Presentations highlighted the direct killing effect of NO on Mycobacterium abscessus (M. abscessus) and Pseudomonas aeruginosa (P. aeruginosa) as well as the use of the NO generator and delivery system as a potential therapy for M. abscessus complex (MABSC) lung infection
GARDEN CITY, N.Y., and REHOVOT, Israel, July 16, 2018 (GLOBE NEWSWIRE) -- AIT Therapeutics, Inc. (AITB), 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, today announced that in-vitro data, as well as data from its compassionate use study, were presented at the 3rd Annual World Bronchiectasis Conference held at Georgetown University in Washington, D.C. on July 12-14, 2018.
The first poster, entitled: “High-Dose Inhaled Nitric Oxide as a Potential Therapy Against Mycobacterium abscessus Lung Infection in Cystic Fibrosis,” shows an in vitro dose response for NO in the killing of M. abscessuss as a monotherapy in sputum. It also demonstrates differences in minimal bactericidal concentration of NO between various clinical strains of M. abscessus in vitro. The results also revealed the susceptibility of P. aeruginosa to NO is significantly greater with killing time less than half of what is seen with M. abscessus, and at a lower concentration.
The second poster, entitled: “Treatment of Refractory Mycobacterium abscessus Lung Infection with Inhaled Intermittent Nitric Oxide,” demonstrates inhaled NO dosed at 160 parts per million (ppm) for 30 minutes five times per day for 14 days and three times per day for 7 days provided clinical improvement on multiple parameters including 6-minute walk distance, FEV1 and quality-of-life parameters that persisted for up to 90 days post cessation of therapy. There was no effect on bacterial load. This patient had underlying cystic fibrosis and the MABSC had persisted for more than 8 years.
Both posters can be accessed on the company website at www.AIT-PHARM.com.
“Results from the treatment with our NO generator and delivery system were consistent with the results shown from our recently completed nine patient NTM study using cylinder gas,” said Steven Lisi, Chairman and Chief Executive Officer of AIT Therapeutics. “We continue to be on track to begin a pivotal study by the end of 2019 in nontuberculous mycobacteria (NTM) pending appropriate funding and anticipate this study will be conducted substantially in the home setting. Our in vitro data suggest that NO not only kills M. abscessus, but it more easily kills P. aeruginosa which is more prevalent and with well-established pathogenicity.”
Andrew Colin, M.D., Director, Division of Pediatric Pulmonology at the University of Miami, stated, “Confirmation of the killing effect of nitric oxide in-vitro on M. abscessus is uplifting. Add in the killing of Pseudomonas aeruginosa, a notoriously harmful pathogen in our CF population, and one can begin to have hope that NO may be the non-antibiotic anti-microbial we have been waiting for. The NTM community anxiously awaits the next step in the process with the NO generator and delivery system”.
About Mycobacterium abscessus complex (MABSC) of the Lungs
MABSC is the most aggressive and difficult to treat species of nontuberculous mycobacteria (NTM). There are currently no approved treatments for MABSC. Current standard-of-care is a cocktail of antibiotics that often proves to be ineffective with severe adverse effects. Most patients suffering from MABSC have an underlying disease, such as cystic fibrosis or chronic obstructive pulmonary disease (COPD). The median survival of those suffering from MABSC is less than 5 years.
About Nitric Oxide (NO)
Nitric Oxide (NO) is a powerful molecule proven to play a critical role in a broad array of biological functions. In the airways, NO is believed to play a key role in the innate immune system at concentrations of approximately 200 ppm. In vitro studies suggest that NO possesses anti-microbial activity not only against common bacteria, both gram-positive and gram-negative, but also against other diverse organisms including mycobacteria, fungi, yeast and parasites, and has the potential to eliminate multi-drug resistant strains.
About the 3rd Annual Bronchiectasis Conference
The Conference is a focused, cutting-edge gathering of the world’s experts on bronchiectasis and nontuberculous mycobacterial lung infections. Highlights of the conference include presentations of the most up to date research on disease mechanisms in bronchiectasis, including new understandings on the role of inflammation, infection and the microbiome. Clinical topics will include sessions on the diagnosis and treatment of bronchiectasis and NTM infections, including small group, case-based presentations specifically aimed at understanding the role of airway clearance, anti-inflammatory treatments and antibiotics.
