Clinical Trial Summary

The primary purpose of this study was to assess the safety and tolerability of multiple doses of buprenorphine/naloxone alone and buprenorphine/naloxone in combination with a single dose of ASP8062. This study also assessed the potential for pharmacokinetic interaction between ASP8062 and buprenorphine/naloxone.


Clinical Trial Description

Participants were screened for up to 28 days prior to first investigational product (IP) administration. Eligible participants were admitted to the clinical unit on day -1 and were residential for a single period of 27 days/26 nights. Participants were discharged from the clinical unit after completion of down-titration on the condition that all required assessments were performed and that there were no medical reasons for a longer stay in the clinical unit; which was the end-of-study visit (ESV). Prior to discharge, participants were provided with local buprenorphine and methadone providers for their reference. ;
