Press Release

Shionogi : Receives Positive Opinion for Rizmoic in Latest Announcement from the Committee for Medicinal Products for Human Use

Shionogi & Co.
Posted on: 24 Dec 18

OSAKA - Shionogi & Co., Ltd. (hereafter 'Shionogi'), a research-driven pharmaceutical company, announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending the granting of a marketing authorisation for naldemedine for the treatment of opioid induced constipation (OIC) in adult patients who have previously been treated with a laxative.

The European Commission will issue a decision in due course for Rizmoic (naldemedine), taking into account the recommendation from the CHMP.

Welcoming the announcement, Dr. John Keller, Chief Executive Officer of Shionogi Ltd, said: 'This CHMP positive opinion is important as it adds another therapeutic option for the treatment of opioid induced constipation (OIC) in patients in Europe living with cancer or chronic non-cancer pain.'

Opioid-induced constipation (OIC) is a prevalent and distressing side effect of opioid therapy that does not reliably respond to treatment with conventional laxatives.1

Naldemedine, which has already been approved for routine use in the US and Japan, is an antagonist of opioid binding at the mu-, delta-, and kappa-opioid receptors. Naldemedine is a derivative of naltrexone to which a side chain has been added that increases the molecular weight and the polar surface area, thereby reducing its ability to cross the blood-brain barrier (BBB); the CNS penetration of naldemedine is expected to be negligible at the recommended dose. Additionally, naldemedine is a substrate of the P-glycoprotein (P-gp) efflux transporter, which may also be involved in reducing naldemedine penetration into the CNS. Based on this, naldemedine is expected to exert its anti-constipating effects on opioids without reversing their CNS-mediated analgesic effects.

About Opioid-induced Constipation

Constipation is one of the most commonly reported side effects associated with opioid treatment, including among patients with chronic non-cancer pain and patients with cancer.7 OIC is a result of increased fluid absorption and reduced GI motility due to mu opioid receptor binding in the GI tract. OIC is defined as a change in bowel habits that is characterized by any of the following after initiating opioid therapy: reduced bowel movement frequency, development or worsening of straining to pass bowel movements, a sense of incomplete rectal evacuation, or harder stool consistency.8 In patients receiving opioid therapy for chronic non-cancer pain, the prevalence of OIC ranges from approximately 40-60 percent.1
