ReviewDimethyl fumarate (BG-12) for the treatment of multiple sclerosis.
Treatments for multiple sclerosis (MS) are only partially effective and most require a parenteral route of administration and/or may have severe side effects. Dimethyl fumarate is the active compound of BG-12 recently licensed for the treatment of relapsing-remitting MS. The pivotal Phase III trials have demonstrated an approximately 50% reduction of relapse rates compared with placebo paralleled by a reduction in new lesion formation on MRI. ⋯ Severe side effects were not more common than in the placebo group for a treatment period of 2 years. The mode of action is not exactly clear and both immunomodulatory effects and an activation of the transcription factor Nrf2 are suggested. This new oral drug will be a welcome addition to existing MS treatments.
