Name	Time	Method
Change From Baseline at Week 8 in the Numeric Pain Rating Scale (NPRS) Score	Week 8	Change from baseline in the Numeric Pain Rating Scale (NPRS) score, which is recorded within 15 minutes after stepping out of bed in the morning and averaged over 5 days (defined as 4 days prior to study visit and on the study visit day), at Week 8.

Secondary Outcome Measures

Name	Time	Method
Proportion of Subjects With a Decrease From Baseline of >= 20% in NPRS	Week 8	For the proportion of subjects with a decrease from baseline of \>= 20% in NPRS score at Week 8
Change From Baseline at Week 8 in Foot Function Index (FFI)	Week 8	The Foot Function Index (FFI) is a 23 item questionnaire divided into 3 subscales measuring pain, disability, and activity restriction. The scale was scored from 0 (no pain) to 10 (worst pain imaginable). Both total and sub-scale scores are produced. The total FFI equals the average of the 3 subscale scores. Pain, disability, and activity limitation subscale scores were normalized and the range is from 0 to 100. The total FFI equals the average of the 3 subscale scores. Pain, disability, and activity limitation subscale scores range from 0 to 100.
