Bronchopulmonary dysplasia is a condition that affects preterm infants, especially those born with underdeveloped lungs who require prolonged oxygen therapy or mechanical ventilation to help them breathe after birth. It is characterized by damage and abnormal development of the lung tissue and airways, often resulting from life-saving interventions necessary for babies born very prematurely. Airway Therapeutics is developing a new class of biologics for respiratory and inflammatory diseases, starting with bronchopulmonary dysplasia. We spoke to Marc Salzberg, CEO of Airway Therapeutics, about the company’s experimental therapy zelpultide alfa, why it’s a pipeline in a product, and its development path forward.
