Evoke Pharma Presents Gimoti Efficacy and Safety Data from Phase 3 Trial as Late Breaker at Digestive Disease Week 2017

SOLANA BEACH, Calif., May 10, 2017 (GLOBE NEWSWIRE) -- Evoke Pharma, Inc. (NASDAQ:EVOK), a specialty pharmaceutical company focused on treatments for gastrointestinal (GI) diseases, today announced that data from its Phase 3 trial of Gimoti™, its patented nasal delivery of metoclopramide for the relief of symptoms associated with acute and recurrent diabetic gastroparesis in women, were presented at the Digestive Disease Week® (DDW) 2017 Meeting held in Chicago, Illinois.

The poster presentation entitled "Symptom Severity Influences Drug Efficacy in Women with Diabetic Gastroparesis: Results of a Phase 3 Study with Metoclopramide Nasal Spray" illustrated that patients with moderate to severe symptoms at study entry, which included 105 of the 205 patients (51%) enrolled in the study, responded clinically and statistically significantly better to Gimoti than placebo at multiple time points in the Intent-to-Treat (ITT) and Per Protocol populations. Focusing on the benefits in patients with moderate to severe symptoms is consistent with the U.S. Food and Drug Administration (FDA) guidance on the clinical evaluation of drugs for the treatment of gastroparesis issued in July 2015 (Gastroparesis: Clinical Evaluation of Drugs for Treatment, Draft Guidance).

In the Phase 3 trial, Gimoti was particularly effective in reducing nausea and upper abdominal pain, the most common and debilitating symptoms in patients with moderate to severe symptoms. This was similar to the benefits experienced by female patients in the Company's Phase 2b trial. Safety data from the Phase 3 trial were consistent with favorable results from previous Gimoti studies. In particular, there were no adverse events of special interest, such as the central nervous system (CNS) effects observed with oral and parenteral formulations of metoclopramide. Based on recent FDA discussions, these data are anticipated to be submitted as part of a new drug application (NDA) for Gimoti.

"As we prepare our 505(b)(2) NDA for Gimoti, including a comparative exposure pharmacokinetic (PK) study, acceptance of our Phase 3 data as a late breaker for poster presentation at DDW 2017 provided another opportunity for us to share the clinical importance of metoclopramide nasal spray for women suffering from the symptoms of moderate to severe diabetic gastroparesis," stated Marilyn R. Carlson, DMD, MD, Chief Medical Officer. "We are very pleased that DDW accepted this data for presentation as we believe it is among the most up-to‑the-minute and novel GI developments that will impact research and the care of patients."

The Phase 3 trial was a U.S. multicenter, randomized, double-blind, placebo-controlled, parallel‑group study of the efficacy and safety of Gimoti compared to placebo in adult female subjects with symptomatic diabetic gastroparesis and delayed gastric emptying. Eligible patients were randomized 1:1 between Gimoti or placebo administered as a single nasal spray four times daily; 30 minutes before meals and at bedtime for a total of four weeks. The primary endpoint was the change in the total symptom score from baseline to week four. The trial data was not statistically significant in the ITT group (N=205, p=0.881).

The authors of the presentation were Richard W. McCallum, MD, Texas Tech University Health Sciences Center, El Paso, Texas; Ronnie Fass, MD, Case Western Reserve University, Cleveland, Ohio; Bal R. Bhandari, MD, Delta Research Partners, Monroe, Louisiana; Marilyn R. Carlson, DMD, MD and Wayne M. Alves, PhD, Evoke Pharma, Inc., Solana Beach, California.
