Clinical Trial Summary

This is a Phase 1, open-label, single center, non-randomized study to evaluate the absorption, distribution, metabolism and excretion (ADME) of an oral solution of radiolabeled Ibrexafungerp following repeat administration in healthy male subjects. All subjects will undergo preliminary screening procedures, will remain the clinical unit for approximately 26 days and will receive radiolabeled Ibrexafungerp, orally for 3 days.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mass balance recovery	Mass balance recovery of total radioactivity in urine, faeces and all excreta (urine and faeces): cumulative recovery (CumAe) and cumulative recovery expressed as a percentage of the dose (Cum%Ae)	Day 26
Primary	Metabolite identification in plasma, urine and faeces	Determination of primary metabolites using liquid chromatography-radio-detection	Day 26
Primary	Area under the plasma concentration versus time curve (AUC) of Ibrexafungerp	Area under the plasma concentration versus time curve (AUC) will be estimated where possible	Day1 and Day 4
Primary	Area under the plasma concentration versus time curve (AUC) of total radioactivity	Area under the plasma concentration versus time curve (AUC) of total radioactivity in blood where possible	Day 1 and Day 4
Primary	Peak Plasma Concentration (Cmax) of Ibrexafungerp	Peak Plasma Concentration (Cmax) of Ibrexafungerp will be estimated	Day 1 and Day 4
Secondary	Routes and rates of elimination of [14^C]-Ibrexafungerp	Determination of routes and rates of elimination of [14C]-Ibrexafungerp primarily by Ae total radioactivity for urine and faeces.	Day 26
Secondary	Distribution of total radioactivity into blood cells	Evaluation of whole blood plasma concentration ratios for total radioactivity	Day 4
Secondary	Safety of Ibrexafungerp	Number of participants with treatment-related adverse events as assessed by the investigator.	Day 4
