4. Weight at birth ≥ 2,000 g.

5. Idiopathic PPHN or PPHN due to parenchymal lung disease

6. Documented diagnosis of pulmonary hypertension (PH) confirmed by echocardiography.

7. Need for continued inhaled nitric oxide (iNO) at a dose > 10ppm after at least 4 hours of continuous iNO treatment.

8. Two oxygenation index (OI) values ≥ 12 taken at least 30 minutes apart, in the 12 hours prior to randomization and while the patient is receiving iNO treatment.

10. Hepatic failure or all conditions with alanine aminotransferase (ALT) values > 2 x upper limit of normal (ULN).

11. Renal function impairment such as serum creatinine > 3 x ULN or anuria.

12. Known intracranial hemorrhage grade III or IV.

13. Either hemoglobin or hematocrit level < 75% of the lower limit of normal (LLN).
