More Information


The purpose of this study is to test if an investigational drug, Sodium Nitrite Solution (AIR-001) inhaled through a nebulizer (a hand held breathing device), is safe and can improve the ability to tolerate all forms of physical activity, including exercise, and thus improve quality of life in people who have chronic diastolic heart failure. "Investigational" means that the study drug is currently being tested in research studies and is not approved by the US Food and Drug Administration (FDA) for standard medical use to treat heart failure.
