SUBLOCADE Long-term Outcomes

This study will provide the opportunity to generate data on the long-term use of SUBLOCADE under real-world conditions, and to observe enduring changes in lifestyle, health, and sociodemographic factors that are part of the recovery process. Long-term patterns of abstinence/opioid misuse as well as measures of participants' physical, psychological, social, and economic well-being will be monitored to better understand factors associated with recovery from opioid use disorder (OUD). Therefore, this study will observe participants up to a maximum of 4 years.

Treatment and study plan

Primary outcomes

  1. Participants achieving DSM-5 remission, early or sustained, (yes/no) while on initial SUBLOCADE treatment by 6 months and 1, 1.5, 2, 2.5, and 3 years from study Baseline

    Time frame: up to a maximum of 4 years

    • Definition of early remission: None of the criteria for OUD has been met for at least 3 months but for less than 12 months with the exception that Criterion 4 ("Craving, or a strong desire or urge to use opioids,") may be met.
    • Definition of sustained remission: None of the criteria for OUD has been met for at least 12 months with the exception that Criterion 4 ("Craving, or a strong desire or urge to use opioids,") may be met.

Secondary outcomes

  1. Key Secondary: Participants with "no symptoms" or improving by ≥1 DSM-5 severity classification within the last 3 months (moderate to mild, or severe to mild or moderate) relative to study Baseline (yes/no) at Month 6 and Years 1, 2, and 3
