On December 4, 2015, Amgen Inc. (Amgen) announced the filing of a Marketing Authorization Application (MAA) with the European Medicines Agency (EMA) for ABP 501, a biosimilar version of AbbVie Inc.’s (AbbVie) Humira® (adalimumab). According to Amgen, its MAA submission included analytical, clinical and pharmacokinetic data. Amgen conducted Phase 3 comparative efficacy and safety studies in both moderate-to-severe plaque psoriasis and moderate-to-severe rheumatoid arthritis patients.
