Buprenorphine-Fentanyl Interaction Study
A Study Examining the Pharmacodynamics Interaction Between Buprenorphine and Fentanyl
Study Overview
Status
Conditions
Detailed 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.

EXPERIMENTAL: Part A (Healthy Participants): Placebo-Buprenorphine Low
Three treatment periods consisting of 3 days each of investigational treatment
Fentanyl was administered as a bolus over 90 seconds in escalating doses of 0.075, 0.15, 0.25 and 0.35 mg/70 kg. Each dosing period was followed by 10-17 days of washout. |
Buprenorphine intravenous (IV) injection given as a primed-continuous infusion. Low Dose: initial bolus (0.05 mg/70 kg) administered over 15 minutes and infusion continued (0.02 mg/70 kg/hour infusion rate) to complete 360 minutes of administration targeting 0.2 ng/ml.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in peak ventilatory depression will be measured.
Time Frame: 6 hours (during study drug infusion)
|
Peak ventilatory depression (change in minute ventilation) will be calculated based on a 1-minute average of the ventilation data of each individual subject/patient.
For buprenorphine or placebo, absolute changes and percentage changes are calculated from the baseline value.
For fentanyl, absolute changes and percentage changes for each bolus are calculated from the baseline value and from the pre-fentanyl baseline value immediately before the first fentanyl bolus
|
6 hours (during study drug infusion)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number (percentage) of subjects who experience apnoea for each fentanyl dose during the placebo treatment vs. the buprenorphine treatment
Time Frame: 6 hours
|
Apnoea is defined as a 20-second pause in respiration.
If apnoea is observed at any fentanyl dose, the subject will be classified as "experienced apnoea" for that dose and any higher dose planned will be withheld
|
6 hours
|
Number (percentage) of subjects who require stimulation for breathing for each fentanyl dose during the placebo treatment vs. the buprenorphine treatment.
Time Frame: 6 hours
|
If a subject required stimulation for breathing at a fentanyl dose and the next higher dose was withheld, the subject will be classified as requiring breath stimulation for all withheld doses
|
6 hours
