While 118 biologics are expected to lose patent protection in the US over the next decade, that $234 billion opportunity for biosimilar developers may not materialize because of several challenges, according to a new report from research company IQVIA. Only 10% of those 118 biologics have a biosimilar in the pipeline
and currently, only 14 out of 62 biologics that will lose patent protection at the end of 2024 have biosimilars, the report says. An additional 19 biologics have biosimilars in clinical development, with five biosimilars already winning FDA approval and expecting to launch this year, including biosimilars for AstraZeneca's Soliris, Biogen's Tysabri, Amgen's Prolia/Xgeva, and J&J's Stelara. So why such a gap in biosimilar development considering how many biologics are coming off-patent? The IQVIA report, entitled "Assessing the Biosimilar Void in the U.S.," points to challenges in "regulatory requirements, market acceptance, high investment costs, obscurity around interchangeability, and reimbursement." |
