February 6, 2013 updated by: Janssen Pharmaceutica

A Randomized Controlled Trial on the Efficacy, Safety and Quality of Life Effects of Add-on Tramadol/Paracetamol Combination in Chronic Osteoarthritis

The purpose of this study is to evaluate the efficacy, safety and effects on Quality of Life (QOL) of tramadol/paracetamol (APAP) as an add-on therapy (medication taken in addition to another medication) in Filipino participants with chronic (lasting a long time) osteoarthritis (disorder, which is seen mostly in older persons, in which the joints become painful and stiff).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is an open-label (all people know the identity of the intervention), randomized (study drug assigned by chance), controlled study to evaluate the efficacy, safety and effects on QOL of tramadol/APAP as an add-on therapy in Filipino participants suffering from chronic pain because of chronic osteoarthritis. Participants will be randomly assigned to 2 groups: tramadol/APAP group and non tramadol/APAP group. Participants in tramadol/APAP group will receive celecoxib 200 milligram (mg) and fixed dose combination of tramadol (37.5 mg)/APAP (325 mg) as add on therapy, while the participants in non-tramadol/APAP group will receive celecoxib 200 mg only. The total duration of the study will be 4 weeks. The participants in both the groups will be given celecoxib 200 mg once daily for 4 weeks. In addition, the participants in the tramadol/APAP group will be given add-on tramadol/APAP doses 3 times a day for 4 weeks. Participants will be asked to return for follow-up at Weeks 2 and 4. Efficacy will be assessed using 100 millimeter (mm) Visual Analog Scale (VAS) while QOL will be assessed using the Oswestry Disability Index (ODI). Participant safety will be monitored throughout the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Visual Analogue Scale for Pain (VAS-pain) Score at Week 2
Time Frame: Baseline and Week 2
VAS is a 100 millimeter (mm) scale. Intensity of pain range: 0 mm=no pain to 100 mm=worst possible pain. Change=scores at observation minus score at baseline. An increase in score from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented improvement.
Baseline and Week 2
Change From Baseline in VAS-pain Score at Week 4
Time Frame: Baseline and Week 4 Last Observation Carried Forward (LOCF)
VAS is a 100 mm scale. Intensity of pain range: 0 mm=no pain to 100 mm=worst possible pain. Change=scores at observation minus score at Baseline. An increase in score from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented improvement.
Baseline and Week 4 Last Observation Carried Forward (LOCF)
Change From Baseline in Oswestry Disability Index (ODI) Score at Week 2
Time Frame: Baseline and Week 2
The ODI is a low back pain-specific, validated instrument that consists of questions related to limitations in performing specific activities of daily living and 1 question related to pain intensity. The ODI is a self-administered questionnaire that is usually completed in less than 5 minutes. The ODI consists of 10 sections. Each section consists of 6 statements ranked from 0 to 5 (0=good to 5=worse). A higher score represents greater disability.
Baseline and Week 2
Change From Baseline in ODI Score at Week 4
Time Frame: Baseline and Week 4 (LOCF)
The ODI is a low back pain-specific, validated instrument that consists of questions related to limitations in performing specific activities of daily living and 1 question related to pain intensity. The ODI is a self-administered questionnaire that is usually completed in less than 5 minutes. The ODI consists of 10 sections. Each section consists of 6 statements ranked from 0 to 5 (0=good to 5=worse). A higher score represents greater disability.
Baseline and Week 4 (LOCF)
Percentage of Participants Who Discontinued Because of Rescue Medication
Time Frame: Baseline up to Week 4
Rescue medications are medicines that may be administered to the participants when the efficacy of the study drug is not satisfactory, or the effect of the study drug is too great and is likely to cause a hazard to the participant, or to manage an emergency situation.
Baseline up to Week 4
Time to Discontinuation Because of Rescue Medication
Time Frame: Baseline up to Week 4
Rescue medications are medicines that may be administered to the participants when the efficacy of the study drug is not satisfactory, or the effect of the study drug is too great and is likely to cause a hazard to the participant, or to manage an emergency situation.
