Study Summary

The purpose of this study is to measure safety and efficacy and to determine dose-response relationship for INDV-2000 in participants with moderate to severe Opioid Use Disorder (OUD) who are new to treatment, have recently initiated or completed short-term medically supervised withdrawal with transmucosal (TM) buprenorphine, and are interested in transitioning to a non opioid treatment.

  5. The participant will initiate, or is undergoing medically supervisedwithdrawal, and

  • In the opinion of the investigator, the participant is able toachieve a stable dose of transmucosal (TM) buprenorphine between ≤24mg inclusive prior to randomization.
  • Current opioid agonist treatment does not exceed 35 days from thestart of TM buprenorphine to the end of Screening window.

Study Description

From Day 1 to Day 7, TM buprenorphine and randomized INDV-2000/Placebo will be administered, INDV-2000/Placebo will be administered alone from Day 8 onward.
