Outcome Measures

Primary Outcome Measures

  1. Change From Baseline in Average Daily Pain Numeric Rating Scale (NRS) Score at Week 6 [Baseline, Week 6]

    Participants assessed their average daily pain during the past 24 hours on an 11--point NRS ranging from 0 (no pain) to 10 (worst possible pain) with lower scores indicating less pain. Week 6 score was calculated as the mean of average daily pain NRS scores over the past 7 days. The change from baseline was calculated using difference between Week 6 mean score and Baseline mean score.

Secondary Outcome Measures

  1. Change From Baseline in Average Daily Pain Numeric Rating Scale (NRS) Score at Weeks 1, 2, 4, 8, 12 and 16 [Baseline, Week 1, 2, 4, 8, 12, 16]

    Participants assessed their average daily pain during the past 24 hours on an 11--point NRS ranging from 0 (no pain) to 10 (worst possible pain) with lower scores indicating less pain. Post Baseline weekly scores were calculated as the mean of average daily pain NRS scores over the past 7 days prior to corresponding week visits. The change from baseline was calculated using difference between post baseline weekly mean score and the Baseline mean score.

  2. Change From Baseline in Average Daily Pain Numeric Rating Scale (NRS) Score Over Weeks 1 to 4, 1 to 8, 1 to 12, 1 to 16, 5 to 8, 5 to 12 and 5 to 16 [Baseline, Week 1 to 4, Week 1 to 8, Week 1 to 12, Week 1 to 16, Week 5 to 8, Week 5 to 12, Week 5 to 16]

    Participants assessed their average daily pain during the past 24 hours on an 11-point NRS ranging from 0 (no pain) to 10 (worst possible pain) with lower scores indicating less pain. Scores for each time interval over the weeks were calculated from the mean of daily pain score of participants over that specified duration. Change from baseline was calculated as the average of each specified week interval (Week 1 to 4, 1 to 8, 1 to 12, 5 to 8, 5 to 12 and 5 to 16) values minus the baseline value.

  3. Change From Baseline in Modified Brief Pain Inventory-Short Form (mBPI-sf) Scale Score for Worst Pain, Average Pain and Pain Severity at Weeks 1, 2, 4, 6, 8 ,12 and 16 [Baseline, Weeks 1, 2, 4, 6, 8 ,12, 16]

    mBPI-sf is a self-administered questionnaire (5 questions) to assess pain severity and impact of pain on daily functions. Questions 1 to 4 measure the magnitude of pain (Q1 for worst, Q2 for least, Q3 for average and Q4 for pain right now) on an 11-point NRS ranging from 0 (no pain) to 10 (worst possible pain) with lower scores indicate less pain. Question 5 consists of 7 item subsets which measure the level of interference of pain on daily functions: 1: general activity, 2: mood, 3: walking ability, 4: normal work, 5: relations with other, 6: sleep, 7: enjoyment of life. Each item assessed on an 11-point NRS ranging from 0 (no interference) to 10 (complete interference), where lower scores indicate less interference of pain. Pain severity score was derived from the sum of responses of questions 1-4 and ranged from 0 (no pain) to 40 (worst possible pain) with lower scores indicates less pain. Results are reported for worst pain score, average pain score and pain severity score.

  4. Number of Participants With Mean Average Daily Pain Score of Less Than or Equal to (<=) 2 at Weeks 1, 2, 4, 6, 8, 12 and 16 [Week 1, 2, 4, 6, 8, 12, 16]

Outcome Measures

1. Primary Outcome
Title Change From Baseline in Average Daily Pain Numeric Rating Scale (NRS) Score at Week 6
Description Participants assessed their average daily pain during the past 24 hours on an 11--point NRS ranging from 0 (no pain) to 10 (worst possible pain) with lower scores indicating less pain. Week 6 score was calculated as the mean of average daily pain NRS scores over the past 7 days. The change from baseline was calculated using difference between Week 6 mean score and Baseline mean score.
Time Frame Baseline, Week 6

4. Secondary Outcome
Title Change From Baseline in Modified Brief Pain Inventory-Short Form (mBPI-sf) Scale Score for Worst Pain, Average Pain and Pain Severity at Weeks 1, 2, 4, 6, 8 ,12 and 16
Description mBPI-sf is a self-administered questionnaire (5 questions) to assess pain severity and impact of pain on daily functions. Questions 1 to 4 measure the magnitude of pain (Q1 for worst, Q2 for least, Q3 for average and Q4 for pain right now) on an 11-point NRS ranging from 0 (no pain) to 10 (worst possible pain) with lower scores indicate less pain. Question 5 consists of 7 item subsets which measure the level of interference of pain on daily functions: 1: general activity, 2: mood, 3: walking ability, 4: normal work, 5: relations with other, 6: sleep, 7: enjoyment of life. Each item assessed on an 11-point NRS ranging from 0 (no interference) to 10 (complete interference), where lower scores indicate less interference of pain. Pain severity score was derived from the sum of responses of questions 1-4 and ranged from 0 (no pain) to 40 (worst possible pain) with lower scores indicates less pain. Results are reported for worst pain score, average pain score and pain severity score.

Description mBPI-sf:questionnaire (5 questions) to assess pain severity and impact of pain on daily functions. Questions 1-4 assess magnitude of pain(Q1 for worst, Q2 for least, Q3 for average and Q4 for pain right now) on an 11-point NRS ranging from 0 (no pain) to 10 (worst possible pain) with lower scores indicate less pain. Question 5 consists 7 item subsets which assess level of interference of pain on daily functions: 1: general activity (GA),2: mood, 3: walking ability, 4: normal work (NW),5: relations with other,6: sleep, 7: enjoyment of life. Each item assessed on an 11-point NRS ranging from 0 (no interference) to 10 (complete interference), where lower scores =less interference of pain. These 7 items were averaged to obtain pain interference composite score (CS), ranging from 0 (no interference) to 10 (complete interference), where lower scores =less interference of pain. Change from baseline in mBPI-sf score for pain interference with CS score, GA subtest and NW subtest were reported.

12. Secondary Outcome
Title Number of Participants With Change From Baseline in Patient's Global Assessment of Pain Score at Weeks 1, 2, 4, 6, 8, 12 and 16
Description Patient's global assessment of pain from post-herpetic neuralgia assessed participant's overall impression of disease activity. Participants answered: "Considering all the ways your pain from post-herpetic neuralgia, how are you doing today?". Participants responded using a 5--point Likert scale with a score of 1 being the best (very good) and a score of 5 being the worst (very poor) with lower scores indicating better condition. Number of participants who reported a change from Baseline of -4, -3, -2, -1, 0, 1, 2, 3, 4 in Patient's Global Assessment of Pain scores at each specified time-point were presented.

Title Change From Baseline in Modified Brief Pain Inventory-Short Form (mBPI-sf) Score for Pain Interference With Sleep at Weeks 1, 2, 4, 6, 8 ,12 and 16
Description mBPI-sf is a self-administered questionnaire (5 questions) to assess pain severity and impact of pain on daily functions. Questions (Q) 1-4 assess magnitude of pain severity (Q1 for worst, Q2 for least, Q3 for average, Q4 for pain right now) on an 11-point NRS ranging from 0 (no pain) to 10 (worst possible pain) with lower scores indicate less pain. Question 5 consists of 7 item subsets which assess the level of interference of pain on daily functions: 1: general activity, 2: mood, 3: walking ability, 4: normal work, 5: relations with other, 6: sleep, 7: enjoyment of life. Each item was assessed on an 11-point NRS ranging from 0 (no interference) to 10 (complete interference), where lower scores indicated less interference of pain. Change from Baseline in mBPI-sf score for pain interference with sleep were reported.

Title Change From Baseline in Hopkins Verbal Learning Test - Revised (HVLT-R) at Week 2, 6, 12, 16 and End of Study
Description HVLT-R was a word-list learning and memory test used to assess the changes in memory. The task was repeated, for a total of 3 learning trials. After a delay interval of 20 to 25 minutes, delayed recall trial was administered. 1)Learning efficiency: Assessed by examining the learning curve over 3 learning trials and by evaluating the sum of the scores for all 3 learning trials. Raw scores for each of the 3 learning trials were summed for the total recall (TR) score. The TR score ranges from 0 to 36, where higher scores indicated greater verbal learning and recall, 2) Ability to access newly learned information: Assessed by the number of words retained on the delayed recall (DR) trial and the percentage of words recalled from the word list. DR trial score ranges from 0 to 12, where higher scores indicated greater verbal learning and recall.
