NCT00325858

Brief 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.

Outcome Measures

Primary Outcomes (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)

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

Interventions

Eligibility Criteria

Age18 Years - 74 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with American College of Rheumatology (ACR) Functional Class I-III OA of the knee or hip
  • Patients with involvement of at least one knee or hip joint that warrants treatment with COX-2 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 throughout the study
  • Patients who are able to understand the study procedures and complete pain scales

You may not qualify if:

  • 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 diagnosis 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 a 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
