (CAR) T cell infusion

  • Incidence of adverse events

    Assessed using CTCAE version 5.0. Cytokine release syndrome adverse events will be characterized using the descriptions and grading scales found in the Lee, et. al. publication: 'ASTCT Consensus Grading for Cytokine Release Syndrome and Neurologic Toxicity Associated with Immune Effector Cells. Observed toxicities will be summarized in terms of type (organ affected or laboratory determination), severity, attribution, time of onset, duration, and reversibility or outcome.

    Up to 15 years

Secondary Outcomes (6)

  • Percentage of consented older B-acute lymphoblastic leukemia (ALL) patients undergoing leukapheresis who get sufficient CD19-CAR T cells manufactured and infused at their assigned dose level

    At T cell infusion (Day 0)

  • Minimal residual disease (MRD) response rate

    Up to 12 months post T cell infusion

  • Event-free survival

    From the start of CD19-CAR T cell infusion to the date of death or disease progression/relapse, whichever occurring first, assessed up to 15 years

  • Overall survival rate

    From start of protocol therapy to death, or last follow-up, whichever comes first, assessed up to 15 years

  • Rate of relapse, including MRD and extramedullary relapse

    Up to 2 years post treatment

  • +1 more secondary outcomes

  • Note: For research participants who do not speak English, a short form consent may be used with a City of Hope (COH) certified interpreter/translator to proceed with screening and leukapheresis, while the request for a translated full consent is processed. However, the research participant is allowed to proceed with lymphodepletion and T cell infusion only after the translated full consent form is signed
