What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Pain Intensity for "Average Pain Over the Last 24 Hours" Score
Mean pain intensity for "average pain over the last 24 hours" score (on an 11-point numerical rating scale where 0 = no pain and 10 = pain as bad as you can imagine).
Measured: Week 12
Secondary outcomes (4)
Medical Outcome Study Sleep Scale - Revised (MOS Sleep-R) - Sleep Disturbance Subscale
The MOS Sleep-R is a brief, self-administered 12-item assessment designed to measure key aspects of sleep. It includes a sleep problems index and 6 subscales - sleep disturbance, sleep adequacy, daytime somnolence, snoring, awaken short of breath or with headache, and quantity of sleep. The sleep disturbance subscale comprised the responses to questions 1, 3, 7, and 8 on the assessment. The individual responses for each question were recorded on a 5-point scale with options ranging from 1 - "all of the time" to 5 - "none of the time". Sleep disturbance scores were transformed linearly on a scale of 0-100. A higher value indicates a better score; therefore, a higher score indicates a better sleep pattern.
Measured: Weeks 4, 8, and 12
Patient Global Impression of Change (PGIC)
The PGIC is an ordinal scale which assesses the change in overall status relative to the start of the study. The scale has only 1 item, which measures global change of overall status by the subject on a 7-point scale (very much improved, much improved, minimally improved, no change, minimally worse, much worse, very much worse), where 1 = very much improved and 7 = very much worse. The proportion of subjects responding "very much improved" and "much improved" was summarized by treatment group.
Measured: Week 12
Responder Analysis for Subjects With a ≥ 30% Reduction in Pain Compared to Baseline
A subject's response to treatment was defined as the percentage reduction from the screening mean pain score to the mean pain intensity at week 12 of the double-blind period.
Measured: Baseline to Week 12
Responder Analysis for Subjects With a ≥ 50% Reduction in Pain Compared to Baseline
A subject's response to treatment was defined as the percentage reduction from the screening mean pain score to the mean pain intensity at week 12 of the double-blind period.
Measured: Baseline to Week 12

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Hydrocodone bitartrate q24h film-coated tablets in people with Chronic Low Back Pain, run by Purdue Pharma LP at 102 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 4 inclusion and 18 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 10 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 102 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 4 Dec 2014). 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?
Mean Pain Intensity for "Average Pain Over the Last 24 Hours" Score (time frame: Week 12). 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 NCT01452529, which also lists 2 linked publications.
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 10 Mar 2020.
