    Outcomes

    Primary Outcome Measures

    Change From Baseline to 12 Weeks in the Weekly Mean of the 24-Hour Average Pain Score on the 11-Point Numeric Rating Scale (NRS)
    11-point NRS measures the severity of pain over the previous 24 hours. Participants were asked to provide 24-hour average pain scores in the daily Participant diary and among these, the weekly mean of the 24-hour average pain score was calculated. Scores range from 0 (no pain) to 10 (pain as bad as you can imagine). Mixed Model Repeated Measures (MMRM) model with baseline value, Duration of diabetic peripheral neuropathic pain (DPNP), treatment, week, treatment-by-week interaction as fixed effects was used to produce Least Square Mean (LS Mean).

    Secondary Outcome Measures

    Patient Global Impression of Improvement (PGI-I) at 12 Weeks
    PGI-I assessments was completed by the participant. The participant records how he/she perceives the degree of improvement (or worsening) at the time of assessment since taking treatment. The score ranges from 1 (very much better) to 7 (very much worse). MMRM model with duration of DPNP, treatment, visit, treatment-by-visit interaction as fixed effects was used to produce LS Mean.
    Change From Baseline to 12 Weeks on the Brief Pain Inventory-Severity and Interference Rating Short Form (BPI-SF)
    Brief Pain Inventory Severity and Interference Scores: BPI-S and BPI-I are self-reported scales measuring severity of pain and interference on function. Severity scores: 0 (no pain) to 10 (pain as bad as you can imagine) on each question assessing worst pain, least pain, and average pain in past 24 hours, and pain right now. Interference scores: 0 (does not interfere) to 10 (completely interferes) on each question assessing interference of pain in past 24 hours for general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life. Average interference = average of non-missing scores of individual interference items. MMRM model with baseline, duration of DPNP, treatment, visit, treatment-by-visit interaction as fixed effects was used to produce LS mean.
    Change From Baseline to 12 Weeks on the Neuropathic Pain Symptom Inventory (NPSI)
    NPSI questionnaire is a 12-item self-administered questionnaire that will be completed by the participant. It assesses 5 different dimensions of neuropathic pain on a scale of 0 (no symptom) to 10 (worst imaginable symptom): burning spontaneous pain, pressing spontaneous pain, paroxysmal pain, evoked pain, and paresthesias/dysesthesias. The NPSI includes 12 items: 10 descriptors of the different symptoms and 2 items for assessing the duration of spontaneous ongoing and paroxysmal pain. A total score can be calculated as the sum of the scores of the 10 descriptors with scale range: 0 (no pain) -100 (worst pain imaginable). Analysis of Covariance (ANCOVA) model with last observation carried forward (LOCF) with baseline, treatment, and duration of DPNP as fixed effects was used to produce LS mean.
    Clinical Global Impression of Improvement (CGI-I) at 12 Weeks
    CGI-I measures clinician's perception of participant improvement at the time of assessment (compared with the start of treatment) with scores ranging from 1 (very much better) to 7 (very much worse). MMRM model with duration of DPNP, treatment, visit and treatment-by-visit interaction as fixed effects was used to produce LS Mean.
    Change From Baseline to 12 Weeks on the EuroQol 5 Dimension (EQ-5D)
    The EQ-5D is a self-reported, 5-item scale used to assess the patient's health utility (mobility, self-care, usual activities, pain and discomfort, and depression/anxiety). Scoring is on a 3-point scale.These combinations of attributes were converted into a weighted health-state Index Score according to the Japan population-based algorithm (range of the Index score is -0.111 - 1).A higher score indicates better health state. ANCOVA model with LOCF with baseline value, treatment and duration of DPNP as fixed effects was used to produce LS mean.
    Change From Baseline to 12 Weeks on the Beck Depression Inventory-II (BDI-II) Total Score
    Beck Depression Inventory-II: BDI-II is a 21-item, participant-completed questionnaire to assess characteristics of depression. Each of the 21 items corresponding to symptoms of depression were scored on a 4-point scale ranging from 0 to 3 and was summed to give a single score. A total score of 0-13 was considered minimal range, 14-19 was mild, 20-28 was moderate, and 29-63 was severe. MMRM model with baseline value, duration of DPNP, treatment, visit and treatment-by-visit interaction as fixed effects was used to produce LS mean.
    Change From Baseline to 12 Weeks in the Weekly Mean of Night Pain Scores on the 11-Point NRS
    Night pain severity scores were recorded on an 11-point NRS in the daily patient diary, ranging from 0 (no pain) to 10 (pain as bad as you can imagine).The weekly mean of the night pain score was calculated based on the daily pain score. MMRM model with baseline value, treatment, week, duration of DPNP and treatment-by-week interaction as fixed effects was used to produce LS mean.
    Change From Baseline to 12 Weeks in the Weekly Mean of the 24-Hour Worst Pain Scores on the 11-Point NRS
    24-hour worst pain severity scores were recorded on an 11-point NRS in the daily patient diary, ranging from 0 (no pain) to 10 (pain as bad as you can imagine).The weekly mean of the worst pain score was calculated based on the daily score. MMRM model with baseline value, duration of DPNP, treatment, week, treatment-by-week interaction as fixed effects was used to produce LS mean.
    Number of Participants With a 30% and 50% Reduction in the Weekly Mean of the 24-Hour Average Pain Score on the 11-Point NRS at 12 Weeks
    11-point NRS measures the severity of pain over the previous 24 hours. Patients were asked to provide 24-hour average pain scores in the daily patient diary. scores range from 0 (no pain) to 10 (pain as bad as you can imagine) and among these, the weekly mean of the 24-hour average pain score was calculated based on daily score.
