Pulmonary (Arterial) Hypertension Study

Trial Objective

The study looks to identify the minimal and maximum effective dose of inhaled nitric oxide using an investigational drug/device combination product, the GeNO NITROsyl™ System, when compared to placebo (air).
Pulmonary hypertension (PH) refers to a condition in which high blood pressure exists within the vessels of the lungs. Pulmonary arterial hypertension (PAH) is one of five types of PH in which the pressure in the arteries of the lungs becomes extremely high; this high blood pressure then puts a strain on the heart.

This study is 60 days in duration (1 day for right heart catheterization and a follow up phone call 30 days later) and includes diagnostic cardiac testing, electrocardiogram and echocardiogram procedures.


This trial is active and currently recruiting.
