Clinical Trials

Reducing the frequency of Autoimmune adverse events in the treatment of Multiple sclerosis with alemtuzumab using B-celL dEpletion (RAMBLE): a phase II, randomised, placebo-controlled clinical trial

Type of Study/Intervention


Recruitment Status


Form of MS

Relapsing Remitting MS

Brief summary

To reduce the occurrence of autoimmune adverse events from the treatment of multiple sclerosis (MS) with alemtuzumab through the subsequent targeted use of rituximab. The hypothesis to be tested is that rituximab therapy following alemtuzumab treatment for MS will reduce the frequency of autoimmune adverse events.

If this strategy proves to be safe and is effective in preventing or significantly reducing the frequency of autoimmune adverse events in the treatment of MS with alemtuzumab, then this approach could be adopted immediately in a large number of pwMS with an immediate reduction in co-morbidity.
