The purpose of this study is to evaluate the efficacy and safety of open-label exposure of
gNO in patients with NTM lung disease. Subjects will receive the study drug by inhaling
through a nasal mask. Subjects will be treated for 3 weeks (5 days per week) and followed
monthly for 3 months.


Inclusion Criteria:

Subjects are >18 years of age and able to provide informed consent.

Subjects have NTM lung disease as defined by each of the following:

Sputum cultures positive for NTM (MAC or M abscessus) Radiologic studies that demonstrate
features consistent with disease such as nodular bronchiectasis and/or cavities Symptoms
consistent with disease including respiratory (e.g. cough, sputum production, hemoptysis,
chest pain) and constitutional (e.g. fevers, night sweats, fatigue, myalgias, arthralgias,
weight loss) Subjects are able to produce sputum for culture (either spontaneous or
induced).

Subjects have a history of persistently positive sputum cultures for NTM defined as >4
number of cultures over 24 months with >75% positive AND a positive culture in the last 3
months.

Clinically stable with no significant changes in health status within 14 days prior to
Screening or Day 1 Subjects are willing and able to perform requirements of the study.

Exclusion Criteria:

Smoking history in the prior 6 months Significant hemoptysis within 30 days prior to
screening (>5 ml of blood in one coughing episode or >30 ml of blood in a 24 hour period)
Forced expiratory volume at one second (FEV1) <40% of predicted On supplemental oxygen or
SaO2 <90% at screening or Day 1, or within 30 days prior to enrollment.

Known cardiac (left heart) insufficiency (defined as LVEF <35%) prior to screening Known
pulmonary hypertension Known or suspected hemoglobinopathy Initiation of NTM treatment
regimen or a change in the regimen was made in the prior 6 months. Subjects on active
treatment can be enrolled if they have been on a stable anti-NTM regimen for at least 6
months.

Initiation of new chronic therapy within 4 weeks prior to screening Use of drugs known to
increase methemoglobin (see 12.2.7) at screening

Any of the following abnormal lab values at screening:

6-GPD deficiency Hemoglobin <10g/dl Platelet count <100,000/mm3 Prothrombin time
international ratio (INR) >1.5 Abnormal liver function defined as any two of the following
ALT >3x ULN AST >3x ULN ALP >3x ULN GGT >3x ULN

Abnormal renal function defined as:

Calculated Creatinine Clearance <50 ml (as calculated by Cockcroft/Gault)

For women of child bearing potential:

Positive pregnancy test at screening or Lactating or Unwilling to practice a medically
acceptable form of contraception from screening to Day 15 (acceptable forms of
contraception: abstinence, hormonal birth control, intrauterine device, or barrier method
plus a spermicidal agent) Use of an investigational drug within 30 days prior to screening
Intravenous or oral steroids (>10 mg/d prednisone equivalent) in the 14 days prior to
screening Any condition that the Investigator believes would interfere with the intent of
this study or would make participation not in the best interest of the subject.
