Registered outcomes7

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryPain Intensity Numeric Rating Scale (NRS) ScoreWeek 12
Change from baseline in the weekly mean of the daily Numeric Rating Scale (NRS) score assessing average pain intensity related to DPN in the past 24 hours. In the NRS, a participant selects a whole number (0 to 10) that best indicates the intensity of his/her pain, where 0 represents no pain and 10 represents worst pain imaginable.
SecondaryDaily Sleep Interference Scale (DSIS) ScoreWeek 12
Change from baseline in the weekly mean of the Daily Sleep Interference Scale (DSIS) scores. The DSIS asks participants to ''Select the number that best describes how much your pain has interfered with your sleep during the past 24 hours.'' Response options for the DSIS range from 0 (did not interfere with sleep) to 10 (completely interfered with sleep/unable to sleep due to pain).
SecondaryPatient Global Impression of Change (PGI-C)Week 12Number of subjects 'much improved' or 'very much improved' on Patient Global Impression of Change (PGI-C)
SecondaryNumber of Subjects Achieving ≥30% Pain ReductionWeek 12Number of subjects achieving ≥30% pain reduction from baseline in the weekly mean NRS average pain intensity related to DPN
SecondaryNumber of Subjects Achieving ≥50% ReductionWeek 12Number of subjects achieving ≥50% reduction from baseline in the weekly mean NRS average pain intensity related to DPN
SecondaryNorfolk Quality of Life Questionnaire - Diabetic Neuropathy (QOL-DN) ScoreWeek 12
Change from baseline in the Norfolk Quality of Life Questionnaire - Diabetic Neuropathy (QOL-DN) score. The QOL-DN is a 47 item subject reported questionnaire. Scores range from 0-126, and lower scores indicate improved quality of life.
SecondaryUse of Rescue MedicationWeek 12Number of subjects using rescue medication
