Total lung capacity (TLC) or FVC ≥ 70% predicted~Exclusion Criteria:~1. Evidence of chronic thromboembolic disease or acute pulmonary embolism as assessed by ventilation-perfusion (V/Q) scan, computed tomography (CT)-angiogram, or pulmonary angiogram prior to screening.~2. Uncontrolled systemic hypertension as evidenced by sitting systolic blood pressure \> 160 mm Hg or sitting diastolic blood pressure \> 100 mm Hg during screening visit after a period of rest.~3. Systolic blood pressure \< 90 mm Hg during screening and baseline visits.~4. WHO Pulmonary Hypertension Group 2-5.~5. Human immunodeficiency virus (HIV)-associated PAH.~6. History of left-sided heart disease and/or clinically significant cardiac disease.~7. Untreated severe obstructive sleep apnea.~8. History of atrial septostomy within 180 days prior to screening.~9. Pulmonary venous occlusive disease (PVOD).~10. Subjects with a history of portopulmonary hypertension or portal hypertension due to cirrhosis classified as Child-Pugh Class A or higher; or baseline ALT or AST \> 2 x ULN or Total Bilirubin ≥ 2 x ULN.~11. History of malignancy within 5 years prior to screening.~12. History of a potentially life-threatening cardiac arrhythmia with an ongoing risk.~13. Severe acute or chronic medical or laboratory abnormality that may increase the risk associated with study participation or IP administration (eg; history intracranial hemorrhage).~14. Chronic renal insufficiency as defined by an estimated glomerular filtration rate (eGFR) \< 45 mL/min/1.73m2 via Chronic Kidney Disease Epidemiology Collaboration (CKD-epi) at screening or requires dialytic therapy or hemofiltration.~15. Hemoglobin (Hgb) concentration \< 8.5 g/dL at screening.~16. Evidence of active HIV, Hepatitis B or Hepatitis C, or tuberculosis (TB) infections.~17. Inhaled prostanoids; these drugs may be withdrawn ≥ 4 weeks prior to or at screening, if clinically indicated.~18. Use of oral anticoagulants (ie, warfarin or NOAC) at randomization.~19. Requirement of intravenous (IV) inotropes (ie, levosimendan, dopamine, dobutamine, milrinone, norepinephrine) other than an IV prostanoid within 4 weeks of screening.~20. Prior participation in GB002 studies and/or prior treatment with GB002.~21. Currently participating in or has participated in a study of an investigational agent or has used an investigational device for the treatment of PAH within 4 weeks prior to screening.~22. Current use of inhaled tobacco and/or inhaled marijuana.~23. Current alcohol use disorder as defined by DSM-5 and/or positive test for drugs of abuse (amphetamines, methamphetamines, cocaine, phencyclidine \[PCP\]).~24. Subjects with a history of severe milk protein allergy. In addition, subjects with known intolerance or hypersensitivity to lactose who, in the opinion of the investigator, may experience severe symptoms following the ingestion of lactose.~25. QTcF of \> 480 msec recorded on a screening or baseline ECG or receiving concurrent treatment with medications that prolong QT interval.~26. Have any other condition or reason that, in the opinion of the Investigator or Medical Monitor, would prohibit the subject from participating in the study.~NOTE: Additional inclusion/exclusion criteria may apply, per protocol.
