Evoke Pharma Receives Complete Response Letter and Recommendations to Address Deficiencies from FDA for Gimoti™ NDA

SOLANA BEACH, Calif., April 02, 2019 (GLOBE NEWSWIRE) -- Evoke Pharma, Inc. (EVOK), a specialty pharmaceutical company focused on treatments for gastrointestinal (GI) diseases, today announced that it has received a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) for its 505(b)(2) New Drug Application (NDA) for Gimoti for the relief of symptoms associated with acute and recurrent diabetic gastroparesis.

The CRL, which cites fewer issues than the recent multidisciplinary review letter, states that FDA has determined it cannot approve the NDA in its present form and provides recommendations to address the two remaining approvability issues in an NDA resubmission. The issues are related to clinical pharmacology and product quality/device quality. The Agency did not request any new clinical data and did not raise any safety concerns.

The clinical pharmacology issue was specific to a low Cmax in subjects representing less than 5% of the total administered Gimoti doses in the pivotal pharmacokinetic (PK) study. The Agency stated the overall lower mean Cmax was driven by the data from these few subjects. Without the aberrant doses, the Company’s analysis shows the data met the bioequivalence criteria for both men and women. The Agency recommended a root cause analysis to determine the origin of the PK variability and mitigation strategies to address the issue. Additionally, FDA requested data from previously planned registration batches of commercial product to be manufactured by the Company. These data were requested to provide additional support for the proposed acceptance criteria for droplet size distribution after actuation of the sprayer device.  

“We believe that the issues cited in the CRL, which were related to concerns over reproducible dose delivery, can be addressed. We look forward to meeting with FDA to gain a full understanding of the Agency’s requirements for approval and remain committed to bringing our novel nasal formulation of metoclopramide to patients,” said Dave Gonyer, President and CEO.

About 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.

About Evoke Pharma, Inc.

Evoke is a specialty pharmaceutical company focused primarily on the development of drugs to treat Gastrointestinal (GI) disorders and diseases. The Company is developing Gimoti, a nasal spray formulation of metoclopramide, for the relief of symptoms associated with acute and recurrent diabetic gastroparesis in adult women.

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.
