Treatment of Patients With Diabetic Peripheral Neuropathic Pain in China: Duloxetine Versus Placebo
The purpose of this trial is to assess the efficacy of duloxetine 60 milligrams (mg) once daily (QD) compared with placebo, on the change in pain severity from baseline to 12 weeks as measured by the weekly mean of the daily pain scores recorded in the participant's diary in participants with diabetic peripheral neuropathic pain.

Mean Change From Baseline at 12-Week Endpoint in the Weekly Mean of Pain Severity Score
Aikaikkuna: Baseline, 12 weeks
|
24-hour average pain severity scores were recorded daily by the participant on an 11-point Likert scale, an ordinal scale, with scores ranging from 0 (no pain) to 10 (worst possible pain).
The weekly mean was calculated.
A negative change indicated an improvement in participant's condition.
Least squares (LS) mean was calculated using mixed model repeating measures (MMRM) and adjusted for treatment, pooled investigator, visit, and treatment-by-visit interaction, as well as baseline score and baseline score-by-visit interaction.

Mean Change From Baseline at 12-Week Endpoint in the BPI-Severity Scale
Aikaikkuna: Baseline, 12 weeks
|
BPI-Severity Scale was a self-reported scale that measured the severity of pain based on the average pain over the past 24-hours.
The severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine).
A negative change indicated an improvement in the participant's condition.
LS mean was calculated using MMRM and adjusted for treatment, pooled investigator, visit, and treatment-by-visit interaction, as well as baseline score and baseline score-by-visit interaction.

Mean Change From Baseline at 12-Week Endpoint in the CGI-S Scale
Aikaikkuna: Baseline, 12 weeks
|
CGI-S was administered by the investigator in the presence of the participant and measured the severity of illness at the time of assessment compared with start of treatment; CGI-S scores ranged from 1 (normal, not at all ill) to 7 (among the most extremely ill participants).
A negative change indicated an improvement in the participant's condition.
LS mean was calculated using MMRM and adjusted for treatment, pooled investigator, visit, and treatment-by-visit interaction, as well as baseline score and baseline score-by-visit interaction.

Patient Global Impression of Improvement (PGI-I) Scale at 12-Week Endpoint
Aikaikkuna: 12 weeks

PGI-I was self-reported and measured a participant's perception of improvement at the time of assessment compared with the start of treatment.
Scores ranged from 1 (very much better) to 7 (very much worse).

Mean Change From Baseline at 12-Week Endpoint in the Sensory Subscale of the SF-MPQ
Aikaikkuna: Baseline, 12 weeks
|
SF-MPQ was a self-reported instrument that consisted of 11 sensory descriptors describing pain.
The descriptors were rated on an intensity scale from 0 (none), 1 (mild), 2 (moderate) or 3 (severe).
Three (3) pain scores were derived from the sum of the intensity rank values of the words chosen for sensory descriptors.
The SF-MPQ sensory subscale was the sum of the 11 scores (ranged from 0 to 33, with 33 being the worst pain).
A negative change indicates an improvement.
LS mean was calculated using analysis of covariance (ANCOVA) adjusted for treatment, pooled investigator and baseline.

|
24-hour self-assessment of average daily pain was recorded in the participants diary based on an 11 point Likert scale with scores ranging from 0 (no pain) to 10 (worst possible pain).
Percentage of participants was calculated as: (number of participants with 30% [or 50% or 75%] reduction in average daily pain) divided by (number of participants) multiplied by 100.

|
BPI-Interference Score was a self-reported scale that measured the interference of pain based on the average of the 7 questions assessing the interference of pain for general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life.
The average interference scores ranged from 0 (does not interfere) to 10 (completely interferes).
A negative change indicates an improvement in the participant's condition.
LS means was calculated using MMRM and adjusted treatment, pooled investigator, visit, and treatment-by-visit interaction, baseline score and baseline score-by-visit interaction.

SDS was self-reported and used to assess the effect of the participant's symptoms on their work (Item 1), social life (Item 2), and family life (Item 3).
Each item was measured on a 0 (not at all) to 10 (extremely) point scale with higher values indicating greater disruption.
SDS total score was the sum of the 3 items and ranged from 0 to 30, with higher values indicating greater disruption in the participant's work/social/family life.
Scores ≥5 were associated with significant functional impairment.
A negative change indicated an improvement in the participant's condition.
