I. To define the safety, tolerability and maximum tolerated dose (MTD) of lenalidomide when used in combination with ibrutinib in adults with relapsed or refractory chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL).
I. To determine the response rate and response duration in relapsed and refractory CLL/SLL patients with ibrutinib and lenalidomide.
II. To characterize the plasma pharmacokinetic (PK) interaction between ibrutinib and lenalidomide.
III. To explore whether pharmacogenetic studies can predict response, resistance or toxicity to ibrutinib and lenalidomide.
IV. To explore the ability of ibrutinib to occupy its targets (Bruton's tyrosine kinase [BTK] in B-cells and interleukin-2 inducible kinase [ITK] in T-cells), and whether co-administration with lenalidomide influences this binding.
V. To explore the early and late immunologic consequences of combining ibrutinib with lenalidomide in relapsed and refractory CLL.
VI. To explore the impact of ibrutinib and lenalidomide on ras homolog family member H (RhoH) expression and whether baseline RhoH expression predicts outcomes with this regimen.
VII. To explore mechanisms of resistance to ibrutinib. VIII. To explore the influence of traditional and new CLL/SLL clinical and laboratory prognostic factors on response to ibrutinib and lenalidomide.
OUTLINE: This is a dose-escalation study of lenalidomide.
Patients receive a run-up cycle of ibrutinib orally (PO) daily on days 1-28. Patients then receive ibrutinib PO and lenalidomide PO daily on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After 12 cycles, patients who have achieved complete remission (CR)/CR with incomplete marrow recovery (CRi), nodular partial remission (PR), partial remission with persistent lymphocytosis, partial remission, or who have stable disease discontinue lenalidomide and continue ibrutinib.
After completion of study treatment, patients are followed up for 90 days.

|Official Title:||A Dose Escalation Study of Ibrutinib With Lenalidomide for Relapsed and Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma|

Experimental: Treatment (ibrutinib and lenalidomide)
Patients receive a run-up cycle of ibrutinib PO daily on days 1-28. Patients then receive ibrutinib PO and lenalidomide PO daily on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After 12 cycles, patients who have achieved CR/CRi, nodular PR, partial remission with persistent lymphocytosis, partial remission, or who have stable disease discontinue lenalidomide and continue ibrutinib.
- Maximum tolerated dose of lenalidomide when combined with ibrutinib [ Time Frame: 28 days ]Defined as the highest dose in which less than or equal to 1/6 patients have dose limiting toxicity. Assessed using National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. All patient safety information collected will be summarized using descriptive statistics (number of non-missing values, mean, median, standard deviation, minimum and maximum) for continuous variables and counts and percentages for categorical variables, where applicable.
- Response rates [ Time Frame: Up to 12 months ]Response rates will be calculated based on all the intention-to-treat subjects and reported along with its exact 95% confidence interval.
- Remission/response duration [ Time Frame: Up to 90 days ]Remission/response duration is measured from the time measurement criteria are met for complete response or partial response (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented. Response duration will be calculated, and the mean, median, minimum, and maximum values will be reported.
- Non-compartmental areas under the curve (AUCs) for ibrutinib [ Time Frame: Up to day 1 of cycle 2 ]The impact of lenalidomide on pharmacokinetics of ibrutinib will be evaluated by comparisons of non-compartmental AUCs for ibrutinib on cycle 0, day 8 versus cycle 2, day 1.
- Ability of ibrutinib to bind to its targets [ Time Frame: Up to day 1 of cycle 2 ]The impact of lenalidomide on ibrutinib binding to Bruton's tyrosine kinase and interleukin-2 inducible kinase will be evaluated, and the mechanistic interactions between the two agents will be investigated.
- Percentage of occupancy [ Time Frame: Up to day 1 of cycle 2 ]Defined as the ratio between the signal pre-dose and the signal post-dose. More than 95% occupancy is defined as full occupancy.
- Change in Rho guanosine triphosphate (GTP)ase levels [ Time Frame: Baseline to up to day 1 of cycle 2 ]Comparison of Rho GTPase expression and activation levels, as well as migration before and after treatment with lenalidomide, will be performed using a paired Student t test. The predictive power of the clinical and laboratory values measured for purposes of biomarker discover will be assessed by a multiple comparison analysis of variance test.
