Primary Outcome Measures:
  • Change in pulmonary arterial systolic pressure (PASP) from Baseline after treatment with iNO (measured by 2D transthoracic echocardiography with Doppler) [ Time Frame: baseline to end of treatment (1 day) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The secondary outcome is the occurrence of a decrease ≥ 5 mm Hg of partial pressure of oxygen in arterial blood (PaO2) from Baseline after treatment with iNO [ Time Frame: baseline to end of treatment (1 day) ] [ Designated as safety issue: No ]

Detailed Description:

This two-part study is designed to confirm the dose of inhaled nitric oxide (NO), administered through an investigational pulsed delivery device (INOpulse® DS-C) that results in decreased pulmonary arterial systolic pressure (PASP) without significantly affecting systemic oxygenation.

In Part A, 80 subjects will be randomized to 1of 4 treatment groups in a 1:1:1:1 ratio (with 20 subjects in each treatment group). Subjects assigned to an iNO group will receive pulsed iNO at a dose of 0.003 mg/kg IBW/hr, 0.010 mg/kg IBW/hr, or 0.015 mg/kg IBW/hr, with a set pulse width (PW) of 260 milliseconds (ms). Part A subjects assigned to the placebo group will receive nitrogen (N2) at a randomly assigned device setting of 0.003, 0.010 or 0.015 mg/kg IBW/hr with a set PW of 260 ms.

Subjects who were randomized in Part A are permitted to participate in Part B of the study. Subjects will need to be re-screened and re-randomized for Part B participation.

In Part B, 60 subjects will be randomized to 1 of 3 treatment groups in a 1:1:1 ratio (with 20 subjects in each treatment group). Subjects assigned to an iNO group will receive pulsed iNO at either 0.030 mg/kg IBW/hr or 0.075 mg/kg IBW/hr, with a set PW of 260 ms. Part B subjects assigned to placebo will receive N2 at a randomly assigned device setting of 0.030 mg/kg IBW/hr or 0.075 mg/kg IBW/hr with a set PW of 260 ms.

Part B will use a skewed block randomization scheme with 10 blocks of 6 subjects as follows:

  • Blocks 1-3: 3 subjects at 0.030 mg/kg IBW/hr, 1 subject at 0.075 mg/kg IBW/hr, and 2 subjects randomly assigned to placebo either 0.030 or 0.075 mg/kg IBW/hr
  • Blocks 4-7: 2 subjects at 0.030 mg/kg IBW/hr, 2 subjects at 0.075 mg/kg IBW/hr, and 2 subjects randomly assigned to placebo either 0.030 or 0.075 mg/kg IBW/hr
  • Blocks 8-10: 1 subject at 0.030 mg/kg IBW/hr, 3 subjects at 0.075 mg/kg IBW/hr, and 2 subjects randomly assigned to placebo either 0.030 or 0.075 mg/kg IBW/hr

  5. Receiving LTOT for ≥ 3 months and ≥ 10 hours per day as determined by history
  6. Echocardiogram with technical adequacy demonstrating tricuspid regurgitation velocity (TRV) ≥ 2.9 m/s at Screening, as determined by a blinded central echocardiography laboratory
  7. Females of childbearing potential must have a negative pre-treatment urine pregnancy test
  8. Signed informed consent prior to the initiation of any study mandated procedures or assessments

Exclusion criteria:

Subjects who meet any of the following criteria are not eligible for enrollment:

  1. Positive urine cotinine test
  2. Currently using, or having used within the past month, a nicotine patch
  3. A diagnosis of asthma or other non-COPD respiratory disease, in the opinion of the Investigator
  4. Lack of patency of nares upon physical examination
  5. Experienced an exacerbation requiring start of or increase in systemic oral corticosteroid therapy and/or hospitalization during the last month (ATS COPD Guidelines 2004)
  6. Left ventricular dysfunction as measured by:

    1. Screening echocardiographic evidence of left ventricular systolic dysfunction (left ventricular ejection fraction (LVEF) < 40%), or
    2. Screening echocardiographic evidence of left ventricular diastolic dysfunction > moderate (i.e., > Grade 2), or
    3. Any history of pulmonary capillary wedge pressure (PCWP), left atrial pressure (LAP) or left ventricular end diastolic pressure (LVEDP) > 18 mm Hg as measured during cardiac catheterization within the past 6 months unless documented to have resolved by a subsequent cardiac catheterization
  7. Clinically significant valvular heart disease that may contribute to PH, including mild or greater aortic valvular disease (aortic stenosis or regurgitation) and/or moderate or greater mitral valve disease (mitral stenosis or regurgitation), or status post mitral valve replacement
  8. Use within 30 days of screening or current use of approved PH medications such as sildenafil or bosentan (use of Cialis® or Viagra® for erectile dysfunction is permitted)
  9. Use of investigational drugs or devices within 30 days prior to enrollment into the study
  10. Any underlying medical or psychiatric condition that, in the opinion of the Investigator, makes the subject an unsuitable candidate for the study
