          5. Have not received medication-assisted treatment for opioid use disorder within 60 days
             prior to randomization.

          6. Considered by the Investigator to be a good candidate for BPN treatment, based on
             medical and psychosocial history.

          7. Male or Female subjects of childbearing potential must be willing to use a reliable
             method of contraception during the entire trial (Screening visit to Follow-up visit)

        Exclusion Criteria:

          1. Current diagnosis of Acquired Immune Deficiency Syndrome (AIDS).

          2. Current diagnosis of chronic pain requiring opioids for treatment.

          3. Current DSM-V diagnosis of moderate to severe substance use disorder on any other
             psychoactive substances other than opioids, caffeine or nicotine (e.g., alcohol,
             cocaine, sedatives).

          4. Pregnant or lactating or planning to become pregnant during the trial.

          5. Hypersensitivity or allergy to BPN or other opioids, naloxone or other opioid
             antagonists, or excipients of CAM2038 or SL BPN.

          6. Requires current use of agents that are strong inhibitors or inducers of cytochrome
             P450 3A4 (CYP3A4) such as some azole antifungals (e.g., ketoconazole), macrolide
             antibiotics (e.g., clarithromycin), or protease inhibitors (e.g., ritonavir,
             indinavir, and saquinavir).

          7. Subjects with active signs or symptoms of hepatitis and requiring treatment. Subjects
             with no acute signs of inflammation, and no clinical necessity for therapy will be
             allowed, at the discretion of the Investigator.

          8. Recent history of or current evidence of suicidal ideation or active suicidal behavior
             as based on the Columbia Suicide Severity Rating Scale (C-SSRS) ("Yes" responses to

         10. Exposure to any investigational drug within the 4 weeks prior to Screening.

         11. Participants with a history of risk factors of Torsades de Pointes (e.g., heart
             failure, hypokalemia, family history of Long QT Syndrome) or an electrocardiogram
             (ECG) demonstrating a Fridericia's corrected QT interval (QTcF) >450 msec in males and
             QTcF >470 in females at screening.

         12. Aspartate aminotransferase (AST) levels >3 X the upper limit of normal, alanine
             aminotransferase (ALT) levels >3 X the upper limit of normal, total bilirubin >1.5 X
             the upper limit of normal, or creatinine >1.5 X upper limit of normal on the Screening
             laboratory assessments, or other clinically significant laboratory abnormalities,
             which in the opinion of the Investigator may prevent the subject from safely
             participating in trial.

         13. Significant symptoms, medical conditions, or other circumstances which, in the opinion
             of the Investigator, would preclude compliance with the protocol, adequate cooperation
             in the trial or obtaining informed consent, or may prevent the subject from safely
             participating in trial (including, but not limited to, the risks described as
             precautions, warnings, and contraindications in the current version of the
             Investigator's Brochure for CAM2038).

         14. Is an employee of the Investigator or the trial site, with direct involvement in the
