Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that the U.S. Food and Drug Administration (FDA) has approved JOURNAVX™ (suzetrigine), an oral, non-opioid, highly selective NaV1.8 pain signal inhibitor for the treatment of adults with moderate-to-severe acute pain.

“Today’s approval is a historic milestone for the 80 million people in America who are prescribed a medicine for moderate-to-severe acute pain each year,” said Reshma Kewalramani, M.D., Chief Executive Officer and President of Vertex. “With the approval of JOURNAVX, a non-opioid, pain signal inhibitor and the first new class of pain medicine approved in more than 20 years, we have the opportunity to change the paradigm of acute pain management and establish a new standard of care.”

“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, M.D., M.P.H., Associate Physician in Emergency Medicine and Pain Medicine in San Diego and Vertex Acute Pain Steering Committee Member. “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.”

As part of Vertex’s ongoing commitment to patients, the company has established patient support programs to help ensure that qualified patients can access JOURNAVX. For more information visit JOURNAVX.com.

About Acute Pain

Acute pain is a serious and potentially disabling condition often caused by surgery, accident or injury. Over 80 million Americans are prescribed medicine to treat their moderate-to-severe acute pain every year. Of these, about 40 million are prescribed an opioid. Nearly 10% of acute pain patients treated initially with an opioid will go on to have prolonged opioid use, and about 85,000 patients will develop opioid use disorder annually. Poorly controlled acute pain can lead to reduced quality of life, development of chronic pain, and increased burden on the health care system and society.

About JOURNAVX™ (suzetrigine)

JOURNAVX (suzetrigine) is a first-in-class, oral, non-opioid, highly selective pain signal inhibitor that is selective for NaV1.8 relative to other NaV channels. NaV1.8 is a voltage-gated sodium channel that is selectively expressed in peripheral pain-sensing neurons (nociceptors), where its role is to transmit pain signals (action potentials). Because JOURNAVX blocks pain signals only found in the periphery, not in the brain, JOURNAVX provides effective relief of pain without the limitations of currently available therapies, including the addictive potential of opioids.

The U.S. Food and Drug Administration approved twice-daily JOURNAVX for the treatment of adults with moderate-to-severe acute pain. Vertex has established a wholesale acquisition cost for JOURNAVX in the United States of $15.50 per 50mg pill.

Vertex is also evaluating suzetrigine in peripheral neuropathic pain (PNP). The company’s Phase 3 pivotal program for suzetrigine in patients with painful diabetic peripheral neuropathy is ongoing, and Vertex plans to advance its pivotal program evaluating suzetrigine in patients with painful lumbosacral radiculopathy pending discussions with regulators.
