Design outcomes

Primary

MeasureTime frame
Main Objective: To determine the ratio of parent drug to metabolites in the circulation. Profiling of [14C]-etripamil metabolites in blood, urine and feces. To determine the mass balance of drug-related materials following intranasal administration. To determine the primary route of excretion of drug-related materials. To determine the total radioactivity versus time profile in plasma and whole blood. ;Secondary Objective: To evaluate the safety and tolerability of [14C]-etripamil after a single intranasal dose. To determine the pharmacokinetics (PK) in plasma and urine after a single dose of [14C]-etripamil nasal spray to healthy male subjects. ;Primary end point(s): Whole blood: Maximum observed total radioactivity (Cmax). Time from time zero to peak total radioactivity (tmax). Area under the total radioactivity-time curve from time zero to the last measurable concentration (AUC0-t). Area under the total radioactivity-time curve from time zero to infinity (AUC0-inf). Plasma: Maximum observed total radioactivity (Cmax). Time from time zero to peak total radioactivity (tmax). Area under the total radioactivity-time curve from time zero to the last measurable concentration of total radioactivity (AUC0-t). Area under the total radioactivity-time curve from time zero to infinity (AUC0-inf). Total radioactivity half-life (t1/2). Total radioactivity clearance (CL/F) and volume of distribution (Vz/F). [14C]-metabolic profile and identification of metabolites in plasma and/or blood. Urine: Total radioactivity amount excreted in urine (Aeu). Total radioactivity excreted in urine as a percentage of the radioactive dose. [14C]-metabolic profile and identification of metabolites in urine. Major radioactive peak/metabolite(s) in the urine radiochromatogram(s) as a percentage of the radioactive dose. Feces: Total radioactivity amount excreted in feces (Aef). Total radioactivity percentage dose excreted. [14C]-metabolic profile and identification of metabolites in feces. Majo

Secondary

MeasureTime frame
Secondary end point(s): The following are defined as safety/tolerability parameters: Adverse events (AEs); Vital signs (blood pressure, pulse rate, temporal temperature); 12-lead ECG; Telemetry; Clinical laboratory parameters; Physical examination. The following PK parameters will be calculated for etripamil (MSP-2017) and its main inactive metabolite MSP-2030, whenever possible and appropriate: Plasma: Maximum observed etripamil concentration (Cmax). Time from time zero to peak etripamil concentration (tmax). Area under the etripamil concentration-time curve from time zero to the last measurable concentration (AUC0-t). Area under the etripamil concentration-time curve from time zero to infinity (AUC0-inf). Etripamil half-life (t1/2). Etripamil clearance (CL/F) and volume of distribution (Vz/F). Urine: Amount excreted unchanged in urine (Aeu). Amount excreted unchanged in urine over a given time interval (Aeu,0-t). Fraction of dose excreted in urine (etripamil only) (fe/F). Renal clearance, calculated as Aeu,0-t/AUC0-t (CLr). ;Timepoint(s) of evaluation of this end point: during the study
