|Condition or disease||Intervention/treatment||Phase|
|Opioid Withdrawal (Disorder)||Drug: Lofexidine Drug: Placebo||Phase 2|
This randomized, double-blind, placebo-controlled pilot study will evaluate the safety and effectiveness of LUCEMYRA in the treatment of opioid withdrawal during an opioid taper in subjects with chronic non-cancer pain.
Subjects will begin a planned 14-day complete taper of their pre-study opioid medications and will be randomly assigned (1:1) to either LUCEMYRA or matching placebo. Study drug will be administered through the opioid taper and for 5 days after the opioid taper is completed. Study drug will then be tapered over a 4-day period for a total of approximately 21 days exposure to study drug.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||60 participants|
|Intervention Model:||Parallel Assignment|
|Masking:||Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)|
|Masking Description:||All subjects, study personnel (including the Investigator, study coordinator(s), pharmacist/designee), and the Sponsor will be blinded to the identity of the study drug (active or placebo) administered to subjects.|
