Healthy Clinical Trial - Buprenorphine-Fentanyl Interaction Study

Status Completed

Clinical Trial Summary

An increase in overdose deaths has been attributed to widespread access to fentanyl and carfentanyl. The study is designed to determine if buprenorphine can change the respiratory depression response to intravenous (IV) fentanyl.

Clinical Trial Description

The study will be performed in 2 parts. Part A is a 3-period study; the first 2 periods have a single-blind, placebo-controlled, cross-over design, where subjects will be randomized in a 1:1 ratio to 2 treatment sequences determined by the order in which they receive buprenorphine or matching placebo. Period 3 is an open-label design where the same subjects will receive buprenorphine only. This period is optional, and will include approximately 6 subjects.

Part B is an open-label study in opioid tolerant patients. All will receive placebo plus fentanyl in Period 1 to permit dose escalation to full respiratory effects of fentanyl before assessing the interaction with buprenorphine. Subjects will receive buprenorphine plus fentanyl during Period 2 to assess the interaction with buprenorphine.

To study ventilation, the dynamic end-tidal forcing technique will be used. This technique enables the Investigator to force end-tidal partial pressure of carbon dioxide and end-tidal partial pressure of oxygen to follow a specific pattern in time. Subjects with a procedure-related adverse event (AE) will be treated according to established ventilatory support and opioid reversal protocols. ;
