Diagnosis of CLL/SLL that meets published diagnostic criteria (Hallek 2008): a) Monoclonal B-cells (either kappa or lambda light chain restricted) that are clonally co expressing at least one B-cell marker (CD19, CD20, or CD23) and CD5, b) The diagnosis of CLL requires a history of lymphocytosis with a B-lymphocyte count ?5,000/µl while SLL patients are characterized by the same criteria with a circulating B lymphocyte count <5,000/µl. Prolymphocytes may comprise no more than 55% of blood lymphocytes5. Active disease meeting at least 1 of the following IWCLL 2008 criteria for requiring treatment: a) Evidence of progressive marrow failure as manifested by the development of, or worsening of, anemia (Hgb < 11 g/dL) and/or thrombocytopenia (platelets < 100,000/L), b) Massive, progressive, or symptomatic splenomegaly, c) Massive nodes, progressive, or symptomatic lymphadenopathy, d) Progressive lymphocytosis with an increase of > 50% over a 2-month period or a lymphocyte doubling time (LDT) of < 6 months. LDT may be obtained by linear regression extrapolation of absolute lymphocyte counts (ALC) obtained at intervals of 2 weeks over an observation period of 2 to 3 months. In patients with initial blood lymphocyte counts of < 30 X 109/L (30,000/?L), LDT should not be used as a single parameter to define indication for treatment. In addition, factors contributing to lymphocytosis or lymphadenopathy other than CLL should be excluded, e) Autoimmune anemia and/or thrombocytopenia that is poorly responsive to corticosteroids or other standard therapy, f) Constitutional symptoms, defined as one or more of the following disease-related symptoms or signs, i) Unintentional weight loss > 10% within the previous 6 months prior to Screeningii) Significant fatigue; iii) Fevers higher than 100.5° F or 38 .0° C for 2 or more weeks prior to Screening without evidence of infection or iv) Night sweats for more than 1 month prior to Screening without evidence of infection6.

CIRS score can be determined utilizing a web-based tool.c) History of purine analog-associated autoimmune anemia or autoimmune thrombocytopenia, d) FISH showing 17p del in ? 20% of cells (either at diagnosis or any time before study entry) either alone or in combination with other cytogenetic abnormalities, provided they have received at least one prior therapy 7.
