Comparator / control treatment
This is an uncontrolled study. This is a pre-post study design where post-intervention is compared to pre-intervention i.e. secondary outcomes will be measured for 3 months pre-intervention during a 'run-in' phase.
Control group
Active

Outcomes
Primary outcome [1] 308177 0
An excess of serious adverse events such as abscess, osteomyelitis or disseminated BCGosis. Participants will be provided with an information sheet of potential serious adverse events. Participants are encouraged to contact a researcher (via 24/7 contact details) if a potential serious adverse event occurs and clinical review organised if appropriate. Participants will also be questioned about adverse events at 3 monthly clinical reviews. The safety committee will review all potential adverse events during 3 monthly safety committee meetings.

Statistical methods / analysis
A sample size of 20 was chosen as this is a phase 1 pilot study and considered feasible based on specialist experience and estimate of prevalence and incidence of patients with MMN or MADSAM treated in Australian neurology clinics.

Primary outcomes will be presented descriptively. For secondary outcomes paired t-test or non-parametric paired rank test after review of data for parametric consistency, for individual comparisons of paired time points. Paired regression analysis with robust estimator of standard error for series analysis of time points. As the study is exploratory determination of analytical methods may be modified post-hoc.

Summary
Brief summary
The only treatment (intravenous immunoglobulin) shown to be effective in MMN and some patients with MADSAM is expensive and may not slow the long-term decline in physical ability (function). Bacille Calmette Guerin (BCG) vaccine is an intradermal (injected just beneath the skin) vaccine used to prevent tuberculosis; BCG has many effects on the immune system and may have a beneficial effect on the underlying mechanisms of MMN and MADSAM. The purpose of this trial is to study the safety and potential effectiveness of BCG in MMN and MADSAM. We hypothesise that BCG will be a therapeutic option that is safe and will improve outcomes (symptoms and physical ability) in MMN and MADSAM.
