WARRINGTON, Pa., April 29, 2020 /PRNewswire/ -- Windtree Therapeutics, Inc. (OTCQB: WINTD), a biotechnology and medical device company focused on developing drug product candidates and medical device technologies to address acute cardiovascular and pulmonary diseases, today announced it has enrolled the first patient into its AEROSURF® phase 2b bridging study in premature infants with respiratory distress syndrome (RDS). This bridging study is intended to complete the phase 2 clinical program for AEROSURF and transition clinical development to phase 3 by validating the performance of the new aerosol delivery system (ADS) in the neonatal intensive care unit (NICU) and a more intensive dosing regimen.
"Enrollment of the first patient in our phase 2b bridging study is an important step to build upon the positive results observed in the three previous AEROSURF phase 2 clinical trials," said Craig Fraser, Chief Executive Officer of Windtree. "If successful, this bridging study will validate our new ADS technology and transition the program to phase 3 clinical development. We believe AEROSURF represents a significant medical advancement in neonatology and look forward to the results from this bridging study."
Steve Simonson, M.D., Chief Medical Officer of Windtree added, "The current standard of care for administration of surfactant therapy is via an invasive process through a tube placed in the trachea. The trend in neonatology has been to use non-invasive respiratory support such as nasal continuous positive airway pressure (nCPAP) to treat RDS, but this method precludes the administration of surfactant therapy in a timely manner. AEROSURF allows for non-invasive delivery of aerosolized KL4 surfactant to premature infants receiving nCPAP." Dr. Simonson continued, "Data from our previous trials suggest that AEROSURF may reduce the incidence of nCPAP failure and the need for invasive intubation and delayed surfactant therapy."
About the AEROSURF Bridging Study
The AEROSURF phase 2b bridging study is a multicenter, randomized, controlled study with masked treatment assignment in up to 90 premature infants 26 to 32 weeks gestational age (GA) receiving nCPAP for RDS. The trial will leverage the favorable safety profile from the previous phase 2 studies to evaluate higher and more frequent dosing of aerosolized KL4 surfactant compared to premature infants receiving standard care of nCPAP alone. The trial will utilize the new ADS technology and bridge to data generated in the phase 2 program utilizing a prototype device on the following endpoints: time to nCPAP failure (the need for intubation and delayed surfactant therapy), incidence of nCPAP failure and physiological parameters indicating the effectiveness of lung function.
AEROSURF® (lucinactant for inhalation) is an investigational combination drug/medical device product that we are developing to improve the management of RDS in premature infants who may not have fully-developed natural lung surfactant and may require surfactant therapy to sustain life. AEROSURF is designed to deliver aerosolized KL4 surfactant noninvasively using our proprietary ADS technology and potentially may meaningfully reduce the use of invasive endotracheal intubation and mechanical ventilation. We believe that AEROSURF, if approved, may meaningfully reduce the number of premature infants who are subjected to invasive surfactant administration, and potentially provide transformative clinical and pharmacoeconomic benefits. The FDA has granted Fast Track designation for AEROSURF to treat RDS.
