Alkermes 2011 Milestones
During the year, Alkermes expects:
Program Highlights to be Presented at JPMorgan Conference
- Expansion of the ALKS 33 clinical program into TRD: Alkermes will announce that ALKS 33, in combination with buprenorphine, is being studied for TRD. TRD, which is also known as refractory depression, refers to depressive episodes that are not adequately controlled by standard antidepressant therapy. Depression is a serious and chronic disease that affects more than 20 million American adults each year1 and finding the right treatment can be difficult for many patients. Approximately half of depressed patients have an inadequate response to monotherapy2 and as many as 20% have chronic depression despite multiple interventions.3 ALKS 33 and buprenorphine have established activity at the Mu receptor, although buprenorphine is a partial agonist while ALKS 33 is an antagonist. The net effect of this combination may attenuate buprenorphine’s Mu agonist effects. Blockade activity from the combination of ALKS 33 and buprenorphine at Kappa opioid receptors may affect neurochemical changes associated with depression. Preclinical research has demonstrated that Kappa blockade has antidepressant effects in behavioral models of depression. The company plans to file an Investigational new Drug application (IND) in mid-calendar year 2011 and initiate a phase 1/2 trial by the end of calendar year 2011.The expansion of the ALKS 33 clinical program into TRD follows the recent announcement of phase 2 data for ALKS 33 for the treatment of alcohol dependence. this phase 2 study was designed to assess the safety, tolerability, pharmacokinetics and efficacy of daily oral administration of three different dose levels of ALKS 33 compared to placebo in approximately 400 alcohol dependent patients. The phase 2 study showed that ALKS 33 was generally well tolerated and characterized by its potential for daily dosing, non-hepatic metabolism, extended pharmacologic benefit in the event of missed doses and pharmacologic activity in reducing heavy drinking behavior. ALKS 33 is also in clinical development for the treatment of binge eating disorder and as a combination therapy with buprenorphine for the treatment of cocaine addiction.
- Positive phase 4 data for VIVITROL in the treatment of healthcare professionals with opioid dependence: Alkermes will present interim data from an ongoing, multicenter, open-label, two-year, phase 4 study of VIVITROL. this study is designed to evaluate the safety and efficacy of VIVITROL in the treatment of 38 healthcare professionals with a history of opioid dependence who are enrolled in an extended outpatient treatment program that includes psychosocial support, such as counseling. At the time of the interim analysis, of the 38 patients who initiated VIVITROL treatment, approximately 70% of subjects persisted with VIVITROL treatment for at least six months, all of whom had opioid-free screens for the full six-month period.according to the 2009 U.S. National Survey on Drug use and Health, an estimated 1.6 million people aged 18 or older were dependent on pain relievers or heroin.4 Physicians display higher rates of prescription drug abuse and dependence than the general population, including misuse of prescription opioids.5 Physician impairment is a major public health issue, as it affects not only these individuals but also their patients, colleagues and families.

About VIVITROL
VIVITROL (naltrexone for extended-release injectable suspension) 380 mg/vial is the first and only once-monthly, extended-release injectable medication for the treatment of alcohol dependence and opioid dependence. 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. The VIVITROL clinical development program was funded in part with a Small Business Innovation Research Program grant from the National Institute of Drug Abuse (NIDA). For a copy of the VIVITROL full prescribing information, please visit vivitrol.com or call 1-800-VIVITROL (1-800-848-4876). Please see below for important safety information, including boxed warning.
VIVITROL IMPORTANT SAFETY INFORMATION
VIVITROL is contraindicated in patients with acute hepatitis or liver failure, patients receiving opioid analgesics, patients with current physiologic opioid dependence, patients in acute opioid withdrawal, any individual who has failed the naloxone challenge test or has a positive urine screen for opioids, and in patients who have previously exhibited hypersensitivity to naltrexone, polylactide-co-glycolide (PLG), carboxymethylcellulose or any other components of the diluent.
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 administered as an intramuscular (IM) gluteal injection. Inadvertent subcutaneous injection of VIVITROL may increase the likelihood of severe injection site reactions. VIVITROL must be injected using one of the customized needles provided in the carton. Because needle length may not be adequate due to body habitus, each patient should be assessed prior to each injection to assure that needle length is adequate for IM administration. VIVITROL injections may be followed by pain, tenderness, induration, swelling, erythema, bruising or pruritus; however, in some cases injection site reactions may be very severe. Injection site reactions not improving may require prompt medical attention, including in some cases surgical intervention.
Consider the diagnosis of eosinophilic pneumonia if patients develop progressive dyspnea and hypoxemia. Patients should be warned of the risk of hypersensitivity reactions, including anaphylaxis. Opioid-dependent patients including those being treated for alcohol dependence, must be opioid-free for a minimum of 7-10 days before VIVITROL treatment. Attempts to overcome opioid blockade due to VIVITROL may result in a fatal overdose. After opioid detoxification, patients are likely to have reduced tolerance to opioids. use of lower doses of opioids after VIVITROL is discontinued, at the end of a dosing interval or after missing a dose could result in life threatening opioid intoxication. Alcohol- and opioid-dependent patients, including those taking VIVITROL, should be monitored for the development of depression or suicidal thoughts. as with any IM injection, VIVITROL should be administered with caution to patients with thrombocytopenia or any coagulation disorder. In an emergency situation in patients receiving VIVITROL, suggestions for pain management include regional analgesia or use of non-opioid analgesics. Patients requiring reversal of the VIVITROL blockade for pain management should be monitored by appropriately trained personnel in a setting equipped for cardiopulmonary resuscitation. Caution is recommended in administering VIVITROL to patients with moderate to severe renal impairment.
The adverse events seen most frequently in association with VIVITROL therapy for alcohol dependence include nausea, vomiting, injection site reactions (including induration, pruritus, nodules and swelling), muscle cramps, dizziness or syncope, somnolence or sedation, anorexia, decreased appetite or other appetite disorders. The adverse events seen most frequently in association with VIVITROL in opioid-dependent patients include hepatic enzyme abnormalities, injection site pain, nasopharyngitis, insomnia, and toothache.
