Vertex Stock Plunges Over Pain Drug's Disappointing Study Results -- WSJ

Dow Jones12-20

By Joseph Walker

Shares of Vertex Pharmaceuticals sank Thursday, following disappointing study results for a non-opioid painkiller.

Vertex said the drug significantly reduced pain in people with a common form of lower back pain in a Phase 2 study. But patients who got a placebo saw similar improvements- raising concerns about the drug's future and if it will work in a new, larger study needed for approval.

It was a blow to hopes the drug, suzetrigine, could become a big seller.

"We believe the results overall raise major questions about whether the drug can ultimately succeed" in treating a form of back pain that represents about 40% of all chronic pain cases, said RBC Capital Markets analyst Brian Abrahams in a note to clients.

Shares in Vertex recently stood about 12% lower.

Vertex said the Phase 2 study wasn't designed to compare the patients who received its drug with those who received a placebo. Vertex said it will talk with the Food and Drug Administration about how to best design a Phase 3 study in lower back pain.

Vertex's suzetrigine is pending approval to treat acute pain, a different use than the subject of the newly released study, with a decision by the FDA expected by Jan. 30.
