Full Press Release Details
Orphan Drug Designation for
Treatment of Cystic Fibrosis
Warrington, PA, November 1, 2010 -
Discovery Laboratories, Inc. (Nasdaq: DSCO), today announced that the
Office of Orphan Products Development of the United States Food and Drug
Administration (FDA) has granted orphan drug designation to Discovery's KL4 surfactant
for the treatment of cystic fibrosis (CF). Orphan designation
provides for up to seven years of U.S. market drug product exclusivity for the
designated indication following marketing authorization.
Thomas F. Miller, Discovery Labs' Chief Operating Officer commented, "To date,
Discovery Labs has successfully procured orphan designations for several
respiratory disease targets in both the U.S. and Europe. We are pleased that the
FDA's Office of Orphan Products Development has granted orphan designation for
surfactant for CF treatment."
caused by a genetic mutation that leads to the production of thick, viscous
mucus that is difficult to clear from the airways of the lung. The
abnormal mucus allows for chronic airway infections that lead to airway
destruction, decreased lung function, and ultimately, death. Dr.
Miller continued, "Previous preclinical and exploratory clinical studies suggest
that surfactant may improve mucociliary clearance, thereby potentially
preventing further compromise of lung function. Our preclinical and recent
clinical experience suggests that CF may be a viable therapeutic target for our
aerosolized KL4 surfactant
recently announced the completion of a double-blind, randomized crossover Phase
2a study that evaluated the safety, tolerability and effectiveness of
aerosolized KL4 surfactant
in a CF population. The trial was presented at the 2010 North
American Cystic Fibrosis Conference, and the principle investigator concluded
that aerosolized KL4 surfactant
delivery was feasible to CF patients, was generally safe and well tolerated, was
not associated with serious adverse events (SAEs) and demonstrated evidence of
pharmacologic response via improvement in mucociliary clearance (MCC) versus
patient baseline. Previously, Discovery reported that KL4 surfactant
improved MCC in an established pre-clinical model designed to assess drug effect
on mucociliary clearance.
Orphan Drug Act is intended to assist and encourage companies to develop safe
and effective therapies for the treatment of rare diseases and
disorders. Orphan drug designation in the United States is awarded to
compounds that offer potential therapeutic value in the treatment of rare
diseases, defined as those affecting fewer than 200,000 Americans. If the
company complies with certain FDA specifications and receives marketing approval
for the designated indication, orphan drug designation qualifies the sponsor for
up to seven years of marketing exclusivity, tax credits related to clinical
research, and exemption from the Prescription Drug User Fee Act filing
fees. The Company is also in the process of applying for Orphan
Designation for CF treatment in Europe.
Cystic Fibrosis (CF)
fatal genetic disease that causes life-threatening lung infections and premature
death. It affects approximately 30,000 patients in the United States and nearly
70,000 worldwide. It is one of the most common genetic disorders in
the United States. To date, treatment of pulmonary conditions in CF
primarily includes antibiotics to address lung infection and airway clearance
therapies to break down and remove mucus. Despite advances in
research and medical therapies, the predicted median age of survival for
patients with CF in the United States is currently 37 years.
Laboratories, Inc. is a biotechnology company developing KL4 surfactant
therapies for respiratory diseases. Surfactants are produced naturally in
the lungs and are essential for breathing. Discovery Labs' novel
proprietary KL4 surfactant
technology produces a synthetic, peptide-containing surfactant that is
structurally similar to pulmonary surfactant and is being developed in liquid,
aerosol and lyophilized formulations. In addition, Discovery Labs'
proprietary capillary aerosolization technology produces a dense aerosol, with a
defined particle size that is capable of potentially delivering aerosolized
surfactant to the deep lung without the complications currently associated with
liquid surfactant administration. Discovery Labs believes that its
proprietary technology platform makes it possible, for the first time, to
develop a significant pipeline of surfactant products to address a variety of
respiratory diseases for which there frequently are few or no approved
therapies. For more information, please visit our website at www.Discoverylabs.com.
