What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Responders
A responder is defined as a subject whose maximum (across all time points) clinical opiate withdrawal scale (COWS) total score is ≥13. COWS scores range 0 to 4 or 5 on 11 items related to opiate withdrawal signs or symptoms; total score range 0 to 48 where 0-4 = no withdrawal and 5-12 = mild, 13-24 = moderate, 25-36 = moderately severe, more than 36 = severe withdrawal.
Measured: Pre-dose (-0.5), 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, 9, 12, 12.5, 13, 13.5, 14, 16, and 24 (or end of study visit) hours post 1st study drug dose on each day of administration (period 1 [day 1] and period 2 [day 2]) in each treatment sequence
Maximum COWS Total Score
Investigator-rated COWS scores range 0 to 4 or 5 on 11 items related to opiate withdrawal signs or symptoms; total score range 0 to 48 where 0-4 = no withdrawal and 5-12 = mild, 13-24 = moderate, 25-36 = moderately severe, more than 36 = severe withdrawal. The maximum COWs total score is defined as the maximum COWs total score across all time points during the corresponding treatment period after study drug administration for each subject.
Measured: Pre-dose (-0.5), 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, 9, 12, 12.5, 13, 13.5, 14, 16, and 24 (or end of study visit) hours post 1st study drug dose on each day of administration (period 1 [day 1] and period 2 [day 2]) in each treatment sequence
Change From Baseline in Maximum COWS Total Score
Investigator-rated COWS scores range 0 to 4 or 5 on 11 items related to opiate withdrawal signs or symptoms; total score range 0 to 48 where 0-4 = no withdrawal and 5-12 = mild, 13-24 = moderate, 25-36 = moderately severe, more than 36 = severe withdrawal. The change from baseline in maximum COWS total score is determined as the difference between the maximum COWs total score and the baseline COWs total score.
Measured: Pre-dose (-0.5; baseline), 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, 9, 12, 12.5, 13, 13.5, 14, 16, and 24 (or end of study visit) hours post 1st study drug dose on each day of administration (period 1 [day 1] and period 2 [day 2]) in each treatment sequence
Secondary outcomes (2)
Change From Baseline in COWS Total Score Over Time
Investigator-rated COWS scores range 0 to 4 or 5 on 11 items related to opiate withdrawal signs or symptoms; total score range 0 to 48 where 0-4 = no withdrawal and 5-12 = mild, 13-24 = moderate, 25-36 = moderately severe, more than 36 = severe withdrawal.
Measured: Pre-dose (-0.5; baseline), 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, 9, 12, 12.5, 13, 13.5, 14, 16, and 24 (or end of study visit) hours post 1st study drug dose on each day of administration (period 1 [day 1] and period 2 [day 2]) in each treatment sequence
Change From Baseline in "Pain Now" Over Time Using NRS
Subject rating of pain intensity using 11-point numerical rating scale (NRS) where 0=no pain and 10=pain as bad as you can imagine.
Measured: Pre-dose (-0.5; baseline), 0.5, 1, 2, 4, 9, 12, 12.5, 13, 14, 16, and 24 (or end of study visit) hours post 1st study drug dose on each day of administration (period 1 [day 1] and period 2 [day 2]) in each treatment sequence

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Buprenorphine, Oxycodone and Morphine sulfate in people with Pain, run by BioDelivery Sciences International at 3 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 Feb 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Responders (time frame: Pre-dose (-0.5), 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, 9, 12, 12.5, 13, 13.5, 14, 16, and 24 (or end of study visit) hours post 1st study drug dose on each day of administration (period 1 [day 1] and period 2 [day 2]) in each treatment sequence). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Feb 2017.
