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

PLACEBO COMPARATORInterventions
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).
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.
