Trial summary

The purpose of this study is to compare the analgesic efficacy and safety of tramadol HCl ER 100 mg, 200 mg and 300 mg once a day (QD), with placebo in patients with moderate to severe pain due to OA. For the purposes of this study, celecoxib will serve as a positive control to validate the sensitivity of the model. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients with American College of Rheumatology (ACR) Functional Class I-III OA of the knee or hip;
  • Patients with involvement of knee or hip joint that warrants treatment with COX-2 selective inhibitors, NSAIDs, acetaminophen, or opioid analgesics for at least 75 of the 90 days preceding the screening visit;
  • Patients with a pain intensity score in index joint >= 40 mm on the visual analog scale(VAS) at the baseline visit;
  • Patients who are able to discontinue acetaminophen, NSAIDS, COX-2 selective inhibitors and other analgesics during the washout period and all analgesics other than the study medication throughout the study;
  • Patients who are able to understand the study procedures and complete the pain scales.

Who cannot join

  • Patients with a medical condition, other than OA, uncontrolled with treatment or any clinically significant condition that, in the investigator's opinion, precludes study participation or interferes with the assessment of chronic pain and other OA symptoms;
  • Patients with a diagnoses of inflammatory arthritis, gout, pseudo-gout or Paget's disease, that, in the investigator's opinion, interferes with the assessment of pain and other symptoms of OA;
  • Patients with a diagnosis of chronic pain syndrome;
  • Patients with an ACR or a clinical diagnosis of fibromyalgia;
  • Patients with any other clinically significant form of joint disease or prior joint replacement surgery at the index joint;
  • Patients with an anticipated need for surgery or other invasive procedure in the index joint.

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, Celecoxib 200 mg and Placebo in the Treatment of Osteoarthritis of the Knee and/or Hip.

The purpose of this study is to compare the analgesic efficacy and safety of tramadol HCl ER 100 mg, 200 mg and 300 mg once a day (QD), with placebo in patients with moderate to severe pain due to OA. For the purposes of this study, celecoxib will serve as a positive control to validate the sensitivity of the model. The study hypothesis is that tramadol HCl ER is safe and effective in the treatment of 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 IR tramadol necessitates every 4-6 hour dosing to maintain optimum levels of analgesia in chronic pain. The study medication in this study is a once-daily, extended release (ER) tramadol formulation. This is a 12-week multicenter, double-blind, randomized, dose-ranging, placebo and positive-controlled, parallel-group study. For the purpose of this study, celecoxib serves as a positive control to validate the sensitivity of the model. Patients with OA functional Class I-III of the knee or hip, with moderate to severe pain 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 the 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, celecoxib 200 mg or placebo, once daily. During the titration period (Days 1-9) all patients will be contacted by phone every few days to ensure they do not experience unmanageable pain or unacceptable side effects. Efficacy and safety evaluations will be collected at study visits occurring at Weeks 1, 2, 3, 6, 9 and 12 or at the time of early termination. Study medication will be discontinued at Week 12 and patients will return after 1 week for a post-treatment visit (Week 13).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

Secondary outcomes (1)
  1. The secondary outcomes include: change from baseline in the daily arthritis pain intensity scores from patient diaries, WOMAC OA stiffness subscale scores, OA pain intensity VAS for index and non-index joints, and Chronic Pain Sleep Inventory scale

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing tramadol HCl ER; celecoxib in people with Chronic Pain, run by Bausch Health Americas, Inc..

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 21 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.

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?
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 21 Jun 2012.
