About this study
Official title: Open-label Assessment of the Safety and Effectiveness of Extended Release Tramadol (Tramadol ER) in the Treatment of Chronic Non-malignant Pain.
The purpose of this study is to assess the safety of tramadol HCl ER following long-term treatment. The study hypothesis is that long-term treatment with tramadol HCl ER is safe and effective for the treatment of chronic, non-malignant 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 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 study is a multicenter, multiple-dose, 1-year open-label study designed to assess the safety and effectiveness of tramadol HCl ER. Patients with moderate to severe chronic non-malignant pain, requiring treatment with an analgesic on a daily basis, are eligible for study participation. Patients eligible for enrollment are as follows: those who completed 12 weeks in one of two prior double-blind studies ("roll-over patients") or those without participation in any prior study of tramadol HCl ER ("direct enrollment patients"). Following a screening evaluation and baseline assessment, roll-over patients will be treated for up to 38 weeks and direct enrollment patients for up to 58 weeks. At baseline (Visit 2), patients will receive tramadol HCl ER 100 mg once daily (QD) for 3 days; on day 4, they will increase to tramadol HCl ER 200 mg QD, based on tolerability. Patients will be required to be on a minimum dose of tramadol HCl ER 200 mg QD by Visit 3. At Visit 4, patients are required to begin treatment with a minimum dose of tramadol HCl ER 300 mg QD. The maximum dose of tramadol HCl ER for patients >= 75 years old is 300 mg QD. By Visit 5, patients < 75 years old are to be initiated on a tramadol HCl ER dose of 400 mg QD. Patients who cannot tolerate a dose increase of tramadol HCl ER from 300 mg or 400 mg QD (due to side effects) or who upon dose increase cannot tolerate the dose will be permitted to reduce the tramadol HCl ER dose to 300 mg QD. Patients unable to tolerate tramadol HCl ER 300 mg or 400 mg QD or those who had pain unresponsive to appropriate dose adjustments will be discontinued and alternate analgesic therapy initiated, as appropriate.

What is being measured
The primary outcome is the main question the study is designed to answer.
The primary outcomes are analyses of adverse events (incidence, frequency,
severity, attribution, adverse events causing withdrawal from study)
Secondary outcomes (3)
The secondary outcomes are pain intensity (visual analog scale) assessment,
patient global assessment of study medication, pain recall (least, worst and
average pain); changes from baseline to each subsequent visit.

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.

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 outcomes are analyses of adverse events (incidence, frequency,. The study lists 2 primary outcomes in all. 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.
