Brief Summary:
This is a placebo-controlled, double-blind, parallel, randomized, two-part, dose-confirming clinical study characterizing the pharmacodynamic effects of pulsed iNO using the combination product, inhaled nitric oxide/INOpulse DS-C vs. placebo in subjects with World Health Organization (WHO) Group 3 pulmonary hypertension (PH) associated with Chronic Obstructive Pulmonary Disease (COPD) on Long Term Oxygen Therapy (LTOT).

Condition or disease Intervention/treatment Phase
Pulmonary Hypertension Chronic Obstructive Pulmonary Disease Combination Product: Inhaled NO delivered via INOpulse DS-C Device Combination Product: Placebo delivered via INOpulse DS-C Device Phase 2

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
