Phase 2 Study of the Combination of Bruton's Tyrosine Kinase Inhibitor PCI-32765 and Rituximab in High-Risk Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma Patients
A Phase 2 Study of the Combination of the Bruton's Tyrosine Kinase Inhibitor PCI-32765 and Rituximab in High-Risk Chronic Lymphocytic Leukemia (CLL) and Small Lymphocytic Lymphoma (SLL) Patients
The goal of this clinical research study is to learn if PCI-32765 (Ibrutinib) combined with rituximab can help to control CLL and SLL. The safety of this combination will also be studied.
Ibrutinib is designed to stop a protein from working in the cells, which may cause the cancer cells to die or stop growing.
Rituximab is designed to attach to cancer cells and damage them, which may cause the cells to die.
Study Overview
Detailed Description
Study Drug Administration:
If you are found to be eligible to take part in this study, you will receive rituximab by vein on Days 1, 8, 15, and 22 of Cycle 1 (+ 3 days) and then on Day 1 (+/- 7 days) of Cycles 2-6.
Each cycle is 28 days.
You will take Ibrutinib capsules by mouth 1 time each day starting on Day 2 of Cycle 1. You should take it with 1 cup (8 ounces) of water.
You will also take allopurinol by mouth 1 time each day during the first 1-2 weeks of study treatment to lower the risk of side effects.
Study Visits:
On Days 7, 14, 21, and 28 of Cycle 1 (+/- 3 days):
- You will have a physical exam, including measurement of your vital signs.
- Blood (about 1 tablespoon) will be drawn for routine tests.
- You will be asked about any drugs you may be taking.
At the end of Cycles 2, 3, 4, 6, 9, and 12 (+/- 1 month):
- You will have a physical exam, including measurement of your vital signs.
- Blood (about 1 tablespoon) will be drawn for routine tests.
- You will be asked about any drugs you may be taking.
At the end of Cycles 3 or 6, and 12 (+/- 1 month), and then every 12 cycles (+/- 1 month) after that if the doctor thinks it is needed, you will have CT scans of the chest, abdomen and pelvis to check the status of the disease.
At the end of Cycles 3, 6, and 12 and then every 12 cycles (+/- 1 month) after that, you will have a bone marrow aspiration to check the status of the disease. If the doctor things these bone marrow aspirations are no longer needed, you will no longer have to have them.
Every 3 months (+/- 1 month) for Cycles 13-36 and every 6 months (+/- 1 month) after that:
- You will have a physical exam, including measurement of your vital signs.
- Blood (about 1 tablespoon) will be drawn for routine tests.
- You will be asked about any drugs you may be taking.
Length of Treatment:
You may continue taking the study drug combination of rituximab and Ibrutinib for up to 6 cycles, after which Ibrutinib will be continued for up to a total of 12 cycles. It will be possible to continue with Ibrutinib treatment beyond 12 cycles if the study doctor thinks it is in your best interest. You will no longer be able to take the study drug if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.
This is an investigational study. Ibrutinib is FDA approved and commercially available for the treatment of patients with mantle cell lymphoma, CLL and SLL. Its use in this study is investigational. Rituximab is FDA approved to treat CLL and SLL.
Up to 40 patients will take part in this study. All will be enrolled at MD Anderson.

Description
Inclusion Criteria:
- 1.Patients must have a diagnosis of high-risk CLL/SLL and be previously treated with up to 3 lines of prior therapy. High-risk CLL and high-risk SLL is defined by the presence of a 17p deletion or 11q deletion or TP53 mutation. Any CLL and SLL patient who has a short remission duration of less than 3 years after prior first-line chemo-immunotherapy, such as the FCR regimen, also fulfills criteria of high-risk CLL/SLL, regardless of the presence or absence of cytogenetic abnormalities.
- 2.CLL and SLL patients with 17p deletion or TP53 mutation will not be required to have received any prior therapy, given the poor outcome of CLL/SLL patients to standard frontline chemo-immunotherapy, such patients will be eligible if they are untreated or if they have received up to 3 lines of prior therapy.
- Patients must have an indication for treatment by 2008 IWCLL Criteria.
- Patients age > 18 years at the time of signing informed consent. Understand and voluntarily sign an informed consent. Be able to comply with study procedures and follow-up examinations.
- Eastern Cooperative Oncology Group (ECOG)/World Health Organization (WHO) performance status of 0-1.
- Patients of childbearing potential must be willing to practice highly effective birth control (e.g., condoms, implants, injectables, combined oral contraceptives, some intrauterine devices [IUDs], sexual abstinence, or sterilized partner) during the study and for 30 days after the last dose of study drug. Women of childbearing potential include any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not postmenopausal. Post menopause is defined as follows: Amenorrhea >/= 12 consecutive months without another cause and a documented serum follicle stimulating hormone (FSH) level >35 mIU/mL; a male of childbearing potential is any male that has not been surgically sterilized.
- Adequate renal and hepatic 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 who will be allowed to participate; an Alanine (ALT) </=2.5 x ULN; and an estimated creatinine clearance (CrCl) of > 30 mL/min, as calculated by the Cockcroft-Gault equation unless disease related.
- Free of prior malignancies for 3 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma in situ of the cervix or breast.
- A Urine Pregnancy Test (within 7 days of Day 1) is required for women with childbearing potential
Exclusion Criteria:
- Pregnant or breast-feeding females.

- Any other severe concurrent disease, or have a history of serious organ dysfunction or disease involving the heart, kidney, liver or other organ system that may place the patient at undue risk to undergo therapy with PCI-32765 and rituximab.
- Significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of screening, or any Class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification.
- Significant screening ECG abnormalities including left bundle branch block, 2nd degree AV block type II, 3rd degree block, bradycardia, and QTc > 470 msec.
- Any serious medical condition, laboratory abnormality, or psychiatric illness that places the subject at unacceptable risk if he/she were to participate in the study.
- History of stroke or cerebral hemorrhage within 6 months.
- Evidence of bleeding diathesis or coagulopathy.
