Summary

This is a first-in-human, single-blind, placebo-controlled, single-centre study designed to assess the safety and tolerability of PDNO in healthy male and female subjects. In addition, the exposure of 1,2 propanediol (PD) will be evaluated.

There are 2 parts to the study:

Part I: single ascending dose (SAD), 7 cohorts, 30 minutes intravenous (i.v.) infusion of placebo followed by 1-hour i.v. infusion of PDNO to assess safety, tolerability and PD exposure in healthy male and female subjects.

Part II: ascending doses of PDNO in 2 cohorts, 30 minutes i.v. infusion of placebo followed by 3 ascending doses of PDNO in cohort 1 and 3 ascending doses of PDNO in cohort 2. The first 2 doses in each cohort will be i.v. infused for 30 minutes whereas the last will be i.v. infused for 3 hours to assess safety, tolerability and PD exposure in healthy male and female subjects.

If indicated by emerging data and recommended by the internal safety review committee (iSRC), 2 additional dose groups/cohorts (4+4 subjects) may be added to Part I and 1 dose group/cohort (4 subjects) may be added to Part II.

Interventions

DRUG

PDNO

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.

DRUG

Sodium chloride (placebo)

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