A Study to Determine the Absolute Bioavailability and the Absorption, Metabolism, and Elimination Properties of Carbon-14 (14C)E7386 in Healthy Male Participants

The primary purpose of this study is to evaluate the absolute bioavailability of E7386 following a single oral dose of E7386 as a one 40 milligram (mg) immediate release (IR) tablet and concomitant intravenous (IV) microdose of (14C)E7386 (100 mcg [microgram]) solution for Part 1 and to determine the pharmacokinetic (PK) and excretion of E7386 following a single 40 mg powder in capsule (PIC) oral administration of (14C)E7386 for Part 2.

    The C-SSRS is an interview-based rating scale to systematically assess any suicidality, suicidal behavior, or suicidal ideation. Any suicidality is emergence of any suicidal ideation or suicidal behavior. Any suicidal behavior is indicated when response is "yes" for any these questions- actual attempt to suicide, engaged in non-suicidal self-injurious behavior, interrupted attempt, aborted attempt, preparatory acts. Any suicidal ideation is indicated when response is "yes" for any of these questions- wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent to suicide.
