干预措施: Placebo (Drug)
结局指标
主要结局
mTCNS total score change from baseline at week 24
时间窗: Baseline and week 24
Changes in Modified Toronto Clinical Neuropathy Score (mTCNS) total score from baseline at Week 24. Maximum mTCNS is 33, minimum is 0. And higher points mean more serious condition. However, more points drop from baseline mean a better outcome.
次要结局
- mTCNS total score change from baseline at week 12(Baseline and week 12)
- Changes in each item score of mTCNS from baseline at week 12 and week 24(Baseline, Weeks 12 and 24)
- TCNS total score change from baseline at week 12 and week 24(Baseline, Weeks 12 and 24)
- Numeric Rating Scale (NRS) score change from baseline at week 24(Baseline and week 24)
- Changes in Nerve Conduction Velocity (NCV) from baseline at week 24(Baseline and week 24)
- Changes in Nerve Conduction Amplitude from baseline at week 24(Baseline and week 24)
