Retrieved 14 November 2022. Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that it has begun a Phase 2 proof-of-concept (POC) study in acute pain following bunionectomy surgery with the selective NaV1.8 inhibitor VX-548 and that it expects to commence a second Phase 2 study in acute pain following abdominoplasty surgery in the coming weeks.

Archived from the original on 19 May 2022. Retrieved 14 November 2022. "There is an enormous need for novel non-opioid analgesics with no abuse liability," and Vertex's results are an "important advance," said Dr. Clifford J. Woolf, director of the F.M. Kirby Neurobiology Center and Boston Children's Hospital. It will be important for Vertex to determine whether the drug also works for patients with chronic pain, such as diabetic neuropathy and low back pain, "where the clinical need is highest," he added.
