Chronic Lymphocytic Leukemia Clinical Trial
PCI-32765 (Ibrutinib) in Treating Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, or B-cell Prolymphocytic Leukemia
This is a Phase II, single institution open-label, non-randomized monotherapy study to evaluate the clinical efficacy and durable disease control of PCI-32765 administered to patients with relapsed/refractory leukemia-cll/" >CLL/SLL/PLL of all risk categories with patients having deletion 17p13 independently evaluated.
This is a clinical trial, a type of research study, involving treatment with an investigational (experimental) drug called PCI-32765 (Ibrutinib), a "kinase inhibitor". "Kinases" are proteins that are inside of cells and help them to live and grow. The specific kinase inhibited or blocked by this study drug is believed to help blood cancer cells grow and live. By inhibiting or "blocking" the activity of this kinase, it is possible that the study drug may be able to kill the cancer cells or stop them from growing. This study will involve treating patients with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), or B-cell prolymphocytic leukemia (B-PLL) that has not responded to or has relapsed after standard treatment. This trial is studying how effective PCI-32765 is at treating CLL, SLL, or B-PLL and all the effects, good and/or bad, treatment with this drug has on patients and their cancers.
Confirmed diagnosis of relapsed/refractory CLL/SLL who require treatment and have failed at least one prior therapy.
Patients must have available results of interphase cytogenetics CLL fluorescent in situ hybridization (FISH) panel; the cytogenetic analysis must be done prior to starting therapy but after any recent therapy

Patients with uncontrolled or active infection requiring antibiotic therapy; patients with controlled infections who are receiving extended antibiotics or prophylactic therapy are not excluded
Patients who have had chemotherapy, radiotherapy or immunotherapy within 4 weeks prior to the first dose of study drug (corticosteroids for disease-related symptoms allowed but doses equivalent to > 20 mg prednisone orally per day require 1 week washout before study drug administration or steroid dose must be equal to =< 20 mg prednisone orally daily)
