Primary Outcome Measures
NameTimeMethod
mTCNS total score change from baseline at week 24Baseline 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.

Secondary Outcome Measures
NameTimeMethod
mTCNS total score change from baseline at week 12Baseline and week 12

Changes in Modified Toronto Clinical Neuropathy Score (mTCNS) total score from baseline at Week 12. Maximum mTCNS is 33, minimum is 0. And higher points mean more serious condition. However, more points drop from baseline mean a better outcome.

Changes in each item score of mTCNS from baseline at week 12 and week 24Baseline, Weeks 12 and 24

The mTCNS contains the 11 items that assess symptoms and signs, and each item maximum is 3 points, minimum is 0. And higher points mean more serious condition. However, more points drop from baseline mean a better outcome.

TCNS total score change from baseline at week 12 and week 24Baseline, Weeks 12 and 24

Changes in Toronto Clinical Neuropathy Score (TCNS) total score from baseline at Week 12 and Week 24. Maximum TCNS is 19, minimum is 0. And higher points mean more serious condition. However, more points drop from baseline mean a better outcome.

Numeric Rating Scale (NRS) score change from baseline at week 24Baseline and week 24

Changes in Numeric Rating Scale (NRS) score from baseline at Week 24. Maximum NRS is 10, minimum is 0. And higher points mean more serious condition. However, more points drop from baseline mean a better outcome.

Changes in Nerve Conduction Velocity (NCV) from baseline at week 24Baseline and week 24
Changes in Nerve Conduction Amplitude from baseline at week 24Baseline and week 24
