What is being measured
The primary outcome is the main question the study is designed to answer.
Drug Liking: Peak Effect (Emax)
Drug liking assesses the degree that a participant likes a drug effect at the time the question is being asked (that is, at the moment). It is scored using a 100 millimeter (mm) bipolar VAS anchored in the center with a neutral anchor of "neither like nor dislike" (score of 50 mm), on the extreme left with "strong disliking" (score of 0 mm) and on the extreme right with "strong liking" (score of 100 mm). Peak Effect (Emax) = Maximum observed score.

Drug liking assesses the degree that a participant likes a drug effect at the time the question is being asked (that is, at the moment). It is scored using a 100 millimeter (mm) bipolar VAS anchored in the center with a neutral anchor of "neither like nor dislike" (score of 50 mm), on the extreme left with "strong disliking" (score of 0 mm) and on the extreme right with "strong liking" (score of 100 mm). Peak Effect (Emax) = Maximum observed score.
Drug Liking: Area Under Effect Curve (AUE) From 0-2 Hour
Time frame: Intervention period: 0.25, 0.5, 0.75, 1, 1.5, 2 hours post-dose

AUE (0-2) = Area under the effect versus time curve from time 0 to 2 hours.

High VAS assesses the effect experienced by the participant on a 100 mm unipolar VAS, where responses are unidirectional and range from 'none' (score of 0 mm) to 'extremely' (score of 100 mm). Emax = Maximum observed score.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing crushed ALO-02 30 mg/3.6 mg and crushed oxycodone IR 30 mg in people with Healthy, run by Pfizer at 1 site in Canada.
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 3 inclusion and 2 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 17 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 17 Jul 2017). 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?
Drug Liking: Peak Effect (Emax) (time frame: Intervention period: 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24 hours post-dose). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01775189, which also lists 1 linked publication.
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 17 Jul 2017.
