Eagle Pharmaceuticals to Present Additional Data from Phase III Trial Demonstrating Sustained Response of Amisulpride for the Rescue Treatment of Postoperative Nausea and Vomiting (PONV) at the Upcoming ASPAN 2024 National Conference in Orlando, Florida

WOODCLIFF LAKE, N.J., April 15, 2024 (GLOBE NEWSWIRE) -- Eagle Pharmaceuticals, Inc. (NASDAQ:EGRX) ("Eagle" or the "Company") today announced that data from the Company's Phase III trial demonstrating the sustained response of amisulpride for the rescue treatment of postoperative nausea and vomiting ("PONV") will be presented at the upcoming American Society of PeriAnesthesia Nurses (ASPAN) 2024 National Conference, which is being held April 14-18, 2024, in Orlando, Florida.

The data being presented relate to a prespecified pharmacokinetic ("PK") subset of patients from a Phase III, randomized, multicenter, double-blind, placebo-controlled, parallel-group study in adult surgical patients with moderate to high risk of PONV who failed antiemetic prophylaxis. The purpose of the analysis was to evaluate the plasma concentrations of a single dose of IV amisulpride 10 mg for rescue treatment of PONV.

The PK data from a subset of patients in this Phase III trial demonstrate that supratherapeutic amisulpride plasma levels can be maintained for at least 24 hours after a single 10 mg dose, which may resultin clinically meaningful, sustained antiemetic effect for PONV rescue when compared to the placebo arm.

"The PK data from this subset of patients in this Phase 3 study demonstrate that a single treatment with amisulpride is capable of delivering a sustained response, which we believe is particularly useful in the rescue setting where patients have already failed antiemetic prophylaxis therapy," stated Mike Greenberg, MD, Vice President of Medical Affairs at Eagle Pharmaceuticals. "Based on what we believe to be encouraging results and corresponding PK data, we expect more healthcare providers to recognize the potential of PONV rescue treatment with amisulpride to enhance confidence in post-surgery and discharge outcomes."

Details of the poster presentation are as follows:

Indication and Important Safety Information for Barhemsys^® (amisulpride) Injection⁴

Indication

Barhemsys is a selective dopamine-2 (D₂) and dopamine-3 (D₃) receptor antagonist indicated in adults for prevention of PONV either alone or in combination with an antiemetic of a different class and treatment of PONV in patients who have received antiemetic prophylaxis with an agent of a different class or have not received prophylaxis.

Important Safety Information

Contraindication

Barhemsys is contraindicated in patients with known hypersensitivity to amisulpride. 

QT Prolongation 

Barhemsys causes dose- and concentration-dependent prolongation of the QT interval. The recommended dosage is 10 mg as a single intravenous (IV) dose infused over 1 to 2 minutes. 

Avoid Barhemsys in patients with congenital long QT syndrome and in patients taking droperidol. 

Electrocardiogram (ECG) monitoring is recommended in patients with pre-existing arrhythmias/cardiac conduction disorders, electrolyte abnormalities (e.g., hypokalemia or hypomagnesemia), congestive heart failure, and in patients taking other medicinal products (e.g., ondansetron) or with other medical conditions known to prolong the QT interval. 

Adverse Reactions 

The most common adverse reaction, reported in ≥ 2% are:

• Prevention of PONV: increased blood prolactin concentrations, chills, hypokalemia, procedural hypotension, and abdominal distension.
• Treatment of PONV: infusion site pain.

To report SUSPECTED ADVERSE REACTIONS, contact Acacia Pharma at 1-877-357-9237 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

Use in Specific Populations 

Pregnancy

Available data with amisulpride use in pregnant women are insufficient to establish a drug associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes.

Lactation 

Amisulpride is present in human milk. There are no reports of adverse effects on the breastfed child and no information on the effects of amisulpride on milk production. 

Barhemsys may result in an increase in serum prolactin levels, which may lead to a reversible increase in maternal milk production. In a clinical trial, serum prolactin concentrations in females (n=112) increased from a mean of 10 ng/mL at baseline to 32 ng/mL after Barhemsys treatment and from 10 ng/mL to 19 ng/mL in males (n=61). No clinical consequences due to elevated prolactin levels were reported. 

To minimize exposure to a breastfed infant, lactating women may consider interrupting breastfeeding and pumping and discarding breast milk for 48 hours after receiving a dose of Barhemsys. 

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

No overall differences in safety or effectiveness were observed between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

Drug Interactions 

• Barhemsys causes dose- and concentration-dependent QT prolongation. To avoid potential additive effects, avoid use of Barhemsys in patients taking droperidol. 
• ECG monitoring is recommended in patients taking other drugs known to prolong the QT interval (e.g., ondansetron).
• Reciprocal antagonism of effects occurs between dopamine agonists (e.g., levodopa) and Barhemsys. Avoid using levodopa with Barhemsys.
