"This outcome measure is the mean of the available CMTNS-v2 Examination Score values at month 12 and month 15.~The CMTNS-v2 is a specific scale designed to assess severity of impairment in CMT disease. It is a 36-point scale based on nine items to quantify impairment (sensory symptoms, pin sensibility, vibration and arm and leg strength), activity limitations (motor symptoms arms and legs) and electrophysiological function (amplitudes of ulnar CMAP and SNAP). The CMTNS-v2 goes from 0 (no impairment) to 36 (maximum impairment) whom each sub-items goes from 0 to 4.~The CMTES-v2 is summed of item 1 to 7 of the CMTNS-v2 (limited to impairment items and excluding electrophysiological items). It is a 28-point score: 0 (no impairment) to 28 (maximum impairment).~Lower CMTES-v2 values indicate a better clinical condition.~Reported values are the values at Baseline (Base) and the average of the available values at Month 12 and Month 15 (Fin)."

Overall Neuropathy Limitation Scale (ONLS) Total Score

"The primary efficacy variable used in the main analysis is the mean of the available ONLS values at month 12 and month 15.~The ONLS is a disability scale that was derived and improved from the Overall Disability Sum Score (ODSS) to measure limitations in the everyday activities of the upper limbs (rated on 5 points) and the lower limbs (rated on 7 points). The total score is a 12-point scale: 0 (no disability) to 12 (maximum disability). Lower values in the ONLS indicate a better clinical condition.~Reported values are the values at Baseline (Base) and the average of the available values at Month 12 and Month 15 (Fin)." (NCT02579759)
