Impact of Short Term Lenalidomide on Immune Response to Prevnar 13® in Individuals With Chronic Lymphocytic Leukemia (CLL), Small Lymphocytic Leukemia (SLL), and Monoclonal B Cell Lymphocytosis (MBL)

This randomized phase II trial studies how well lenalidomide improves immune response to
pneumococcal 13-valent conjugate vaccine in patients with chronic lymphocytic leukemia, small
lymphocytic lymphoma, or monoclonal B cell lymphocytosis. Biological therapies, such as
lenalidomide, use substances made from living organisms that may stimulate or suppress the
immune system in different ways and stop cancer cells from growing. Lenalidomide may also
improve the effectiveness of pneumococcal 13-valent conjugate vaccine that is used to prevent
infection.

PRIMARY OBJECTIVES:

I. To assess the ability of a 6 week course of low dose lenalidomide to improve the
proportion of patients with monoclonal B cell lymphocytosis (MBL) and chronic lymphocytic
leukemia (CLL) who develop an immune response to pneumococcal vaccination as measured by the
proportion of patients with >= 4-fold rise from pre-vaccine (day 15) for >= 2 of the 3
serotypes measured at 28 days post-vaccination by opsonophagocytic activity (OPA) of
antibodies from sera.

SECONDARY OBJECTIVES:

I. Evaluate disease status by physical exam and complete blood counts in patients
participating in each arm of the study at the time of the 6 week assessment of immune
response.

II. Evaluate time to treatment for progressive CLL for patients on each study arm.

III. Evaluate the adverse events profile in each study arm.

TERTIARY OBJECTIVES:

I. To assess the immune response to pneumococcal vaccination as measured by fold-change from
pre-vaccine (day 15) to 28 days post-vaccination in OPA geometric mean titers (GMT) of
antibodies from sera.

II. To assess the immune response to pneumococcal vaccination as measured by fold-change from
pre-vaccine (day 15) to 28 days post-vaccination in quantitative Streptococcus pneumoniae
immunoglobulin G (IgG) GMT of antibodies from sera.

III. Evaluate the effect of 6 weeks of low dose lenalidomide on global immune function
including T-cell repertoire, T-cell immune synapse, serum immunoglobulin levels, and absolute
numbers of T-cell and natural killer (NK) cells.

OUTLINE: Patients are randomized 1 of 2 treatment arms.

ARM I: Patients receive lenalidomide orally (PO) once daily (QD) on days 1-42 and
pneumococcal 13-valent conjugate vaccine intramuscularly (IM) on day 15.

ARM II: Patients receive pneumococcal 13-valent conjugate vaccine IM on day 15.

After completion of study treatment, patients are followed up at day 28, and then every 6
months for up to 2 years.

Inclusion Criteria:

- Diagnosis of:

1. CLL according to the National Cancer Institute (NCI) criteria

2. Small lymphocytic lymphoma (SLL) according to the World Health Organization (WHO)
criteria

3. MBL according to the consensus criteria

- This includes previous documentation of:

- Biopsy-proven small lymphocytic lymphoma or

- Diagnosis of CLL or MBL as evidenced by all of the following:

- Clonal B-cell population in the peripheral blood with
immunophenotyping consistent with CLL defined as:

- The population of lymphocytes share both B-cell antigens
(cluster of differentiation [CD]19, CD20 [typically dim
expression], or CD23) as well as CD5 in the absence of other
pan-T-cell markers (CD3, CD2, etc)

- Clonality as evidenced by k (kappa) or lambda light chain
expression (typically dim immunoglobulin expression) or other
genetic method (e.g. immunoglobulin heavy chain variable
[IGHV] analysis) NOTE: splenomegaly, hepatomegaly, or
lymphadenopathy are not required for the diagnosis of CLL

- Patients with a peripheral blood B-cell lymphocyte count of < 5 x
10^9/L and no evidence of lymphadenopathy or organomegaly will be
classified as MBL; patients with a peripheral blood B-cell
lymphocyte count of < 5 x 10^9/L who have evidence of
lymphadenopathy will be classified as SLL; patients with a
peripheral blood B-cell lymphocyte count >= 5 x 10^9/L will be
considered to have CLL

- Before diagnosing MBL, CLL or SLL, mantle cell lymphoma must be
excluded by demonstrating a negative fluorescence in situ
hybridization (FISH) analysis for t(11;14)(IgH/cyclin D 1 [CCND1])
on peripheral blood or tissue biopsy or negative
immunohistochemical stains for cyclin D1 on involved tissue biopsy

- CLL or SLL patients only (does not apply to MBL patients): Rai stage 0-1 (both CLL and
SLL patients can be staged using the Rai system)

- Patients must not previously have received the Prevnar 13 pneumococcal vaccination;
NOTE: previous vaccination with Pneumovax (PCV23) is permitted but must have been at
least 365 days prior to registration

- Patients must be previously untreated and must NOT have any of the following
indications for chemotherapy:

- Evidence of progressive marrow failure as manifested by the development of or
worsening anemia (=< 11 g/dL) and/or thrombocytopenia (=< 100 x 10^9/L) not due
to autoimmune disease

- Symptomatic or progressive lymphadenopathy, splenomegaly or hepatomegaly

- One or more of the following disease-related symptoms:

- Weight loss >= 10% within the previous 6 months

- Extreme fatigue attributed to CLL

- Fevers > 100.4 degree Fahrenheit (o^F) for 2 weeks without evidence of
infection

- Drenching night sweats without evidence of infection Note: 1) Prior
chemotherapy or monoclonal antibody based therapy for treatment of CLL or
SLL will be considered prior therapy; nutraceutical treatments with no
established benefit in CLL (such as epigallocatechin gallate or EGCG, found
in green tea or other herbal treatments) will not be considered "prior
treatment" 2) Prior corticosteroid therapy for an indication other than
CLL/SLL will not be considered "prior treatment"; previous use of
corticosteroids for treatment of autoimmune complications of CLL/SLL does
not constitute prior therapy for CLL/SLL

if total bilirubin is > 1.5 x ULN, a direct bilirubin should be performed and must be
