SOLANA BEACH Calif., March 04, 2019 (GLOBE NEWSWIRE) -- Evoke Pharma, Inc. (EVOK), today announced the receipt of a multi-disciplinary review (DR) letter from the U.S. Food and Drug Administration (FDA) in association with the Gimoti 505(b)(2) New Drug Application (NDA). A DR letter is used by the FDA to convey preliminary thoughts on deficiencies identified during the initial stage of NDA review.
The letter described concerns in three sections of the NDA: Chemistry (combination product quality control and reproducibility specific to the commercially available sprayer device used with Gimoti); Clinical (lack of adequate information to support sex-based efficacy differences); and Clinical Pharmacology (maximum concentration (Cmax) not within the parameters for bioequivalence for abbreviated NDAs). Although a DR letter reflects preliminary comments that are subject to change and does not reflect a final FDA decision on the NDA, approval of Gimoti by the PDUFA date of April 1, 2019 is uncertain given the letter.
The Company plans to respond to the deficiencies raised in the DR letter to allow time for potential FDA review prior to the PDUFA date.
“We were disappointed by this FDA notification and are in the process of evaluating and addressing FDA’s comments. We remain focused on seeking approval for Gimoti to provide patients with an effective treatment that bypasses the stomach where oral medications are known to be erratically absorbed,” said Dave Gonyer, CEO. “Predictably delivered therapeutic options for patients that suffer from gastroparesis remains of high interest to the Company and an important need for physicians and patients that suffer from gastroparesis.”
Gastroparesis is a debilitating, episodic condition that disproportionately affects adult women and is characterized by slow or delayed gastric emptying of the stomach’s contents after meals, often resulting in flares of symptoms that include nausea, vomiting, abdominal pain and bloating. Vomiting and gastric emptying delays can cause unpredictable absorption of food and oral medications, which complicate glucose control and can lead to dehydration and malnutrition. These clinical manifestations of gastroparesis also potentially render existing oral drug treatment options ineffective. If approved, Gimoti would be the first non-oral drug treatment for symptoms associated with acute and recurrent diabetic gastroparesis in adult women and would represent the first significant advancement in the treatment of gastroparesis in 40 years.

Diabetic gastroparesis is a GI disorder affecting millions of patients worldwide, in which the stomach takes too long to empty its contents resulting in serious digestive system symptoms. The gastric delay caused by gastroparesis can compromise absorption of orally administered medications. Metoclopramide is currently available only in oral and injectable formulations and is the only drug currently approved in the United States to treat gastroparesis.
