First study to show Gimoti's potential as supportive care for GLP-1 therapy

SOLANA BEACH, Calif., Oct. 28, 2024 (GLOBE NEWSWIRE) -- Evoke Pharma, Inc. (NASDAQ:EVOK), a specialty pharmaceutical company focused on developing treatments for gastrointestinal (GI) diseases, with a particular emphasis on GIMOTI^® (metoclopramide) nasal spray, together with EVERSANA, a leading provider of global commercial services to the life sciences industry, today announced the presentation of data for GLP-1 users with diabetic gastroparesis using GIMOTI at the American College of Gastroenterology (ACG) 2024 Annual Meeting.

The real-world retrospective study evaluated the impact of GIMOTI (metoclopramide nasal spray) in patients with diabetic gastroparesis (DGP) who were concurrently using GLP-1 receptor agonists. GLP-1 drugs are commonly prescribed for type 2 diabetes, and with the approval of GLP-1 medications, there have been increasing reports of these drugs exacerbating GI symptoms, specifically gastroparesis. GLP-1 medications function, in part, by causing delayed gastric emptying. Delayed gastric emptying, in the absence of mechanical obstruction, is the definition of gastroparesis. In a recent National Institute of Health (NIH) study (https://pubmed.ncbi.nlm.nih.gov/38399414/), an estimated 5.1% of patients in their study (n=10,328) on GLP-1 medications had gastroparesis.

The GIMOTI study compared healthcare resource utilization (HRU) between patients using GIMOTI nasal metoclopramide (NMCP) and those on oral metoclopramide (OMCP), specifically focusing on individuals with a prior GLP-1 prescription. Significant reductions across a collection of outcomes were observed in patients treated with GIMOTI versus oral metoclopramide.

Key Study Findings Presented at ACG 2024:

• Patients with prior GLP-1 history had reduced HRU after taking NMCP
  • In NMCP patients, all-cause emergency department (ED) visits decreased by 55% (mean [SD]: 0.25 [1.13] post-index vs. 0.55 [1.30] pre-index; p=0.063); and
  • DGP-related ED visits decreased by 28% (mean [SD]: 0.18 [0.99] post-index vs. 0.25 [1.28] pre-index; p=0.203).
• In patients taking GLP-1, those that took NMCP had fewer healthcare visits compared to those taking OMCP
  • All-cause and DGP-related ED visits were 91% lower (cIRR: 0.09, 95% CI: 0.01, 0.42; p=0.001) and 89% lower (cIRR: 0.11, 95% CI: 0, 0.93; p=0.046) for NMCP vs. OMCP; and
  • All-cause Hospital Outpatient visits were 89% lower (cIRR = 0.11, 95% CI: 0.01, 0.73; p = 0.032)
  • All-cause and DGP-related office visits were 41% lower (cIRR: 0.59, 95% CI: 0.37, 0.94; p=0.027) and 66% lower (cIRR: 0.34, 95% CI: 0.017, 0.65; p=0.001) for NMCP vs. OMCP.
• NMCP can be used to effectively treat patients with gastroparesis taking GLP-1 treatment and avoid costly healthcare visits
  • All-cause clinic, outpatient, and inpatient visits showed similar trends favoring NMCP vs. OMCP.
  • In DGP patients with a prior claim for GLP-1, NMCP use was associated with numerically and significantly reduced all-cause and DGP-related HRU compared to pre-treatment utilization and OMCP-treated controls.

"This data is particularly encouraging given the rising number of patients using GLP-1 agonists for diabetes, many of whom also suffer from gastroparesis," said Matt D'Onofrio, CEO of Evoke Pharma. "Our goal is to provide data regarding Gimoti as supportive care for diabetic gastroparesis for those also on GLP-1 agonists. This study, combined with the earlier real-world data presented at key conferences, reinforces GIMOTI's potential to improve outcomes for patients and reduce the overall financial burden on the healthcare system."

The study's specific cohort consisted of 92 total patients between the nasal metoclopramide (NMCP, N=51) and oral metoclopramide (OMCP, N=41) groups. The NMCP group had a slightly older average age (55.1 years) compared to the OMCP group (53.1 years). A notable portion of the NMCP group (31.4%) had experienced hospitalizations or emergency department visits before treatment, compared to 19.5% in the OMCP group.

In a separate study, a post-hoc analysis focused on safety data for a female subgroup from a previous Phase 3 study that included 36 women using GLP-1 drugs during the 28-day study. Among these, 13 were treated with GIMOTI and 23 with placebo. The majority (94%) of the participants completed the study, with no serious adverse events reported in either group. This analysis indicated no series safety issues and a trend toward nausea improvement when GLP-1 drugs were used with NMCP.

"Our continued focus is helping patients that have gastroparesis and diabetes. The fact that up to 20 million patients (KFF Health Tracking Poll (April 23-May 1, 2024) (kff.org/KFF Health Tracking Poll)) may have taken or are currently taking GLP-1s for their diabetes, indicates this is an important patient constituency the medical community needs to monitor and address," said Chris Quesenberry, Chief Commercial Officer of Gimoti. "Evoke Pharma, through its clinical development program and real-world evidence studies, is uniquely positioned to provide clinicians with information that may inform treatment decisions. This study provides insight that clinicians who treated their patients with diabetic gastroparesis, who were also taking a GLP-1, benefitted in taking GIMOTI^®, an innovative, non-oral therapy that does not rely on a dysfunctional gut to work."

The results presented at ACG 2024 build on a growing body of real-world data that underscores GIMOTI's ability to significantly reduce HRU in patients with diabetic gastroparesis. Earlier studies presented at Digestive Disease Week (DDW) 2024 and ACG 2023 demonstrated that patients treated with GIMOTI showed fewer hospitalizations, emergency department visits, and physician office visits compared to those using oral metoclopramide. Also, these studies highlighted that GIMOTI reduced healthcare costs by over $15,000 per patient in a six-month period compared to oral metoclopramide​​.

"These studies further confirm the important role of GIMOTI in managing diabetic gastroparesis and supports its use for patients concurrently on GLP-1 agonists," said Dr. Michael Cline, Medical Director of the Gastroparesis Clinic at Cleveland Clinic, an author of the study. "In my practice, I've treated patients arriving with gastroparesis while on a GLP-1. This data demonstrates a significant reduction in emergency room visits, office visits, and overall healthcare resource utilization, which not only improves patient outcomes but also reduces the strain on healthcare systems. The nasal delivery of metoclopramide offers a distinct advantage for patients with delayed gastric emptying, ensuring they receive the relief they need without the complications or unknown absorption associated with oral medications."

EVERSANA was named Evoke's commercialization partner to support commercialization efforts of GIMOTI, first in 2020 and then an extended partnership was announced in February 2022.

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.
