Bronchiolitis

A Leading Cause of Global Child Mortality

Bronchiolitis is an infection of the small airways. It is also the most common manifestation of acute lower respiratory infection (ALRI) in early infancy, and is the leading cause of global child mortality. Viral bronchiolitis is currently the most common reason for pediatric hospital admission in the US, accounting for almost 20% of all-cause infant hospitalizations. Viral etiology is the main cause, and among the respiratory viruses, respiratory syncytial virus (RSV) is believed to be the most important viral pathogen causing ALRI in young children.

Worldwide, it is estimated that 60,000 to 199,000 children younger than 5 years die yearly from RSV-associated ALRI, with 99% of these deaths occurring in developing countries. The disease is common mainly in the first year of life. The clinical signs and symptoms are consistent with hypoxia, difficulty breathing, coryza, poor feeding, cough, wheeze and crepitations on auscultation, and in some cases respiratory failure.

Tremendous Opportunity for Patient Care

There are no drugs approved for the treatment of bronchiolitis¹. The standard of care in the hospital is oxygen and hydration.

Beyond Air’s goal is to reduce the duration of bronchiolitis symptoms in infants and the length of hospitalization. Elderly population trials will follow that of infants.

Clinical Development

We have completed two double-blind, randomized, single-center, 2-arm studies. The primary objectives were to study the safety and tolerability of 160 ppm nitric oxide intermittent inhalation treatment in 2- to 12-month old subjects admitted to hospital and diagnosed with acute bronchiolitis. The planned secondary objectives were to assess the efficacy of NO intermittent inhalation treatment (in addition to standard O₂ treatment) compared to standard O₂ treatment alone, assessed as the LOS, clinical score improvement, and length of standard O₂ treatment.
