Outcome Measures
Primary Outcome Measures
- Motor Nerve Conduction Velocity (m/Sec) [48 weeks]
Absolute change from baseline at Week 48.
- Distal Latency (Msec) [48 weeks]
Absolute change from baseline at Week 48.
- F Wave Latency (Msec) [48 weeks]
Absolute change from baseline at Week 48.
- Length of Motor Nerve Potential [48 weeks]
Absolute change from baseline at W48.
Secondary Outcome Measures
- ONLS (Overall Neuropathy Limitations Scale) [48 weeks]
The ONLS focuses on upper and lower limb functions, and consists of a checklist for interviewing patients. It is scored from 0 to 5 on the upper limb section and from 0 to 7 on the lower limb section. A score of 0 indicates no limitations (the ceiling of the scale) and a score of 5 or 7 indicates no purposeful movement. Absolute change from baseline at week 48.
- Change From Baseline at Week 48 for Timed 10-meter Walk Test [48 weeks]
Absolute change from baseline at week 48. The patient is instructed to walk at normal pace for 10 meters. Start and stop of performance time coincides with the toes of the leading foot crossing the 2-m mark and the 8-m mark, respectively. From these data, the speed may be calculated by dividing the middle 6 m by the time (in seconds).
- Absolute Change From Baseline at Week 48 for Medical Research Council (MRC) Subscore (Total Muscle) and Total Score [48 weeks]
MRC score assessed in 19 muscles. The muscle scale grades muscle power on a scale of 0 to 5 in relation to the maximum expected for that muscle. The patient's effort is graded on a scale of 0-5: Grade 5: Muscle contracts normally against full resistance. Grade 4: Muscle strength is reduced but muscle contraction can still move joint against resistance. Grade 3: Muscle strength is further reduced such that the joint can be moved only against gravity with the examiner's resistance completely removed. As an example, the elbow can be moved from full extension to full flexion starting with the arm hanging down at the side. Grade 2: Muscle can move only if the resistance of gravity is removed. As an example, the elbow can be fully flexed only if the arm is maintained in a horizontal plane. Grade 1: Only a trace or flicker of movement is seen or felt in the muscle or fasciculations are observed in the muscle. Grade 0: No movement is observed.
- INCAT Sensory Sum Score (ISS) [48 weeks]
This sensory scale comprises pin prick and vibration sense plus a two point discrimination value in the arms and legs, and ranges from 0 ("normal sensation") to 20 ("most severe sensory deficit"). Absolute change from baseline at week 48.
- 6-minute Walk Test [48 weeks]
The 6MWT is a practical simple test that requires a 30 m (100-ft) hallway. This test measures the distance that a patient can quickly walk on a flat, hard surface in a period of 6 minutes. Absolute change from baseline at week 48.
- Posturography Score [48 weeks]
Computerized dynamic posturography (CDP) is a non-invasive specialized clinical assessment technique used to quantify the central nervous system adaptive mechanisms (sensory, motor and central) involved in the control of posture and balance, both in normal and abnormal conditions. Absolute change of speed in spontaneous speed condition from baseline at week 48.
- Excitability Testing: Supernormality (%) [48 weeks]
Nerve excitability testing is a non-invasive approach in investigating the pathophysiology of peripheral nerve disorders, which determines the electrical properties of the nerve membrane at the site of stimulation. Absolute change from baseline at week 48. After a nerve fiber is depolarized, a sequence of excitability changes, called the 'recovery cycle', occurs before the membrane potential returns to its resting stage. This cycle includes phases in which the nerve excitability is decreased ('refractory period' or increased ('supernormal period'). During the 10-30 ms following the end of the refractory period, the axon increases its excitability and the nerve fiber is more easily excited (the supernormal period). Depolarization of the node of Ranvier excites the adjacent internodes, which then charge with electric current as capacitors. Supernormality depends on many factors and its interpretation is therefore not univoqual. Data were provided for information only.
- Strength-duration Time Constant (ms) [48 weeks]
This secondary outcome measure is an electrophysiological testing endpoint. Absolute change from baseline at week 48. Strength-duration Time Constant (ms) is a measurement of excitability, defined as the duration of the stimulus that has twice the strength of the rheobase current (see below). The lower the rheobase is, the higher is the Strenght duration time constant. Accordingly, higer values of SDTC are associated with better outcome.
- Rheobase (mA) [48 weeks]
This secondary outcome measure is an electrophysiological testing endpoint. Absolute change from baseline at week 48. Rheobase is the minimal strength of an electrical stimulus of infinitely long duration that is able to cause excitation. Low values are associated with better outcome (the nerve becomes more excitable).
- Refractoriness (%) [48 weeks]
This secondary outcome measure is an electrophysiological testing endpoint. Absolute change from baseline to week 48. After a nerve fiber is depolarized, a sequence of excitability changes, called the 'recovery cycle', occurs before the membrane potential returns to its resting stage. This cycle includes phases in which the nerve excitability is decreased ('refractory period' or increased ('supernormal period'). Refractoriness depends on many factors and its interpretation is therefore not univoqual. Data were provided for information only.
- Minimum Absolute Refractory Period (ms). [48 weeks]
This secondary outcome measure is an electrophysiological testing endpoint. Absolute change from baseline at week 48. After a nerve fiber is depolarized, a sequence of excitability changes, called the 'recovery cycle', occurs before the membrane potential returns to its resting stage. This cycle includes phases in which the nerve excitability is decreased ('refractory period' or increased ('supernormal period'). Refractoriness depends on many factors and its interpretation is therefore not univoqual. Data were provided for information only.
- Maximum Absolute Refractory Period (ms). [Week 48]
This secondary outcome measure is an electrophysiological testing endpoint. Absolute change from baseline at week 48. After a nerve fiber is depolarized, a sequence of excitability changes, called the 'recovery cycle', occurs before the membrane potential returns to its resting stage. This cycle includes phases in which the nerve excitability is decreased ('refractory period' or increased ('supernormal period'). Refractoriness depends on many factors and its interpretation is therefore not univoqual. Data were provided for information only.

Description | This secondary outcome measure is an electrophysiological testing endpoint. Absolute change from baseline at week 48. After a nerve fiber is depolarized, a sequence of excitability changes, called the 'recovery cycle', occurs before the membrane potential returns to its resting stage. This cycle includes phases in which the nerve excitability is decreased ('refractory period' or increased ('supernormal period'). Refractoriness depends on many factors and its interpretation is therefore not univoqual. Data were provided for information only. |
