Biosimilar drugs: In 2016 biosimilar agent CT-P13 (developed by Celltrion, also known as infliximab-dyyb; Remsima®, Inflectra®) was approved in several countries for use in all indications for which reference infliximab is approved [1-2,7]. Although the approval covers the same indicated conditions as the reference drug, it should be noted that CT-P13 is approved as a biosimilar and not as an interchangeable product. Flixabi® (a.k.a. Renflexis®, SB2), another infliximab biosimilar (manufactured and commercialized by Biogen in the EU) received EMA marketing authorisation in 2016. PF-06438179 is another potential biosimilar to infliximab being developed by Pfizer Inc. .
