Valeant Pharmaceuticals International, Inc. and Progenics Pharmaceuticals, Inc. announced that the FDA has approved RELISTOR® (methylnaltrexone bromide) tablets for the treatment of opioid-induced constipation (OIC) in adults with chronic non-cancer pain.

Valeant expects to commence sales of RELISTOR Tablets in the U.S. in the third quarter of 2016.

“Opioid-induced constipation represents a long-lasting and potentially debilitating side effect of opioid therapy for millions of patients suffering from chronic pain,” commented Joseph C. Papa, Chief Executive Officer of Valeant. “We believe Oral RELISTOR represents a new alternative treatment for OIC, and we look forward to introducing the more convenient oral formulation as soon as practicable.”

“We are delighted that this milestone for RELISTOR has been achieved, and that patients suffering from OIC will have this new treatment option,” said Mark Baker, Chief Executive Officer of Progenics. “We expect the market to be receptive to a more convenient oral tablet formulation of RELISTOR’s well-established subcutaneous preparation. We would like to thank, in particular, Dr. Tage Ramakrishna and Dr. Robert Israel of Valeant for their work over many years in the clinical development of RELISTOR.”

“RELISTOR has a unique mechanism of action that binds to mu-opioid receptors without impacting the opioid-mediated analgesic effects on the central nervous system,” said Richard L. Rauck, MD, Medical Director, Center for Clinical Research, President, Carolinas Pain Institute, President of the Sceptor Pain Foundation of which he is a founding member, and Immediate Past President of the World Institute of Pain. “This represents a true breakthrough in the treatment of OIC, and addresses a large and growing need in the field of pain management.”

Today, the FDA approved RELISTOR Tablets (450 mg once daily) for the treatment of OIC in adults with chronic non-cancer pain.  Previously, RELISTOR Subcutaneous Injection (12 mg and 8 mg) was approved in 2008 for the treatment of OIC in adults with advanced illness who are receiving palliative care and in 2014 for the treatment of OIC in adults with chronic non-cancer pain.
