- Patients must have received imatinib therapy for at least 12 months and must not have had changes in their dose of imatinib in the last 6 months. Patients must not have had a continuous interruption of imatinib therapy of greater than 14 days or for a total of 6 weeks in the 6 months prior to enrollment.
- Patients must be in complete cytogenetic remission confirmed by two marrows, the second being at least one month after the first.
- Patients must have detectable BCR-ABL transcript levels that are not more than 0.5-log lower than the lowest value obtained in the last 6 months, with at least two values obtained during this period.
- Karnofsky performance status should be \> 70.
- Adequate organ function defined as: bilirubin \<2x upper limit of normal (ULN), creatinine \<1.5x ULN, and ALT and AST \<2.5x ULN.

Accelerated phase is defined as 15 to 30% blasts or \>30% blasts plus promyelocytes in the peripheral blood or marrow, \>20% basophils, or platelets \<100 x 10\^9/L, unrelated to therapy. Cytogenetic abnormalities in addition to the Ph chromosome are not considered a defining feature of accelerated phase.
- Patients with autoimmune disorders or known immune deficiency.
- Patients receiving immunosuppressive therapy, corticosteroids, chemotherapy, or therapy for CML other than imatinib.
- Patients receiving any other investigational agents.
- Patients who are pregnant or breast-feeding.
- Patients with clinically significant heart disease (New York Heart Association Class III or IV) or other serious intercurrent illnesses, active uncontrolled infections requiring antibiotics or active bleeding.
