DUBLIN--(BUSINESS WIRE)--The "Bispecific Antibody & Cancer Patent Landscape Analysis" report has been added to ResearchAndMarkets.com's offering.
The development of bispecific antibodies (bsAbs) in oncology is experiencing rapid growth, accompanied by significant clinical advancements. According to recent data, more than 85% of bsAbs in clinical trials are cancer treatments, with approximately 600 bsAbs currently in clinical trials. To date, 11 bsAbs have received regulatory approval for use in cancer, ten of them by the US FDA. This expansion reflects the growing interest in these innovative therapeutic agents. Bispecific antibodies are engineered proteins designed to bind simultaneously to two distinct antigens. They can bridge two cell types (in-trans binding) or engage two molecules on the membrane of one cell (in-cis binding).
BsAbs that bridge cells represent the largest group, with T-cell redirection as the most common denominator. T-cell engagers bind both cytotoxic T cells and tumor cells, promoting a direct immune response against the tumor. Several bsAbs have recently received regulatory approvals. In December 2024, the U.S. FDA granted accelerated approval of a HER2 HER3 bsAb for adults with advanced, unresectable, or metastatic non-small cell lung cancer (NSCLC) harboring a neuregulin 1 (NRG1) gene fusion with disease progression on or after prior systemic therapy, or advanced, unresectable, or metastatic pancreatic adenocarcinoma harboring an NRG1 gene fusion with disease progression on or after prior systemic therapy.
However, challenges remain, such as the complexity of production, toxicities (cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome, infusion-related reactions), and the need to optimize the stability and half-life of the molecules. Innovative approaches, such as advanced antibody engineering technologies and the development of new molecular formats, are being explored to overcome these obstacles. Understanding the intellectual property position and strategy of these various players is crucial in this evolving context. Detecting business risks and opportunities, anticipating emerging technologies, and enabling strategic decisions to strengthen market position can be achieved through this knowledge.
Between 1986 and the early 2000s, the number of patent publications is low but increasing. From 2010, the field is experiencing a significant acceleration, culminating in 2023 with more than 400 patent families. In the 1980s and 1990s and early 2000s, many advances were made in academic research such as the generation of the 1st asymmetric format, the 1st demonstration of T cell redirection, the 1st recombinant fragment-based formats, the 1st solution to light chain (LC) association issue through species-restricted LC pairing, the 1st solution to chain-association issue through use of complementary heavy chain (HC) (knobs into holes) and common LC, the 1st symmetric format, the discovery that natural human IgG4 is bispecific, the dual variable domain-Ig symmetric format pioneered, etc. All these innovations have contributed to the establishment of bsAbs. Then, in 2009, the bsAb catumaxomab (a T lymphocyte antigen CD3 epithelial cell adhesion molecule (EpCAM)) received the European Union approval for the treatment of malignant ascites. Five years later, the blinatumomab (CD3B lymphocyte antigen CD19) was FDA approved. It has been approved in the EU in 2015.
