Investigators
Eligibility Criteria
Inclusion Criteria
- •Patients with documented clinical diagnosis and electrophysiological evidence of MMN
- •Patients who have previously responded to intravenous immunoglobulin (IVIG) and have been on stable treatment with IVIG for at least 12 weeks prior to screening
- •Patients treated with the equivalent of ≥0.4g/kg body weight (bw) IVIG per month
- •Provision of informed consent by patient
Exclusion Criteria
- •Aspartate aminotransferase (ASAT) or alanine aminotransferase (ALAT) concentration \>2.5 times the upper normal limit (UNL)
- •Creatinine concentration \>1.5 times the UNL
- •Known allergic reactions to blood products
- •Any skin disease interfering with the assessment of injection site reactions
- •Any other medical condition, which in the opinion of the investigator, might interfere with successful completion of the protocol
- •Any condition likely to interfere with the evaluation of the study drug or satisfactory conduct of the trial
- •Participation in a study with an investigational drug within three months prior to enrolment
- •Patients treated with the equivalent of \>2.0g/kg bw IVIG per month
Outcomes
Primary Outcomes
Mean Overall MRC Score at Baseline and Week 24
Time Frame: Baseline and week 24
The 200-point MRC sum score is the sum of scores for 20 bilateral (left and right side) muscle groups, each rated between 0 (no movement) to 5 (normal movement/power). A higher MRC sum score indicates greater muscle contraction/limb movement.
Change From Baseline to Week 24 in Muscle Strength
Time Frame: Baseline to week 24
The change in Medical Research Council (MRC) score was determined at week 24 compared to baseline using descriptive statistics and nonparametric, two-sided 95% confidence intervals based on the Hodges-Lehmann method. Data for one of the eight subjects was from week 13 as week 24 data were not available. The 200-point MRC sum score is the sum of scores for 20 bilateral (left and right side) muscle groups, each rated between 0 (no movement) to 5 (normal movement/power). A higher MRC sum score indicates greater muscle contraction/limb movement. Positive values for change in MRC sum score indicate improvement, with a more positive value indicating greater muscle contraction/ limb movement compared with the value at baseline.
Secondary Outcomes
- Treatment Satisfaction at Baseline and Week 25(At baseline and week 25)
- Change From Baseline to the Completion Visit in Motor Function(Baseline to the completion visit (up to week 25))
- Change From Baseline to Week 24 in Disability(Baseline to week 24)
- Mean Disability Score at Baseline and Week 24(Baseline and Week 24)
- Health-Related Quality of Life at Baseline and Week 25(At baseline and week 25)
- Mean Motor Function Score at Screening and Week 25(Screening and week 25)
- Overall Health Status at Baseline and Week 25(Baseline and week 25)
- Number of Patients With Adverse Events (AEs) by Severity and Relatedness(For the duration of the study, up to Week 25)
- Rate of AEs by Severity and Relatedness(For the duration of the study, up to Week 25)
- Number of Patients With Local/Injection Site Reactions(For the duration of the study, up to Week 25)
- Number of Patients With Clinically Relevant Changes in Vital Signs(Baseline to Week 25)
- Number of Patients With Clinically Relevant Changes in Laboratory Parameters(Baseline to Week 25)
