Official title

A Clinical Trial to Study the Effect of a Single Dose of Ulonivirine on the Pharmacokinetics of Methadone

Overview

This study is designed to determine the effect of ulonivirine (MK-8507) on methadone in the body. Participants will take methadone alone and then methadone with ulonivirine to see if ulonivirine changes how the body processes methadone.

Interventions

  • Drug Ulonivirine
    Oral Tablet
  • Drug Methadone
    Oral (per local guidelines)

Primary outcome measures

  • Dose-Normalized Area Under the Plasma Concentration Time Curve From 0-24 Hours Postdose (AUC0-24) of R-Methadone [Time frame: Up to 24 hours post-dose]
  • Dose-Normalized AUC0-24 of S-Methadone [Time frame: Up to 24 hours post-dose]
Secondary outcome measures (12)
  • Dose-Normalized Maximum Plasma Concentration (Cmax) of R-Methadone [Time frame: Up to 24 hours post-dose]
  • Dose-Normalized Plasma Concentration 24 Hours Postdose (C24) of R-Methadone [Time frame: 24 hours post-dose]
  • Time to Maximum Plasma Concentration (Tmax) of R-Methadone [Time frame: Up to 24 hours post-dose]
  • Dose-Normalized Cmax of S-Methadone [Time frame: Up to 24 hours post-dose]
  • Dose-Normalized C24 of S-Methadone [Time frame: 24 hours post-dose]
  • Tmax of S-Methadone [Time frame: Up to 24 hours post-dose]
  • Dose-Normalized AUC0-24 of Total Methadone [Time frame: Up to 24 hours post-dose]
  • Dose-Normalized Cmax of Total Methadone [Time frame: Up to 24 hours post-dose]
  • Dose-Normalized C24 of Total Methadone [Time frame: 24 hours post-dose]
  • Tmax of Total Methadone [Time frame: Up to 24 hours post-dose]
  • Number of Participants With Adverse Events (AEs) Following Methadone + Ulonivirine Coadministration [Time frame: Up to 16 Days]
  • Number of Participants Discontinuing Study Therapy Due to AEs Following Coadministration of Methadone and Ulonivirine [Time frame: Up to 16 Days]
