Application Title:

Bone Marrow Targeting of Hematopoietic Stem Cells Engineered to Overexpress 25-OH-VD3 1-α-hydroxylase for Acute Myeloid Leukemia Therapy

Public Abstract:
Research Objective

We propose a new approach to differentiation therapy for acute myeloid leukemia by producing local level of high-dose vitamin D in bone marrow via cell therapy with engineered hematopoietic stem cells

Impact

If proven successful, the proposed research can serve as a major breakthrough in the treatment of multiple subtypes of AML and particularly important for improving survival in older patients.

Major Proposed Activities

  • Evaluate homing and expansion of engineered hematopoietic stem cells in bone marrow of human leukemic xenograft (HLX) mice after precondition with 5-Azacytidine
  • Optimize the number of injected hematopoietic stem cells without causing hypercalcemia
  • Determine if the local concentration of vitamin D3 is sufficient to differentiate leukemic blasts in bone marrow
  • Determine the efficacy of combination therapy of 5-Azacytidine and cell therapy by measuring overall survival
  • Determine the efficacy of combination therapy of 5-Azacytidine and cell therapy by measuring leukemia burden
  • Monitor serum calcium level from peripheral blood during treatment period
Statement of Benefit to California:
Acute myeloid leukemia (AML) has poor outcome, especially in older, ailing patients who can't tolerate aggressive conventional chemotherapy. If proven successful, our work can serve as a major breakthrough in the treatment of multiple subtypes of AML and particularly important for improving survival in older patients. The State of California will be a leading authority in this field. Further, this work will benefit patients around the world, not limited citizens of California
