Discovery Labs Reports Preliminary Results From Phase 2 Clinical Trial of Surfaxin in Pediatric Acute Respiratory Failure
WARRINGTON, Pa., Jun 9, 2010 (GlobeNewswire via COMTEX) -- Discovery Laboratories, Inc. reports preliminary results from its Phase 2 clinical trial of Surfaxin(R) in children with Acute Respiratory Failure (ARF), a critical condition often caused in children by severe respiratory infections. The objective of the study was to evaluate the safety and tolerability of intratracheal administration of Surfaxin and to assess whether Surfaxin treatment could decrease the duration of mechanical ventilation in children with ARF.
The Phase 2 trial was a multicenter, randomized, masked, placebo-controlled estimation trial that enrolled 165 children under the age of two with ARF and compared Surfaxin treatment to standard of care alone, masked with sham air control. All children enrolled received standard of care and were randomized to receive either Surfaxin at 5.8 mL/kg of body weight or sham air. The trial enrolled patients at 24 sites located in the northern and southern hemispheres.
Key preliminary observations in this Phase 2 trial are:
-- Relative to the control treatment group, Surfaxin treatment reduced time
on mechanical ventilation by approximately 10%, although this
observation was not statistically significantly different. Duration on
mechanical ventilation was 3.8 days for the Surfaxin treatment group
versus 4.1 days for the control treatment group, expressed as the
geometric mean (primary analysis per protocol).
-- Surfaxin treatment appeared generally safe and well tolerated in this
trial. Statistically significant differences in the incidence of
bradycardia and desaturation were observed in the Surfaxin treatment
group during the dosing period versus the control treatment group.
Generally, such peri-dosing events are transient and expected with
intratracheal surfactant administration.
Comprehensive analysis of the data from this trial is ongoing. Further assessment of safety and tolerability, as well as in-depth analysis of additional efficacy endpoints and patient sub-populations, is expected to be completed in the third quarter of 2010. Following this analysis, Discovery Labs in collaboration with the ARF Steering Committee plans to present the comprehensive results at relevant medical congresses and submit these data for publication in a peer review journal.
Robert Segal, MD, Chief Medical Officer and Senior Vice President of Discovery Labs, commented, "Pediatric Acute Respiratory Failure represents a significant medical challenge and, unfortunately, there are no approved medical therapies that effectively treat this disorder today. Pulmonary surfactant is critical for normal respiration and may become impaired following patient exposure to a pathogen such as influenza or respiratory syncytial virus. The comprehensive data set from this Phase 2 trial is being further analyzed with the study Steering Committee as we evaluate next steps. These data are important as we are assessing, for the first time, the safety, tolerability and efficacy of intratracheally administered Surfaxin in the ARF patient population."
Surfaxin is an investigational drug candidate that has not been approved by the FDA or any other world health regulatory authority.
About Acute Respiratory Failure
ARF in young children occurs primarily after they have been exposed to serious respiratory infections, such as influenza (including the type A serotype referred to as H1N1) or respiratory syncytial virus (RSV), and leads to an impairment in lung function and the need for endotracheal intubation and mechanical ventilation (the current standard of care). Children with ARF usually suffer surfactant inactivation as part of the disease process. When there is insufficient functional surfactant in the lung, the alveoli (air sacs) collapse and are unable to support sufficient oxygenation. ARF affects approximately 15,000 children under two years of age in the United States with an estimated 30,000 - 40,000 children afflicted in developed countries each year, depending on severity of the viral season. Presently there are no approved drugs for the treatment of ARF.
About Discovery Labs
Discovery 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 or 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 KL4 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.
