Study of Probuphine in Patients With Opioid Dependence

Stopped early · Phase 3

Conditions studied: Opioid Dependency

In brief

Buprenorphine (BPN) is an approved treatment for opioid dependence; however, in taking oral tablets, patients experience withdrawal and cravings when the variable BPN levels in the blood are low. Probuphine (buprenorphine implant) is an implant placed just beneath the skin that contains BPN. It is designed to provide 6 months of stable BPN blood levels. This study will test the safety and efficacy of Probuphine in the treatment of patients with opioid dependence. Patients who have completed at least 24 weeks of treatment in the Open-Label, Multi-Center Study of Probuphine in Patients with Opioid Dependence (PRO-807 Study), will be re-treated with Probuphine over an additional 24 weeks.

You may qualify if…

• Patients must meet the following eligibility criteria:

• Females of childbearing potential and fertile males must use a reliable means of contraception

You may not qualify if…

• Patients are not eligible for enrollment if any of the following criteria are met:
• Presence of aspartate aminotransferase (AST) levels ≥ 3 X upper limit of normal and/or alanine aminotransferase (ALT) levels ≥ 3 X upper limit of normal and/or total bilirubin ≥ 1.5 X upper limit of normal and/or creatinine ≥ 1.5 X upper limit of normal, measured at the time of the Week 20 Visit for the previous trial (PRO-807 or PRO-808), or any time less than 5 weeks prior to the Implant Visit.
• Current diagnosis of chronic pain requiring opioids for treatment
• Pregnant or lactating females
• Current use of agents metabolized through cytochrome P450 3A4 (CYP 3A4) such as azole antifungals (e.g., ketoconazole), macrolide antibiotics (e.g., erythromycin), and protease inhibitors (e.g., ritonavir, indinavir, and saquinavir)
• Current history of coagulopathy and anti-coagulant therapy (such as warfarin)
• Current use of benzodiazepines other than physician prescribed use
• Significant medical or psychiatric symptoms, cognitive impairment, or other factors which in the opinion of the Investigator, would preclude compliance with the protocol, patient safety, adequate cooperation in the study, or obtaining informed consent
