Brief Summary:

The goal of this clinical research study is to learn how PCI-32765 (ibrutinib) may affect the life cycle of blood-cancer cells. Cancer cells will be "labeled" with heavy water to learn about their birth rates and death rates.

Ibrutinib is a type of drug called a kinase inhibitor. Kinases are proteins inside cells that help cells live and grow. The study drug is designed to inhibit or "block" the activity of a type of kinase that helps blood-cancer cells live and grow. By blocking the activity of this specific kinase, it is possible that the study drug may kill the cancer cells or stop them from growing.

Heavy water (2H2O) is a special type of water that is designed to help researchers learn how quickly cancer cells in the body reproduce.

Drug Information available for: Ibrutinib

Arm Intervention/treatment
Experimental: Heavy Water + PCI-32765
Subjects given 50ml 70% 2H2O (Heavy Water) 3 times a day for the first 5 days followed by 60 ml daily for a total of 4 weeks (labeling phase). Subjects given first dose in clinic. Subjects then given individual doses of 2H2O to consume at home; after the 5-day loading period, a 60 ml maintenance dose of 2H2O will be drunk at bedtime. At end of the 4th week, subjects stop drinking 2H2O (washout phase) and be followed from 6-12 weeks until beginning treatment with PCI-32765. PCI-32765 administered with 8 ounces (~240mL) of water at a dose of 420 mg (3 x 140mg capsules) orally once daily and continued daily. Treatment duration is 12 cycles, with each cycle consisting of 28 days.
Other: Heavy Water (2H2O)
50 ml 70% 2H2O 3 times a day for the first 5 days followed by 60 ml daily for a total of 4 weeks. After the 5-day loading period, a 60 ml maintenance dose of 2H2O will be drunk at bedtime. At end of the 4th week, subjects stop drinking 2H2O (washout phase) and be followed from 6-12 weeks until beginning treatment with PCI-32765.

Drug: PCI-32765
420 mg orally once daily.
Other Name: Ibrutinib




Primary Outcome Measures :
  1. Change in Leukemia Cell Death [ Time Frame: every three months, up to one year ]
    Stable isotopic labeling with deuterated water (2^H2O) to measure directly the effects of PCI-32765 (ibrutinib) on leukemia cell death in the peripheral blood of participants .


Secondary Outcome Measures :
  1. Percentage of Recently Born Leukemia Cells Mobilized Into the Blood by PCI-32765 Treatment [ Time Frame: every three months, up to one year ]
    Measurement of the fraction of recently born versus older leukemia cells in the peripheral blood of participants before and during PCI-32765 therapy, to determine the effects of PCI-32765 (ibrutinib) therapy on the birth rates of the leukemia cells.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. A diagnosis of CLL/ SLL and have not been previously treated.
  2. An indication for treatment by 2008 IWCLL Criteria.
  3. Male and female subjects of age >/= 18 years at the time of signing informed consent and requiring treatment within the next 2 to 6 months.
  4. Understand and voluntarily sign an informed consent, and be able to comply with study procedures and follow-up examinations.
  5. Platelet counts at study entry must be greater than 50,000/µL and absolute neutrophil counts at study entry must be greater than 750/µL.
  6. 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.
  7. Subjects must be able to contribute the required amount of blood and/or tissue without compromising their well-being or care and must weigh at least 110 pounds.
  8. Adequate renal and hepatic function as indicated by all of the following: total bilirubin </=1.5 x institutional Upper Limit of Normal (ULN); Aspartate Aminotransferase (AST) or Alanine Aminotransferase (ALT) </=2.5 x Upper limits of normal (ULN); and estimated creatinine clearance (CrCl) of > 30 mL/min, as calculated by the Cockcroft-Gault equation.
  9. Participants must be willing to be contacted again for consideration of additional studies in the future, such as a blood draw or another action (e.g., bone marrow aspiration and/or biopsy) that would be associated with their standard of care, unless they consented to such for research purposes.
  10. An Eastern Cooperative Oncology (ECOG)/World Health Organization (WHO) performance status of 0-2.
  11. Males and females of child bearing potential must have adequate birth control protection while on study and for 30 days after the last dose of study drug. The couple will use two forms of birth control for the entire time of the study and 30 days after finishing study. Conception control should include a hormonal method (birth control pill, etc.), and a double-barrier methods (condoms with spermicidal, sponge with spermicidal, or diaphragm with spermicidal), or abstinence (not having sex) will be practiced.
