About this study
Official title: Tolerability Improvement of Tramadol/Acetaminophen (Ultracet) by Titration in Korean OA Patients:Multicenter, Randomized, Double-blind Study
The purpose of this study is to compare the number of osteoarthritis patients receiving titrated or increasing doses of tramadol hydrochloride/acetaminophen combination tablet (titration group) who discontinue treatment due to adverse events to the number of patients receiving a non-titrated dose of tramadol/hydrochloride/acetaminophen combination tablet who discontinue treatment due to adverse events.
Read the detailed description
This is a randomized (study drug assigned by chance), multicenter, double-blind (neither physician nor patient knows the name of the assigned drug), add-on study (NSAIDs or COX-2 medications maintained at pre-study dose.) to investigate the tolerability of titrated doses of tramadol hydrochloride/acetaminophen combination tablet in osteoarthritis patients taking NSAIDS or COX-2 inhibitors (both are drugs used to treat inflammation and pain) compared to non-titrated doses of tramadol hydrochloride/acetaminophen combination tablet. The patients will be randomized into 2 treatment groups. First group (the titration group) receives 1 tablet of tramadol hydrochloride/acetaminophen in the morning, 1 tablet of placebo in the afternoon and evening for 3 days, then 1 tablet of tramadol hydrochloride/acetaminophen in the morning, 1 tablet of placebo in the afternoon and 1 tablet of tramadol hydrochloride/acetaminophen in the evening for 4 days, and the 1 tablet of tramadol hydrochloride/acetaminophen three times daily for next 7 days. The second group (non-titration group) will receive 1 tablet of tramadol hydrochloride/acetaminophen three times daily without titration for 14 days. The study hypothesis is the first group's discontinuation rate due to adverse events is lower than that of second group. Safety assessments include adverse event, vital sign and clinical lab monitoring. First group will receive 1 tablet of tramadol hydrochloride/acetaminophen and 2 tablets of placebo for 3 days, 2 tablets of tramadol hydrochloride/acetaminophen and 1 tablet of placebo for 4 days, and 3 tablets of tramadol hydrochloride/acetaminophen for 7 days. Second group will receive 3 tablets of tramadol hydrochloride/acetaminophen for 14 days.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing tramadol hydrochloride /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 3 inclusion and 3 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 5 Feb 2010. 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?
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?
Study Discontinuation rate due to adverse event (time frame: Throughout the study from start of study drug until final visit, Day 14). 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 5 Feb 2010.
