%X <B>BACKGROUND: </B>The objective of this systematic review was to provide an overview of current developments and potentially available therapeutic options for polymyalgia rheumatic (PMR) and giant cell arteritis (GCA), in the coming years.<BR><B>METHODS: </B>We conducted a systematic review of 17 national and international clinical trial databases for all disease-modifying anti-rheumatic drugs (DMARDs) for PMR and GCA that are already marketed, in clinical development or withdrawn. The search was performed on January 2024, with the keywords "polymyalgia rheumatica" and "giant cell arteritis". For each molecule, we only considered the study at the most advanced stage of clinical development.<BR><B>RESULTS: </B>For PMR, a total of 15 DMARDs were identified: 2 conventional synthetic DMARDs (csDMARDs), 11 biologic DMARDs (bDMARDs) and 2 targeted synthetic DMARDs (tsDMARDs). For GCA, 18 DMARDs were identified: 2 csDMARDs, 14 bDMARDs and 2 tsDMARDs. Currently, there are only 2 approved corticosteroid-sparing therapies in these diseases, which both target the IL-6 signaling pathway, namely tocilizumab in GCA and sarilumab in PMR. Most of the molecules in current development are repurposed from from other conditions and clinical research in PMR/GCA seems to be mostly driven by the potential to repurpose existing treatments rather than by translational research.<BR><B>CONCLUSIONS: </B>This systematic review identified 23 DMARDs evaluated for PMR and GCA: 3 csDMARDs, 17 bDMARDs and 3 tsDMARDs. Several promising treatments are likely to be marketed in the coming years.
