Indivior drug to fight opioid addiction by US panel

WASHINGTON, DC: Indivior’s experimental drug to help fight America’s growing opioid addiction crisis has been recommended for approval by a US advisory panel, boosting its sales prospects as competitors threaten revenues from an older product. Shares in the London-listed company, which specializes in addiction treatment, were 11 percent higher by 0855 GMT on Wednesday on the overnight news, extending gains this week.

The advisory committee to the US Food and Drug Administration (FDA) voted 18-1 that Indivior’s injectable drug, known as RBP-6000, could benefit addicts and the lower of two doses studied had an acceptable safety profile. The FDA, which is due to make a decision on the medicine by Nov. 30, typically follows the recommendations of its advisory panels. The endorsement comes less than a week after FDA Commissioner Scott Gottlieb announced the agency’s plans to encourage widespread use among opioid addicts of less harmful opioids such as methadone and buprenorphine, the active ingredient in RBP-6000.

“I think this is a really promising alternative to what’s out there and will be attractive to a lot of patients,” said Laurel Habel, a panelist and researcher at Kaiser Permanente in Oakland, California. The United States is battling an opioid abuse epidemic that in 2015 killed 33,000 people. President Donald Trump recently declared the problem a national public health emergency. Indivior studied two dosing regimens. In one, 300 milligrams were given once a month for six months. In the other, two doses of 300 milligrams were followed by four doses of 100 milligrams. There was little difference in effectiveness between the two doses and the higher dose caused more side effects. — Reuters
