Clinical Trial Summary

A phase II double-blind placebo-controlled parallel group clinical trial that will randomize 90 subjects to investigate whether pregabalin (PGB) combined with Lofexidine (LFX) can reduce opioid withdrawal-related subjective effects, and investigate, whether the PGB/LFX combination can increase the proportion of patients with an opioid use disorder (OUD) who complete detoxification and transition to antagonist treatment with extended-release injectable naltrexone (XR-NTX).


Clinical Trial Description

An inpatient detoxification study where pregabalin (PBG) will be given orally at a starting dose of up to 600 mg daily (group 1) tapered to 100 mg daily over 7 days; given with lofexidine (LFX) starting at 2.16 mg daily and declining to 0.72 mg over 7 days. On day 8, subjects are offered an injection of XR-NTX if they provide a urine sample that is negative for opioids and buprenorphine and pass a naloxone challenge. All subjects, regardless of whether or not they receive XR-NTX, will be given a referral and appointment for follow-up treatment when they leave the inpatient detoxification program. ;
