  • Total bilirubin =< 1.5 x upper limit of normal (ULN) unless due to Gilbert's disease. For those with a total bilirubin > 1.5 x ULN, a direct bilirubin should be performed and must be < 1.5 mg/dL for Gilbert's to be diagnosed (obtained =< 14 days prior to registration)
  • Serum glutamic-oxaloacetic transaminase (SGOT) (aspartate aminotransferase [AST])/serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) =< 3.0 x the institutional ULN (obtained =< 14 days prior to registration)
  • Prothrombin time (PT)/international normalized ratio (INR) < 1.5 ULN and partial thromboplastin time (PTT) (activated partial thromboplastin time [aPTT]) < 1.5 x ULN (obtained =< 14 days prior to registration)
  • NOTE: If value is higher due to hepatic involvement by CLL, patient is eligible
  • No active hemolytic anemia requiring immunosuppressive therapy or other pharmacologic treatment. Patients who have a positive Coombs test but no evidence of hemolysis are NOT excluded from participation
  • No current use of corticosteroids. EXCEPTION: Low doses of steroids (< 10 mg of prednisone or equivalent dose of other steroid) used for treatment of non-hematologic medical condition (e.g. chronic adrenal insufficiency) is permitted
  • No previous autoimmune complications (e.g. autoimmune hemolytic anemia or immune thrombocytopenia) that have developed since the initial diagnosis of CLL and have required treatment with high dose corticosteroids (e.g. equivalent of > 20 mg/day of prednisone), monoclonal antibody based therapy, or chemotherapy. Prior use of corticosteroids for reasons other than treatment of autoimmune complications is allowed
  • No other active primary malignancy (other than non-melanomatous skin cancer or carcinoma in situ of the cervix) requiring treatment or limiting expected survival to =< 2 years
  • NOTE: If there is a history of prior malignancy, the patient must not currently be receiving other specific treatment (other than hormonal therapy for their cancer)
  • Able to adhere to the study visit schedule and other protocol requirements
  • No major surgery within 4 weeks (28 days) of first dose of study drug or minor surgery within 3 days of first dose of study drug
  • No radiation therapy =< 4 weeks prior to registration
  • Patients who are human immunodeficiency virus positive (HIV+) with undetectable HIV viral load are eligible provided they meet all other protocol criteria for participation and are not being treated with protease inhibitors or any non-nucleoside reverse transcriptase inhibitors (NNRTI) that are CYP3A4 inducers; if being treated for HIV, patients should be receiving an alternative antiretroviral therapy (ART) that is not a CYP3A inhibitor
  • Patients must not have any of the following conditions:
  • Congestive heart failure or New York Heart Association Functional Classification III or IV congestive heart failure

  • Patients are not eligible if they require treatment with a strong cytochrome P450 (CYP) 3A inhibitor

  • Strong and Moderate CYP3A inhibitors
  • Strong and Moderate CYP3A inducers
  • Patients may not be on any other investigational agents
  • Patients may not have received warfarin or another vitamin K antagonist in the preceding 30 days
  • Women must not be pregnant or breast-feeding since this study involves investigational agents whose genotoxic, mutagenic, and teratogenic effects on the developing fetus and newborn are unknown. All females of childbearing potential must have a blood test within 2 weeks prior to registration to rule out pregnancy. A female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: 1) ) has achieved menarche at some point , 2) has not undergone a hysterectomy or bilateral oophorectomy; or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
  • Women of childbearing potential and sexually active males must be strongly advised to use accepted and highly effective method(s) of contraception or to abstain from sexual intercourse for the duration of their participation in the study and for:
  • 18 months after the last dose of obinutuzumab
  • 90 days after the last dose of ibrutinib, and
