Impax Laboratories, Inc. (NASDAQ: IPXL) today announced that the U.S. Food and Drug Administration (FDA) completed its re-inspection of the Company’s Hayward manufacturing facility in connection with the previously disclosed Form 483 issued in March 2012. In addition to the re-inspection, the FDA conducted a Pre-Approval Inspection (PAI) for RYTARY TM, as analytical method validation and a portion of the stability data were generated in Hayward, and a general Good Manufacturing Practices (GMP) inspection. At the conclusion of this inspection, the FDA issued a new Form 483 with twelve (12) observations, three (3) of which are designated as repeat observations from inspections that occurred prior to the Warning Letter. “We have committed significant resources in our efforts to meet FDA requirements and are clearly disappointed by this news,” said Larry Hsu, Ph.D., president and CEO, Impax Laboratories, Inc. “The analytical method assessment observations arose from our internal work and review as a part of the ongoing quality improvement program designed to assess and enhance our Quality Control Laboratory Analytical Methods and to ensure they meet or exceed internal and industry standards. Resolving the FDA concerns remains a top priority and we intend to complete this work as quickly as possible.” The Company is working diligently to address the observations raised by the FDA and will respond to these new observations within the fifteen (15) business day period from the receipt of the Form 483. Currently, the Company has not been informed by the FDA of the impact this latest Form 483 will have on the resolution or timing of resolving the warning letter or whether any further regulatory action may be taken as to its manufacturing operations. Until remedial action is complete and the FDA has confirmed compliance with current GMP, approval of pending and new applications listing the Hayward facility as a manufacturing location of finished dosage forms may be withheld.
