Eligibility criteria
Inclusion Criteria:
* documented chronic lymphocytic leukemia (CLL) requiring treatment according to International Working Group on CLL (iwCLL) criteria
* adequate hematologic function: platelets ≥ 25.000/µl, neutrophils ≥ 1.000/µl and hemoglobin ≥8.0 g/dL, unless directly attributable to the patient´s CLL (e.g. bone marrow infiltration)
* adequate renal function: a creatinine clearance ≥30ml/min calculated according to the modified formula of Cockcroft and Gault or directly measured with 24 hr. urine collection
* adequate liver function: total bilirubin ≤1,5x, aspartate aminotransferase (AST) / alanin aminotransferase (ALT) ≤2.5x the institutional upper limit of normal (ULN) value, unless directly attributable to the patient's CLL or to Gilbert's Syndrome
* negative serological testing for hepatitis B, negative testing for hepatitis-C RNA and negative HIV test within 6 weeks prior to registration
* age ≥ 18 years
* Eastern Cooperative Oncology Group (ECOG) Performance Status 0 to 2, ECOG 3 is only permitted if related to CLL
* life expectancy ≥ 6 months
* ability and willingness to provide written informed consent and to adhere to the study visit schedule and other protocol requirements
Exclusion Criteria:
* transformation of CLL (i.e. Richter's transformation, prolymphocytic leukemia)
* known central nervous system (CNS) involvement
* confirmed progressive multifocal leukoencephalopathy (PML)
* malignancies other than CLL currently requiring systemic therapies
* uncontrolled infection requiring systemic treatment
* any comorbidity or organ system impairment rated with a cumulative illness rating scale (CIRS) score of 4, excluding the eyes/ears/nose/throat/larynx organ system or any other life-threatening illness, medical condition or organ system dysfunction that - in the investigator´s opinion - could compromise the patients safety or interfere with the absorption or metabolism of the study drugs (e.g, inability to swallow tablets or impaired resorption in the gastrointestinal tract)
* ongoing inflammatory bowel disease
* ongoing drug induced pneumonitis
* use of investigational agents which would interfere with the study drug ≤28 days prior to registration
* known hypersensitivity to GA101 (obinutuzumab), CAL-101 (idelalisib) or any of the excipients
* pregnant women and nursing mothers
* fertile men or women of childbearing potential unless surgically sterile or ≥ 2 years after the onset of menopause, or willing to use two methods of reliable contraception including one highly effective (Pearl Index \<1) and one additional effective (barrier) method during study treatment and for 18 months after end of study treatment
* vaccination with a live vaccine ≤28 days prior to registration
* legal incapacity
* prisoners or subjects who are institutionalized by regulatory or court order
* persons who are in dependence to the sponsor or an investigator
