Surfaxin (Lucinactant) Long-Term Survival Advantage vs. Comparators Published in Pediatrics

Update: Surfaxin (lucinactant) Now FDA Approved - March 6, 2012

WARRINGTON, Pa., May 31, 2007 (PRIME NEWSWIRE) -- Discovery Laboratories, Inc. (Nasdaq:DSCO) announces publication of the one-year follow-up results from its SELECT and STAR Phase 3 clinical trials for Surfaxin(r), in Pediatrics, the premier medical journal for pediatric healthcare practitioners. The long-term data from the SELECT and STAR trials concluded that Surfaxin demonstrated a statistically significant survival advantage relative to existing animal-derived surfactants, Survanta(r) and Curosurf(r). Surfaxin is pending approval and has received an Approvable Letter from the United States Food and Drug Administration (FDA) for the prevention of RDS in premature infants.

The article published in Pediatrics is entitled: One-Year Follow-up of Very Preterm Infants Who Received Lucinactant for Prevention of Respiratory Distress Syndrome: Results from 2 Multicenter Randomized, Controlled Trials (Moya et al.) Pediatrics Vol. 119 No. 6 June 2007.

Fernando Moya, M.D., Chair of the SELECT study Steering Committee and Director of Neonatology at the Coastal Area Health Education Center, North Carolina, commented, "The long-term outcomes from the pooled analysis are particularly important because they suggest that a next-generation surfactant therapy, such as Surfaxin, may save more babies' lives while improving their chances for a healthy future. The prospective assessment of long-term outcomes from the SELECT and STAR trials is unique given direct comparisons between surfactant products. The data set from this recently published analysis sets a new bar for this category."

Key Data Highlights:

* Treatment with Surfaxin significantly improved survival (p=0.05) through one-year of life compared with animal-derived surfactants, Survanta and Curosurf.

* Surfaxin significantly improved survival (p=0.04) through one-year of life when directly compared with Curosurf, the current market leader in Europe and current market growth driver in United States.

* Although treatment with Surfaxin improved survival in preterm children, no differences in neurologic outcomes through one-year of life were observed between treatment groups, however, Surfaxin demonstrated a statistically significant (p less than or equal to 0.05) reduction in two important assessments of neurologic outcomes (reflex abnormality and gross tone) versus Survanta.

Robert J. Capetola, President and CEO of Discovery Labs, commented, "Publication of these data in Pediatrics represents an important validation of Surfaxin, the cornerstone of Discovery's broad SRT pipeline. The neonatal medical community has repeatedly indicated a strong interest in long-term outcomes assessment. No such assessment from the registration trials supporting use of currently prescribed animal-derived products has, to our knowledge, ever been conducted. Discovery is committed to provide this critically important information to the neonatal community. The article by Dr. Moya et al. supports a defined survival advantage for Surfaxin compared with current standard of care. We believe these long-term data will support significant differentiation for Surfaxin."

About Surfaxin

Surfaxin is a precision-engineered version of natural human lung surfactant and contains Discovery Labs' 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 the 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.

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(r), 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.
