Brief Summary

The standard approach to managing chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL) is to wait until you have symptoms before treatment is given. The goal of this clinical research study is to learn if providing earlier treatment for CLL or SLL with ibrutinib in patients who do not have symptoms will be more effective than waiting until symptoms develop. This is an investigational study. Ibrutinib is FDA approved and commercially available for the treatment of patients with CLL or SLL. It is considered investigational to give ibrutinib to CLL and SLL patients before symptoms develop. The study doctor can describe how the study drug is designed to work. Up to 50 participants will be enrolled in this study. All will take part at MD Anderson.

Outcome Measures

Primary Outcomes (2)

• Participants With Complete Remission (CR) at 24 Months

  Complete Remission (CR): Peripheral blood lymphocytes below 4 x 10\^9/L (4000/ƒÝL), Absence of significant lymphadenopathy (lymph nodes \>1.5 cm in diameter) by CT(or PET) examination of neck, thorax, abdomen and pelvis, No hepatomegaly or splenomegaly by physical examination (and CT/PET if assessment was abnormal before therapy or if physical exam is inconclusive), Absence of constitutional symptoms, Neutrophils more than 1.5 x 10\^9/L (1500/ƒÝL) without need for exogenous growth factors, Platelets more than 100 x 10\^9/L (100 000/ƒÝL) without need for exogenous growth factors, Hemoglobin more than 110 g/L (11.0 g/dL) without red blood cell transfusion or need for exogenous erythropoietin, Bone Marrow aspirate and biopsy, demonstrating at least normocellular for age, with less than 30% of nucleated cells being lymphocytes. Lymphoid nodules should be absent. If the bone marrow is hypocellular, a repeat determination should be made in 4 weeks or when peripheral blood counts have recovered.

  Up to 24 months

• Participants With Partial Remission (PR) at 24 Months

  Partial Remission (PR) at least one of criteria 1-3, and one or more of the features listed in number 4. 1. A decrease lymphocytes by 50% or more from the value before therapy. 2. Reduction in lymphadenopathy, defined by the following: - A decrease in lymph node size by 50% or more either in the sum products of up to 6 lymph nodes, or in the largest diameter of the enlarged lymph node(s) detected prior to therapy. - No increase in lymph node, and no new enlarged lymph node. In small lymph nodes (\</=2 cm), an increase of less than 25% is not considered to be significant. 3. A reduction in enlargement of the spleen or liver by 50% or more. 4. The blood count should show one or more of the following results: - Neutrophils more than 1, without need for exogenous growth factors. - Platelet counts greater than 100 x10\^9/L (100 000/ƒÝL) or 50% improvement over baseline without need for exogenous growth factors. - Hemoglobin greater than 11

  Up to 24 months

• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients must be age \>/=18 years at the time of informed consent, understand and voluntarily sign an informed consent, and be able to comply with study procedures and follow-up examinations.
• No treatment indication according to IWCLL/NCI-WG (International Working Group in Chronic Lymphocytic Leukemia/National Cancer Institute-Working Group) 2008 criteria
• Estimated time to first treatment of 3 years or less according to MDACC nomogram
• ECOG performance status of 0-2
• Male and female subjects who agree to use both a highly effective method of birth control (eg, implants, injectables, combined oral contraceptives, some intrauterine devices \[IUDs\], complete abstinence , or sterilized partner) and a barrier method (eg., condoms, vaginal ring, sponge, etc) during the period of therapy and for 30 days after the last dose of study drug for females and 90 days for males. OR Female subjects who are of non-reproductive potential (ie, post-menopausal by history - no menses for \>/=1 year; OR history of hysterectomy; OR history of bilateral tubal ligation; OR history of bilateral oophorectomy)
• Adequate hepatic and renal function as indicated by all of the following: Total bilirubin \</=1.5 x institutional Upper Limit of Normal (ULN) except for patients with bilirubin elevation due to Gilbert's disease or of non-hepatic origin who will be allowed to participate, provided bilirubin is \</=3 x institutional ULN; an ALT \</=2.5 x ULN; and estimated creatinine clearance (CrCl) of \> 30 mL/min, as calculated by the Cockcroft- Gault equation.
• PT/INR \<1.5 x ULN and PTT (aPTT) \<1.5 x ULN (unless abnormalities are unrelated to coagulopathy or bleeding disorder).
• Free of prior malignancies for 3 years with exception of patients diagnosed with basal cell or non-metastatic squamous cell carcinoma of the skin, or carcinoma in situ of the cervix or breast, who are eligible even if they are currently treated or were treated and/or diagnosed in the past 3 years prior to study enrolment
• Diagnosis of CLL/SLL that meets IWCLL diagnostic criteria

You may not qualify if:

• Receipt of any prior therapy for CLL. Patients who have received "early intervention" with INVAC-1 vaccine against hTERT will be eligible provided all of the following exist: i) They had no response to the vaccine treatment (persistent CLL \>1% in bone marrow). ii) ≥3 months have elapsed since the last dose of vaccine. iii) No residual toxicities attributable to the vaccine exist at the time of study enrollment. iv) The patient does not meet IWCLL criteria for requiring treatment.
• Richter Transformation
• Active malignancy requiring systemic therapy, other than CLL, with the exception of: adequately treated in situ carcinoma of the cervix uteri; adequately treated basal cell carcinoma or localized squamous cell carcinoma of the skin; previous malignancy confined and surgically resected (or treated with other modalities) with curative intent.
• Systemic anticoagulation with warfarin or other Vitamin K antagonists
• Active and uncontrolled autoimmune hemolytic anemia (AIHA) or autoimmune thrombocytopenia (ITP) requiring daily prednisone dose of \>/=20 mg
• Current and concurrent use of strong CYP3A4 inhibitors or inducers
• Pregnant or breast-feeding females
• Uncontrolled and active systemic fungal, bacterial, viral, or other infection (defined as exhibiting ongoing signs/symptoms related to the infection and without improvement, despite appropriate antibiotics or other treatment)
• Any other severe concurrent disease, or history of serious organ dysfunction or disease involving the heart, kidney, liver or other organ system that, in the investigator's opinion, may place the patient at undue risk to undergo therapy with ibrutinib
• Currently active, clinically significant cardiovascular disease, such as uncontrolled arrhythmia or Class 3 or 4 congestive heart failure as defined by the New York Heart Association Functional Classification; or a history of myocardial infarction, unstable angina, or acute coronary syndrome within 6 months prior to randomization
• History of ischemic stroke within 6 months prior to enrollment
• Evidence of bleeding diathesis or coagulopathy within 3 months (eg, von Willebrand's disease or hemophilia
• Any history of symptomatic intracranial hemorrhage
• Major surgical procedure with 4 weeks of first dose of study drug; open biopsy, or significant traumatic injury within 7 days prior to enrollment date; anticipation of need for major surgical procedure during the course of the study
