• All prospective participants must have an Ommaya reservoir (or equivalent ventricular access device) inserted as part of their standard clinical care prior to initiation of study treatment.

• No concurrent methotrexate, thiotepa, cytarabine, or investigational agents

• Absolute neutrophil count (ANC) > 1,500 (growth factors permitted)

FCBPs must also agree to ongoing pregnancy testing and for 28 days after receiving their last dose of lenalidomide.

• Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy.

• Able to take aspirin (81 or 325 mg) daily as prophylactic anticoagulation (patients intolerant to aspirin may use warfarin or low molecular weight heparin).

• All study participants must be registered into the mandatory RevAssist® program, and be willing and able to comply with the requirements of RevAssist®.

Exclusion Criteria:

• Intraventricular chemotherapy or radiation therapy within 4 days of starting treatment

• Intravenous rituximab within 30 days of starting treatment

• Persistent neurotoxicity from intraventricular methotrexate, cytarabine, thiotepa

• Anticipated survival of less than 1 month

• Pregnant women and women of child-bearing potential who are not using an effective method of birth control.

• Known hypersensitivity to thalidomide or lenalidomide

• The development of erythema nodosum if characterized by a desquamating rash while taking thalidomide or similar drugs.

• Known seropositive for or active viral infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV). Patients who are seropositive because of hepatitis B virus vaccine are eligible.

• Contraindication to aspirin. If unable to take aspirin, contraindication to warfarin or low molecular weight heparin.
