- Type
- SECONDARY
- Title
- Stage II: Percentage of Subjects Reaching Minimal Pain on Pin Prick Test (PPT) (≤2 on Numerical Rating Scale Pain Scale)
- Description
Response is defined as a subject having a PPT average pain score of ≤2 recorded at any single time point where PPT was performed. PPT scores were assessed using a 0 (no pain) to 10 (severe pain) Numerical Rating Scale at a frequency of every 1 minute for the first 5 minutes and then every 5 minutes thereafter until the final 60 minute time point.~Stage II outcome.
