|Condition or disease||Intervention/treatment||Phase|
|Non-Tuberculous Mycobacterial Pneumonia||Drug: Nitric Oxide 0.5 % / Nitrogen 99.5 % Gas for Inhalation||Phase 2|
Primary Objective: Assess the safety of inhaled NO (gNO) in adults with NTM
Safety will be evaluated by unanticipated adverse events in clinical labs (hematology, coagulation, and serum chemistries); in vitals; in inspired concentration of NO, O2 and NO2 delivered to each subject and; in real time methemoglobin and oxygen saturation levels.
Determine the safety of gNO in the NTM population, • as confirmed by no unanticipated adverse events
Secondary safety Endpoint: Determine the efficacy of inhaled NO in adults with NTM.
Efficacy will be evaluated by measuring the change in lung function with spirometry (specifically absolute change in FEV1 % predicted) from baseline to Days 5, 12, 19 and 26 during and after treatment. Because deterioration of lung function is the primary cause of death in patients with NTM, absolute change in FEV1 % predicted has been used to evaluate the clinical efficacy.
Secondary Efficacy Endpoint Determine the presence of an efficacy signal of gNO in the NTM population,
Efficacy will be assessed by the antimicrobial effect of inhaled NO on the density of NTM species and other microorganisms in sputum. Serial measurements of these microbial colony counts in sputum have been previously used as a measure of antimicrobial activity in other clinical trials of antibiotics in NTM.
• as confirmed by an improvement in pre-treatment bacterial colonization and post-treatment bacterial colonization on Day 5, 12, 19 and 26.
