SAN FRANCISCO--(BUSINESS WIRE)--Bristol-Myers Squibb Company (NYSE: BMY) today announced at the American College of Rheumatology (ACR) Annual Scientific Meeting in San Francisco results from a 10-month study which showed that ORENCIA® (abatacept), compared to placebo, significantly improved multiple aspects of health-related quality of life (HRQoL): physical and psychosocial well being, pain and sleep quality in juvenile idiopathic arthritis (JIA) patients between the ages 6 and 17 years. These improvements with ORENCIA were maintained throughout the 10-month study period, during which the first four months included an open-label lead-in period and the last six months comprised a randomized, double-blind, placebo-controlled study.
