NCT01848054

Brief Summary

The purpose of the study was to assess the efficacy of induction treatment with buprenorphine/naloxone (BNX) sublingual tablet s compared with induction treatment with buprenorphine only. The hypothesis is that starting directly on OX219 works equally well (e.g. not significantly worse) as starting on buprenorphine only and switching to OX219 on Day 3.

Outcome Measures

Primary Outcomes (1)

  • Retention in Treatment in the Per Protocol Population

    Retention in treatment at Day 3 in the per protocol population (n=256) was defined as the number of patients in each induction arm completing the induction phase and who received study medication on Day 3. Treatment with BNX sublingual tablets was considered non-inferior to generic buprenorphine if the lower limit of the 95% confidence interval for the difference between BNX and generic buprenorphine was ≥-10% in the number of patients retained in treatment on Day 3.

    Day 3

Secondary Outcomes (7)

  • Area Under the Curve (AUC) in Clinical Opiate Withdrawal Scale (COWS) Total Score on Days 1 to 3 Inclusive

    Pre-dose on Days 1-3 and 0.5, 1, 1.5, 3, and 6 hours post-dose on Day 1

  • AUC in Subjective Opiate Withdrawal Scale (SOWS) Total Score on Days 1 to 3 Inclusive

    Pre-dose on Days 1-3 and 0.5, 1, 1.5, 3, and 6 hours post-dose on Day 1

  • AUC in Visual Analog Scale (VAS) Score for Craving on Days 1 to 3 Inclusive

    Pre-dose on Days 1-3 and 0.5, 1, 1.5, 3, and 6 hours post-dose on Day 1

  • Mean Change From Baseline in COWS Total Score After Day 3 (Maintenance Phase)

    Predose on Days 4, 8, 15, 22, and 29

  • Mean Change From Baseline in SOWS Total Score After Day 3 (Maintenance Phase)

    Pre-dose on Days 4, 8, 15, 22, and 29
