WALTHAM, Mass.--(BUSINESS WIRE)--Alkermes, Inc. (NASDAQ: ALKS) today announced that results from the phase 3 clinical study of VIVITROL® (naltrexone for extended-release injectable suspension) in opioid dependence have been published by The Lancet. The six-month, phase 3 trial met its primary endpoint and showed significantly greater opioid-free weeks among patients treated with VIVITROL, compared to placebo. VIVITROL is the first and only non-addictive, non-narcotic, once-monthly medication approved by the U.S. Food and Drug Administration (FDA) for the prevention of relapse to opioid dependence, following opioid detoxification. VIVITROL should be used along with psychosocial support such as counseling. In contrast to conventional agonist therapies that maintain stimulation of opioid receptors, VIVITROL is an opioid-blocking antagonist that, when administered once per month, occupies the opioid receptor, thereby helping to prevent patients from relapsing to opioid dependence.
