SurfaxinTreatment for Respiratory Distress Syndrome
Update: Surfaxin (lucinactant) Now FDA Approved - March 6, 2012
Surfaxin Process Validation Batches Achieve Stability Milestone to Enable Filing of Response to FDA Approvable Letter
WARRINGTON, Pa., Oct. 1, 2007 (PRIME NEWSWIRE) -- Discovery Laboratories, Inc. today announces that its new Surfaxin (lucinactant) process validation batches have demonstrated acceptable stability at six months under Discovery Labs' comprehensive stability testing protocol. This six-month stability data will be included, along with other data and information, in a formal response to the U.S. Food and Drug Administrations' (FDA) April 2006 Approvable Letter for Surfaxin for the prevention of Respiratory Distress Syndrome (RDS) in premature infants. Discovery Labs remains on track to file its response to the FDA Approvable Letter in the October 2007 timeframe, followed by an anticipated six-month review cycle by the FDA for potential approval of the Surfaxin New Drug Application (NDA).
Discovery Labs manufactured three new Surfaxin process validation batches in 2007 after guidance was obtained from the FDA at a December 2006 meeting. At that meeting, Discovery Labs presented information regarding its comprehensive investigation and remediation of the April 2006 process validation stability failure. The meeting also established that Discovery Labs' new Surfaxin process validation batches must demonstrate acceptable stability through six-months prior to the filing of a formal response to the Approvable Letter. Since their manufacture, these new process validation batches have been monitored in accordance with a comprehensive stability testing protocol that complies with International Conference on Harmonization (ICH) guidelines, have demonstrated acceptable stability through six months, and will continue to be monitored through Surfaxin proposed shelf-life.
The FDA Approvable Letter for Surfaxin primarily focuses on the CMC (chemistry, manufacturing and controls) section of the Surfaxin NDA. The Approvable Letter does not require any additional clinical trials, but requests additional information predominantly involving drug product specifications and stability, analytical methods and related controls. In December 2006, Discovery Labs met with the FDA to clarify certain of the key CMC matters identified in the Approvable Letter, and obtain guidance on the appropriate path to potentially gain approval of Surfaxin. The FDA's guidance provided a defined pathway for Discovery Labs to generate additional data from selected experiments that are essential for approval of Surfaxin.
Discovery Labs believes it has made significant progress in addressing the outstanding CMC issues identified in the Approvable Letter and is currently focused on generating, compiling and analyzing supporting information for submission to the FDA. Discovery Labs believes that its progress to date, including achieving the six month process validation stability milestone, supports the filing of the formal response to the Approvable Letter in the October 2007 timeframe.
Surfaxin, is a precision-engineered version of natural human lung surfactant and contains Discovery Labs' novel KL-4 peptide. Surfaxin, administered as a liquid-instillate, represents a potential alternative to the commercially available animal-derived surfactants. Data from Discovery Labs' pivotal, multinational SELECT study demonstrate that Surfaxin is significantly more effective in the prevention of RDS and results in improved survival (continuing through at least one year of life) and other outcomes versus comparator surfactants. The SELECT and STAR (a supportive Phase 3 study) trials, as well as a pooled Phase 3 analysis, have been presented at several international medical meetings and the results from the two studies were published in Pediatrics. In addition, top-line results from Discovery Labs' Phase 2 clinical trial for the prevention and treatment of BPD suggested that infants treated with up to five incremental standard doses of Surfaxin tended to have a lower incidence of death or BPD, a higher survival rate through 36 weeks post-menstrual age, and fewer days on mechanical ventilation. Discovery Labs recently initiated a Phase 2 clinical trial evaluating the use of Surfaxin in children up to two years of age suffering from Acute Respiratory Failure (ARF). This new trial will explore the expanded application of surfactant therapy to pediatric critical care medicine.
Disclosure Notice: The information in this press release includes certain "forward-looking" statements relating to, among other things, the remaining steps necessary for FDA approval of Surfaxin for the prevention of RDS in premature infants, including information being prepared for inclusion in Discovery Labs' formal response to the Approvable Letter and the potential results of both Discovery Labs' comprehensive manufacturing investigation and the ongoing release and stability testing of the investigational batches and the new process validation batches. Although Discovery Labs is encouraged by the progress that it believes it has made to date, the development of data and other relevant information for the formal response to the Approvable Letter, including the release and stability testing of the investigational batches and the new process validation batches, are ongoing and the final results of these efforts could vary materially from the observations and results obtained to date. Discovery Labs currently believes that it will succeed in submitting its formal response to the Approvable Letter, with six months of successful stability data for the new process validation batches, within the timeframe indicated above, subject, however, to a variety of risks, including that (i) Discovery Labs may not succeed in completing its experiments or developing the data and other information necessary for the formal response, (ii) the new process validation batches may in the future fail to meet designated stability or other release parameters, and (iii) Discovery Labs may identify unforeseen problems that have not yet been discovered. The reader of this release should understand that the failure to develop all necessary information required to respond to the Approvable Letter, including at least six months of stability data for the new process validation batches, could result in significant delays or additional requirements and potentially prevent the approval of Surfaxin or other Discovery Labs products.
About Discovery Labs
Discovery Laboratories, Inc. is a biotechnology company developing Surfactant Replacement Therapies (SRT) for respiratory diseases. Surfactants are produced naturally in the lungs and are essential for breathing. Discovery Labs' technology produces a precision-engineered surfactant that is designed to closely mimic the essential properties of natural human lung surfactant. Discovery Labs believes that its proprietary SRT pipeline has the potential to advance respiratory medicine and address a variety of respiratory diseases affecting neonatal, pediatric and adult patients.
Discovery Labs' lead product candidate, Surfaxin, is the subject of an Approvable Letter from the FDA for the prevention of Respiratory Distress Syndrome in premature infants. Surfaxin is also being developed for other neonatal and pediatric indications. Aerosurf(tm), Discovery Labs' aerosolized SRT, is being developed to potentially obviate the need for intubation and conventional mechanical ventilation and holds the promise to significantly expand the use of surfactants in respiratory medicine.
