European Experience with Biosimilars

While there are numerous concerns regarding the use of biosimilar products, the preliminary experience with biosimilar infliximab has been favorable.

Key points:

  • Biosimilars are leading to cost reductions of 30-40%.  In addition, to lowering the cost of infliximab, this is leading to reductions in costs for adalimumab and vedolizumab which are competing as 1st line therapies.
  • In the authors study of the first 210 patients, they did not find any difference in terms of immunogenicity or side effects.  In addition, efficacy was comparable to the ‘originator’ drug.

My take: Infliximab and adalimumab have been blockbuster medications for pharmaceutical companies, in part because they provide a great clinical benefit.  However, if biosimilars are truly biosimilar, the cost reductions will result in their widespread adoption.

  1. Jay,

    Your earlier position statement reflects my thoughts as well. Safety and lack of immunogenicity needs to be fully understood in children with IBD since their long term drug burden is potentially higher and longer. The efficacy and cost savings in Adult RA is of note but less important data set since there are other biologics which do not translate their effects meaningfully from RA to IBD.
