A Prospective, Open, Single-arm, Multi-center Phase IV Clinical Study of Inhaled Nitric Oxide Combined With Ventilatory Support for the Treatment of Neonatal (Gestational Age ≥34 Weeks) Hypoxic Respiratory Failure With Pulmonary Hypertension.
This is a prospective, open-label, single-arm, multicenter Phase IV clinical study to evaluate the safety of INOmax for the treatment of hypoxic respiratory failure with pulmonary hypertension in newborns (≥ 34 weeks gestational age). To evaluate the safety of INOmax combined with ventilatory support in the treatment of neonatal (≥ 34 weeks gestational age) hypoxic respiratory failure with pulmonary hypertension.
• Neonates ≥ 34 weeks gestation age.
• Hypoxic respiratory failure requiring more than 24 hours of ventilatory support.
• Clinical or echocardiographic evidence of pulmonary hypertension (systolic pulmonary arterial pressure \[sPAP\] \> 35 mm Hg or \> 2/3 systemic blood pressure \[SBP\] or there is a right-to-left shunt at the atrium or arterial ductus).
• Age less than 7 days at the time of treatment initiation with study drug.
• The neonatal guardian agrees to participate in the study and signs an informed consent form (ICF).
