About this study
Official title: Double-Blind, Randomized,Dose-Ranging, Parallel-Group Comparison Of The Efficacy And Safety Of Extended-Release Tramadol Hydrochloride(Tramadol HCl ER)100 Mg, 200 Mg, 300 Mg, And 400 Mg With Placebo In The Treatment Of Osteoarthritis Of Knee And/Or Hip
The purpose of this study is to compare the effectiveness of multiple doses of once daily tramadol HCl ER (100, 200, 300 and 400 mg) to placebo in patients with moderate to severe pain due to OA. The study hypothesis is that tramadol HCl ER is safe and effective in the treatment of patients with moderate to severe pain due to OA.
Read the detailed description
Immediate release (IR) tramadol has demonstrated efficacy in several pain conditions including: obstetrical, gynecological, orthopedic, abdominal, and oral surgery. The short elimination half-life of tramadol IR necessitates every 4-6 hour dosing to maintain optimal levels of analgesia in chronic pain. The study medication in this study is a once-daily, extended-release tramadol formulation. This is a 12-week multi-center, double-blind, randomized, dose-ranging, parallel-group, fixed-dose, placebo-controlled study. Patients with OA Functional Class I-III of the knee or hip (index joint) are eligible for participation, if appropriate criteria are met. During a 2-7 day washout period, the use of all analgesic medications will be discontinued. Eligible patients experiencing moderate to severe pain (<=40 mm on a 100 mm visual analog scale) in the index joint to be evaluated and who meet all other study criteria will enter in a 2-week,double-blind titration period. During this period, patients will be randomly assigned to receive treatment with tramadol HCl ER 100 mg, 200 mg, 300 mg, 400 mg or placebo, once a day. Patients will be titrated to their assigned dose between study days 1 - 15 and will continue at that dose for the remainder of the study (Week 12). Efficacy and safety evaluations will be collected at study visits occurring at Weeks 1, 2, 3, 6, 9 and 12 or at early termination. Study medication will be discontinued at Week 12 and patients will return after 1 week for a post-treatment visit (Week 13). Patients with unmanageable pain or with unacceptable side effects will be discontinued from the study and alternate analgesic therapy initiated, as appropriate.

Clinical summary

The purpose of this study is to compare the effectiveness of multiple doses of once daily tramadol HCl ER (100, 200, 300 and 400 mg) to placebo in patients with moderate to severe pain due to OA. The study hypothesis is that tramadol HCl ER is safe and effective in the treatment of patients with moderate to severe pain due to OA.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Tramadol HCl ER in people with Chronic Pain, run by Bausch Health Americas, Inc. at 1 site 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 6 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 Aug 2012. 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 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?
The primary outcome is the change from baseline to Week 12 in the WOMAC OA Index pain and physical function subscale scores and the patient global assessment of disease activity.. 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 NCT00325858, 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 27 Aug 2012.
