Chesterfield-based Indivior targets spot at top of addiction treatment industry,
carries lingering legal troubles
By Sean Jones, Business Reporter, Richmond Times-Dispatch, Richmond, VA, December 19, 2022 – A Richmond-area pharmaceutical company is targeting a place at the top of the addiction treatment industry.
Indivior PLC made a name for itself in the space by commercializing Suboxone, one of the most widely used drugs in the treatment of opioid use disorder.
The company could become more influential in the industry after the announcement of a planned merger with the developer of Narcan, a widely used drug to recover from opioid overdoses. The move could see the company create more rescue medications and treatment drugs for opioid use disorder and other addictions.
Chesterfield County-based Indivior heads into that new future while carrying the burden of significant litigation. It is currently battling a class action suit where 41 states, including Virginia, have accused it of a scheme to keep generics makers from entering the addictions market.
The company stopped U.S. distributions of the Suboxone tablet in 2013 and later stopped marketing its Suboxone film. It then moved to a new product in 2017, Sublocade, which is now one of the leading treatments for opioid addiction.
Indivior CEO Mark Crossley said the drug was “paradigm shifting” in its strength as a treatment for opioid dependency.
The once-monthly buprenorphine injectable works by blocking the reward sensation from opioids. Patients also only need to take the medication once a month, rather than daily.
“It takes patient choices down from 365 choices a year, down to 12 choices a year,” Crossley said. “It occupies receptors in the brain so if someone were to have a moment of weakness, and use an opioid of abuse, it can’t get to the receptor because the buprenorphine is occupying it.”
Having been first approved by the Food and Drug Administration in 2017, Sublocade has become the company’s biggest current asset, accounting for $244 million of its total $791 million in 2021 revenue. Public documents show that Indivior expects those sales to increase to between $360 million and $400 million by the end of 2022.
That portfolio is on the cusp of growing even larger, beyond just drugs for the treatment of opioids, but the treatment of other substance use disorders. The company plans to sell recovery drugs for people going through a drug overdose.
Indivior recently announced its intention to acquire Opiant Pharmaceuticals Inc. for a reported $145 million, pending regulatory and shareholder approval. Opiant is best known for creating Narcan, a widely used reversal agent for opioid overdoses. The nasal spray has become a go-to for first responders during the continued opioid epidemic.
Opiant is in the late stage of researching a new rescue medication that’s expected to push the boundary of overdose recovery drugs even further. Indivior said the product, currently named OPNT003, is a stronger version of Narcan. The nalmefene-based medicine occupies the brain’s receptors far longer than the naloxone-based Narcan.
