Beyond Air® Reports Positive Long-Term Safety Data for High Concentration Inhaled Nitric Oxide in Bronchiolitis at the Pediatric Academic Societies Meeting 2022

April 25, 2022 | 4:05 pm EST

GARDEN CITY, N.Y., April 25, 2022 — Beyond Air, Inc. (NASDAQ: XAIR), a clinical-stage medical device and biopharmaceutical company focused on developing inhaled nitric oxide (NO) for the treatment of patients with respiratory conditions, including serious lung infections and pulmonary hypertension and, through its affiliate Beyond Cancer, ultra-high concentration nitric oxide (UNO) for the treatment of solid tumors, today announced positive long-term safety data for high concentration inhaled NO for the treatment of bronchiolitis. These data were included in an oral presentation at the Pediatric Academic Societies 2022 Meeting (PAS 2022), which is being held April 21-25 in Denver, Colorado.

The multi-center study for longitudinal data collection was designed to evaluate the long-term effect of inhaled NO treatment in infants who participated in three pilot studies conducted between 2012-2020. These three randomized, double blind clinical trials were conducted with intermittent high dose inhaled NO of 85-160 ppm for acute bronchiolitis or oxygen/air (control), administered in addition to standard supportive treatment (SST). A total of 198 infants participated in the three studies, with 101 infants participating in the long-term follow-up study. Previously announced data from all three of these studies showed a favorable short term safety profile as well as strong trends for efficacy. No inhaled NO-treatment related serious adverse events (SAEs) or severe AEs were reported, and the incidence level for severe AEs was similar among all groups. Study endpoints for the long-term safety study included percentage of subjects re-hospitalized for bronchiolitis related reasons, such reasons included wheezing episodes, pneumonia, asthma, etc., and the percentage of subjects re-hospitalized for any reason.

Data from the study, presented in the tables below, show the re-hospitalization rate per 100 Patient Exposure Years (PEY) due to bronchiolitis related reasons trended favorably for the inhaled NO group. In addition, the long-term subject re-hospitalization rate for any reason was similar between inhaled NO and control groups. As such, the study concludes that the treatment of hospitalized infants with acute bronchiolitis by intermittent high dose inhaled NO show a favorable long-term safety profile.

“We are pleased to announce new long-term safety data which further support the development of nitric oxide as a therapy for bronchiolitis or similar acute treatment settings, such as community-acquired viral pneumonia (CAVP). A proposed pivotal study of high concentration inhaled NO to treat bronchiolitis or CAVP using our LungFit® Pro system is expected to begin in the fourth quarter of 2023,” said Steve Lisi, Chairman and Chief Executive Officer of Beyond Air. “The Beyond Air team continues to execute in this challenging pandemic environment and move the Beyond Air pipeline forward.”

“These long-term data confirm the positive safety profile of treating acutely with high concentration NO and a larger, confirmatory efficacy study is warranted in this patient population as soon as possible, as this is an area of immediate medical need,” stated Aviv Goldbart, M.D. Professor, Head of Department Pediatrics, Soroka University Medical Center; Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel.

Dr. Goldbart presented the results of the long-term study at the PAS 2022 Meeting in an oral presentation titled, “1179165 – Long-term effects of inhaled nitric oxide in infants with bronchiolitis – a multi center study”. The presentation is available on the Events page of the Beyond Air website (click here).

About Beyond Air, Inc.
Beyond Air, Inc. is a clinical-stage medical device and biopharmaceutical company developing a revolutionary NO Generator and Delivery System, LungFit®, that uses NO generated from ambient air to deliver precise amounts of NO to the lungs for the potential treatment of a variety of pulmonary diseases. The LungFit® can generate up to 400 ppm of NO, for delivery either continuously or for a fixed amount of time and has the ability to either titrate dose on demand or maintain a constant dose. The Company is currently applying its therapeutic expertise to develop treatments for pulmonary hypertension in various settings, in addition to treatments for respiratory tract infections that are not effectively addressed with current standards of care. Beyond Air is currently advancing its revolutionary LungFit® for clinical trials for the treatment of severe lung infections such as acute viral pneumonia (including COVID-19) and nontuberculous mycobacteria (NTM). Additionally, Beyond Air is using ultra-high concentrations of NO with a proprietary delivery system to target certain solid tumors in the pre-clinical setting. For more information, visit

About Nitric Oxide (NO)
Nitric Oxide (NO) is a powerful molecule, naturally synthesized in the human body, proven to play a critical role in a broad array of biological functions. In the airways, NO targets the vascular smooth muscle cells that surround the small resistance arteries in the lungs. Currently, exogenous inhaled NO is used in adult respiratory distress syndrome, post certain cardiac surgeries, and persistent pulmonary hypertension of the newborn to treat hypoxemia. Additionally, NO is believed to play a key role in the innate immune system and in vitro studies suggest that NO possesses anti-microbial activity not only against common bacteria, including both gram-positive and gram-negative, but also against other diverse pathogens, including mycobacteria, viruses, fungi, yeast, and parasites, and has the potential to eliminate multi-drug resistant strains.

About the LungFit®*
Beyond Air’s LungFit® is a cylinder-free, phasic flow nitric oxide generator and delivery system and has been designated as a medical device by the U.S. Food and Drug Administration (FDA). The ventilator compatible version of the device can generate NO from ambient air on demand for delivery to the lungs at concentrations ranging from 1 part per million (ppm) to 80 ppm. The LungFit® system could potentially replace large, high-pressure NO cylinders providing significant advantages in the hospital setting, including greatly reducing inventory and storage requirements, improving overall safety with the elimination of NO2 purging steps, and other benefits. The LungFit® can also deliver NO at concentrations at or above 80 ppm for potentially treating severe acute lung infections in the hospital setting (e.g. COVID-19, bronchiolitis) and chronic, refractory lung infections in the home setting (e.g. NTM). With the elimination of cylinders, Beyond Air intends to offer NO treatment in the home setting.

* Beyond Air’s LungFit® is not approved for commercial use. Beyond Air’s LungFit® is for investigational use only. Beyond Air is not suggesting NO use over 80 ppm or use at home.

About Bronchiolitis
The majority of hospital admissions of infants with bronchiolitis are caused by respiratory syncytial virus (RSV). RSV is a common and highly transmissible virus that infects the respiratory tract of most children before their second birthday. While most infants with RSV present with minor respiratory symptoms, a small percentage develop serious lower airway infections, termed bronchiolitis, which can become life-threatening. The absence of treatment options for bronchiolitis limits the care of these sick infants to largely supportive measures. Beyond Air’s system is designed to effectively deliver 150 – 400 ppm NO, for which preliminary studies indicate may eliminate bacteria, viruses, fungi, and other microbes from the lungs.
