A Phase 2 Clinical Trial To Evaluate The Immune Restoration Potential Of Lenalidomide For Patients With CLL-Associated Immunodeficiency

This is phase 2 study of the immunomodulatory drug, lenalidomide, to evaluate potential
beneficial effects on the immune system of patients with chronic lymphocytic leukemia (CLL)
and CLL-associated immunodeficiency. 17 patients will be enrolled with CLL, small
lymphocytic lymphoma (SLL), or monoclonal B-cell lymphocytosis (MBL), and measurable immune
compromise, but not an iwCLL indication for CLL therapy (ie non-progressive disease).

This is phase 2 study of the immunomodulatory drug, lenalidomide, to evaluate potential
beneficial effects on the immune system of patients with chronic lymphocytic leukemia (CLL)
and CLL-associated immunodeficiency. 17 patients will be enrolled with CLL, small
lymphocytic lymphoma (SLL), or monoclonal B-cell lymphocytosis (MBL), and measurable immune
compromise, but not an iwCLL indication for CLL therapy (ie non-progressive disease).
Lenalidomide will be administered orally for 21 days of each 28 day cycle, starting at a
2.5mg dose, with dose escalation each cycle to a maximum of 25mg in the absence of any grade
2 or higher hematologic or non-hematologic adverse events. Treatment duration to primary
endpoint assessment is 6 cycles, though patients will not be restricted from continuing
lenalidomide off-study, if clinically indicated

Main Inclusion Criteria:

1. Clinical and phenotypic verification of B cell CLL/ SLL/ or MBL and measurable
disease.

2. Subjects must have total serum IgG < 500 mg/dL

3. Disease Status/ Prior Therapy: There is not any requirement nor restriction for prior
therapy.

4. Recovered from the toxic effects of prior therapy to their clinical baseline.

5. Both men and women of all races and ethnic groups are eligible for this trial.

6. Women of childbearing potential (not postmenopausal for at least one year or not
surgically incapable of bearing children) must agree not to become pregnant for the
duration of the study. Both men and women must agree to use a barrier method of
contraception for the duration of the study and until 8 weeks after the final dose of
lenalidomide.

7. ECOG performance status of 0-2.

8. Adequate hematologic function:

8.1. Platelet count ≥ 50,000/µL; AND 8.2. Hemoglobin ≥ 8.0 g/dL 8.3. Absolute
neutrophil count > 1000 /uL

9. Adequate renal function:

9.1. Serum creatinine <1.5 times upper limit of normal; OR 9.2. Calculated Creatinine
clearance (CrCl) ≥ 50 mL/min

10. Adequate hepatic function:

12.1. Total bilirubin ≤ 2.5 times upper limit of normal; AND 12.2. ALT ≤ 2.5 times
upper limit of normal.

11. Able to take aspirin (81mg or 325mg) daily, warfarin, low molecular weight heparin,
or equivalent anticoagulation as prophylactic medication.

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

13. Females of childbearing potential must have a negative serum or urine pregnancy test
with a sensitivity of at least 50 mIU/mL within 10 - 14 days prior to and again
within 24 hours prior to starting Revlimid® and must either commit to continued
abstinence from heterosexual intercourse or begin TWO acceptable methods of birth
control, one highly effective method and one additional effective method AT THE SAME
TIME, at least 28 days before she starts taking Revlimid®. Men must agree to use a
latex condom during sexual contact with a FCBP even if they have had a successful
vasectomy.

14. Females of reproductive potential must adhere to the scheduled pregnancy testing as
required in the Revlimid REMS® program.

Exclusion Criteria:

1. Progressive CLL requiring therapy based on 2008 international working group
guidelines (iwCLL 2008, Hallek et al, Blood 2008).

2. Pregnant or breast-feeding women will not be entered on this study due to risks of
fetal and teratogenic adverse events as seen in animal/human studies.

3. Known hypersensitivity to thalidomide or lenalidomide.

4. Prior lenalidomide-associated deep vein thrombosis

5. Deep vein thrombosis or superficial thrombophlebitis of any cause on current
anticoagulation therapy at the time of screening.

6. Patients who are currently receiving another investigational agent are excluded.

7. Patients who have had chemotherapy (e.g., purine analogues, alkylating agents),
radiation therapy, tyrosine kinase inhibitor therapy, or participation in any
investigational drug treatment within 4 weeks of initiation of lenalidomide or at any
time during the study.

8. Patients who have had prior (within 8 weeks of initiation of lenalidomide) or
concurrent antibody therapy directed against CLL.

9. Current infection requiring parenteral antibiotics.

10. Known seropositive for or active viral infection with human immunodeficiency virus
(HIV); or known active infection with hepatitis B virus (HBV) or hepatitis C virus
(HCV) based on detectable viral load. Patients who are seropositive because of
hepatitis B virus vaccine are eligible.

11. Active malignancy within the previous 2 years (other than completely resected
non-melanoma skin cancer or carcinoma in situ).

12. Known history of IgA or IgG monoclonal gammopathy of undetermined significance (MGUS)

13. Known central nervous system (CNS) involvement by malignancy.

14. Untreated autoimmunity such as autoimmune hemolytic anemia, or immune
thrombocytopenia.
