(EVOK) Positive Study Results For Metoclopramide Nasal Spray

SAN DIEGO, Jan. 22, 2014  — Evoke Pharma, Inc. (Nasdaq:EVOK), a specialty pharmaceutical company focused on treatments for gastrointestinal (GI) diseases, today announced the publication of a study that found intranasal delivery of metoclopramide to be more effective in managing symptoms of diabetic gastroparesis compared to the marketed oral tablet formulation of metoclopramide.

The Phase 2b study, which was published online ahead-of-print for an upcoming issue of Neurogastroenterology & Motility, enrolled 89 patients from six study sites throughout the United States. The multicenter, randomized, open-label, parallel design study was the first to compare the efficacy and safety of metoclopramide nasal spray to oral tablets in diabetic patients with symptoms of gastroparesis when dosed four times a day for 6 weeks.

Marilyn Carlson, D.M.D., M.D., RAC, Chief Medical Officer of Evoke, said, “It is intuitive that a nasal spray will have more reliable absorption than a tablet in patients with delayed gastric emptying. These data from symptomatic diabetic gastroparesis patients confirm that metoclopramide nasal spray is well-tolerated and can offer better symptom relief than a tablet in this population.”

“We believe the results from our Phase 2b clinical trial validate our novel intranasal delivery system of metoclopramide (EVK-001) which will be evaluated soon in our upcoming Phase 3 clinical trial,” said Dave Gonyer, R.Ph., President and Chief Executive Officer of Evoke. “There haven’t been any new drugs for the management of symptoms associated with gastroparesis approved by the FDA since 1980, and there are very few drugs in clinical development for this debilitating diabetic complication.”
