Key exclusion criteria
Medical Conditions

1. Persistent and clinically significant systemic hypertension or hypotension.
2. Interval history of newly developed left-sided heart disease.
3. Potentially life-threatening cardiac arrhythmia with an ongoing risk.
4. Uncontrolled bacterial, viral, or fungal infections which require systemic therapy.
5. Other severe acute or chronic medical or laboratory abnormality that may increase the risk associated with study participation or GB002 administration or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the subject inappropriate for entry into this study.
6. History of portopulmonary hypertension or portal hypertension due to cirrhosis classified as Child-Pugh Class A or higher.

10. Have any other condition or reason that, in the opinion of the Investigator and/or the Sponsor's Medical Monitor (or designee), would prohibit the subject from participating in the study.

Diagnostic Assessments
11. Chronic renal insufficiency
12. Hemoglobin (Hgb) concentration <8.5 g/dL.
13. Absolute neutrophil count (ANC) < 1x 10^9/L.
14. Platelet count <50 x 10^9/L.

Prior Therapy
15. Use of inhaled prostanoids.
