About this study

Official title: A Phase 3 Study of JNS013 in Patients With Chronic Pain

The purpose of this study is to evaluate the efficacy and safety of tramadol hydrochloride plus acetaminophen (JNS013) in participants with chronic pain accompanied by osteoarthritis (a progressive and degenerative joint disease, in which the joints become painful and stiff) of the knee or low back pain (acute or chronic pain in the lumbar or sacral regions) which cannot be controlled sufficiently with non-steriodal anti-inflammatory drugs (NSAIDs).

Read the detailed description

This is a multi-center (when more than one hospital or medical school team work on a medical research study), double-blind (test or experiment in which neither the person giving the treatment nor the participant knows which treatment the participant is receiving), placebo-controlled (an inactive substance; a pretend treatment [with no drug in it] that is compared in a clinical trial with a drug to test if the drug has a real effect), parallel group comparison study. The total duration of the study will be 11 weeks and consists of 4 periods; a pre-observation period (4 weeks), open-label period (2 weeks), double-blind period (4 weeks) and follow-up period (1 week). Participants will receive tramadol hydrochloride plus acetaminophen tablets orally 4 times daily for 2 weeks with no less than 4-hour intervals (up to 8 tablets per day) during the open-label period and the dose will be fixed for each participant in the latter 1 week. During the double-period participants will receive tramadol hydrochloride plus acetaminophen tablets or placebo at the same dose as used for the latter 1 week of the open-label period for up to 4 weeks. Efficacy will be primarily evaluated by number of participants with insufficient pain relief after the start of double-blind period. 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.

  1. Number of Participants With Insufficient Pain Relief After the Start of Double-Blind Period

    The pain relief was regarded as insufficient, if either of the following was met, a) the value of average pain intensity felt in daily living during the past 24 hours (Visual analog scale 24 [VAS24] ) on 2 consecutive days in double-blind period worsened greater than 15 millimeter (mm) compared with the average VAS24 during 3 days before the end of open-label period, b) when the participant asked for discontinuation of treatment with the study drug because of insufficient pain relief.

    Measured: Day 28 of double-blind period

Secondary outcomes (22)
  1. Change in the Visual Analog Scale for the Last 24 Hours (VAS24) Value at the Start of the Double-Blind Period From the Baseline Value at the Start of the Open-Label Period

    Pain over the last 24 hours was assessed by using VAS score ranges from 0 mm=no pain to 100 mm=worst possible pain. An increase in score from Baseline represented disease progression and decrease represented improvement.

    Measured: Day 1 of open-label period and Day 1 of double-blind period

  2. Change in the VAS24 Value From the Baseline at the Final Time Point of the Double-Blind Period

    Pain over the last 24 hours was assessed by using VAS score ranges from 0 mm=no pain to 100 mm=worst possible pain. An increase in score from Baseline represented disease progression and decrease represented improvement.

    Measured: Day 1 and Day 28 of double-blind period

  3. Mean Pain Intensity (PI) Score During Open-Label Period

    PI was evaluated on a 4-stage scale with a score ranging from 0 to 3, wherein 0=no pain and 3=severe pain.

    Measured: Pre-dose and post-dose at 2 hours, 4 hours on Day 1, and Day 8 of open-label period

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Tramadol Hydrochloride Plus Acetaminophen (Open-Label) and Tramadol Hydrochloride Plus Acetaminophen (Double-Blind) in people with Pain, run by Janssen Pharmaceutical K.K. at 20 sites in Japan.

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 4 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 26 Sep 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 26 Sep 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?

Number of Participants With Insufficient Pain Relief After the Start of Double-Blind Period (time frame: Day 28 of double-blind period). 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 26 Sep 2013.
