A Study of the Excretion Balance of Radiocarbon and the Pharmacokinetics and Metabolic Profile of TRO19622 (Olesoxime)

A Single-Center, Open-Label, Single Oral Dose Phase I Study to Determine the Excretion Balance of Radiocarbon (i.e., the Sum of 14C-Labeled TRO19622 and Its 14C-Metabolites) and to Investigate the Pharmacokinetics and Metabolic Profile of TRO19622

This Phase I study is designed to determine the excretion balance of radiocarbon, as the sum of carbon-14 (14C)-labeled TRO19622 and its 14C-metabolites, and to investigate the pharmacokinetics and metabolic profile of TRO19622 (olesoxime) in healthy participants.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Olesoxime; Participants will receive a single dose of liquid suspension of 14C-labeled olesoxime containing an equivalent of 600 milligrams (mg) of the compound. The total amount of administered radiocarbon will be 93 microcuries (mcCi), or 3.447 megabecquerels (MBq).
