What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Plasma pharmacokinetics (PK): Maximum observed plasma concentration (Cmax)	To determine the plasma Cmax of a single dose of HBI 3000 administered intravenously (IV), in the absence and the presence of CYP2D6 inhibition, achieved with multiple oral doses of paroxetine, a strong CYP2D6 inhibitor, in healthy male and female subjects. Blood samples will be taken from 0 through 72 hours after the start of HBI-3000 infusion.	72 hours
Plasma pharmacokinetics (PK): Area Under the Curve (AUC) from time 0 to last measurable concentration (AUC0 - tau)	To determine the plasma AUC of a single dose of HBI 3000 administered intravenously (IV), in the absence and the presence of CYP2D6 inhibition, achieved with multiple oral doses of paroxetine, a strong CYP2D6 inhibitor, in healthy male and female subjects. Blood samples will be taken from 0 through 72 hours after the start of HBI-3000 infusion.	72 hours
Plasma pharmacokinetics (PK): Area Under the Curve (AUC) from time 0 to infinity (AUC0 - infinity), if data permits	To determine the plasma AUC of a single dose of HBI 3000 administered intravenously (IV), in the absence and the presence of CYP2D6 inhibition, achieved with multiple oral doses of paroxetine, a strong CYP2D6 inhibitor, in healthy male and female subjects. Blood samples will be taken from 0 through 72 hours after the start of HBI-3000 infusion.	72 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Treatment-Emergent Adverse Events (TEAEs), including serious TEAEs	To evaluate the safety and tolerability of HBI-3000 in the absence and the presence of paroxetine, as measured by Treatment-Emergent Adverse Events (TEAEs), including serious TEAEs. TEAE is defined as follows: An AE that emerges during treatment, having been absent at pretreatment (Baseline), an AE that re emerges during treatment, having been present at pretreatment (Baseline) but stopped before treatment, or an AE that worsens in severity during treatment relative to the pretreatment state, when the AE is ongoing. TEAEs will be recorded for approximately 25 days commencing with the start of HBI-3000 infusion.	25 days

12-lead ECG	To evaluate the safety and tolerability of HBI-3000 in the absence and the presence of paroxetine, as measured by 12-lead ECG. Twelve-lead ECGs will be measured at Screening and periodically during the study using standardized equipment provided by the core ECG laboratory and reviewed locally by the Investigator. QTc interval will be calculated from Fridericia's formula.	25 days
Continuous telemetry	To evaluate the safety and tolerability of HBI-3000 in the absence and the presence of paroxetine, as measured by monitoring via a continuous cardiac telemetry monitoring system for 8 hours commencing with the start of HBI-3000 infusion	8 hours beginning at the start of infusion
Infusion site (local) reactions	To evaluate the safety and tolerability of HBI-3000 in the absence and the presence of paroxetine, as measured by observing infusion site (local) reactions for the duration of the study (approximately 25 days) commencing with the start of HBI-3000 infusion	25 days
Physical examination findings	To evaluate the safety and tolerability of HBI-3000 in the absence and the presence of paroxetine, as measured by examination of body systems and symptom directed examination as indicated, at Screening and during the study (approximately 25 days)	25 days
Left ventricular ejection fraction (LVEF), Exploratory	To evaluate the safety and tolerability of HBI-3000 in the absence of paroxetine, as measured by 2D transthoracic echocardiogram to measure changes in cardiac contractility, determined at baseline and at 30 minutes and 2 hours after the start of infusion	At baseline and 2 hours beginning at the start of infusion
