Abstract
Background ENA-001 (formerly known as GAL-021) is a novel, first-in-class respiratory stimulant. Pharmacokinetic and pharmacodynamic properties, plus safety and tolerability, were assessed in a randomized, single-center study of healthy volunteers. Methodology This four-period study was designed to test continuous two-hour intravenous infusion regimens of ENA-001 at doses of 0.96, 1.44, and 1.92 mg/kg/hour versus placebo. Each participant received four infusions with a seven-day minimum washout between them: one infusion each of the three doses of ENA-001 and one placebo. Pharmacokinetic and pharmacodynamic parameters were assessed and adverse events were recorded. Results A total of 17 participants completed the study. ENA-001 was generally safe and well tolerated over the dose range studied (0.96 to 1.92 mg/kg/hour). ENA-001 was able to drive hyperventilation in a dose-dependent manner in healthy participants. Increases in ventilation due to ENA-001 were not associated with like-magnitude blood pressure response. ENA-001-stimulated decreases in ETCO2 were associated with small, statistically significant, increases in SpO2 levels. Hyperventilation occurred in two participants at the highest dose level, leading to study discontinuation. The terminal half-life of ENA-001 was 6.33 hours. Conclusions The respiratory stimulant ENA-001 demonstrated well-behaved pharmacokinetics following the two-hour infusion. Mean peak plasma concentrations and the mean total systemic exposure values were approximately dose-proportional in the dose range studied.
