SUNNYVALE, Calif., Dec. 22, 2014 /PRNewswire/ -- Pharmacyclics, Inc. (NASDAQ: PCYC) announced today that the U.S Food and Drug Administration (FDA) has provided a Prescription Drug User Fee Act (PDUFA) target date of April 17, 2015 by which time the FDA is planning to finalize its review of a supplemental New Drug Application (sNDA) for IMBRUVICA (ibrutinib) as a treatment for patients with Waldenstrom's macroglobulinemia (WM). IMBRUVICA is being jointly developed and commercialized by Pharmacyclics and Janssen Biotech, Inc.

About IMBRUVICA^®
IMBRUVICA (ibrutinib) is a first-in-class, oral, once-daily therapy that inhibits a protein called Bruton's tyrosine kinase (BTK).¹ BTK is a key signaling molecule in the B-cell receptor signaling complex that plays an important role in the survival and spread of malignant B cells.^1,2 IMBRUVICA blocks signals that tell malignant B cells to multiply and spread uncontrollably.¹

IMBRUVICA is approved for the treatment of patients with chronic lymphocytic leukemia (CLL) who have received at least one prior therapy, and for the treatment of CLL patients with del 17p,¹ a genetic mutation that occurs when part of chromosome 17 has been lost.

IMBRUVICA is also approved for the treatment of patients with mantle cell lymphoma (MCL) who have received at least one prior therapy. Accelerated approval was granted for the MCL indication based on overall response rate (ORR). Improvements in survival or disease-related symptoms have not been established. Continued approval for the MCL indication may be contingent upon verification of clinical benefit in confirmatory trials.¹

IMBRUVICA is being studied alone and in combination with other treatments in several blood cancers. Over 4,600 patients have been treated in clinical trials of IMBRUVICA conducted in 35 countries by more than 800 investigators. Currently, 13 Phase III trials have been initiated with IMBRUVICA and 55 trials are registered on ClinicalTrials.gov. The overall clinical development program in CLL currently includes seven Phase III trials and covers all lines of therapy and various combinations of treatments.

IMBRUVICA was one the first medicines to receive U.S. FDA approval via the new Breakthrough Therapy Designation pathway, and is the only product to have received three Breakthrough Therapy Designations.
