About

A study designed to characterize the pharmacokinetic (PK) profile of CORT125134 following a single 150-mg oral dose of the Phase 2 capsule formulation of CORT125134 in 8 healthy male subjects.

Full description

Following an overnight fast, subjects will be administered a single 150-mg oral dose of CORT125134 capsules on the morning of Day 1. Blood samples for determination of PK parameters will be collected predose and at serial time points up to 120 hours after study drug administration. The secondary objective of the study is to characterize the PK profile of metabolite CORT125201 following a single 150-mg oral dose of the Phase 2 capsule formulation of CORT125134 in 8 healthy male subjects.
