Inclusion criteria

Age > or = 18.
Has relapsed or refractory disease as defined by the following:
- CLL - refractory to or relapsed after at least 2 prior therapies, including fludarabine, alone or in combination. Patients should not be eligible for transplantation (patients who are candidates for transplantation and have declined transplantation are eligible for this study).
- B-cell NHL - refractory to or relapsed after at least 1 prior chemotherapy regimen and having received rituximab as a single agent or in combination with other therapies.
- AML - refractory to or relapsed after at least 1 cycle of induction chemotherapy. Patients over the age of 70 who are not appropriate candidates for chemotherapy are eligible for this study.
- MM - refractory to or relapsed after at least 2 prior chemotherapy regimens, including bortezomib and thalidomide or lenalidomide (except if the drug is contraindicated in a patient then this requirement is waived).
Disease status requirement:
- For CLL patients, symptomatic disease that mandate treatment.
- For B-cell NHL patients, has measurable disease by CT scan.
- For AML patients, has > 10% blasts in the bone marrow for refractory or relapsed disease and > 20% blasts in the bone marrow if no prior chemotherapy.
- For MM patients, has measurable disease defined by at least 1 of the following 3 measurements: serum M-protein > or = to 1 g/dL, urine M-protein > or = to 200 mg/24 h, or serum free light chain (FLC) assay with involved FLC level > or = to 10 mg/dL provided serum FLC ratio is abnormal.
WHO performance status of ≤ 2.
For men and women of child-bearing potential, willing to use adequate contraception (i.e., latex condom, cervical cap, diaphragm, abstinence, etc.) for the entire duration of the study.

Has active hepatitis B or C. Patients with serologic evidence of prior exposure are eligible.
