Primary

MeasureTime frame
Main Objective: Additional main objective during the study 5.

Additional main objectives at week 26 and week 52 after treatment discontinuation 6. Participants current use of illicit substances 26 weeks and 52 weeks after the end of XR-NTX treatment, based on interview 7.
