Janssen’s NUCYNTA ER tablets more effective in providing pain management in adults with DPN

Janssen Pharmaceuticals, Inc. today announced the results of an investigational Phase 3 study suggesting NUCYNTA® ER (tapentadol) extended-release tablets were significantly more effective than placebo in providing pain management among adults with chronic moderate to severe, painful diabetic peripheral neuropathy (DPN). Results of the study were presented at the 31st Annual Scientific Meeting of the American Pain Society being held May 16-19 in Honolulu, Hawaii.

Diabetes affects nearly 26 million people in the United States– and its prevalence is expected to grow significantly during the coming decades. Over time, people with diabetes can develop a type of nerve damage called neuropathy. Approximately 60 to 70 percent of people with diabetes have some form of neuropathy. The most common type is diabetic peripheral neuropathy, which causes pain or loss of feeling in the toes, feet, legs, hands, and arms.

The study found, among patients who had at least a one-point reduction in pain intensity during three weeks of treatment with tapentadol ER, those who continued on an optimized dose of tapentadol ER (100-250 mg twice daily) for an additional 12 weeks experienced significantly better pain control compared to those who switched to placebo. Treatment-emergent adverse events reported in 10 percent or more of tapentadol ER-treated patients during the double-blind maintenance period included nausea (21.1 percent) and vomiting (12.7 percent).

"Painful DPN is a common and burdensome complication of diabetes, and controlling pain in people with DPN can be challenging," said Aaron I. Vinik, M.D., Ph.D., FCP, MACP, Director of Research and Neuroendocrine Unit at Strelitz Diabetes Center for Endocrine and Metabolic Disorders at Eastern Virginia Medical School, and lead investigator of the study. "These data suggest tapentadol ER provides a significant reduction in chronic pain in adult patients with DPN."

The findings of this study are consistent with those of another Janssen-sponsored study published early last year, which found tapentadol ER to be effective versus placebo for relieving moderate to severe chronic pain associated with diabetic peripheral neuropathy.

"We are pleased the Phase 3 data presented today showed tapentadol ER was effective at providing pain management for patients with chronic, moderate to severe pain associated with DPN," said Christine Rauschkolb, M.D., Ph.D., Vice President and Head of Integrated Operations, Janssen Research & Development, LLC and one of the study's authors. "Janssen has a long history of helping physicians provide responsible treatment for patients to relieve their acute and chronic pain. We are committed to developing new pain management options for the millions of Americans who have painful DPN."
