Genetically Engineered Cells (DuoCAR20.19.22-D95) for the Treatment of Relapsed or Refractory B-Cell Cancers
This phase I trial that tests the safety, side effects and best dose of DuoCAR20.19.22-D95 and how well it works in treating patients with B-cell cancers that have come back after a period of improvement (relapsed) or that have not responded to previous treatment (refractory). 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, such as CD19, CD20, and CD22, on the patient’s cancer cells is added to the T cells in the laboratory. The special receptor is called a CAR. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Giving chemotherapy, such as fludarabine and cyclophosphamide, before a CAR T-cell infusion helps lower the activity of the T cells in the body and prepares the body to receive the new T cells. DuoCAR20.19.22-D95 may be safe, tolerable, and/or effective in treating patients with relapsed or refractory B-cell cancers.

OUTLINE: This is a dose-escalation study of DuoCAR20.19.22-D95.
Patients undergo leukapheresis over 1.5-3 hours per standard practice. Patients receive fludarabine intravenously (IV) on days -6 to -3, cyclophosphamide IV on days -4 and -3, and DuoCAR20.19.22-D95 IV over 10-20 minutes on day 0 in the absence of disease progression or unacceptable toxicity. Patients also undergo echocardiography (ECHO) at screening and blood sample collection, bone marrow aspiration and biopsy, and computed tomography (CT), positron emission tomography (PET), and/or magnetic resonance imaging (MRI) throughout the study. Patients with lymphoma may undergo lymph node biopsy at screening. Additionally, patients may also undergo lumbar puncture at screening and may be repeated at day 28 and at relapse.
After completion of study treatment, patients are followed up at days 30, 60, 90 and months 6, 9, 12 and 24 then every 6 months for 5 years followed by every year for 10 years.
