Abstract

Ravulizumab (ULTOMIRIS^®) is the first long-acting complement C5 inhibitor (administered intravenously every 8 weeks) to be approved in several countries globally, for adults with generalised myasthenia gravis (gMG) who are anti-acetylcholine receptor antibody-positive (AChR Ab+). In the phase III CHAMPION MG trial, intravenous ravulizumab was associated with significant improvements in the MG-Activities of Daily Living scale at week 26 of treatment compared with placebo in adults with AChR Ab+ gMG. Improvements in the Quantitative MG scale total score were also significantly higher in ravulizumab than placebo recipients. These improvements were seen as early as week 1 of treatment initiation and were sustained to week 26. Ravulizumab was generally well tolerated; the most common treatment-emergent adverse events were headache, diarrhoea and nausea. Efficacy and tolerability data for up to 1 year from the ongoing open-label extension phase are consistent with those from the randomized, placebo-controlled phase; further results are awaited with interest. Thus, ravulizumab is an efficacious, generally well tolerated and convenient treatment option in adults with AChR Ab+ gMG, expanding the options available for gMG management.
