A Phase II Study of Ibrutinib Plus FCR in Previously Untreated, Younger Patients With Chronic Lymphocytic Leukemia

Running, not enrolling · Phase 2

Conditions studied: Chronic Lymphocytic Leukemia, Leukemia

In brief

This research study is evaluating a new drug called ibrutinib in combination with the standard drugs fludarabine, cyclophosphamide, and rituximab (FCR) as a possible treatment for Chronic Lymphocytic Leukemia (CLL).

You may qualify if…

• Must have a confirmed diagnosis of chronic lymphocytic leukemia or small lymphocytic lymphoma. as per IW-CLL 2008 criteria. Patients must also require therapy for that diagnosis, based on meeting at least one of the following criteria:
• evidence of progressive marrow failure as manifested by the development of, or worsening of, anemia (hemoglobin <11.0 g/L) and/or thrombocytopenia (platelets <100 x 10\^9/L)
• massive (≥ 6 cm below the left costal margin), progressive, or symptomatic splenomegaly
• massive nodes (at least 10 cm longest diameter), progressive, or symptomatic lymphadenopathy
• progressive lymphocytosis with an increase of more than 50% over a 2-month period or LDT of <6 months. Lymphocyte doubling time may be obtained by linear regression extrapolation of absolute lymphocyte counts obtained at intervals of 2 weeks over an observation period of 2 to 3 months. In subjects with initial blood lymphocyte counts of <30 x 10\^9/L, LDT should not be used as a single parameter to define indication for treatment. In addition, factors contributing to lymphocytosis or lymphadenopathy other than CLL (eg, infections) should be excluded
• autoimmune anemia and/or thrombocytopenia that is poorly responsive to corticosteroids or other standard therapy
• documented constitutional symptoms, defined as 1 or more of the following disease-related symptoms or signs:
• unintentional weight loss >10% within 6 months prior to screening
• significant fatigue (inability to work or perform usual activities)
• fevers >100.5° F or 38.0° C for 2 or more weeks prior to screening without evidence of infection
• night sweats for more than 1 month prior to screening without evidence of infection
• No prior CLL-directed therapy that was instituted due to patient previously meeting IW-CLL 2008 criteria for treatment
• Age greater than or equal to 18 years and less than or equal to 65. Because CLL is extremely rare in persons <18 years of age, children are excluded from this study. Because iFCR is an aggressive therapy that is likely to be less well-tolerated even in fit elderly subjects, persons > 65 years of age are excluded
• ECOG performance status ≤ 1
• Adequate hematologic function independent of growth factor support for at least 7 days prior to screening and randomization, with the exception of pegylated G-CSF (pegfilgrastim) and darbepoetin which cannot be administered within 14 days of screening.
• Patients must meet the following hematologic criteria at screening:
• Absolute neutrophil count ≥ 750 cells/mm3 (0.75 x 109/L).
• Platelet count ≥ 50,000 cells/mm3 (50 x 109/L).
• Hemoglobin ≥ 8 g/L - Adequate hepatic and renal function defined as:
• Serum aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 3.0 x upper limit of normal (ULN)
• Bilirubin ≤ 1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin)
• Adequate renal function defined by serum creatinine >1.5 x ULN
• PT/INR <1.5 x ULN and PTT (aPTT) <1.5 x ULN.
• The effects of ibrutinib on the developing human fetus are unknown. For this reason and because similar agents are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation.

You may not qualify if…

• Concurrent Conditions:
• History of other malignancies, except:
• Malignancy treated with curative intent and with no known active disease present for ≥ 3 years before the first dose of study drug and felt to be at low risk for recurrence by treating physician.
• Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease.
• Adequately treated carcinoma in situ without evidence of disease.
• Concurrent systemic immunosuppressant therapy (eg, cyclosporine A, tacrolimus, etc., or chronic administration of >20 mg/day of prednisone) within 28 days of the first dose of study drug.
• Vaccinated with live, attenuated vaccines within 4 weeks of first dose of study drug.
• Recent infection requiring systemic treatment that was completed ≤ 14 days before the first dose of study drug.
• Known bleeding disorders (eg, von Willebrand's disease) or hemophilia.
• History of stroke or intracranial hemorrhage within 6 months prior to enrollment.
• Known history of human immunodeficiency virus (HIV) or active with hepatitis C virus (HCV) or hepatitis B virus (HBV). Patients who are positive for hepatitis B core antibody or hepatitis B surface antigen must have a negative polymerase chain reaction (PCR) result before enrollment. Those who are PCR positive will be excluded.
• Any uncontrolled active systemic infection.
• Major surgery within 4 weeks of first dose of study drug.
• Any life-threatening illness, medical condition, or organ system dysfunction that, in the investigator's opinion, could compromise the subject's safety or put the study outcomes at undue risk.
• Currently active, clinically significant cardiovascular disease, such as uncontrolled arrhythmia or Class 3 or 4 congestive heart failure as defined by the New York Heart Association Functional Classification; or a history of myocardial infarction, unstable angina, or acute coronary syndrome within 6 months prior to randomization.
• Unable to swallow capsules or malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel, symptomatic inflammatory bowel disease or ulcerative colitis, or partial or complete bowel obstruction.
• Lactating or pregnant.
• Patients receiving any other study agents
• Patients with known CNS involvement
• Baseline QTcF >480 ms. NOTE: This criterion does not apply to patients with a left bundle branch block.
• Patients who require warfarin or other vitamin K antagonists for anticoagulation (other anticoagulants are allowed after consultation with the Principal Investigator).
• Concurrent administration of medications or foods that are strong inhibitors or inducers of CYP3A
• Patients with ongoing use of prophylactic antibiotics are eligible as long as there is no evidence of active infection and the antibiotic is not included on the list of prohibited medications
• Significant co-morbid condition or disease which in the judgment of the Principal Investigator would place the patient at undue risk or interfere with the study
• Unable to receive prophylactic treatment for pneumocystis
