Study Arms:
- ASP8062 in combination with buprenorphine/naloxone (Type: EXPERIMENTAL): Participants received multiple sublingual doses of buprenorphine/naloxone on days 1 through 26. In the Investigational Period participants were on a stable daily dose of buprenorphine/naloxone on days 5 through 18. After randomization on day 12, participants received a single oral dose of ASP8062 concomitantly with buprenorphine/naloxone. The stable dose of buprenorphine/naloxone was down titrated from days 19 through 26.
- Placebo ASP8062 in combination with buprenorphine/naloxone (Type: PLACEBO_COMPARATOR): Participants received multiple sublingual doses of buprenorphine/naloxone on days 1 through 26. In the Investigational Period participants were on a stable daily dose of buprenorphine/naloxone on days 5 through 18. After randomization on day 12, participants received a single oral dose of placebo concomitantly with buprenorphine/naloxone. The stable dose of buprenorphine/naloxone was down titrated from days 19 through 26.
