Rheumatoid Arthritis | Treatment Algorithms | Claims Data Analysis | US | 2018

MARKET OUTLOOK

Treatment of rheumatoid arthritis (RA) is typically initiated with cost-effective conventional DMARDs, such as methotrexate. For  RA patients who are refractory to conventional DMARDs, the U.S. market is crowded with efficacious biologics, including the blockbuster tumor necrosis factor alpha (TNF-alpha) inhibitors Amgen’s Enbrel, AbbVie’s Humira, and Janssen’s Remicade, as well as non-TNF-alpha inhibitors such as Bristol-Myers Squibb’s Orencia and Roche/Genentech’s Rituxan and Actemra. In addition, Pfizer’s JAK inhibitor Xeljanz, the first targeted oral treatment for RA, has been approved for almost six years in the United States and is gaining steady uptake in early lines of therapy. The FDA’s approval of Regeneron/Sanofi’s Kevzara in 2017 added a second IL-6 inhibitor to the armamentarium for RA.
