About this study
Official title: A Comparison of Tramadol/Acetaminophen Tablets Maintenance Versus NSAID Maintenance After Tramadol/Acetaminophen and NSAID Combination Therapy in Knee Osteoarthritis Patients: Multicenter, Randomized, Open Comparative Study
The purpose of this study is to compare the effectiveness of tramadol hydrochloride 37.5 milligram (mg) plus acetaminophen 325 mg maintenance with that of non-steroidal anti-inflammatory drugs (NSAIDs) maintenance in participants with knee osteoarthritis (a progressive and degenerative joint disease, in which the joints become painful and stiff) whose pain was relieved after the add-on treatment of tramadol hydrochloride to NSAIDs.
Read the detailed description
This is a multicenter (when more than one hospital or medical school team work on a medical research study), randomized (the study drug is assigned by chance), open-label (all people know the identity of the intervention), comparative study to compare the efficacy of tramadol hydrochloride plus acetaminophen maintenance with that of NSAIDs maintenance in participants whose pain was relieved after the add-on treatment of tramadol 37.5 milligram (mg) plus acetaminophen 325 mg to NSAIDs. All participants will receive tramadol hydrochloride 37.5 mg plus acetaminophen 325 mg, 1 to 3 tablets per day along with NSAIDs (meloxicam [7.5 mg or 15 mg once daily] or aceclofenac [100 mg twice daily]) from Day 1 to Day 28, and participants will be randomly assigned into 2 treatment groups at Day 29 if the numerical rating scale score less than or equal 4. Tramadol plus acetaminophen group will receive 1 or 2 tablets containing tramadol 37.5 mg plus acetaminophen 325 mg 4 times daily (maximum daily dose will be 8 tablets) from Day 29 to Day 85 and NSAIDs group will receive either meloxicam 7.5 mg or 15 mg per day or aceclofenac 100 mg twice a day from Day 29 to Day 85. The efficacy will be evaluated on Day 1, Day 29, Day 57 and Day 85. The primary efficacy end point will be assessed through change in Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) total score from Day 29 to Day 85. Participant's safety will be monitored throughout the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Day 29 in Western Ontario and McMaster Universities Arthritis Index (WOMAC) Total Score at Day 85
The WOMAC is a self-administered and health status questionnaire designed to capture elements of pain, stiffness and physical impairment in participants with osteoarthritis. It consists of 24 questions (5 questions about pain, 2 about stiffness and 17 about physical function) scored on a visual analog scale (VAS) of 0 to 10 cm (0 cm=no pain to 10 cm=worse pain). Individual question responses are assigned a score between 0=extreme and 4=none. Maximum scores for each element differ and therefore, scores were normalized. Total normalized score ranges from 0=worst to 100=best.
Measured: Day 29 and Day 85
Secondary outcomes (6)
Change From Day 29 in Pain Intensity Score at Day 85
Pain intensity was evaluated by 11- point numeric rating scale ranging from 0 to 10 where, 0=no pain and 10=pain as bad as you can imagine.
Measured: Day 29 and Day 85
Number of Participants With Pain Relief
Pain relief was assessed by using a 6-point scale ranging from -1 to 4 where, -1=pain aggravated, 0=no change, 1=slightly relieved, 2=moderately relieved, 3=considerably relieved, and 4=pain completely disappeared. Participants with pain slightly relieved, moderately relieved and completely disappeared were considered as pain relieved.
Measured: Day 29, Day 57 and Day 85
Number of Participants With Overall Assessment on Study Drug by Participants
Participants' overall assessment on study drug was done by using a 5-point scale ranging from -2 to 2 where, -2= very bad, 1= bad, 0=moderate, 1=good and 2=very good. Study drug refers specifically to the randomized treatment received from Day 29 to Day 85.
Measured: Day 85
Number of Participants With Overall Assessment on Study Drug by Investigator
Investigator was completed overall assessment on study drug by using a 5-point scale (-2 to 2; where, -2= very bad, 1= bad, 0=moderate, 1=good and 2=very good). Study drug refers specifically to the randomized treatment received from Day 29 to Day 85.
Measured: Day 85
Number of Participants With Categorical Swelling
Swelling was assessed by using a 4-point scale ranging from 0 to 3 where, 0=no swelling, 1=presence of cross fluctuation of fluid (PCFF), 2=patellar ballotment, and 3=swelling that distort the joint contours (SDJC).
Measured: Day 29, Day 57 and Day 85
Number of Participants With Categorical Tenderness
Tenderness was assessed by using a 4-point scale 0 to 3 where, 0= no tenderness, 1= complaint of tenderness, 2=complaint of tenderness with wincing (CTW), and 3=wincing and attempt to withdraw.
Measured: Day 29, Day 57 and Day 85

The WOMAC is a self-administered and health status questionnaire designed to capture elements of pain, stiffness and physical impairment in participants with osteoarthritis. It consists of 24 questions (5 questions about pain, 2 about stiffness and 17 about physical function) scored on a visual analog scale (VAS) of 0 to 10 cm (0 cm=no pain to 10 cm=worse pain).

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Meloxicam, Aceclofenac and Tramadol Hydrochloride Plus Acetaminophen in people with Osteoarthritis, run by Janssen Korea, Ltd., Korea.
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 5 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 22 Jul 2013. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 24 Jun 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Change From Day 29 in Western Ontario and McMaster Universities Arthritis Index (WOMAC) Total Score at Day 85 (time frame: Day 29 and Day 85). 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 22 Jul 2013.
