Study Endpoints

Primary Endpoints

Number of subjects with Adverse Events (AEs) as a measure of safety
29 weeks

AEs that occurred after the signing of the informed consent until 4 weeks after the implants have been removed were followed. Serious AEs and AEs that were designated as possibly related to study drug were followed until resolution or stabilization.

CDF of the percent of urine samples negative for opioids in Probuphine and Placebo groups from weeks 1-24
1-24 weeks
CDF of the percent of urine samples negative for opioids from weeks 1-24 with imputation based on illicit drug use self-report data for Probuphine and placebo groups
1-24 weeks
Number of subjects with adverse events as a measure of safety
approx. 26 weeks

Adverse events that occurred after the signing of the informed consent until 14 days after study drug treatment has been discontinued, or AEs designated as possibly-related to study drug and all Serious AEs until resolution or stabilization, were followed.
