Evaluation of Buprenorphine Extended-Release Subcutaneous Injection at Alternative Injection Locations

Extended-release buprenorphine (SUBLOCADE®) injection is currently approved for subcutaneous administration in the abdomen for treatment of opioid use disorder (OUD). Having alternative injection sites is desirable to provide additional flexibility to patients, particularly for those who may prefer less visible or more convenient injection locations. The primary objective of this study is to assess the relative bioavailability of extended-release buprenorphine when administered at alternative injection locations (test treatments), in comparison to the abdomen (reference treatment).
