19(T2)28z1xx Chimeric Antigen Receptor (CAR) T Cells in People With B-Cell Cancers

August 24, 2026 updated by: Memorial Sloan Kettering Cancer Center

A Phase I Study of CD19-Targeted 19(T2)28z1xx Chimeric Antigen Receptor (CAR) Modified T Cells in Adult Patients With Relapsed or Refractory B-cell Malignancies

The purpose of this study is to test the safety of 19(T2)28z1xx CAR T cells in people with relapsed/refractory B-cell cancers. The researchers will try to find the highest dose of 19(T2)28z1xx CAR T cells that causes few or mild side effects in participants. Once they find this dose, they can test it in future participants to see if it is effective in treating their relapsed/refractory B-cell cell cancers. This study will also look at whether 19(T2)28z1xx CAR T cells work against participants' cancer.

  • Impaired cardiac function (LVEF <40%) as assessed by ECHO or MUGA scan.

  • Patients with the following cardiac conditions will be excluded:

    • New York Heart Association (NYHA) stage III or IV congestive heart failure
    • Myocardial infarction ≤6 months prior to enrollment
    • History of clinically significant ventricular arrhythmia or unexplained syncope, not believed to be vasovagal in nature or due to dehydration ≤6 months prior to enrollment
  • Patients with HIV or active hepatitis B or hepatitis C infection are ineligible.
  • Patients with prior allogeneic hematopoietic stem cell transplant are eligible, if more than 3 months from transplant and if patients have no active graft versus host disease (GvHD) and not on systemic immunosuppressive therapy.
  • Prior CD19-directed therapy including CD19 CAR T cells is allowed, as long as expression of CD19 is confirmed by flow cytometry or immunohistochemistry.
  • Patients with uncontrolled systemic fungal, bacterial, viral or other infection are ineligible.
  • Patients with any concurrent active malignancies as defined by malignancies requiring any therapy other than expectant observation or hormonal therapy, with the exception of squamous and basal cell carcinoma of the skin.
  • Patients with presence of clinically significant neurological disorders such as epilepsy, generalized seizure disorder, severe brain injuries are ineligible.
  • Any other issue which, in the opinion of the treating physician, would make the patient ineligible for the study.

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 19(T2)28z1xx CAR T cells
Cohorts of 3-6 patients will be infused with escalating doses of 19(T2)28z1XX CAR T cells to establish the RP2D. There are 4 planned flat-dose levels: 25x10^6, 50 x 10^6, 100 x 10^6 and 200 x 10^6 CAR T cells and one de-escalation dose: 12.5 x 10^6 CAR T cells. A standard 3+3 dose escalation design will be implemented starting from dose 1.
Drug: 19(T2)28z1xx CAR T cells
2-7 days following the completion of the conditioning chemotherapy, patients will receive the CAR- T cells by IV infusion over 1-3 days depending on the dose level and formulation of the final CAR- T cells.

What is the study measuring?

Primary Outcome Measures
