Shionogi & Co., Ltd. Announces That Naldemedine Meets Primary Endpoint In A Phase 3 Study For The Treatment Of Opioid-Induced Constipation
FLORHAM PARK, N.J., March 30, 2015 /PRNewswire/ -- Naldemedine, an investigational peripherally acting mu-opioid receptor antagonist (PAMORA) under development by Shionogi & Co., Ltd., met its primary and secondary endpoints in a phase III study (COMPOSE I) for the treatment of opioid-induced constipation (OIC) in adult patients with chronic non-cancer pain receiving opioid therapy. Study results showed that naldemedine (0.2 mg tablet given once daily) statistically significantly improved the frequency of spontaneous bowel movement (SBM) compared with placebo over 12 weeks. Naldemedine was generally well-tolerated with the most commonly reported side effects being gastrointestinal disorders. This is the first phase III data generated from the COMPOSE program.
"OIC is one of the most common side effects of chronic opioid therapy, and can negatively impact a person's quality of life, including limitations in daily activities, impairments in psychological well-being, and decreases in work productivity," Juan Camilo Arjona Ferreira, MD, Senior Vice President Clinical Development. "We are encouraged by the results of this study, and hope to deliver a new therapeutic solution to the millions of patients suffering from this debilitating condition."
About COMPOSE Program
The COMPOSE program is a global comprehensive development program comprised of 7 clinical studies being conducted in patients with OIC with cancer or chronic non-cancer pain.
COMPOSE I is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study. The study was designed to evaluate the efficacy and safety of naldemedine therapy, versus placebo, in 547 patients receiving chronic opioid therapy, who experience OIC accompanied by chronic non-cancer pain.
About Opioid Induced Constipation (OIC)
OIC is defined as follows: "A change when initiating opioid therapy from baseline bowel habits that is characterized by any of the following: reduced bowel movement frequency, development or worsening of straining to pass bowel movements, a sense of incomplete rectal evacuation, or harder stool consistency."1 It is estimated that 40-50% (approximately 30M globally) of chronic opioid patients experience opioid-induced constipation, with fewer than half reporting satisfactory results with laxatives.2 Managing OIC and its clinical consequences places a significant financial burden on the healthcare system and the patient.
