Pembrolizumab Alone or With Idelalisib or Ibrutinib in Treating Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia or Other Low-Grade B-Cell Non-Hodgkin Lymphomas

Inclusion Criteria:

CLL/SLL PATIENTS (ARM A) ONLY

Diagnosis of CLL according to the National Cancer Institute (NCI) criteria or SLL according to the World Health Organization (WHO) criteria; this includes previous documentation of:

Biopsy-proven small lymphocytic lymphoma or

Diagnosis of CLL according to NCI working group criteria as evidenced by all of the following:

Peripheral blood B cell count of > 5 x 10^9/L consisting of small to moderate size lymphocytes

Immunophenotyping consistent with CLL defined as:

The predominant population of lymphocytes share both B-cell antigens (cluster of differentiation [CD]19, CD20 [typically dim expression] or CD23) as well as CD5 in the absence of other pan-T-cell markers (CD3, CD2, etc.)
Clonality as evidenced by kappa or lambda light chain expression (typically dim immunoglobulin expression) or other genetic method (e.g. immunoglobulin heavy chain variable [IGHV] analysis)
NOTE: splenomegaly, hepatomegaly, or lymphadenopathy are not required for the diagnosis of CLL
Before diagnosing CLL or SLL, mantle cell lymphoma must be excluded by demonstrating a negative fluorescent in situ hybridization (FISH) analysis for t(11;14) (immunoglobulin H [IgH]/cyclin D1 [CCND1]) on peripheral blood or tissue biopsy or negative immunohistochemical stains for cyclin D1 on involved tissue biopsy

Patients must be previously treated with at least one prior line of therapy; EXCEPTION: CLL patients with Richter's transformation or Hodgkin transformation do not need prior therapy to enroll

NOTE:

Prior chemotherapy or biologic novel therapy or anti-cancer monoclonal antibody based therapy for treatment of CLL will be considered prior therapy; nutraceutical treatments with no established benefit in CLL (such as epigallocatechin gallate or EGCG, found in green tea or other herbal treatments) will not be considered "prior treatment"
Prior oral corticosteroid therapy for an indication other than CLL will not be considered "prior treatment"
Previous use of corticosteroids in the combination with other therapy for treatment of autoimmune complications of CLL does constitute prior therapy for CLL

CLL/SLL patients must have progressive disease with any one of the following characteristics based on standard criteria for treatment as defined by the NCI-Working Group (WG) 1996
