FDA Approves New Non-Opioid Pain Reliever
/By Pat Anson
Despite lackluster results in clinical trials, the U.S. Food and Drug Administration has approved a new non-opioid pain reliever for moderate to severe acute pain in adults.
Journavx (suzetrigine) is the first new medication for acute, short-term pain in over two decades. Unlike opioids, Journavx blocks pain signals in the peripheral nervous system, not in the brain, so it doesn’t have the same “liking” effects of opioids, which can lead to dependence or addiction.
The FDA calls its approval “an important public health milestone.”
"A new non-opioid analgesic therapeutic class for acute pain offers an opportunity to mitigate certain risks associated with using an opioid for pain and provides patients with another treatment option. This action and the agency's designations to expedite the drug's development and review underscore FDA's commitment to approving safe and effective alternatives to opioids for pain management," said Jacqueline Corrigan-Curay, MD, acting director of the FDA's Center for Drug Evaluation and Research.
Journavx was developed by Vertex Pharmaceuticals, which anticipates the drug to be used primarily for relieving post-operative pain or trauma. It is also being studied as a treatment for diabetic peripheral neuropathy and other types of chronic pain.
“This is an incredible day for patients and physicians alike who now have an approved non-opioid treatment that delivers effective acute pain relief and a favorable safety profile without addictive potential,” said Jessica Oswald, MD, a Vertex consultant and Associate Physician in Emergency Medicine and Pain Medicine in San Diego.
“I believe Journavx could redefine the management of pain and become a foundational treatment option for people with all types of moderate-to-severe acute pain, where options aside from opioids have been so desperately needed.”
The results from clinical trials suggest that Journavx is a mild pain reliever, at best.
In Phase 3 clinical studies of acute pain after minimally invasive surgeries, Journavx was no more effective than a low-dose combination of hydrocodone and acetaminophen, more commonly known as Vicodin.
In a recent Phase 2 study, Journavx was essentially no better than a placebo in relieving chronic back and hip pain caused by lumbosacral radiculopathy.
A recent report by ICER, an independent, non-profit research institute, said there were “uncertainties” about the efficacy and safety of Journavx.
“We have concerns about as-yet-unknown harms of suzetrigine as we would for any drug with a new mechanism of action; we are particularly concerned about whether there could be an increased risk for cardiac arrhythmias… and possible acute renal injury given a study in people with diabetes,” ICER said. “The above uncertainties inform our ratings that the evidence for suzetrigine for the treatment of acute pain in comparison with no systemic treatment, in comparison with opioid analgesics, and in comparison with NSAIDs are all promising but inconclusive.”
Journavx is being priced by Vertex at a wholesale cost for $15.50 per 50mg pill. When taken twice a day for acute pain, ICER estimates the cost at $420 for a one-week course. By comparison, a supply of 100 Vicodin tablets costs about $142.
The FDA’s approval of Journavx coincides with implementation of the NOPAIN Act, which makes non-opioid analgesics in outpatient surgical settings eligible for higher Medicare reimbursement rates.
The risk of a surgery patient misusing opioids or becoming addicted is less than one percent. One study found that patients who received no opioids during surgery were more likely to have post-operative pain and require opioids during recovery.
