Alkermes and Cephalon Receive FDA Approval of Vivitrol(TM) for the Treatment of Alcohol DependenceFirst, Once-Monthly Injectable Medication Provides New Treatment Option
Companies to Host Conference Call at 4:30 p.m. EDT
CAMBRIDGE, Mass. and FRAZER, Pa.--(HSMN NewsFeed)--April 13, 2006--Alkermes, Inc., (Nasdaq: ALKS ) and Cephalon, Inc., (Nasdaq: CEPH ) today announced that the U.S. Food and Drug Administration (FDA) has approved VIVITROL(TM) (naltrexone for extended-release injectable suspension) for the treatment of alcohol dependence. VIVITROL, the first and only once-monthly injectable medication for alcohol dependence, is indicated for alcohol dependent patients who are able to abstain from drinking in an outpatient setting and are not actively drinking when initiating treatment. Treatment with VIVITROL should be used in combination with psychosocial support, such as counseling or group therapy.
Alcohol dependence is a serious and chronic disease that affects multiple regions of the brain, providing rationale for the use of medication with psychosocial support as part of an integrated treatment plan. Of the more than 18 million Americans who abuse or are dependent on alcohol,(1) approximately 2.2 million seek treatment for their alcohol problems.(2) More than 75% of these patients relapse back to drinking within the first year of beginning treatment using currently available treatment approaches.(3) A VIVITROL injection provides medication over one month, therefore, patients do not need to make a decision to take their medication every day.
"VIVITROL is the first once-a-month medication for alcohol dependence that ensures patients get the benefit of medication over the entire month," stated Richard Rosenthal, M.D., Chairman, Department of Psychiatry, St. Luke's-Roosevelt Hospital Center, New York, and Professor of Clinical Psychiatry, Columbia University College of Physicians and Surgeons. "With VIVITROL, physicians have a new option to help treat patients with alcohol dependence, and patients have new hope to help them in their battle with this devastating disease."
VIVITROL works by binding to opioid receptors in the brain. Although the mechanism responsible for the reduction in alcohol consumption observed with VIVITROL treatment is not entirely understood, preclinical data suggests that occupation of the opioid receptors results in the blockade of the neurotransmitters in the brain that are believed to be involved with alcohol dependence. This blockade may result in the reduction in alcohol consumption observed in patients treated with VIVITROL.
"The approval of VIVITROL, our first internally developed product, marks a significant milestone for Alkermes and demonstrates the potential of our proprietary extended-release technology to offer patients an entirely new way to get the medication they need," stated Richard Pops, CEO of Alkermes. "Together with Cephalon, we are committed to bringing forward VIVITROL as an exciting new treatment option for millions of people struggling with alcohol dependence."
"VIVITROL will be a major new product in our CNS portfolio and represents an exciting opportunity to assist in the treatment of this complex and chronic disease," said Robert P. Roche, Jr., Executive Vice President, Worldwide Pharmaceutical Operations at Cephalon. "We understand this market and its significant unmet needs and are ready to launch VIVITROL as a new treatment option to meet those needs."
Cephalon and Alkermes expect VIVITROL to be available to physicians and patients in the United States by the end of June 2006. VIVITROL will be available as a single dose 380 mg intramuscular injection.
Based on a joint commercialization agreement signed in June 2005, Cephalon has primary responsibility for the marketing and sales of VIVITROL and Alkermes is responsible for manufacturing VIVITROL. Under the terms of the agreement, Alkermes receives a milestone payment of $110 million from Cephalon upon the FDA approval.
The efficacy of VIVITROL was studied in a six-month Phase III double-blind, placebo-controlled, randomized clinical trial of alcohol dependent patients. The primary endpoint of the study was the reduction in the event rate of heavy drinking days, and heavy drinking was defined as five or more drinks per day for men and four or more drinks per day for women. In the overall study population, patients treated with VIVITROL 380 mg and psychosocial support demonstrated a greater reduction in days of heavy drinking than those treated with only psychosocial support and placebo injection over the six-month treatment period. In a subset of patients who abstained from drinking in the week prior to receiving their first dose of medication, those treated with VIVITROL 380 mg were more likely to maintain complete abstinence (without relapse) and showed a greater reduction in drinking days, as well as a greater reduction in heavy drinking days, compared to the placebo-treated group over the six-month treatment period.
Important Safety Information
In clinical trials, VIVITROL was generally well tolerated and the majority of adverse events were mild to moderate in intensity. The most common adverse events associated with VIVITROL clinical trials were nausea, vomiting, headache, dizziness, fatigue and injection site reactions.
Naltrexone has the capacity to cause hepatocellular injury when given in excessive doses. Naltrexone is contraindicated in acute hepatitis or liver failure, and its use in patients with active liver disease must be carefully considered in light of its hepatotoxic effects. The margin of separation between the apparently safe dose of naltrexone and the dose causing hepatic injury appears to be only five-fold or less. VIVITROL does not appear to be a hepatotoxin at the recommended doses. Patients should be warned of the risk of hepatic injury and advised to seek medical attention if they experience symptoms of acute hepatitis. Use of VIVITROL should be discontinued in the event of symptoms and/or signs of acute hepatitis.
VIVITROL is contraindicated in patients receiving opioid analgesics, with current physiologic dependence on opioids, in acute opioid withdrawal or who have previously exhibited hypersensitivity to naltrexone, PLG or any other components of the diluent.
VIVITROL is a potent opioid antagonist. Patients must be opioid free for a minimum of seven to 10 days before starting VIVITROL treatment. Any attempt to overcome the opioid blockade produced by VIVITROL using exogenous opioids may result in fatal overdose. In patients with a previous history of opioid abuse, administration of exogenous opioids may result in potentially life-threatening opioid intoxication. When reversal of VIVITROL blockade is required for pain management, patients should be monitored in a setting equipped and staffed for cardiopulmonary resuscitation.
Should a patient receiving VIVITROL develop progressive dyspnea and hypoxemia, the diagnosis of eosinophilic pneumonia should be considered. Patients should be advised to seek medical attention for injection site reactions such as pain, tenderness, induration or pruritus that do not improve within one month following the injection. Alcohol dependent patients, including those taking VIVITROL, should be monitored for the development of depression or suicidal thinking.

VIVITROL is the first and only extended-release medication for the treatment of alcohol dependence. It is a once-monthly, intramuscular injectable medication indicated for patients who are able to abstain from drinking alcohol in an outpatient setting prior to beginning treatment. VIVITROL, which is non-addictive and non-aversive, is administered by a healthcare provider and should be used in combination with psychosocial support. The proprietary Medisorb® drug delivery technology in VIVITROL enables the medication to be gradually released into the body at a controlled rate over a one-month time period.
About Alcohol Dependence
Alcohol dependence is a chronic disease with underlying neurological and genetic factors.(4) The four symptoms most commonly associated with alcohol dependence are cravings, loss of control over drinking, withdrawal symptoms (including sweating, nausea, shakiness and anxiety) and an increased tolerance for alcohol.(5) Approximately 18 million people in the U.S. are dependent on or abuse alcohol; half are considered to be alcohol dependent.(1) Alcohol abuse and dependency is an economic burden to society that costs approximately $185 billion annually in the U.S.(6) Psychosocial support, such as counseling, is the traditional approach for treating alcohol dependence; however, experts in the field increasingly recommend and support a treatment approach that includes a combination of medication and psychosocial support.(7),(8)
