A Six-Month Randomized Controlled Trial (RCT) of Probuphine Safety and Efficacy in Opioid Addiction

Phase 3
Completed
Conditions
Opioid Dependency
Interventions
Drug: Probuphine (buprenorphine implant)
Drug: placebo implant
Registration Number
NCT01114308
Lead Sponsor
Titan Pharmaceuticals
Brief Summary

Probuphine (buprenorphine implant) is an implant placed just below the skin containing buprenorphine (BPN). BPN is an approved treatment for opioid dependence. This study will confirm the efficacy of Probuphine vs. placebo and compare Probuphine treatment verses treatment with sublingual buprenorphine in the treatment of patients with opioid dependence.

  • Females of childbearing potential or a fertile male, must use a reliable means of contraception
Exclusion Criteria
  • Current diagnosis of Acquired Immune Deficiency Syndrome (AIDS)
  • Received any medication-assisted treatment for opioid dependence (e.g., methadone, BPN) within the previous 90 days
  • Current diagnosis of chronic pain requiring opioids for treatment
  • Candidates for short-term opioid treatment (<6 months) only, or opioid detoxification therapy
  • Pregnant or lactating female?
  • Previous hypersensitivity or allergy to BPN, EVA-containing substances, or naloxone
  • Current use of agents metabolized through Cytochrome P450 3A4 (CYP 3A4) such as azole antifungals (e.g., ketoconazole), macrolide antibiotics (e.g., erythromycin), or protease inhibitors (e.g., ritonavir, indinavir, and saquinavir)
  • History of coagulopathy within the past 90 days, and/or current anti-coagulant therapy such as warfarin
  • Meet the DSM-IV-TR criteria for dependence on any other psychoactive substances other than opioids or nicotine (e.g., alcohol, sedatives)
  • Significant medical or psychiatric symptoms, cognitive impairment, or other factors which in the opinion of the Investigator would preclude compliance with the protocol, subject safety, adequate cooperation in the study, or obtaining informed consent
  • Current medical conditions such as severe respiratory insufficiency that may prevent the subject from safely participating in study, or any pending legal action that could prohibit participation or compliance in the study
  • Exposure to any investigational drug within the previous 8 weeks
  • Previous exposure to Probuphine, or prior implantation with a placebo implant in the context of a Probuphine clinical trial
  • Presence of aspartate aminotransferase (AST) levels greater than or equal to 3 X the upper limit of normal, alanine aminotransferase (ALT) levels greater than or equal to 3 X the upper limit of normal, total bilirubin greater than or equal to 1.5 X the upper limit of normal, or creatinine greater than 1.5 X upper limit of normal on the screening laboratory assessments
  • Clinically significant low platelet count on the screening laboratory assessments
