简要总结
The standard approach to managing chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL) is to wait until you have symptoms before treatment is given.
The goal of this clinical research study is to learn if providing earlier treatment for CLL or SLL with ibrutinib in patients who do not have symptoms will be more effective than waiting until symptoms develop.
This is an investigational study. Ibrutinib is FDA approved and commercially available for the treatment of patients with CLL or SLL. It is considered investigational to give ibrutinib to CLL and SLL patients before symptoms develop.
The study doctor can describe how the study drug is designed to work.
Up to 50 participants will be enrolled in this study. All will take part at MD Anderson.
详细描述
Study Drug Administration:
If you are found to be eligible to take part in this study, you will take ibrutinib by mouth 1 time every day. Each dose should be taken with about 1 cup (8 ounces) of water.
If you miss a dose of ibrutinib, it can be taken as soon as possible on the same day. You should take your next dose as scheduled. If you forget to take a dose, do not take extra capsules on the next day to "make up" the missed dose.
You will be given standard drugs, such as allopurinol or valacyclovir, to help decrease the risk of side effects. You may ask the study staff for information about how the drugs are given and their risks. If you have side effects, your dose of ibrutinib may be lowered or temporarily stopped until you recover from the side effects.

- •ECOG performance status of 0-2
- •Male and female subjects who agree to use both a highly effective method of birth control (eg, implants, injectables, combined oral contraceptives, some intrauterine devices [IUDs], complete abstinence , or sterilized partner) and a barrier method (eg., condoms, vaginal ring, sponge, etc) during the period of therapy and for 30 days after the last dose of study drug for females and 90 days for males. OR Female subjects who are of non-reproductive potential (ie, post-menopausal by history - no menses for >/=1 year; OR history of hysterectomy; OR history of bilateral tubal ligation; OR history of bilateral oophorectomy)
- •Adequate hepatic and renal 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 or of non-hepatic origin who will be allowed to participate, provided bilirubin is </=3 x institutional ULN; an ALT </=2.5 x ULN; and estimated creatinine clearance (CrCl) of > 30 mL/min, as calculated by the Cockcroft- Gault equation.
- •PT/INR <1.5 x ULN and PTT (aPTT) <1.5 x ULN (unless abnormalities are unrelated to coagulopathy or bleeding disorder).
- •Free of prior malignancies for 3 years with exception of patients diagnosed with basal cell or non-metastatic squamous cell carcinoma of the skin, or carcinoma in situ of the cervix or breast, who are eligible even if they are currently treated or were treated and/or diagnosed in the past 3 years prior to study enrolment
- •Diagnosis of CLL/SLL that meets IWCLL diagnostic criteria
排除标准
- •Receipt of any prior therapy for CLL. Patients who have received "early intervention" with INVAC-1 vaccine against hTERT will be eligible provided all of the following exist: i) They had no response to the vaccine treatment (persistent CLL >1% in bone marrow). ii) ≥3 months have elapsed since the last dose of vaccine. iii) No residual toxicities attributable to the vaccine exist at the time of study enrollment. iv) The patient does not meet IWCLL criteria for requiring treatment.
- •Richter Transformation
- •Active malignancy requiring systemic therapy, other than CLL, with the exception of: adequately treated in situ carcinoma of the cervix uteri; adequately treated basal cell carcinoma or localized squamous cell carcinoma of the skin; previous malignancy confined and surgically resected (or treated with other modalities) with curative intent.
- •Systemic anticoagulation with warfarin or other Vitamin K antagonists
- •Active and uncontrolled autoimmune hemolytic anemia (AIHA) or autoimmune thrombocytopenia (ITP) requiring daily prednisone dose of >/=20 mg
- •Current and concurrent use of strong CYP3A4 inhibitors or inducers
- •Pregnant or breast-feeding females
- •Uncontrolled and active systemic fungal, bacterial, viral, or other infection (defined as exhibiting ongoing signs/symptoms related to the infection and without improvement, despite appropriate antibiotics or other treatment)
- •Any other severe concurrent disease, or history of serious organ dysfunction or disease involving the heart, kidney, liver or other organ system that, in the investigator's opinion, may place the patient at undue risk to undergo therapy with ibrutinib
- •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
