Anifrolumab[1] is a monoclonal antibody designed for the treatment of systemic lupus erythematosus.[2]

This drug was developed by MedImmune, which chose to move anifrolumab instead of sifalimumab into Phase III trials for lupus in 2015.[3][4][5]

Adverse effects[edit]

The most common adverse effect in the study was shingles, which occurred in 5% of patients in the low-dose group, to 10% in the high-dose group, and to 2% in the placebo group. Overall adverse effect rates were comparable in all groups.[6]
