Although financial incentives introduced by Japan's 2022 health policy did not result in a reduction in overall drug costs, biosimilar use in oncology significantly increased.
Henlius and Organon’s pertuzumab biosimilar met phase 3 goals; Meitheal expanded its US biosimilars; Celltrion’s subcutaneous infliximab (Zymfentra) showed monotherapy could be as effective as combination therapy for inflammatory bowel disease.
Adalimumab biosimilars have seen a significant increase in market share, from 2% in early 2024 to 22%, as payers and pharmacy benefit managers begin to prioritize these biosimilars over the reference product, Humira.
Transformative cell and gene therapies (CGT) offer promising treatments for serious conditions, but high costs and complex biologics limit competition, requiring policies that support the development of biosimilars to enhance affordability and patient access.
The Inflation Reduction Act (IRA) has modestly boosted oncology biosimilar uptake through Medicare reimbursement, but its impact has been limited due to preexisting competitive market conditions.
