Pacira Announces FDA Acceptance of sNDA for Exparel Nerve Blocks to Produce Regional Analgesia in Lower Extremity Procedures

TAMPA, Fla., March 29, 2023 (GLOBE NEWSWIRE) — Pacira BioSciences, Inc. (Nasdaq: PCRX), the industry leader in its commitment to non-opioid pain management and regenerative health solutions, today announced the U.S. Food and Drug Administration (FDA) has accepted the submission of its supplemental new drug application (sNDA) seeking expansion of the EXPAREL label to include both single-dose sciatic nerve block in the popliteal fossa as well as femoral nerve block in the adductor canal. The expected action date by the FDA under the Prescription Drug User Fee Act (PDUFA) is November 13, 2023.

The sNDA is supported by two successful Phase 3 studies in which EXPAREL achieved statistically significant and clinically meaningful reductions in postsurgical pain and opioid consumption through 96 hours compared with bupivacaine HCl following lower extremity surgical procedures including bunionectomy and total knee arthroplasty. In both studies EXPAREL was well tolerated with a safety profile consistent with bupivacaine HCl.

“We believe these positive datasets provide the basis for broadening the EXPAREL label to include both sciatic and femoral nerve blocks, which represents the opportunity to manage pain with a single 10 mL dose of EXPAREL for more than 3 million lower extremity procedures annually,” said Dave Stack, chief executive officer and chairman of Pacira BioSciences. “Importantly, this potential approval would give clinicians a safe and effective tool to provide four days of postsurgical pain control, reduce opioid requirements, and continue to migrate relevant orthopedic procedures to the outpatient setting.”

EXPAREL is currently indicated for single-dose infiltration in patients aged 6 years and older to produce postsurgical local analgesia and in adults as an interscalene brachial plexus nerve block to produce postsurgical regional analgesia. Since initial approval in 2011, more than 12 million U.S. patients have been treated with EXPAREL.

About Pacira

Pacira BioSciences, Inc. (Nasdaq: PCRX) is committed to providing a non-opioid option to as many patients as possible to redefine the role of opioids as rescue therapy only.

About EXPAREL^®

EXPAREL (bupivacaine liposome injectable suspension) is indicated in patients 6 years of age and older for single-dose infiltration to produce postsurgical local analgesia, and in adults as an interscalene brachial plexus nerve block to produce postsurgical regional analgesia. Safety and efficacy have not been established in other nerve blocks. The product combines bupivacaine with multivesicular liposomes, a proven product delivery technology that delivers medication over a desired time period. EXPAREL represents the first and only multivesicular liposome local anesthetic that can be utilized in the peri- or postsurgical setting. By utilizing the multivesicular liposome platform, a single dose of EXPAREL delivers bupivacaine over time, providing significant reductions in cumulative pain scores with up to a 78 percent decrease in opioid consumption; the clinical benefit of the opioid reduction was not demonstrated. Additional information is available at www.EXPAREL.com.

Important Safety Information about EXPAREL for Patients

EXPAREL should not be used in obstetrical paracervical block anesthesia. In studies in adults where EXPAREL was injected into a wound, the most common side effects were nausea, constipation, and vomiting. In studies in adults where EXPAREL was injected near a nerve, the most common side effects were nausea, fever, and constipation. In the study where EXPAREL was given to children, the most common side effects were nausea, vomiting, constipation, low blood pressure, low number of red blood cells, muscle twitching, blurred vision, itching, and rapid heartbeat. EXPAREL can cause a temporary loss of feeling and/or loss of muscle movement. How much and how long the loss of feeling and/or muscle movement depends on where and how much of EXPAREL was injected and may last for up to 5 days. EXPAREL is not recommended to be used in patients younger than 6 years old for injection into the wound, for patients younger than 18 years old for injection near a nerve, and/or in pregnant women. Tell your health care provider if you or your child has liver disease, since this may affect how the active ingredient (bupivacaine) in EXPAREL is eliminated from the body. EXPAREL should not be injected into the spine, joints, or veins. The active ingredient in EXPAREL can affect the nervous system and the cardiovascular system; may cause an allergic reaction; may cause damage if injected into the joints; and can cause a rare blood disorder.
