United States Patent and Trademark Office (USPTO) Grants Evoke Pharma a Formulation Patent Covering GIMOTI

The Company Will Submit for FDA Orange-Book Listing in the Near Term

SOLANA BEACH, Calif., April 20, 2023 (GLOBE NEWSWIRE) — Evoke Pharma, Inc. (NASDAQ: EVOK), a specialty pharmaceutical company focused primarily on treatments for gastrointestinal (GI) diseases with an emphasis on GIMOTI® (metoclopramide) nasal spray, announced that the United States Patent and Trademark Office (USPTO) issued US patent No. 11,628,150 under the title “Nasal Formulations of Metoclopramide.”

This patent expires in 2029 and covers the nasal solution of metoclopramide and its characteristics when formulated. The patent augments Evoke’s existing patent portfolio, which includes U.S. Food and Drug Administration (FDA) Orange Book-listed patents and other patents in the EU, Japan, Canada, and Mexico. The Company will seek to list this patent in the FDA Orange-Book in the near term.

“We view this patent approval and the others we’ve received to date from the USPTO as evidence of the innovation behind our product, GIMOTI and its significant contribution to the GI community, particularly patients,” commented Matt D’Onofrio, President & COO. “This patent will continue to protect GIMOTI’s proprietary route of administration which is incredibly important to our commercial efforts,” Mr. D’Onofrio concluded.

About Evoke Pharma, Inc.
Evoke is a specialty pharmaceutical company focused primarily on the development of drugs to treat GI disorders and diseases. The company developed, commercialized and markets GIMOTI, a nasal spray formulation of metoclopramide, for the relief of symptoms associated with acute and recurrent diabetic gastroparesis in adults. 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 GI symptoms as well as other systemic complications. The gastric delay caused by gastroparesis can compromise absorption of orally administered medications. Prior to FDA approval to commercially market GIMOTI, metoclopramide was only available in oral and injectable formulations and remains the only drug currently approved in the United States to treat gastroparesis.

Important Safety Information
WARNING: TARDIVE DYSKINESIA

• Metoclopramide can cause tardive dyskinesia (TD), a serious movement disorder that is often irreversible. The risk of developing TD increases with duration of treatment and total cumulative dosage.
• Discontinue GIMOTI in patients who develop signs or symptoms of TD. In some patients, symptoms may lessen or resolve after metoclopramide is stopped.
• Avoid treatment with metoclopramide (all dosage forms and routes of administration) for longer than 12 weeks because of the increased risk of developing TD with longer-term use.

GIMOTI is not recommended for use in:

• Pediatric patients due to the risk of developing tardive dyskinesia (TD) and other extrapyramidal symptoms as well as the risk of methemoglobinemia in neonates.
• Moderate or severe hepatic impairment (Child-Pugh B or C), moderate or severe renal impairment (creatinine clearance less than 60 mL/minute), and patients concurrently using strong CYP2D6 inhibitors due to the risk of increased drug exposure and adverse reactions.

GIMOTI is contraindicated:

• In patients with a history of tardive dyskinesia (TD) or a dystonic reaction to metoclopramide.
• When stimulation of gastrointestinal motility might be dangerous (e.g., in the presence of gastrointestinal hemorrhage, mechanical obstruction, or perforation).
• In patients with pheochromocytoma or other catecholamine-releasing paragangliomas. Metoclopramide may cause a hypertensive/pheochromocytoma crisis, probably due to release of catecholamines from the tumor.
• In patients with epilepsy. Metoclopramide may increase the frequency and severity of seizures.
• In patients with hypersensitivity to metoclopramide. Reactions have included laryngeal and glossal angioedema and bronchospasm.

Potential adverse reactions associated with metoclopramide include Tardive dyskinesia (TD), other extrapyramidal effects (EPS), parkinsonism symptoms, motor restlessness, neuroleptic malignant syndrome (NMS), depression, suicidal ideation and suicide, hypertension, fluid retention, hyperprolactinemia, effects on the ability to drive and operate machinery. Most common adverse reactions (≥5%) for GIMOTI are: dysgeusia, headache, and fatigue. These are not all of the possible side effects of GIMOTI. Call your doctor for medical advice about whether you should take GIMOTI and the possible risk factors and side effects. You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
