ALK21-006: Long-Term Study of Medisorb® Naltrexone (VIVITROL®)
A Randomized, Open Label, Long-Term, Multi-Center Study of the Safety of Medisorb® Naltrexone
This was a Phase 3 multicenter randomized, open-label, safety study assessing the safety of repeat doses of Medisorb® naltrexone 380 mg (VIVITROL®) administered for up to 1 year to adults with alcohol and/or opioid dependence as defined by Diagnostic and Statistical Manual of Mental Health Disorders (DSM-IV) criteria. Eligible subjects were randomized in a 6:1 ratio to receive 1 of the following regimens: a single intramuscular (IM) injection of VIVITROL administered once every 4 weeks or oral naltrexone 50 mg administered daily.

Safety evaluations included physical examinations, electrocardiograms (ECGs), laboratory measures (including plasma concentrations of naltrexone and 6β-naltrexol), assessments of injection sites, and adverse events (AEs).

All subjects received psychosocial support at each study visit for the duration of the study, with interim telephone contact 2 weeks after each monthly visit.
