Summary
This phase I/Ib trial evaluates the best dose and side effects of ipilimumab in combination with either ibrutinib alone or with ibrutinib and nivolumab in treating patients with chronic lymphocytic leukemia (CLL) and Richter transformation (RT). Immunotherapy with monoclonal antibodies, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of cancer cells to grow and spread. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving ipilimumab with either ibrutinib alone or with ibrutinib and nivolumab may help control CLL and RT.

Criteria
Inclusion Criteria:

- Cohort 1: Patients with a diagnosis of CLL or SLL, refractory to and/or relapsed after
at least one prior therapy (prior therapy could be a chemoimmunotherapy regimen, or a
targeted therapy such as a BTK inhibitor, a BCL2 inhibitor, or a PI3 kinase inhibitor)
or untreated with del(17p) by fluorescence in situ hybridization (FISH) (high-risk
cytogenetics) and have an indication for treatment by International Workshop on
Chronic Lymphocytic Leukemia (IWCLL) 2008 criteria

- Cohort 2: Patients with a diagnosis of CLL or SLL who have been on ibrutinib for at
least 9 months with measurable persistent disease (absolute lymphocyte count [ALC] >
4K/uL, any lymph node > 1.5 cm by computed tomography [CT] scan, or > 30% lymphocytes
on bone marrow aspirate differential)

- Cohort 3: Patients with a diagnosis of RT

- Age 18 years or older

- Eastern Cooperative Oncology Group (ECOG) performance status =< 2

- Total bilirubin =< 1.5 x upper limit of normal (ULN). For patients with Gilbert's
disease, total bilirubin up to =< 3 x ULN is allowed provided normal direct bilirubin

- Serum creatinine =< 1.5 x ULN

- Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 3 x ULN (unless
deemed to be disease related)

- Females of childbearing potential must have a negative serum or urine beta human
chorionic gonadotrophin (beta-human chorionic gonadotropin [hCG]) pregnancy test
result within 14 days prior to the first dose of treatment and must agree to use an
effective contraception method during the study and for 23 weeks following the last
dose of the study drugs. Females of non-childbearing potential are those who are
postmenopausal greater than 1 year or who have had a bilateral tubal ligation or
hysterectomy. Males who have partners of childbearing potential must agree to use an
effective contraceptive method during the study and for 31 weeks following the last
dose of study drugs

- Patients or their legally authorized representative must provide written informed
consent

Exclusion Criteria:

- History of another primary invasive malignancy that has not been definitively treated
or in remission for at least 2 years. Patients with non-melanoma skin cancers or with
carcinomas in situ are eligible regardless of the time from diagnosis (including
concomitant diagnoses). If patients have another malignancy that was treated within
the last 2 years, such patients may be enrolled if the likelihood of requiring
systemic therapy for this other malignancy within 2 years is less than 10%, as
determined by an expert in that particular malignancy at MD Anderson Cancer Center and
after consultation with the principal investigator

- Any major surgery, radiotherapy, cytotoxic chemotherapy, biologic therapy,
immunotherapy, immunomodulatory drugs, experimental therapy within 4 weeks prior to
the first dose of the study drugs. Note: Prior therapy with anti CD20 monoclonal
antibody, anti CD52 monoclonal antibody, and lenalidomide are allowed. For oral
targeted therapies (such as idelalisib, venetoclax), a washout of 3 days is allowed.
For patients who are on ibrutinib at study entry - may continue ibrutinib without
interruption

- Significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias,
congestive heart failure, or myocardial infarction within 2 months of screening, or
any class 3 or 4 cardiac disease as defined by the New York Heart Association
Functional classification

- History of stroke or cerebral hemorrhage within 2 month

- Patients who have uncontrolled hypertension (defined as sustained systolic blood
pressure >= 140 mmHg or diastolic >= 90 mmHg)

- Known evidence of active cerebral/meningeal CLL. Patients may have history of central
nervous system (CNS) leukemic involvement if definitively treated with prior therapy
and no evidence of active disease at the time of registration

- Active, uncontrolled autoimmune hemolytic anemia or immune thrombocytopenia requiring
steroid therapy

- Patients with autoimmune diseases are excluded: Patients with a history of
inflammatory bowel disease (including Crohn's disease and ulcerative colitis) are
excluded from this study as are patients with a history of autoimmune disease (e.g.,
rheumatoid arthritis, systemic progressive sclerosis, systemic lupus erythematosus,
Wegener's granulomatosis)

- Patients with previous allogeneic stem cell transplant (SCT) within 6 months or with
active acute or chronic graft-versus host disease are excluded. Patients must be off
immunosuppression for graft versus host disease (GVHD) for at least 30 days before
cycle 1 day 1

- Patients with organ allografts (such as renal transplant) are excluded

- History of interstitial lung disease or pneumonitis

- Patients who are on high dose steroids (> 10 mg daily of prednisone or equivalent) or
immune suppression medications. Note: Patients on high-dose steroids (doses > 10
mg/day of prednisone or equivalent) or immune suppression medications are eligible
provided these drugs are discontinued at least 3 days prior to starting on the study
drugs

- Patients with uncontrolled active infection (viral, bacterial, and fungal) are not
eligible

- Current or chronic hepatitis B or C infection, or known seropositivity for human
immunodeficiency virus (HIV)

- Patient is pregnant or breast-feeding

- Concurrent use of investigational therapeutic agent

- Malabsorption syndrome or other condition that precludes enteral route of
administration

- Concomitant use of warfarin or other vitamin K antagonists

- Requires treatment with a strong cytochrome P450 (CYP) 3A inhibitor

- Other severe acute or chronic medical or psychiatric condition or laboratory
abnormality that in the opinion of the investigator may increase the risk associated
with study participation or investigational product administration or may interfere
with the interpretation of study results and/or would make the patient inappropriate
for enrollment into this study
