研究组 & 干预措施
Placebo Gel
Placebo Gel is vehicle without clonidine
干预措施: Placebo Gel (Drug)
Clonidine Topical Gel (ARC-4558)
Clonidine Topical Gel contains 0.1% clonidine hydrochloride
干预措施: Clonidine Topical Gel (ARC-4558) (Drug)
结局指标
主要结局
Change From Baseline to Week 12 in the Average Daily Pain NPRS (Numeric Pain Rating Scale) Score; mLOCF Imputation
时间窗: Baseline (average of Days -7 to -1) and Week 12 (Average of Days 78 to 84)
Pain in the feet was scored daily at bedtime by the subject on a 0-10 numeric pain rating scale (NPRS) through Day 84. Subjects were asked to record average pain in the feet over the past 24 hours. A score of 0 indicated "no pain" and a score of 10 was "worst possible pain". The change in pain is represented as Week 12 minus Baseline, so greater negative numbers represent more improvement (more pain relief).

- Change From Baseline to Week 12 in the Worst Daily Pain NPRS Score; mLOCF Imputation(Baseline (average of Days -7 to -1) and Week 12 (average of Days 78 to 84))
- Change From Baseline in the Brief Pain Inventory Functional Interference Scale at Week 12; mLOCF Imputation(Baseline and Week 12)
- Clinician Global Impression of Change (CGIC) at Week 12(Week 12)
- Change From Baseline in Average Daily Pain NPRS Score for Each Week of Treatment; mLOCF Imputation(Baseline (average of Days -7 to -1) and Weeks 1 through 12 (weekly averages))
