Evoke Pharma Announces Conference Call to Review the Successful Results of Comparative Exposure Pharmacokinetic Study for Gimoti™

SOLANA BEACH, Calif., Oct. 27, 2017 (GLOBE NEWSWIRE) -- Evoke Pharma, Inc. (NASDAQ:EVOK), a specialty pharmaceutical company focused on treatments for gastrointestinal (GI) diseases, recently announced positive topline results from the Company's comparative exposure pharmacokinetic (PK) study for Gimoti, the Company's patented nasal delivery formulation of metoclopramide for the relief of symptoms associated with acute and recurrent diabetic gastroparesis. The trial demonstrated that more than one of the tested doses of Gimoti had similar systemic exposure to that of the referenced listed drug (RLD), Reglan Tablets. Based on these results, the Company will select a Gimoti dose and submit a 505(b)(2) New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) in the first quarter of 2018.

"The recently completed PK study was successful and achieved its objective of identifying a Gimoti dose for submission in the 505(b)(2) NDA. We look forward to the opportunity provide more clarity surrounding questions the company has received based on the recent data release," stated Dave Gonyer, President and CEO. "The results of this study were positive and an incredibly important milestone for the company and the development of Gimoti."

The conference call will focus on the topline results of the PK study and the Company's regulatory strategy for a 505(b)(2) NDA for Gimoti including:

• FDA discussions and feedback which allow for the selection of a Gimoti dose based on area under the plasma concentration curve (AUC) within the bioequivalence range of 80-125% of the RLD.
• Maximum observed plasma concentration (C_max) was anticipated to be lower than the RLD and results were in line with expectations. The Company discussed this with FDA during their review of the protocol and prior to study initiation.
• Regulations for innovator products such as Gimoti (21 CFR Part 320.23 Bioavailability and Bioequivalence Requirements) that allow for variations in rate of absorption (C_max).
• Two of three Gimoti doses achieved the required AUC range, even though only one was needed to meet the criteria.

The company plans to submit a 505(b)(2) NDA for Gimoti in the first quarter of 2018. The NDA will contain these PK data as well as safety and efficacy data from the additional five previously completed Gimoti studies in healthy volunteers and patients with diabetic gastroparesis.

Evoke will host a conference call and webcast at 9:00 am ET on Tuesday, October 31, 2017.

About Gimoti

Gimoti has been in development for over a decade to provide a non-oral, outpatient alternative to treat the symptoms of gastroparesis in patients. Non-oral treatment is optimal as gastroparesis, also known as gastric stasis, results in erratic absorption of oral medications. Metoclopramide, the active ingredient in Gimoti, has been approved as a tablet and an injection to treat gastroparesis in the US since 1980. Approximately 4 million prescriptions of oral metoclopramide are written per year in the US.

Evoke has conducted a number of clinical trials that will be submitted with data from the comparative exposure pharmacokinetic trial. These include a Phase 1 PK bioavailability study, a Phase 1 thorough ECG cardiac safety trial, a Phase 2b efficacy and safety trial, a Phase 3 efficacy and safety trial in women and a companion efficacy and safety trial in men.
