-
Cardiac Function: Patient must have normal cardiac function documented within two weeks before starting of a treatment cycle 1 by:
- Ejection fraction (> 55%) documented by echocardiogram or fractional shortening (≥ 28%) documented by echocardiogram.
- Liver Function: Total bilirubin ≤ 1.5 x normal for age, and ALT (SGPT) and AST (SGOT) ≤ 3 x normal for age.
- Room air pulse oximetry > 94%.
- Female patients of childbearing potential must have a negative serum pregnancy test within 7 days of enrollment.
- Male and female patients must agree to use a medically acceptable barrier and/or chemical contraceptive method during the study and for a minimum of 3 months after the last dose of chemotherapy on this study.
- Subjects must be > 3 months and < 12 months post-SCT at the time of the first vaccination.
- Donor chimerism must be > 90%, assist at least two weeks prior to beginning treatment
- Subjects must be at least 30 days post-transplant to enroll on the study and to undergo apheresis, and must be at least three months post-transplant to begin therapy with DAC/vaccine.
- Stem cell donor source may be related or unrelated donor cord blood, related or unrelated donor bone marrow, and related or unrelated donor peripheral blood stem cell product. Donors may be no more than two HLA (A, B, C, DR, DQ) antigen mismatched with the recipient.
Exclusion Criteria:

- Pregnant or lactating females are excluded.
- Other active systemic malignancy other than leukemia expected to require therapy within 4 months.
- Patients with a systemic fungal, bacterial, viral, or other infection not controlled (defined as exhibiting ongoing signs/symptoms related to the infection and without improvement, despite appropriate antibiotics or other treatment).
- Any condition which, in the opinion of the investigator, would compromise patient safety or compliance, interfere with consent, study participation, follow up, or interpretation of study results.
