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

• Status: Recruiting
• Trial end date: 2023-08-31
• Target enrollment: 0
• Participant gender: Male

Summary

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.

5. Clinically significant illness that requires medical treatment within 8 weeks or a clinically significant infection that requires medical treatment within 4 weeks prior to dosing

6. A prolonged QT/QTc interval (QTcF [corrected QT interval by Fridericia] >450 millisecond [ms]) as confirmed by a repeated ECG at Screening or Baseline, or a history of risk factors for torsade de pointes (example, heart failure, hypokalemia, family history of long QT Syndrome), or the use of concomitant medications that prolonged the QT/QTc interval

7. Known history of clinically significant drug, food allergies, or presently experiencing any seasonal or perennial allergy at Screening and Baseline (Day -1)
