I. Estimate therapeutic activity (best response [complete response (CR)/complete response with incomplete recovery (CRi)]) of combined ibrutinib and venetoclax in patients with chronic lymphocytic leukemia (CLL)/small lymphocytic leukemia (SLL).
I. To determine the safety of this combination strategy. II. To estimate the time to best response with this combination. III. To determine the progression-free survival (PFS) and overall survival (OS).
IV. To test pharmacodynamic endpoints and molecular interactions between these two drugs.
V. To assess the therapeutic activity (best response [CR/CRi]) in subgroups of patients defined by immunoglobulin heavy chain variable (IGHV) mutation or fluorescence in situ hybridization (FISH) subtype.
I. To study immunological and molecular changes in the peripheral blood and the bone marrow in response to ibrutinib and venetoclax.
Patients receive ibrutinib orally (PO) once daily (QD) on days 1-28. Beginning on day 1 of cycle 4, patients also receive venetoclax PO QD on days 1-28. Treatment repeats every 28 days for up to 27 cycles in the absence of disease progression or unacceptable toxicity. Patients with residual disease or who are positive for minimal residual disease (MRD) after cycle 27 may continue treatment with ibrutinib.
After completion of study treatment, patients are followed up every 3-6 months.

Experimental: Treatment (ibrutinib, venetoclax)
Patients receive ibrutinib PO QD on days 1-28. Beginning on day 1 of cycle 4, patients also receive venetoclax PO QD on days 1-28. Treatment repeats every 28 days for up to 27 cycles in the absence of disease progression or unacceptable toxicity. Patients with residual disease or who are positive for MRD after cycle 27 may continue treatment with ibrutinib.
Other: Laboratory Biomarker Analysis
- Best response (complete response /complete response with incomplete recovery) of combined ibrutinib and venetoclax [ Time Frame: Up to 2 months after treatment ]For each cohort, the best response (complete response /complete response with incomplete recovery) rate will be estimated along with the exact 95% confidence interval.
- Incidence of toxicities [ Time Frame: Up to 6 weeks of treatment ]Will be defined as prolonged neutropenia or thrombocytopenia lasting > 42 days; febrile neutropenia; hospitalization due to infection; early death; major bleeding due to thrombocytopenia. Will be monitored in each disease cohort separately using the Bayesian method of Thall, Simon and Estey. Safety data will be summarized using descriptive statistics.
- Time to response with combination of ibrutinib and venetoclax [ Time Frame: Up to 8 years ]Estimated using the Kaplan-Meier method in each cohort.
- Overall survival [ Time Frame: Up to 8 years ]Estimated using the Kaplan-Meier method in each cohort.
- Progression-free survival [ Time Frame: Up to 8 years ]Estimated using the Kaplan-Meier method in each cohort.
- Complete response/complete response with incomplete recovery rate in each subgroups of patients [ Time Frame: Up to 8 years ]Will be defined by IGHV mutation or fluorescence in situ hybridization (FISH) subtype. Will be estimated along with the exact 95% confidence interval.
- Changes in immunological biomarkers [ Time Frame: Up to 8 years ]Will be summarized over time and will be assessed using linear or non-linear mixed effect models as appropriate.
- Changes in molecular biomarkers [ Time Frame: Up to 8 years ]Will be summarized over time and will be assessed using linear or non-linear mixed effect models as appropriate.

|Ages Eligible for Study:||18 Years and older (Adult, Older Adult)|
|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||No|
Patients with a diagnosis of CLL/SLL:
- Cohort 1: Refractory to and/or relapsed after at least one prior therapy will be eligible
- Cohort 2: Untreated patients with high-risk features (del(17p), or mutated TP53, or del(11q), or unmutated IGHV, or >= 65 years of age) are eligible (cohort 2) provided they have active disease requiring treatment as defined by the International Working Group for CLL (IWCLL)
- Eastern Cooperative Oncology Group (ECOG) performance status =< 2
- Total bilirubin =< 1.5 x upper limit of normal (ULN) or =< 3 x ULN for patients with Gilbert's disease (in patients [pts] with elevated total bilirubin due to increased indirect bilirubin, pts with direct bilirubin =< 1.5 x ULN are eligible)
- Creatinine clearance > 50 mL/min (calculated according to institutional standards or using Cockcroft-Gault, Modification of Diet in Renal Disease [MDRD], or Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI] formula)
- Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 3.0 x ULN, unless clearly due to disease involvement
- Platelet count of greater than 20,000/mul, with no platelet transfusion in 2 weeks prior to registration; this criteria is waived if the thrombocytopenia is due to bone marrow involvement with the disease
- Women of childbearing potential must have a negative serum or urine beta human chorionic gonadotropin (beta-hCG) pregnancy test result within 7 days prior to the first dose of study drugs and must agree to use an effective contraception method during the study and for 30 days following the last dose of study drug; women of non- childbearing potential are those who are postmenopausal greater than 1 year or who have had a bilateral tubal ligation or hysterectomy; men who have partners of childbearing potential must agree to use an effective contraceptive method during the study and for 30 days following the last dose of study drug
