New pre-clinical, clinical data for IMBRUVICA to be highlighted at AACR Annual Meeting

Pharmacyclics, Inc. (NASDAQ: PCYC) today announced that new pre-clinical and clinical data for ibrutinib (IMBRUVICA®) will be highlighted at the 2015 American Association for Cancer Research (AACR) Annual Meeting to be held April 18 – 22, 2015, in Philadelphia, PA. Several company-sponsored and investigator-initiated abstracts have been accepted for presentation as oral and poster sessions highlighting data in solid tumor and blood cancers. IMBRUVICA is jointly developed and commercialized by Pharmacyclics and Janssen Biotech, Inc.

"We are very encouraged by the ibrutinib data we are seeing both as a single agent and as a synergistic combination with other treatment options across solid tumor and new hematologic histologies," said Betty Chang, Ph.D., Head of Research at Pharmacyclics. "Based on the success to date within ibrutinib's approved and investigational uses, we remain committed to exploring the further potential of ibrutinib as a backbone of therapy within the broader oncology and hematology arenas."

A select list of accepted ibrutinib abstracts is included below. A full list of accepted ibrutinib data abstracts is available on the AACR website.
