Outcome

Type Measure Description Time frame Safety issue
Primary Change in Pain Intensity for Overall Pain From Pre-treatment Baseline The Visual Analog Scale (VAS) is self-administered instrument assessing average pain intensity. Subjects rated their pain on a horizontal line, 10 cm in length, anchored by word descriptors on each end (no pain to worst imaginable pain). A higher score indicates a higher pain level. The values range from 0 (minimum pain) to 10 (maximum pain). Baseline, 3, 6 and 12 Months
Primary Percentage of Subjects With at Least 50% Pain Reduction Percent of subjects with at least a 50% reduction. The Visual Analog Scale (VAS) is self-administered instrument assessing average pain intensity. Subjects rated their pain on a horizontal line, 10 cm in length, anchored by word descriptors on each end (no pain to worst imaginable pain). A higher score indicates a higher pain level. The values range from 0 (minimum) to 10 (maximum). 3, 6 and 12-Month Visits
