Pacira Announces FDA Advisory Committee Meeting to Review sNDA for EXPAREL® as a Nerve Block for Regional Analgesia
“We believe our robust dataset supports the expansion of the EXPAREL label to include nerve block and we look forward to a productive discussion with the advisory committee,” said
The sNDA filing is based on positive data from a Phase 3 study of EXPAREL in femoral nerve block for total knee arthroplasty (lower extremity) and a Phase 3 study of EXAREL in brachial plexus block for shoulder surgeries (upper extremity). It includes data from eight company-sponsored studies with safety and pharmacokinetic data through 120 hours. In addition, the sNDA includes data from two investigator-initiated studies that provide additional experience in smaller, peripheral nerve block settings.
The AADPAC reviews and evaluates available data concerning the safety and effectiveness of marketed and investigational human drug products for use in anesthesiology and surgery and makes appropriate recommendations to the Commissioner of Food and Drugs.
Important Safety Information
EXPAREL is contraindicated in obstetrical paracervical block anesthesia. In clinical trials, the most common adverse reactions (incidence ≥10%) following EXPAREL administration were nausea, constipation, and vomiting. EXPAREL is not recommended to be used in the following patient population: patients <18 years old and/or pregnant patients. Because amide-type local anesthetics, such as bupivacaine, are metabolized by the liver, EXPAREL should be used cautiously in patients with hepatic disease. Patients with severe hepatic disease, because of their inability to metabolize local anesthetics normally, are at a greater risk of developing toxic plasma concentrations. EXPAREL is not recommended for the following types or routes of administration: epidural, intrathecal, regional nerve blocks, or intravascular or intra-articular use. Non-bupivacaine-based local anesthetics, including lidocaine, may cause an immediate release of bupivacaine from EXPAREL if administered together locally. The administration of EXPAREL may follow the administration of lidocaine after a delay of 20 minutes or more. Formulations of bupivacaine other than EXPAREL should not be administered within 96 hours following administration of EXPAREL. Central Nervous System (CNS) Reactions: There have been reports of adverse neurologic reactions with the use of local anesthetics. These include persistent anesthesia and paresthesias. CNS reactions are characterized by excitation and/or depression. Cardiovascular System Reactions: Toxic blood concentrations depress cardiac conductivity and excitability which may lead to dysrhythmias sometimes leading to death. Allergic Reactions: Allergic-type reactions (eg, anaphylaxis and angioedema) are rare and may occur as a result of hypersensitivity to the local anesthetic or to other formulation ingredients. Chondrolysis: There have been reports of chondrolysis (mostly in the shoulder joint) following intra-articular infusion of local anesthetics, which is an unapproved use.
