Carbon Monoxide Therapy for Severe Pulmonary Arterial Hypertension

NCT01523548 · Status: WITHDRAWN · Phase: PHASE1/PHASE2 · Type: INTERVENTIONAL

No results posted yet for this study

Summary

The purpose of this study is to examine the potential of carbon monoxide (CO) to decrease elevated blood pressure in the pulmonary artery. This symptom is seen in patients with pulmonary arterial hypertension, a rare disease that causes fatigue, dizziness, and shortness of breath because the blood vessels that supply the lungs narrow, forcing the heart to work harder to push blood through. Previous studies in the laboratory have shown that carbon monoxide has promise in treating these symptoms.

Subjects in this study are being asked to undergo a new type of treatment to improve pulmonary arterial hypertension by breathing CO gas. CO is a colorless, tasteless, odorless gas usually found in car exhaust or cigarette smoke. It is administered with a continuous flow of air. Subjects will undergo a screening process during which it will be determined if they are eligible for the study. After the screening process, if subjects meet eligibility criteria for the study, they will begin carbon monoxide treatment through a cushioned mask that is placed over the nose and mouth. This treatment will last for sixteen weeks.
