SurfaxinTreatment for Respiratory Distress Syndrome
Discovery Labs Submits Surfaxin Complete Response to FDA
WARRINGTON, Pa., Sept. 6, 2011 /PRNewswire/ -- Discovery Labs, Inc. today announced that, on September 2, 2011, it submitted its Complete Response to the 2009 Complete Response Letter issued by the U.S. Food and Drug Administration (FDA) for Surfaxin (lucinactant) for the prevention of respiratory distress syndrome (RDS) in premature infants. Discovery Labs believes that the FDA will designate the Complete Response as a Class 2 resubmission of the Surfaxin New Drug Application (NDA), which would result in a target review period of six months and potential approval of Surfaxin in the first quarter of 2012. If approved, Surfaxin would represent the first synthetic, peptide-containing surfactant for use in neonatal medicine.
In April 2009, Discovery Labs received from the FDA a Complete Response Letter, which contains the requirements that must be addressed to gain U.S. marketing approval for Surfaxin. The safety and efficacy of Surfaxin for the prevention of RDS in premature infants has been previously demonstrated in a large, multinational Phase 3 clinical program. The Complete Response Letter did not question the quality of the clinical trial data or call for additional clinical trials to demonstrate the safety or efficacy of Surfaxin. The Complete Response Letter focused primarily on certain aspects of an important quality control release and stability test for Surfaxin, the fetal rabbit biological activity test (BAT). Discovery Labs believes that a key step to potentially gain FDA marketing approval for Surfaxin is to satisfy the FDA's requirements for final validation of the BAT. Accordingly, Discovery Labs has completed a comprehensive preclinical program intended to meet the FDA's requirements and has included these data in its Complete Response.
"We have had several productive interactions with the FDA related to our Surfaxin comprehensive preclinical program to support the Complete Response," said W. Thomas Amick, Chairman of the Board and Chief Executive Officer, Discovery Labs. "Based on these interactions, we believe we have addressed all requirements of the 2009 Complete Response Letter."
In accordance with FDA guidance, Discovery Labs expects that it will be notified within 14 days that the Complete Response is deemed "complete" and the classification of the submission, which, under the Prescription Drug User Fee Act, will determine the target action date (PDUFA date) for the FDA to complete its review of the Surfaxin NDA. Upon receipt of this notification, Discovery Labs plans to hold an investor conference call to provide an overview of the comprehensive preclinical program and the Surfaxin Complete Response.
DISCLOSURE NOTICE: The information in this press release includes certain "forward-looking" statements, including about the remaining steps to potentially gain FDA approval of Surfaxin for the prevention of RDS in premature infants and the timing of the anticipated FDA review period. The final results of these and other ongoing activities could vary materially from Discovery Labs' expectations and could adversely affect the chances for approval of Surfaxin for the prevention of RDS in premature infants. These activities and the ultimate outcomes are subject to a variety of risks and uncertainties, including but not limited to risks that (i) although Discovery Labs believes that the FDA will deem Discovery Labs' formal response to be "complete" under its guidelines, the FDA may determine that the Complete Response filed by Discovery Labs is not "complete", potentially requiring Discovery Labs to conduct additional activities before it can re-file, if at all, the Complete Response, (ii) although the FDA guidance indicates that (x) the FDA will determine the class of the Complete Response submission and the PDUFA date and notify Discovery Labs within 14 days after receipt of the submission, and (y) assuming that the FDA determines that the Complete Response is a Class 2 resubmission, the FDA will complete its review of the NDA within six months after receipt of the submission, the FDA may not complete its activities within the time frames included in the FDA guidance, (iii) although Discovery Labs believes that it has been successful in generating the additional data and other information requested by the FDA, the FDA may not be satisfied and may require Discovery Labs to perform further studies or undertake other activities that are presently not contemplated by Discovery Labs, (iv) the FDA may not be satisfied with (A) Discovery Labs' responses to other items identified in the 2009 Complete Response Letter, or (B) the results of anticipated pre-approval inspections of Discovery Labs' manufacturing and analytical facilities and the facilities of third party laboratories and manufacturers of active pharmaceutical ingredients (APIs) and other materials used in the manufacture of Surfaxin, and, as a result, Discovery Labs may be unable to gain approval of Surfaxin, if at all, within the time frame indicated above, (v) Discovery Labs may identify problems that have not yet been discovered, and (vi) the FDA could impose additional requirements to gain approval of Surfaxin. Any failure to satisfy the FDA's requirements could significantly delay, or preclude outright, approval of Surfaxin, which could potentially prevent the approval of Discovery Labs' other products.
