Mean Change From Baseline in Patient-Reported Outcomes Measurement Information System Pain Interference Short Form 8a (PROMIS PI SF8a)
Tidsramme: Baseline, Week 12
|
The Patient-Reported Outcomes Measurement Information System Pain Interference Short Form 8a (PROMIS PI SF8a) was administered to measure self-reported consequences of pain on various aspects of the participant's life within the previous 7 days.
The scale consists of 8 items, all measuring a single domain of pain interference, including impact on day-to-day activities, work around the home, household chores, family life, social activities, activities done for fun, enjoyment of social activities, and enjoyment of life.
Each item was rated on a 5-point response scale ranging from "not at all" (1) to "very much" (5); the 8 item scores were summed to produce a raw score ranging from 8 (minimum) to 40 (maximum).
The raw score was then converted to a T-score with a mean of 50 and a standard deviation of 10; higher T-scores indicate worse outcome (greater pain interference).
Range cannot be specified in norm-based scores.

Mean Change From Baseline in Patient-Reported Outcomes Measurement Information System Physical Functioning Short Form 10a (PROMIS PF SF10a)
Tidsramme: Baseline, Week 12
|
The PROMIS PF SF10a was administered to assess self-reported physical function and physical activities across 10 items at the present time.The first 5 items assess current physical limitations (health in doing vigorous activities, walking more than one mile, climbing stairs, lifting or carrying groceries, and bending, kneeling, or stooping), each rated on a 5-point Likert scale ranging from "not at all" to "cannot do".
The remaining 5 items are self-reported ability to perform specific physical activities such as chores,dressing themselves, bathing,sitting on and getting up from the toilet, each rated on a 5-point likert scale ranging from "without any difficulty" to "unable to do".
The 10 item scores were summed to produce a raw score ranging from 10 (minimum) to 50 (maximum).The raw score was then converted to a T-score with a mean of 50 and a standard deviation of 10; higher T-scores indicate better outcome (greater physical function).Range cannot be specified in norm-based scores.

Tidsramme: Baseline, Week 12

The Patient-Reported Outcomes Measurement Information System Sleep Disturbance Short Form 8b (PROMIS SD SF8b) was administered to assess perceptions of sleep quality, sleep depth, and restoration associated with sleep within the previous 7 days, including perceived difficulties and concerns with getting to sleep or staying asleep, and perceptions of the adequacy of and satisfaction with sleep.
The scale consists of 8 items, all measuring a single domain of sleep disturbance.
Each item was rated on a 5-point response scale ranging from "not at all" to "very much," "never" to "always," or "very poor" to "very good"; the 8 item scores were summed to produce a raw score ranging from 8 (minimum) to 40 (maximum).
The raw score was then converted to a T-score with a mean of 50 and a standard deviation of 10; higher T-scores indicate worse outcome (greater sleep disturbance).
Range cannot be specified in norm-based scores.

Mean Change From Baseline in Patient's Global Impression (PGI) of Illness Status as Measured by PGI-Status
Tidsramme: Baseline, Week 12
|
The Patient's Global Impression-Status (PGI-Status) is a patient-reported single-item instrument designed to assess the participant's status with diabetic nerve pain.
Three PGI-Status scales were administered to assess physical activity, usual activity, and sleep disturbance.
For physical activity, participants rated their status at the present time; for usual activity and sleep disturbance, participants rated their overall status over the past week.
Physical activity and usual activity were each rated on a 5-point Likert scale ranging from 1 (minimum, "extremely limited") to 5 (maximum, "not at all limited"); higher scores indicate better outcome (less limitation).
Sleep disturbance was rated on a 5-point Likert scale ranging from 1 (minimum, "very much") to 5 (maximum, "not at all"); higher scores indicate better outcome (less sleep disturbance).

Patient's Global Impression of Change as Measured by Patient's Global Impression-Change (PGI-Change)
Tidsramme: Week 12
|
The Patient's Global Impression-Change (PGI-Change) is a patient-reported single-item instrument designed to assess the participant's rating of change in diabetic nerve pain since they began taking the study medication.
Four PGI-Change scales were administered to assess diabetic nerve pain's impact on physical activities, usual activities, sleep disturbance, and overall change.
Each item was rated on a 5-point Likert scale ranging from 1 (minimum, "much worse") to 5 (maximum, "much better"); higher scores indicate better outcome (greater improvement).

Mean Change From Baseline in Neuropathy Total Symptom Score-6 (NTSS-6)
Tidsramme: Baseline, Week 12
|
The NTSS-6 assessed the frequency and intensity of 6 diabetic peripheral neuropathic symptoms over the previous 7 days: (1) numbness and/or insensitivity, (2) prickling and/or tingling sensation, (3) burning sensation, (4) aching pain and/or tightness, (5) sharp, shooting, lancinating pain, and (6) allodynia and/or hyperalgesia.
Each of the 6 symptoms was rated on two separate response scales: an intensity scale (Does not apply [0], Mild [1], Moderate [2], or Severe [3]) and a frequency scale (Never [0], Occasionally, less than 1/3 of the time [0], Often, 1/3 to 2/3 of the time [0.33], or Almost always, more than 2/3 of the time [0.66]).
The total score was calculated as the weighted sum across all 6 symptoms, where intensity was given a weight of 1 and frequency was given a weight of 1/3, yielding a total score ranging from 0 (minimum, no symptoms) to 21.96 (maximum, most severe); higher scores indicate worse outcome (greater neuropathic symptom burden).
