Phase 1
Completed
Conditions
Pulmonary Arterial Hypertension
Interventions
Drug: Placebo and AIR001 Inhalation Solution (Expansion arm)
Registration Number

Dose level 1Sodium Nitrite Inhalation Solutiona single dose (5 mg sodium nitrite)of AIR001 Inhalation Solution administered by inhalation following nebulization
Expansion armPlacebo and AIR001 Inhalation Solution (Expansion arm)On Day 1, subjects will receive a single placebo-form dose of inhaled nebulized AIR001 Inhalation Solution (containing diluent and excipient solutions alone). On Day 2, the same subjects will receive a single administration of AIR001 Inhalation Solution at the minimum pharmacologically active and safe dose identified from dose levels 1-4. Subjects will be blinded to the treatment schema.
