Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) and Progenics Pharmaceuticals (NASDAQ:PGNX) today announced that the Food and Drug Administration (FDA or Agency) has informed Salix that the supplemental New Drug Application (sNDA) for RELISTOR ® (methylnaltrexone bromide) Subcutaneous Injection, 20 mg/ml, for the treatment of opioid-induced constipation (OIC) in patients taking opioids for chronic non-cancer pain has been assigned a user fee goal date of September 29, 2014. On July 10, 2014 the FDA Office of Drug Evaluation III responded to the Company’s formal appeal filed in response to the Complete Response Letter (CRL) of July 27, 2012 to the supplemental NDA (sNDA) for RELISTOR. The Agency’s letter stated that, “Salix’s request that FDA approve the supplemental NDA for RELISTOR subcutaneous injection for the treatment of opioid-induced constipation in patients with chronic non-cancer pain based on the submitted data is granted.” In regard to the RELISTOR sNDA the Agency directed Salix to work with and submit certain information to the Division of Gastroenterology and Inborn Errors Products (DGIEP). On July 29, 2014 the FDA accepted Salix’s resubmission. On August 8, 2014 the FDA communicated to Salix that the Company’s resubmission is a complete, class 1 response to the FDA’s action letter and assigned the user fee goal date. “The approval and availability of RELISTOR for this expanded use will be an important and welcomed advancement for treating the underlying cause of OIC experienced by many patients taking opioids for chronic non-cancer pain,” stated Bill Forbes, Executive Vice President, Medical, Research and Development and Chief Development Officer, Salix. “Frequently, opioid analgesics are prescribed to manage pain in patients suffering from chronic conditions. Unfortunately, the use of an opioid can result in debilitating constipation for a significant number of these patients. RELISTOR is a peripherally acting mu-opioid receptor antagonist (PAMORA) designed to counteract the constipating effects of opioid pain medications without affecting their ability to relieve pain.”
About Opioids, Constipation and RELISTOR (methylnaltrexone bromide)Opioid analgesics are frequently prescribed for patients with chronic pain, including patients with advanced illness. An estimated 27 million patients in the US are on opioids for chronic pain. Constipation is one of the most common and distressing side effects in patients receiving chronic opioid therapy. Approximately 40% of chronic pain patients, or nearly 11 million patients, on opioid therapy will experience OIC. RELISTOR is the first approved medication that specifically targets the underlying cause of OIC. RELISTOR is a Peripherally Acting Mu Opioid Receptor Antagonist (PAMORA) specifically designed to block the constipating effects of opioids in the gastrointestinal tract. The unique molecular structure of RELISTOR restricts it from crossing the blood brain barrier and interfering with the analgesic effect of opioids. In clinical trials, approximately 50% of patients experienced relief of OIC in as little as 4 hours. RELISTOR is the only PAMORA currently approved by the FDA for the treatment of OIC in patients with advanced illness receiving palliative care when the response to laxatives has been insufficient. RELISTOR Subcutaneous Injection was approved in the United States in 2008 for the treatment of OIC in patients with advanced illness who are receiving palliative care, when response to laxative therapy has not been sufficient. The use of RELISTOR beyond four months has not been studied in the advanced illness population. The drug is also approved for use in over 50 countries worldwide, including the European Union, Canada, and Australia. In the 28 member countries of the E.U., as well as Iceland, Norway and Liechtenstein, RELISTOR is approved for the treatment of OIC in advanced illness patients who are receiving palliative care when response to usual laxative therapy has not been sufficient. In Canada, the drug is approved for the treatment of OIC in patients with advanced illness, receiving palliative care. When response to laxatives has been insufficient, RELISTOR should be used as an adjunct therapy to induce a prompt bowel movement. Applications in additional countries are pending. RELISTOR is under license to Salix Pharmaceuticals, Inc. from Progenics Pharmaceuticals, Inc.

Cases of gastrointestinal (GI) perforation have been reported in adult patients with opioid-induced constipation and advanced illness with conditions that may be associated with localized or diffuse reduction of structural integrity in the wall of the GI tract (i.e., cancer, peptic ulcer, Ogilvie's syndrome). Perforations have involved varying regions of the GI tract (e.g., stomach, duodenum, or colon). Use RELISTOR with caution in patients with known or suspected lesions of the GI tract. Advise patients to discontinue therapy with RELISTOR and promptly notify their physician if they develop severe, persistent, or worsening abdominal symptoms. If severe or persistent diarrhea occurs during treatment, advise patients to discontinue therapy with RELISTOR and consult their physician. Use of RELISTOR beyond four months has not been studied. Safety and efficacy of RELISTOR have not been established in pediatric patients. The most common adverse reactions reported with RELISTOR compared with placebo in clinical trials were abdominal pain (28.5%), flatulence (13.3%), nausea (11.5%), dizziness (7.3%), diarrhea (5.5%), and hyperhidrosis (6.7%).
