With the biggest biosimilar launch in the U.S. just days away, Humira’s (adalimumab) record-breaking ride is quickly slowing down, but the Abbvie Inc. mega-blockbuster immunology drug is nowhere near the end of its road.

Besides revving their engines against Humira, the new launches will be looking to overtake Amgen Inc.’s biosimilar, Amjevita, which got a five-month headstart in the U.S., thanks to the first-mover status Amgen earned for being the first to sign a licensing agreement with Abbvie.

Watchers of the Bruton’s kinase (BTK) inhibitor space may be casting renewed skepticism in that direction after Merck KGaA disclosed April 12 that the U.S. FDA placed a partial clinical hold on the sign-up of more patients in work testing evobrutinib in relapsing multiple sclerosis (MS) – but BTK efforts in MS continue in various quarters.
