Pacira Pharmaceuticals, Inc. Announces EXPAREL™ Data to Be Presented at Upcoming Medical Meetings

PARSIPPANY, N.J., Oct. 11, 2011 /PRNewswire/ -- Pacira Pharmaceuticals, Inc. (Nasdaq: PCRX) today announced that new data highlighting the pain control and pharmacokinetic properties of EXPAREL™ (bupivacaine liposome extended-release injectable suspension), the company's lead investigational product for postsurgical pain management, will be presented during poster presentations at the 2011 Annual Meetings of the American Society of Anesthesiologists (ASA) and the American College of Clinical Pharmacy (ACCP) in Chicago and Pittsburgh, respectively.

Currently under review with the U.S. Food and Drug Administration, EXPAREL is an innovative long-acting bupivacaine that has been shown in multiple Phase 2 and Phase 3 clinical studies to provide prolonged postsurgical analgesia for up to 72 hours with a single-dose local administration at the surgical site. The drug combines bupivacaine with DepoFoam®, Pacira's proven product delivery technology that delivers medication over a desired time period.

"We have continued to execute on our strategy to present EXPAREL clinical data to key medical audiences and we are pleased that these data will be showcased at these important medical meetings," said Dave Stack, president and chief executive officer of Pacira Pharmaceuticals, Inc. "We look forward to sharing new comparative data highlighting the pain control advantages that EXPAREL offers, as well as pharmacokinetic data, with the pharmacy and anesthesiology communities, who we believe will find great utility in EXPAREL should it be approved later this year."

About Pacira

Pacira Pharmaceuticals, Inc. is an emerging specialty pharmaceutical company focused on the development, manufacture and commercialization of novel pharmaceutical products, based on its proprietary DepoFoam drug delivery technology, for use in hospitals and ambulatory surgery centers. In December 2010, Pacira announced that its New Drug Application (NDA) for EXPAREL (bupivacaine liposome extended-release injectable suspension), the company's most advanced investigational product candidate, had been accepted for filing by the U.S. Food and Drug Administration (FDA). The FDA has assigned a Prescription Drug User Fee Act (PDUFA) goal date of October 28, 2011 for the review of the EXPAREL NDA. EXPAREL is a bupivacaine-based product and has completed extensive Phase 3 clinical development for postsurgical analgesia by infiltration. EXPAREL consists of bupivacaine encapsulated in DepoFoam, which is designed to address the limitations of widely used medications by enhancing their dosing and/or administration profile. Additional information about Pacira is available at www.pacira.com.

About EXPAREL™

EXPAREL (bupivacaine liposome extended-release injectable suspension) is Pacira's proprietary drug candidate consisting of bupivacaine encapsulated in DepoFoam®, both of which are currently used separately in FDA-approved products. Bupivacaine is a well-characterized anesthetic/analgesic that has an established safety profile with more than 20 years of use in the United States. Market data indicate that there is an unmet medical need for a longer-acting anesthetic/analgesic for postsurgical pain management. Several Phase 2 and Phase 3 clinical trials have been completed for EXPAREL and suggest statistically significant reduction of pain in soft tissue and orthopedic surgery in different surgical models. Clinical data from Phase 3 trial 316 suggest that EXPAREL provides analgesia for up to 72 hours post-surgery, the primary endpoint for the trial. The safety of EXPAREL was evaluated in 10 randomized, double-blind, local administration into the surgical wound clinical studies involving 823 patients; the most common adverse events following EXPAREL administration were nausea, constipation, and vomiting.
