Exclusion Criteria:

Recipient Exclusion Criteria
Diagnosis of acute promyelocytic leukemia
Active refractory or relapsed acute leukemia
Prior use of fludarabine, as this agent has been associated with higher subsequent rates of graft versus host disease
Individuals with a history of a different malignancy are ineligible except for the following circumstances. Individuals with a history of other malignancies are eligible if they have been disease-free for at least 3 years and are deemed by the investigator to be at low risk for recurrence of that malignancy. Individuals with the following cancers are eligible if diagnosed and treated within the past 3 years: cervical cancer in situ, and basal cell or squamous cell carcinoma of the skin.
Uncontrolled intercurrent illness that would limit compliance with study requirements.
HIV-positive individuals on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with study drug. In addition, these individuals are at increased risk of lethal infections when treated with marrow-suppressive therapy.
A diagnosis of active hepatitis B or C as defined by detectable viral load assays in the blood
Known hypersensitivity to thalidomide or lenalidomide.
The development of erythema nodosum if characterized by a desquamating rash while taking lenalidomide.

Significant cardiac disease as determined by the investigator including:

Known or suspected cardiac amyloidosis
Congestive heart failure of Class III or IV of the NYHA classification
Uncontrolled angina, hypertension or arrhythmia
Myocardial infarction in past 6 months
Any uncontrolled or severe cardiovascular disease
Prior cerebrovascular event with persistent neurologic deficit
Medical conditions that, in the investigator's opinion, would impose excessive risk to the subject.
Equal to or greater than grade 2 ataxia, cranial or peripheral neuropathy.
Systemic infection requiring IV antibiotic therapy within 7 days preceding the first dose of study drug, or other severe infection.
Pregnant women are excluded from this study.
