Giant Cell Arteritis | Treatment Algorithms: Claims Data Analysis | US | 2021


Giant cell arteritis (GCA) is an autoimmune disease marked by inflammation of blood vessels in the head and neck, leading to persistent headaches, flu-like symptoms, and risk of blindness. The most common treatment for GCA is high doses of corticosteroids, typically started immediately after diagnosis to reduce the risk of blindness and tapered over the next 12-24 months. In 2017, the first targeted treatment for GCA, Roche’s Actemra, was approved. Other key autoimmune drugs, including Bristol Myers Squibb’s Orencia, AbbVie’s Rinvoq, and Sobi’s Kineret, are in late-phase trials for GCA, suggesting increasing interest in this potentially lucrative and untapped market.
