Psoriatic Arthritis | Current Treatment | EU5 | 2017

Following the European Medicines Agency’s approvals of the PDE-4 inhibitor Otezla and the IL-17 inhibitor Cosentyx for psoriatic arthritis (PsA), treatment of this disease in the EU5 has begun to move away from its heavy reliance on TNF inhibitors. Both IL-17 inhibition and PDE-4 antagonism are new mechanisms of action for rheumatologists. Their early perceptions of these two agents can shed light on the long-term commercial prospects for the two drug classes. Also affecting the PsA therapy market in the EU5 are the launches of biosimilar etanercept and biosimilar infliximab, both of which will further reduce the uptake of the brand TNF inhibitors and may affect use of later-line therapies. These two dynamic forces are poised to reshape the treatment algorithm for PsA.
