Pacira Receives Complete Response Letter from FDA for sNDA Seeking Approval of EXPAREL® Use in Nerve Block to Provide Postsurgical Analgesia

PARSIPPANY, N.J.--(BUSINESS WIRE)--Mar. 2, 2015-- Pacira Pharmaceuticals, Inc. (NASDAQ: PCRX) today announced the receipt of a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) following a review of its supplemental New Drug Application (sNDA) for the use of EXPAREL® (bupivacaine liposome injectable suspension) in nerve block to provide postsurgical analgesia. Pacira will immediately schedule an End-of-Review meeting with the Division of Anesthesia, Analgesia and Addiction Products of the Center for Drug Evaluation and Research to discuss the contents of the CRL.

“We are reviewing the contents of the CRL and will work actively with the FDA to bring this important new indication to our core and growing business in infiltration,” said Dave Stack, president, chief executive officer and chairman of Pacira. “Prescribed opioids in the acute care, postsurgical setting lead to chronic use and abuse in approximately one out of every 15 surgery patients in the United States; we remain committed to providing patients with long-acting, non-opioid analgesic options, like EXPAREL, to treat their pain while minimizing the risk of opioid-related adverse events. We look forward to finding solutions to address this public healthcare problem together with the FDA.”

EXPAREL is currently indicated for single-dose infiltration into the surgical site to produce postsurgical analgesia. The product combines bupivacaine with DepoFoam®, 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 DepoFoam platform, a single dose of EXPAREL delivers bupivacaine over time, providing significant reductions in cumulative pain scores with a 45 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

EXPAREL is contraindicated in obstetrical paracervical block anesthesia. EXPAREL has not been studied for use in patients younger than 18 years of age. 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. Other formulations of bupivacaine should not be administered within 96 hours following administration of EXPAREL. Monitoring of cardiovascular and neurological status, as well as vital signs should be performed during and after injection of EXPAREL as with other local anesthetic products. 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. In clinical trials, the most common adverse reactions (incidence greater-than or equal to 10%) following EXPAREL administration were nausea, constipation, and vomiting.
