Study Overview
Brief Summary
This is an open label phase 2 pilot study designed to evaluate the safety, tolerability and device performance of the GeNO nitrosyl delivery system during right heart catheterization (RHC) in participants with pulmonary arterial hypertension (PAH). All participants will receive inhaled nitric oxide in oxygen or nitric oxide in air delivered by nasal cannula. Hemodynamics, clinical laboratory and clinical assessment data will be collected on all participants to evaluate safety.
Detailed Description
TREATMENT/FOLLOW-UP:
Participants meeting eligibility criteria will receive open label nitric oxide at 80 ppm via a nasal cannula. Hemodynamic clinical laboratory and clinical assessment data will be collected at baseline, after 15 minutes of inhaled nitric oxide administration, post RHC procedure and at hospital discharge. Day 5 +/- 3 post RHC, telephone contact to assess general health status.

- •Documented uncontrolled systemic hypertension as evidenced by systolic blood pressure greater than 160 mmHg or diastolic blood pressure greater than 100 mmHg.
- •Have used prescription appetite suppressants within 3 months prior to wean/transition.
- •Have chronic kidney disease stage IV or worse or the requirement for dialysis.
- •Be receiving an investigational drug, have in place an investigational device, or have participated in an investigational drug study within the past 30 days.
- •Have had an atrial septostomy.
- •Have anemia (hemoglobin <10 g/dL), active infection or any other ongoing condition that would interfere with the interpretation of study assessments.
- •Have any serious or life-threatening disease other than conditions associated with PAH (e.g. malignancy requiring aggressive chemotherapy, renal dialysis, etc.).
