Clinical Trial Summary

The study will enroll 30 opioid-dependent participants into an open-label pilot outpatient study of methods to facilitate induction and stabilization onto XR-NTX. There will be three different methods of XR-NTX induction using increasing doses of oral naltrexone and buprenophine.

Description:

Procedure 1: 5-day induction with increasing doses of oral naltrexone. Participants will receive XR-NTX on day five together with buprenorphine, and will continue receiving buprenorphine for 4 weeks until they receive 2nd XR-NTX dose. Procedure 2: 10-day induction with buprenorphine administered daily and increasing daily doses of oral naltrexone beginning on day 2 . On day 10 participants will receive XR-NTX dose, and another one 4 weeks later. No buprenorphine will be given beyond day 10. Procedure 3: 10-day induction with buprenorphine administered daily and increasing daily doses of oral naltrexone beginning on day 2 . On day 10 participants will receive XR-NTX dose, and another one 4 weeks later. Buprenorphine will continue for 4 weeks until the 2nd XR-NTX dose. All participants will receive weekly therapy with a study psychiatrist. All participants will receive open-label medication.
