According to a new series of reports on the U.S. market for immunology drugs by iData Research (www.idataresearch.com), projections show a gradual fall in HUMIRA® market share after 2020 due to the entry of infliximab and etanercept biosimilars, as well as other new drugs. The revenues from HUMIRA® currently account for an estimated 34% of the total U.S. immunology drug market. However, since the patent expiry for HUMIRA® in 2016, there are currently two HUMIRA® biosimilars, namely Amjevita™ and Cyltezo™. However, these drugs are not able to launch due to Humira's strong ancillary patents which will protect them from losing their exclusivity until 2023. These products will cause the average selling price (ASP) of HUMIRA® to decline over the next several years, further deepening the market share erosion caused by biosimilars after 2023.
