Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: A Double Blind, Randomized, Placebo-controlled, Parallel Group Study, for the Assessment of Efficacy, Safety and Tolerability of Brivaracetam at the Doses of 200 mg/Day and 400 mg/Day, in Subjects (at

Brief Summary: Study will assess efficacy, safety and tolerability of brivaracetam in post-herpetic neuralgia (PHN). Duration of 7 weeks divided into 3 periods with no up-titration, nor down-titration.

Sponsor: UCB Pharma

Current Primary Outcome: Percentage change in average pain intensity score (11-point Likert scale) from baseline to the last week of the 4-week treatment period [ Time Frame: Baseline, last week of the 4-week treatment period ]

Percentage change in average pain intensity score (11-point Likert scale) from baseline to the last week of the 4-week treatment period


Original Primary Outcome: To evaluate the reduction in the average pain intensity score on an 11-point numerical pain rating scale from the Baseline Period to the last week of the Treatment Period (4 weeks).

Current Secondary Outcome:

  • 30% responder rate based on percent change in average pain intensity score (11-point Likert scale) from baseline to the last week of the 4-week treatment period [ Time Frame: Last week of the 4-week treatment period ]
    30% responder rate based on percent change in average pain intensity score (11-point Likert scale) from baseline to the last week of the 4-week treatment period
  • Percentage change in sleep interference score (11-point Likert scale) from baseline to the last week of the 4-week treatment period [ Time Frame: Baseline, last week of the 4-week treatment period ]
    Percentage change in sleep interference score (11-point Likert scale) from baseline to the last week of the 4-week treatment period
  • Absolute change in total pain score based on the Short-Form McGill Pain Questionnaire (SF-MPQ) from baseline to last assessment during the 4-week treatment period [ Time Frame: Baseline, last assessment during the 4-week treatment period ]
    Absolute change in total pain score based on the Short-Form McGill Pain Questionnaire (SF-MPQ) from baseline to last assessment during the 4-week treatment period
  • Patient's Global Evaluation Scale (GES) at the end of the 4-week treatment period [ Time Frame: Last assessment during the 4-week treatment period ]
    Patient's Global Evaluation Scale (GES) at the end of the 4-week treatment period
  • Investigator's Global Evaluation Scale (GES) at the end of the 4-week treatment period [ Time Frame: Last assessment during the 4-week treatment period ]
    Investigator's Global Evaluation Scale (GES) at the end of the 4-week treatment period
  • Percent change in brush evoked allodynia intensity (11-point Likert scale) from baseline to the end of the 4-week treatment period [ Time Frame: Baseline, last assessment during the 4-week treatment period ]
    Percent change in brush evoked allodynia intensity (11-point Likert scale) from baseline to the end of the 4-week treatment period
  • Percentage change in brush evoked allodynia surface area (body, face) from baseline to the end of the 4-week treatment period [ Time Frame: Baseline, last assessment during the 4-week treatment period ]
    Percentage change in brush evoked allodynia surface area (body, face) from baseline to the end of the 4-week treatment period


Original Secondary Outcome:

  • o Change in the Sleep Interference Score (11-point numerical sleep interference rating scale from the Baseline Period to the last week of the Treatment Period (4 weeks).
  • o Absolute change from the Randomization visit to the Evaluation/Early Discontinuation visit, in each score of the SF-MPQ.
  • o Reduction in the brush-evoked allodynia intensity and area from the Randomization Visit to the Evaluation/Early Discontinuation visit (4 weeks).
  • o Safety and tolerability of Brivaracetam in PHN.
