Comprehensive Review Exploring Novel Treatments for Psoriatic Arthritis and Axial Spondyloarthritis from 2016 to 2021

Over the past decade, numerous novel therapies have been approved for use in the seronegative spondyloarthritides, including psoriatic arthritis and axial spondyloarthritis. With large variability seen in the spondyloarthritides with respect to presentation and perhaps pathogenesis, potential therapies continue to be discovered and trialled in the hope of better controlling disease activity. This review details therapies that have emerged for the treatment of psoriatic arthritis and axial spondyloarthritis from 2016 to 2021. We discuss those that have been approved for use in the USA and those that remain under investigation.
