Discovery Labs KL-4 Surfactant Anti-Inflammatory Data Published in Pediatric Research

WARRINGTON, Pa., July 29, 2008 (PRIME NEWSWIRE) -- Discovery Laboratories, Inc. (Nasdaq:DSCO), announces the publication in Pediatric Research of data from a pre-clinical research study conducted at the Nemours Research Lung Center, DuPont Hospital for Children. The data showed that KL-4 surfactant reduced the inflammatory response and improved cell survival and function in a human lung cell-culture injury model. Pediatric Research is a prominent peer reviewed journal that publishes results of significant clinical and laboratory studies intended for research-oriented pediatricians and faculty.

Respiratory inflammation is a primary component of many lung diseases. It is well established that inflammatory mediators in the lung damage the lung cells that make surfactant. Surfactants are compositions produced naturally in the lungs and are essential for breathing. Discovery Labs is focused on diseases in which inflammation or endogenous surfactant degradation plays an integral part in development of respiratory lung diseases, such as Acute Lung Injury, Acute Respiratory Failure, Bronchopulmonary Dysplasia, and Respiratory Distress Syndrome, Cystic Fibrosis, Asthma, and Chronic Obstructive Pulmonary Disorder.

The manuscript published in Pediatric Research is: Surfaxin (KL-4 surfactant) Protects Human Airway Epithelium from Hyperoxia (Zhu et al.) Pediatric Research. 64(2): 154-158, August 2008.

Conducted under the direction of Drs. Zhu, Miller, Chidekel, and Shaffer, the study examined whether KL-4 surfactant reduced markers of inflammation, damage and remodeling in human airway epithelia cells exposed to high concentrations of oxygen (hyperoxia), which causes lung injury. The study assessed the impact of exogenous surfactants, including KL-4 surfactant (Surfaxin(r)), on hyperoxic-induced lung injury in an in-vitro cell-culture model. The results concluded that KL-4 surfactant reduced inflammation and cell injury, resulting in improved cell survival and function compared with both a saline control as well as beractant (Survanta(r)), an animal-derived surfactant and currently the most frequently prescribed surfactant in the United States. Preliminary results from this study were previously presented at the Pediatric Academic Societies annual meeting in May 2007 and the European Society for Paediatric Research annual meeting in October 2007.

Dr. Thomas H. Shaffer, Director, Nemours Research Lung Center, commented, "These data are quite compelling and support a potentially novel mechanism of KL-4 surfactant, which may be clinically relevant in the treatment of several respiratory disorders where lung inflammation plays a central role."

Surfaxin(r), an investigational drug, is the subject of an Approvable Letter from the FDA for the prevention of Respiratory Distress Syndrome in premature infants. The publication listed above includes information that may be of interest to healthcare practitioners; however, the clinical relevance of this information has not been established.

About Discovery Labs and its Novel, KL-4 Surfactant Technology

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' KL-4 technology produces a peptide-containing synthetic surfactant that is structurally similar to pulmonary surfactant. KL-4 is a 21-amino acid peptide with structural similarities to pulmonary surfactant protein B (SP-B), the surfactant protein most important for normal respiratory function. KL-4 surfactant technology has the potential to be precisely formulated as a liquid instillate or aerosol. Discovery Labs believes that, with its proprietary technology, SRT has the potential, for the first time, to address a variety of respiratory diseases affecting neonatal, pediatric and adult patients.

SURFAXIN(r), the Company's lead product from its SRT pipeline, 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.
