|Condition or disease||Intervention/treatment||Phase|
|Pulmonary Arterial Hypertension Idiopathic Pulmonary Fibrosis||Drug: Inhaled Nitric Oxide||Phase 2|
Up to 54 subjects undergoing RHC are planned in this study, and shall include subjects meeting eligibility criteria classified as WHO Group 1 PAH or WHO Group 3 IPF-PH. Subjects will receive inhaled nitric oxide from the GeNOsyl® System to characterize the hemodynamic response and evaluate safety and tolerability.
Dose cohorts of approximately 5, 15, and 20 ppm nitric oxide in air will be studied. Different dose levels will be achieved by varying the flow rate of the drug substance (80 ppm NO2 in balance air) delivered to the subject via nasal cannula. Each subject will receive two different doses of inhaled nitric oxide separated by a placebo (medical grade air or supplemental oxygen) washout. Eligible subjects will be assigned to a dosing cohort in an escalating manner to receive study drug (80 ppm nitric oxide in air.)

Experimental: Dosing Group 1
1 Liter per Minute (LPM)of inhaled nitric oxide via nasal cannula: approximately 5 parts per million (ppm)
Drug: Inhaled Nitric Oxide
Inhaled nitric oxide 80 ppm via nasal cannula at 1 LPM for 15 minutes followed by placebo washout of 15 minutes inhalation of medical grade air (or prescribed supplemental oxygen), and then inhaled nitric oxide 80 ppm via nasal cannula at 1 LPM
Other Name: GeNOsyl
Experimental: Dosing Group 2
2 LPM of inhaled nitric oxide via nasal cannula: approximately 15 ppm
Drug: Inhaled Nitric Oxide
Inhaled nitric oxide 80 ppm via nasal cannula at 1 LPM for 15 minutes followed by placebo washout of 15 minutes inhalation of medical grade air (or prescribed supplemental oxygen), and then inhaled nitric oxide 80 ppm via nasal cannula at 2 LPM
Other Name: GeNOsyl
Experimental: Dosing Group 3
4 LPM of inhaled nitric oxide via nasal cannula: approximately 20 ppm
Drug: Inhaled Nitric Oxide
Inhaled nitric oxide 80 ppm via nasal cannula at 1 LPM for 15 minutes followed by placebo washout of 15 minutes inhalation of medical grade air (or prescribed supplemental oxygen), and then inhaled nitric oxide 80 ppm via nasal cannula at 4 LPM
Other Name: GeNOsyl
- Identify the minimally and maximum effective doses of inhaled nitric oxide generated by the GeNOsyl® System compared to placebo. [ Time Frame: through end of Right Heart Catheterization procedure (Treatment Phase approximately 3 hours) ]
Assess mean change in pulmonary vascular resistance (PVR) for study drug dose 2 compared to placebo.
Assess change from pre-dose to end-of-hemodynamic assessment for study drug dose 1.
Assess change from placebo to end-of-hemodynamic assessment for study drug dose 2.
- Assess the safety and tolerability of nitric oxide generated by the GeNOsyl® System in subjects with WHO Group 1 PAH and WHO Group 3 PH-IPF. [ Time Frame: through end of study (approximately 30 days after treatment visit) ]
- Evaluate the pharmacokinetics of total nitrates/nitrites and methemoglobin produced following inhalation of nitric oxide via the GeNOsyl® System. [ Time Frame: up through 24 hrs after treatment period for subjects participating in PK sub-study ]Individual pharmacokinetic parameters for total nitrates/nitrites and methemoglobin will be summarized with descriptive characteristics.
