Study in Healthy Male Subjects Designed to Assess the Mass Balance Recovery, Metabolite Profile and Metabolite Identification of [14C] LC15-0444

LG Life Sciences6 enrolled

Overview

This was an open-label, non-randomised, single-dose study in 6 healthy male subjects. Subjects attended a screening visit within 28 days before drug administration. Subjects were admitted to the clinical unit on the morning of the day before dosing (Day -1) and received a single oral administration of study drug in a fasted state on Day 1. Subjects were resident in the clinic for up to 7 days after dosing; they could be discharged sooner if a mass balance cumulative recovery of \>95% was achieved, or if a mass balance cumulative recovery of \>90% was achieved and \<1% was collected within 2 separate, consecutive 24 h periods. At specified times during the study period, blood samples were taken and urine and faeces were collected for PK analysis. Safety assessments were also performed.
