Outcome Measures

Primary Outcomes (1)

  • Average Diabetic Peripheral Neuropathy (DPN) Pain Based on a Numeric Rating Scale (NRS) Over the Last 7 Days of Each Treatment Period (Week 6 of Each Treatment Period)

    The daily pain diary consisted of an 11-point numeric scale ranging from 0 ("no pain") to 10 ("worst possible pain"). Participants described their pain during the past 24 hours by having chosen the appropriate number between 0 and 10. Self assessment was performed daily in the evening before bedtime on a telephone via interactive voice recognition system (IVRS) (time window for completion between 6.00 pm to midnight). The endpoint mean pain score was defined as the mean of the last 7 daily diary pain ratings while taking study drug in each treatment period - period 1 and period 2, respectively. A rating of 1 - 3 was considered as mild pain; 4 - 6 as moderate pain; and 7 - 10 as severe pain.

    End of Period (includes both Visits 5 and 9)

Secondary Outcomes (22)

  • Percentage of Participants Achieving 30% Reduction in Mean DPN Pain Score From Baseline at the End of Each Treatment Period (Week 6 of Each Treatment Period)

    End of Period (includes both Visits 5 and 9)

  • Percentage of Participants Achieving 50% Reduction in Mean DPN Pain Score From Baseline at the End of Each Treatment Period (Week 6 of Each Treatment Period)

    End of Period (includes both Visits 5 and 9)

  • Brief Pain Inventory-Short Form (BPI-sf) Score for Pain-Severity Domain at the End of Each Treatment Period (Week 6 of Each Treatment Period)

    End of Period (includes both Visits 5 and 9)

  • BPI-sf Score for Pain-Interference Domain at the End of Each Treatment Period (Week 6 of Each Treatment Period)

    End of Period (includes both Visits 5 and 9)

  • Mean Sleep Interference Rating Score at the End of Each Treatment Period (Week 6 of Each Treatment Period)

    End of Period (includes both Visits 5 and 9)

  • +17 more secondary outcomes
