NORTH CHICAGO, Ill., October 28, 2015 - AbbVie (NYSE: ABBV), a global biopharmaceutical company, announced today that IMBRUVICA® (ibrutinib) was awarded the prestigious Prix Galien 2015 Award for Best Pharmaceutical Agent. IMBRUVICA won this distinction out of 24 category nominees, all of which were deemed innovative in the field of medicine and were approved by the U.S. Food and Drug Administration (FDA) within the past five years. IMBRUVICA is jointly developed and commercialized by Pharmacyclics LLC, an AbbVie Company and Janssen Biotech, Inc.

"We are honored that IMBRUVICA, a first-in-class, oral therapy has been recognized by the Prix Galien USA Committee for the role it continues to play in treating patients with certain blood cancers," said Erik von Borcke, President of Pharmacyclics. "Our goal is to continue developing clinically meaningful, scientifically sound therapies that offer healthcare professionals and their patients the opportunity at the best possible outcome, allowing them to resume as normal a life as possible."

Considered to be the biomedical industry's highest accolade, the Prix Galien Award recognizes outstanding achievement in the development of new therapies. The Prix Galien was created in France in 1970 in honor of Galen, the father of medical science and modern pharmacology. Worldwide, the Prix Galien Award is generally regarded as the equivalent of the Nobel Prize in biopharmaceutical and medical technology research.

About IMBRUVICA

IMBRUVICA (ibrutinib) is currently approved for the treatment of patients with chronic lymphocytic leukemia (CLL) who have received at least one prior therapy, all CLL patients who have del 17p and patients with Waldenström's macroglobulinemia.1 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. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trials.1

IMBRUVICA is a first-in-class, oral, once-daily therapy that inhibits a protein called Bruton's tyrosine kinase (BTK).1 IMBRUVICA was one of the first medicines to receive U.S. FDA approval via the new Breakthrough Therapy Designation pathway, and is currently the only product to have received three Breakthrough Therapy Designations.

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 being studied alone and in combination with other treatments in several blood cancers. More than 6,100 patients have been treated in clinical trials of IMBRUVICA conducted in 35 countries by more than 800 investigators.
