Biosimilar Market: Transforming Affordable Biologics and Expanding Global Healthcare Access

Biosimilars are biologic medical products that are highly similar to already approved reference biologics, with no clinically meaningful differences in safety, purity, or effectiveness. Unlike generic drugs, biosimilars are derived from living organisms, making their development more complex and highly regulated.

The biosimilar market plays a crucial role in improving patient access to advanced therapies, particularly in areas such as oncology, autoimmune diseases, diabetes, and endocrinology. As biologics account for a significant portion of global pharmaceutical spending, biosimilars offer a sustainable solution by reducing treatment costs without compromising outcomes.

With increasing acceptance among physicians and patients, biosimilars are gradually reshaping treatment protocols and expanding healthcare accessibility across both developed and emerging markets.

The global biosimilar market size was valued at USD 32.9 Billion in 2025. Looking forward, IMARC Group estimates the market to reach USD 210.4 Billion by 2034, exhibiting a CAGR of 22.90% from 2026-2034. Europe currently dominates the market. The expiration of patents for major biological drugs, growing awareness about the efficacy and cost-effectiveness of biosimilars, the rising prevalence of chronic diseases worldwide, and continual advancements in biopharmaceutical manufacturing technologies are some of the major factors boosting the biosimilar market share.

Latest News and Developments:

December 2024: Intas Pharmaceuticals, through its U.S. division Accord BioPharma, expanded its cancer therapy biosimilar portfolio by acquiring Coherus BioSciences' UDENYCA® business. UDENYCA® is the only biosimilar to Amgen’s NEULASTA® in the U.S., used to reduce infection risk after chemotherapy. This acquisition positions Accord for growth in the biosimilar sector. Additionally, Intas entered a global licensing agreement with Xbrane Biopharma to co-develop Xbrane's nivolumab biosimilar, aiming for a 2028 U.S. launch, enhancing access to cancer treatments and improving healthcare system efficiency.

December 2024: Biocon Biologics received USFDA approval to launch its Stelara biosimilar by February 2025, targeting autoimmune conditions such as Crohn's disease and plaque psoriasis. Despite facing competition from five other biosimilars, the launch is expected to significantly enhance Biocon's revenue and profitability. The move positions Biocon to capture a larger share of the growing biosimilars market, particularly in autoimmune treatments.
