Rheumatoid Arthritis | Disease Landscape and Forecast | G7 | 2018

The mature rheumatoid arthritis (RA) market boasts ten different biologics representing several distinct drug classes, including blockbuster tumor necrosis factor alpha (TNF-α) inhibitors Enbrel (Amgen), Humira (AbbVie), and Remicade (Janssen); five non-TNF-α biologics, including the recently approved IL-6 inhibitor Kevzara; and oral Jak inhibitors Xeljanz (Pfizer) and recently approved Olumiant (Eli Lilly). The TNF-α inhibitors are the most widely prescribed biologics for RA patients refractory to conventional DMARDs, and the non-TNF-α biologics and Jakinhibitors largely compete for use in TNF-refractory patients. However, the premium-priced branded TNF-α inhibitors face a competitive threat from the launch of biosimilars, including biosimilar infliximab and biosimilar etanercept, which provide cost-effective alternatives. With the impending entry of additional Jak inhibitors (AbbVie’s upadacitinib, Galapagos’s filgotinib) and biosimilars of several other TNF and non-TNF biologics, marketers are faced with fierce competition and increasing challenges to gain market uptake.

Questions answered:

  • What are key opinion leaders’ perceptions of the advantages and disadvantages of these drugs? What factors influence the prescription of one TNF-α inhibitor over another?
  • What are key opinion leaders’ perceptions of the currently marketed non-TNF-α inhibitor biologics and novel oral kinase inhibitors, and where do these agents fit in their current treatment approach? Which emerging agents are likely to be most successful in targeting the TNF-refractory patient segment and gaining uptake in the RA market?
  • What will be the impact of the entry of additional novel oral therapies on the treatment algorithm for RA? In which patient segments and lines of treatment will these oral therapies most likely be used? What is this drug class’s market potential in RA?
  • How will the entry of biosimilars affect the market sales and patient share of currently marketed RA agents and the entry of emerging therapies?
