Who may be able to join
- Patients with a history of chronic low back pain >= 6 months requiring treatment with NSAIDs, acetaminophen, opioid analgesics, COX-2 selective inhibitors, and/or muscle relaxants for at least 60 of the 90 days preceeding the screening visit; in good health as determined by the investigator on the basis of medical history, physical exam and screening labs; patient's low back pain intensity measures >= 40 mm on a visual analog scale (VAS) at the start of the run-in peroid after the 2-7 day washout; patients who are able to discontinue treatment with NSAIDs, COX-2 selective inhibitors, tramadol, muscle relaxants, opioids, and/or other analgesics during the 2-7 day washout period and all other analgesics throughout the entire study.

About this study
Official title: Double-blind, Randomized, Placebo-controlled, Parallel Group Comparison of the Efficacy and Safety of Extended Release Tramadol (Tramadol ER) 300 mg and 200 mg to Placebo in the Treatment of Chronic Low Back Pain
The purpose of this study is to compare the analgesic efficacy of oral, once-daily tramadol ER 300 mg and 200 mg to placebo in patients with moderate to severe chronic low back pain requiring daily analgesic treatment. The study hypothesis is that tramadol ER is effective in the treatment of moderate to severe chronic low back pain.
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 in order 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 multicenter, double-blind, randomized, placebo-controlled, parallel-group study. At the Screening Visit, patients eligible for study participation by medical history, physical exam and other evaluations will enter a 2-7 day washout period during which time analgesics will not be allowed. At Visit 2, patients with a pain intensity >= 40 mm on a 100 mm visual analog scale (VAS) and who meet all other eligibility criteria will be admitted into a 3-week, open-label, run-in period during which time they will receive tramadol ER 100 mg once daily (QD) for at least 3 days. On Day 4, the dose will be increased to tramadol ER 200 mg QD, based on tolerability. Patients must be maintained on a minimum dose of tramadol 200 mg QD by the beginning of Week-2 (Visit 3); the dose may be increased to tramadol ER 300 mg QD at Visit 3, based on tolerability. Patients must increase their tramadol ER dose to 300 QD by the beginning of Week - 1 (Visit 4); this dose must be maintained for one week. Patients with pain unresponsive to appropriate dose adjustments or with unacceptable side effects will be discontinued from the study and an alternative analgesic therapy will be initiated. Patients receiving tramadol ER 300 mg QD at the end of the run-in period (Visit 5, Week 0) will enter a 12-week, double-blind period during which they will be randomized to receive tramadol ER 300 mg, tramadol ER 200 mg, or placebo QD. No dose adjustments will be permitted during the double-blind period of the study. Patients will return for safety and efficacy evaluations at Weeks 1, 2, 4, 8 and 12 or early termination. Study medication will be discontinued at Week 12 and patients will return after one week for a post-treatment visit (Week 13).

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..
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 1 inclusion and 1 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?
Patient's pain intensity score since the previous visit,using a visual analog scale(VAS) where 0 mm = no pain and 100 mm = extreme pain.. 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.
