Adequate hematologic function as indicated by a platelet count ≥ 25 x 109/L, a neutrophil count ≥ 1,0 x 109/L and a hemoglobin value ≥ 8.0 g/dL, unless directly attributable to the patient´s CLL (e.g. bone marrow infiltration)~3. Adequate renal function as indicated by a creatinine clearance ≥ 30ml/min calculated according to the modified formula of Cockcroft and Gault or directly measured with 24 hrs urine collection~4. Adequate liver function as indicated by a total bilirubin ≤ 2x, 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~5. Negative serological testing for hepatitis B, negative testing for hepatitis-C RNA and negative HIV antibody test within 6 weeks prior to registration~6. Age ≥ 18 years~7. Eastern Cooperative Oncology Group (ECOG) Performance Status 0 to 2, ECOG 3 is only permitted if related to CLL (e.g. due to anemia or severe constitutional symptoms)~8. Life expectancy ≥ 6 months~9. Ability and willingness to provide written informed consent and to adhere to the study visit schedule and other protocol requirements~Exclusion Criteria:~1. Transformation of CLL (i.e. Richter's transformation, pro-lymphocytic leukemia)~2. Known central nervous system (CNS) involvement~3. Patients with confirmed progressive multifocal leukoencephalopathy (PML)~4. Malignancies other than CLL currently requiring systemic therapy~5. Uncontrolled infection requiring systemic treatment~6. 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)~7. Use of investigational agents which might interfere with the study drug within 3 days prior to Registration~8. Known hypersensitivity to ofatumumab, ibrutinib or any of the excipients Please note: Patients with a known hypersensitivity to bendamustine are allowed to participate but will not receive a debulking with bendamustine~9. Requirement of treatment with strong CYP3A4-inhibitors/-inducers or anticoagulant with phenprocoumon (marcumar), warfarin, or other vitamin k antagonists~10. History of stroke or intracranial hemorrhage within 6 months prior to registration~11. Pregnant women and nursing mothers (a negative pregnancy test is required for all women of childbearing potential within 7 days before start of treatment and monthly during debulking, induction and maintenance therapy)~12. 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 12 months after end of study treatment.~13.
