According to Straits Research the global protein therapeutics market size was valued at $399.76 billion in 2025 and is projected to grow from $427.98 billion in 2026 to $736.06 billion by 2034, registering a CAGR of 7.06% during the forecast period (2026–2034).
The market growth is primarily attributed to the expansion of monoclonal antibody and recombinant protein applications, and increased investment in biopharmaceutical R&D. In addition, the increasing prevalence of chronic diseases, such as cancer worldwide, is driving the demand for innovative protein-based therapies, including monoclonal antibodies and targeted treatments. For example, in February 2024, as per the WHO, global cancer cases are projected to exceed 35 million annually by 2050, emphasizing the urgent need for effective therapies. This rising incidence of cancer fuels the demand for protein therapeutics, supporting the growth of the global protein therapeutics market. Moreover, technological advancements in protein therapeutics present significant opportunities for developing targeted and effective treatments for various cancers and chronic diseases. For example, in April 2025, Amgen’s UPLIZNA (inebilizumab-cdon) received FDA approval for Immunoglobulin G4-related disease (IgG4-RD), expanding its therapeutic applications beyond NMOSD and demonstrating the potential of next-generation antibody therapies. These advancements offer companies the opportunity to innovate and expand their protein therapeutics portfolio, addressing unmet medical needs and capturing new market segments.
North America remains the largest regional market due to its advanced healthcare infrastructure, strong presence of leading pharmaceutical companies, and high adoption of biologic therapies. Asia-Pacific is expected to witness the fastest growth during the forecast period, supported by increasing healthcare spending, expanding biotechnology research, and improving access to advanced treatments. Ongoing investments in product innovation, strategic collaborations, and emerging markets are expected to strengthen global market growth.
