About this study

Official title: An Open-Label Titration Followed by a Randomized, Double-Blind, Placebo-Controlled Study to Assess the Efficacy, Tolerability, and Safety of Oxymorphone Extended Release Tablets in Opioid-Naïve Patients With Chronic Low Back Pain

The purpose of this study is to evaluate the analgesic efficacy and safety of oxymorphone extended release in non-cancer patients with chronic low back pain.

Read the detailed description

Patients with low back pain who are sub-optimally responsive to their current analgesic treatment begin open-label treatment with oxymorphone extended release (ER). During the Open-Label Titration Period, patients will receive daily oxymorphone ER by mouth (PO) q12h. The investigator will initiate the Open-Label Titration Period using study drug at a dose of 5 mg PO q12h for 2 days; thereafter, patients will continue receiving 5 mg q12h or be titrated at increments of 5-10 mg q12h every 3-7 days until stabilization is achieved. The goal of the Open-Label Titration Period is to determine for each patient a fixed dose of study medication that is tolerated and achieves adequate analgesia. Stabilized patients will be randomiozed to either continue with current dose of oxymorphone ER or receive placebo for a total duration of 12 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Oxymorphone Extended Release in people with Chronic Pain, run by Endo USA Inc., a Keenova Therapeutics Company at 33 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 7 inclusion and 15 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 2 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 33 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?

Change in pain intensity from baseline (pre-randomization) to last assessment.. 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 NCT00225797, which also lists 3 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 2 Jan 2024.
