The U.S. Food and Drug Administration approved Lucemyra for the mitigation of withdrawal symptoms to facilitate abrupt discontinuation of opioids in adults.

While Lucemyra may lessen the severity of withdrawal symptoms, it may not completely prevent them and is only approved for treatment for up to 14 days. Lucemyra is not a treatment for opioid use disorder (OUD), but can be used as part of a broader, long-term treatment plan for managing OUD.

Opioid withdrawal includes symptoms – such as anxiety, agitation, sleep problems, muscle aches, runny nose, sweating, nausea, vomiting, diarrhea and drug craving – that occur after stopping or reducing the use of opioids in anyone with physical dependence on opioids.

In patients using opioid analgesics appropriately as prescribed, opioid withdrawal is typically managed by slow taper of the medication, which is intended to avoid or lessen the effects of withdrawal while allowing the body to adapt to not having the opioid.

In patients with OUD, withdrawal is typically managed by substitution of another opioid medicine, followed by gradual reduction or transition to maintenance therapy with FDA-approved medication-assisted treatment drugs such as methadone, buprenorphine or naltrexone; or by various medications aimed at specific symptoms, such as over-the-counter remedies for upset stomach or aches and pains.

“Today’s approval represents the first FDA-approved non-opioid treatment for the management of opioid withdrawal symptoms and provides a new option that allows providers to work with patients to select the treatment best suited to an individual’s needs,” said Sharon Hertz, M.D., director of the Division of Anesthesia, Analgesia and Addiction Products in the FDA’s Center for Drug Evaluation and Research.

The safety and efficacy of Lucemyra was supported by two randomized, double-blind, placebo-controlled clinical trials of 866 adults meeting Diagnostic and Statistical Manual-IV criteria for opioid dependence who were physically dependent on opioids and undergoing abrupt opioid discontinuation.

The FDA is requiring 15 postmarketing studies, including both animal and human studies. Additional animal safety studies will be required to support longer-term use (such as during a gradual opioid taper in pain patients discontinuing opioid analgesics) and use in children.

The FDA granted this application Priority Review and Fast Track designations, and an independent FDA advisory committee supported the approval of Lucemyra at a meeting held March.
