Array BioPharma, Inc. to Present Clinical Data on ARRY-797 at the 2012 American College of Rheumatology Annual Meeting

BOULDER, Colo., Nov. 6, 2012 /PRNewswire/ -- Array BioPharma Inc. (NASDAQ: ARRY) announced that an abstract discussing the final Phase 2 trial results with ARRY-797 in patients with osteoarthritis pain will be presented at the 2012 American College of Rheumatology Annual Meeting in Washington, D.C. This abstract includes data on ARRY-797's analgesic effect and markers of disease modification. In addition, biomarkers of cartilage (COMP) and bone (CTXI) degradation were assessed. ARRY797 treatment resulted in statistically significant decreases in COMP and CTXI at week 4 (decreases of 10% and 38% versus placebo, respectively). The decrease in CTXI was sustained and returned to baseline by the followup visit. The abstract concludes that further evaluation of the potential for disease modifying activity is warranted.

Array announced in July 2012 that ARRY-797, a non-opioid, met its primary endpoint in a randomized, placebo-controlled and active-controlled (oxycodone ER) Phase 2 clinical trial in 157 osteoarthritis patients suffering from moderate to severe knee pain despite the use of non-steroidal anti-inflammatory drugs (NSAIDs). Patients in all treatment groups continued using NSAIDs throughout the trial. ARRY-797 is a novel, oral, selective p38 inhibitor with a mechanism of action unique from that of currently approved pain medications. Given our internal focus on hematology/oncology, Array is in active discussions with potential partners to maximize the value of this drug.
