Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an open-label, multicentre study evaluating the effect, safety and tolerability of the two regioisomers 1-(nitrosooxy)propan-2-ol and 2-(nitrosooxy)propan-1-ol (PDNO) infusion given to COVID-19 patients with acute pulmonary hypertension (aPH) and/or acute cor pulmonale (ACP).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Treatment with PDNO

Placebo treatment administered during the 120-minute observation period, followed by PDNO infusion. PDNO administered as an i.v. infusion of 5-15 minutes, respectively, for the increased planned dose titration steps: 3, 10 and thereafter steps of max 10 nmol/kg/min until the target effect on the mean pulmonary arterial pressure/pulmonary vascular resistance (MPAP/PVR) or a maximal dose of 120 nmol/kg/min is reached.

After 4 patients have been treated, the internal safety review committee (iSRC) will decide if the start dose will be increased. The new start dose could be in the interval 1 to 5 nmol/kg/min.

Group Type EXPERIMENTAL

Sodium chloride (placebo)

Intervention Type DRUG

Placebo (NaCl, commercially available dilution solution for parenteral use, 9 mg/mL)

PDNO

Intervention Type DRUG

PDNO consists of propylene glycol (1,2-propanediol, PD) chemically combined with NO (to be donated). The drug substance is formulated as an inherent mixture of 4 structure analogues. The mixture consists of an equilibrium of the 2 regioisomers 1-(nitrosooxy) propan-2-ol and 2-(nitrosooxy) propan-1-ol. In addition, each regioisomer is a racemic mixture.
