Primary Outcome Measures
NameTimeMethod
Change in Pain Intensity for Overall Pain From Pre-treatment Baseline3, 6 and 12-Months

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).

Percentage of Subjects With at Least 50% Pain ReductionBaseline and End of Trial Visit

Percent of subjects with at least a 50% reduction from the baseline pain VAS to the end of trial period VAS. The Visual Analog Scale (VAS) is self-administered instrument assessing average pain intensity. Subjects rated their pain on a horizontal line, 100 mm in length, anchored by word descriptors on each end (no pain to worst imaginable pain). A higher score indicates a higher pain level.
