NCT00736853

Brief Summary

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).

Outcome Measures

Primary Outcomes (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.

    Day 28 of double-blind period

Secondary Outcomes (22)

  • 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

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

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

    Day 1 and Day 28 of double-blind period

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

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

  • Mean PI Score During Double-Blind Period

    Pre-dose and post-dose at 2 hours, 4 hours on Day 1, 8, 15, 22 and 28 of double-blind period

  • Mean Pain Intensity Difference (PID) During the Open-Label Period

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

  • +17 more secondary outcomes

Interventions

Fixed dose combination of tramadol 37.5 milligram (mg)/acetaminophen 325 mg, 1 or 2 tablets 4 times daily will be given for one week; dose level will be fixed for each participant during the second week based on analgesic efficacy and tolerability (maximum daily dose will be 8 tablets).

Tramadol Hydrochloride Plus Acetaminophen (Open-Label)

Fixed dose combination of tramadol 37.5 mg/acetaminophen 325 mg, 1 or 2 tablets (same dose \[number of tablets\] as that for the second week in the open-label period) will be given 4 times daily up to 4 weeks.

Tramadol Hydrochloride Plus Acetaminophen (Double Blind)

Matching placebo will be given up to 4 weeks.
