About this study

Official title: A Randomized, Double-Blind, Study of the Analgesic Efficacy and Safety of Flexible Dose Q8003 Versus Low Dose Q8003 in Patients Who Have Undergone Primary Unilateral Total Knee Arthroplasty

This is a Phase 3, two-arm, double-blind study of efficacy and safety of Q8003 in patients who have undergone primary unilateral total knee arthroplasty

Read the detailed description

This Phase 3 study is a two-arm, double-blind study to:

  • compare the analgesic efficacy and safety of the flexible regimen of Q8003 (6 mg/4 mg up to 24 mg/16 mg) administered every 4-6 hours over a 48-hour Treatment Period versus low dose Q8003 (every 4-6 hours 3 mg/2 mg with a 6 mg/4 mg loading dose) to inpatients with moderate to severe postoperative pain who have undergone primary unilateral total knee arthroplasty.
  • to evaluate the efficacy and safety of Q8003 when administered in the Voluntary Extension Period starting at 48 hours after the initial dosing and extending up to Day 12.
Being tested
Flexible dose Q8003 (morphine sulfate and oxycodone hydrochloride), Low dose Q8003 (morphine sulfate and oxycodone hydrochloride)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Flexible dose Q8003 (morphine sulfate and oxycodone hydrochloride) and Low dose Q8003 (morphine sulfate and oxycodone hydrochloride) in people with Postoperative Pain, run by QRxPharma Inc. at 11 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 5 inclusion and 10 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 May 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 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 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Difference in pain intensity scores from baseline (time frame: 48 hours). 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 17 May 2012.
