Brief Summary:
This is a phase I/II study of DT2219 for the treatment of relapsed or refractory CD19 (+) and/or CD 22 (+) B-lineage leukemia and lymphoma. The study consists of two phases - a phase I dose/schedule finding component using the maximum tolerated dose identified during the previous phase I study, but with a higher number of doses and a two-stage phase II extension component to confirm safety and make a preliminary determination of the activity level by disease using the dose identified in phase I.

Arm Intervention/treatment
Experimental: DT2219ARL
A recombinant bispecific antibody-targeted toxin.
Biological: DT2219ARL
DT2219ARL at assigned dose IV on day 1, 3, 5, 8 and day 15, 17, 19, and 22. Up to 2 additional courses of DT2219ARL may be given until disease progression and/or unacceptable toxicity.




Primary Outcome Measures :
  1. Phase I: Incidence of Any DLT Attributed to DT2219 in the First Cycle [ Time Frame: Day 1 - Day 29 ]

    Dose limiting toxicity (DLT) is defined as any of the following adverse events occurring from study day 1 through 7 days after the last dose of DT2219 of the 1st treatment cycle, and not clearly attributed to the primary malignancy or intercurrent illness:

    • any Grade 5 adverse event
    • any Grade 4 neutropenia or thrombocytopenia lasting more for than 7 days
    • any Grade 3 thrombocytopenia with bleeding
    • any Grade 4 non-hematologic adverse event during DT2219 infusion
    • any Grade 3 non-hematologic adverse event occurring after completion of DT2219 infusion

  2. Phase ll: Overall Disease Response [ Time Frame: Day 29 ]

    Response is defined as complete response, partial response and stable disease. Complete response is defined as the disappearance of all signs of cancer in response to treatment. This does not always mean the cancer has been cured.

    Partial response is defined as a decrease in the size of a tumor, or in the extent of cancer in the body, in response to treatment.

    Stable disease is defined as cancer that is neither decreasing nor increasing in extent or severity.



Secondary Outcome Measures :
  1. Incidence of Serious Adverse Events [ Time Frame: Day 29 ]

    A Serious Adverse Event is defined as an adverse event that results in any of the following outcomes:

    • Death
    • A life-threatening adverse event
    • Inpatient hospitalization or prolongation of existing hospitalization
    • A persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions
    • A congenital anomaly/birth defect.
    • Important medical event

  2. Phase II : Duration of Response [ Time Frame: 1 year ]
    Duration of response was calculated as duration between on-study date and best response date for those patients who achieved complete remission (CR) or partial response (PR)

  3. Disease-free Survival [ Time Frame: 1 year ]
  4. Overall Survival [ Time Frame: 1 year ]
  5. Time to Relapse/Progression [ Time Frame: 1 year ]
