| Primary | Change From Baseline in Mean Pain Score at Endpoint (up to Week 16) | Baseline, Endpoint (up to Week 16) | Mean pain score was defined as the mean of the last 7 daily diary pain ratings. Participants rated their Human Immunodeficiency Virus (HIV) neuropathy pain over the past 24 hours on an 11-point numeric rating scale ranging from 0 = no pain to 10 = worst possible pain. A rating of 1-3 was considered as mild pain; 4-6 = moderate pain; and 7-10 = severe pain. Endpoint was the last observation for a participant assessed using specified imputation method, modified Baseline Observation Carried Forward (mBOCF). |
| Secondary | Number of Participants With Categorical Scores on Patient Global Impression of Change (PGIC) | Week 16 | PGIC: participant rated instrument to measure participant's change in overall status on a 7-point scale; range from 1 (very much improved) to 7 (very much worse). Number of participants in each category is reported. |
| Secondary | Number of Participants With Categorical Scores on Clinician Global Impression of Change (CGIC) | Week 16 | The CGIC scale measures a physician's global impression of a participant's clinical condition at final visit in terms of change relative to the start of treatment (CGIC). At final visit, the participants CGIC will be categorized into a three point scale as: improvement: CGI response of very much improved, much improved or minimally improved; no change: CGI response of no change; worsening: CGI response of very much worse, much worse or minimally worse. Number of participants in each category is reported. |
