Prolonged-Use of Inhaled Gaseous Nitric Oxide for Adult With Non-Tuberculous Mycobacteria Infection
Nitric Oxide gas at 160ppm · Phase 2
About this trial
An open labeled Study (NCT03331445) is demonstrating encouraging safety and efficacy results for most subjects receiving 160ppm nitric oxide gas (gNO) for treatment of non-tuberculous mycobacteria (NTM) over a 15 day treatment regimen. In one subject, who had a reduction in sputum culture concentration of Bacterium bolletii from plus 3 to plus 1 corresponding to a 2-3 log10 cfu/gm reduction during the treatment, the one-week post treatment follow-up sputum culture had increased to plus 2. It is hypothesized that a longer treatment period may be necessary to fully eradicate NTM from the sputum culture in chronic lung disease. This study will extend the period of gNO exposure for a prolonged period of time (3 months) to attempt to fully eradicate the NTM in this single subject. This study will transition from the medical clinic to supervised delivery in the patient's home environment.
