Array BioPharma Achieves Milestone for Selection of Second Clinical Candidate for MEK Anti-Cancer Program

- Array Receives $1,000,000 Milestone Payment from AstraZeneca -

BOULDER, Colo., Jan. 24 /PRNewswire-FirstCall/ -- Array BioPharma Inc. (Nasdaq: ARRY) and AstraZeneca PLC selected an additional clinical candidate for their small molecule anti-cancer program, triggering a $1 million milestone payment from AstraZeneca to Array. In December 2003, Array partnered the oncology portion of its MEK program, including its lead compound, ARRY-142886 (AZD6244), for co-development and commercialization with AstraZeneca. At that time, Array and AstraZeneca established a collaboration for research and development of additional clinical candidates.

"We are pleased that our collaboration with AstraZeneca has yielded an additional high quality development candidate," said Kevin Koch, Ph.D., President and Chief Scientific Officer, Array BioPharma. "Our first proprietary compound, ARRY-142886, continues to make good progress in Phase Ib. We believe the data generated in this study will support more advanced clinical testing of this promising compound."

About MEK Inhibition

MEK is a critical enzyme at the intersection of several biological pathways, which regulates cell proliferation and survival as part of the ras/raf/MEK/erk pathway. Constitutive activation of the ras/raf/MEK/erk pathway has been implicated in many cancers, including lung, pancreatic, colon, melanoma and thyroid caused by cancer-associated, mutational activation of B-raf and ras proteins. MEK inhibition is an attractive anti-cancer strategy as it has the potential to block inappropriate signal transduction regardless of the upstream position of the oncogenic aberration.
