Evoke Pharma Granted FDA Market Exclusivity for GIMOTI®

Reinforces Company’s Robust Intellectual Property Portfolio

SOLANA BEACH, Calif., April 26, 2022 (GLOBE NEWSWIRE) — Evoke Pharma, Inc. (NASDAQ: EVOK), a specialty pharmaceutical company focused primarily on treatments for gastrointestinal (GI) diseases, today announced that it has been granted new drug product exclusivity by the U.S. Food and Drug Administration (FDA) for GIMOTI (metoclopramide) nasal spray. Evoke now has exclusive marketing rights over a period of three (3) years from the original date of approval under the Hatch-Waxman Act to protect the product from generic drug competition. Enacted by Congress in 1984, the Hatch-Waxman Amendments include provisions that involve patents and exclusivities related to new drug applications.  

In addition to the market exclusivity, Evoke maintains a robust patent estate, with currently two Orange book-listed patents entitled “Nasal Formulations of Metoclopramide,” U.S. Patent No. 11,020,361, and U.S. Patent No. 8,334,281, that expire in 2029 and 2030, respectively. The Company has also been granted gender-specific patents in the E.U., Japan, and Mexico with coverage until 2032. Furthermore, the Company has other pending patent applications with individual expiration dates of 2032, 2037, and 2038, if approved.

“Receiving marketing exclusivity rights from the FDA for GIMOTI further establishes our proprietary concept of delivering an effective medication through the nasal pathway for the treatment of symptoms associated with diabetic gastroparesis. We are excited to continue our mission of getting GIMOTI to patients who are in need of a non-oral treatment for gastroparesis and capitalize on this large and growing market opportunity in the U.S.,” commented Matt D’Onofrio, MBA, Evoke Pharma Chief Business Officer.

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.

About GIMOTI^® (metoclopramide) nasal spray
GIMOTI is indicated for the relief of symptoms in adults with acute and recurrent diabetic 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.
