TARRYTOWN, N.Y.--(BUSINESS WIRE)--Progenics Pharmaceuticals, Inc. (Nasdaq: PGNX - News), today announced the Therapeutic Goods Administration (TGA) division of the Australian Government has approved the registration of RELISTOR® (methylnaltrexone bromide 12mg/0.6ml solution for injection) for the treatment of opioid-induced constipation (OIC) in patients with advanced illness who are receiving palliative care when response to laxative therapy has not been sufficient.
“We are pleased that RELISTOR, an important new medicine to treat an unmet medical need, received registration approval in Australia, and is now available to patients with advanced illness receiving palliative care in another major region of the world,” said Paul J. Maddon, M.D., Ph.D., Chief Executive Officer, Chief Science Officer and Founder of Progenics Pharmaceuticals, Inc. “Approval in Australia expands global access to this novel product which has already received approval in Canada, the U.S., European Union member states, and Iceland, Norway, Liechtenstein and Venezuela. RELISTOR is the first approved therapy in a new class of drugs designed to relieve one of the significant side effects of opioids on the gastrointestinal tract without interfering with their ability to provide pain relief.”
Progenics, in collaboration with Wyeth, is developing RELISTOR for the treatment of opioid-induced side effects. Wyeth has worldwide rights to commercialize all forms of RELISTOR, except in Japan, where Progenics has granted Ono Pharmaceutical Co., Ltd. an exclusive license to the subcutaneous form of RELISTOR for development and commercialization in that country.
About RELISTOR
RELISTOR, a peripherally acting mu-opioid receptor antagonist, works by reducing the constipating side effects of opioids, such as morphine and codeine, without affecting their ability to relieve pain. Opioids provide analgesia - or relieve pain - by specifically interacting with mu-opioid receptors within the central nervous system (CNS), the area where pain is perceived - namely, the brain and spinal cord. However, opioids also interact with mu-opioid receptors found outside the CNS, such as those within the gastrointestinal tract, resulting in constipation that can be debilitating. RELISTOR selectively displaces opioids from the mu-opioid receptors outside the CNS, including those located in the gastrointestinal tract. Because of its chemical structure, RELISTOR has restricted access to the CNS.
About Subcutaneous RELISTOR
RELISTOR, administered via subcutaneous injection, is a peripherally acting mu-opioid receptor antagonist that decreases the constipating effects of opioid pain medications in the gastrointestinal tract without affecting their ability to relieve pain. Each year, more than 1.5 million Americans receive palliative care due to an advanced illness, such as incurable cancer and other end-stage diseases.
In April, the U.S. Food and Drug Administration approved RELISTOR subcutaneous injection for the treatment of opioid-induced constipation (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. RELISTOR was made available in the United States in June. In March, this form of RELISTOR was approved by Health Canada and was launched there in May. In July, RELISTOR (methylnaltrexone bromide) subcutaneous injection received marketing approval from the European Commission, and is now approved in the 27 member states of the E.U. as well as Iceland, Norway and Liechtenstein for the treatment of OIC in advanced illness patients who are receiving palliative care when response to usual laxative therapy has not been sufficient. Other applications in additional countries are also pending.
Important Safety Information for Subcutaneous RELISTOR
-- RELISTOR is contraindicated in patients with known or suspected mechanical gastrointestinal obstruction.
-- If severe or persistent diarrhea occurs during treatment, advise patients to discontinue therapy with RELISTOR and consult their physician.
-- Use of RELISTOR has not been studied in patients with peritoneal catheters.
-- The most common adverse reactions reported with RELISTOR in clinical trials were abdominal pain, flatulence, and nausea.
