The purpose of this study is to give an overview of the new treatments approved by the U.S. Food and Drug Administration (FDA) for use in psoriatic arthritis (PsA).
FDA has approved three new drugs for PsA: Certolizumab-pegol: a PEGylated Fc-free tumour necrosis factor inhibitor (TNFi); ustekinumab: an anti interleukin (IL)-12 and IL-23 mAb; and apremilast and oral phosphodiesterase 4 inhibitor. On well designed and extensive developing programmes, all three drugs proved to be effective for the treatment of most PsA manifestations, including peripheral arthritis, skin involvement, enthesitis, dactylitis, quality of life and radiographic progression in patients failing traditional disease modifying drugs (DMARDs) and TNFi. Safety profile of all three drugs seems to be reassuring until now, although long-term data are still not available. Although Certolizumab-pegol is likely to be placed among the other TNFi, ustekinumab and apremilast, due to lower efficacy on arthritis, are being more frequently used as second-line therapy after TNFi failure, especially among rheumatologists.
There are new therapeutic options approved for the treatment of PsA. For the first time, well proved effective therapies with a different mechanism of action than the inhibition of TNF alpha are available for the treatment of this progressive disease.
