Array BioPharma 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 (CTX I) degradation were assessed. ARRY 797 treatment resulted in statistically significant decreases in COMP and CTX I at week 4 (decreases of 10% and 38% versus placebo, respectively). The decrease in CTX I was sustained and returned to baseline by the follow up visit. The abstract concludes that further evaluation of the potential for disease modifying activity is warranted.
