The research presented in this report is meant only to help participating organizations make topic selection decisions. Comprehensive review, quality assessment, and synthesis of evidence from the studies presented here will follow only if the participating organizations select this topic. Previous Report Kahwati L, Giger K, Ali R, Gartlehner G. Targeted immune modulators: plaque psoriasis and psoriatic arthritis. Portland, OR: Center for Evidence-based Policy, Oregon Health & Science University; 2020.1 Background and Context Plaque psoriasis is a chronic inflammatory disease characterized by scaling lesions that affect the skin, scalp, and joints.2,3 The severity of plaque psoriasis is usually classified by the percentage of body surface area involved.4,5 Psoriatic arthritis is a chronic inflammatory arthritis that, in most cases, follows the onset of psoriasis; symptoms include pain and stiffness in the affected joints as well as tenderness, swelling, and sometimes loss of range of motion.6 Diagnosis is made on a clinical basis and by ruling out other types of arthritis. The precise etiology of psoriasis and psoriatic arthritis is not completely understood, but likely involves genetic, immunological, and environmental factors.5,7 TIMs are a group of medications used to treat plaque psoriasis and psoriatic arthritis by selectively blocking mechanisms involved in the inflammatory and immune response.6,7 These are often defined by the mode of action and classified into 3 categories—T-cell modulating agents, tumor necrosis factor-alpha (TNF-α) inhibitors, and interleukin (IL)-inhibitors—though other mechanisms now exist.8,9 The US Food and Drug Administration (FDA) approved the first TIM in 1998, and a variety of additional agents, including biosimilars, have since been approved for plaque psoriasis and psoriatic arthritis. At present, some TIMs are approved only for plaque psoriasis or only for psoriatic arthritis, while some are approved for both indications (Table 1).10 State Medicaid program administrators are considering an updated review of the evidence of the effectiveness and harms of TIMs for plaque psoriasis and psoriatic arthritis to aid in managing this class of drugs. The previous review on this topic was completed in March 2020.1 Table 1.
