Exclusion Criteria: * Patients with IGHV mutated (except VH3-21/subset #2) with normal karyotype and/or del 13q without TP53 mutation ie low risk patients. * Patients del 17p and or TP53 mutation ie high risk patients. * CLL without active disease according to IWCLL 2008 criteria. * Known HIV seropositivity. * Evidence of other clinically significant uncontrolled condition(s) including, but not limited to: * Uncontrolled and/or active systemic infection (viral, bacterial or fungal) * Chronic hepatitis B virus (HBV) or hepatitis C (HCV) requiring treatment.
