Researchers from Uppsala University and KTH Royal Institute of Technology have developed a groundbreaking antibody with the potential to revolutionize cancer treatment. This novel antibody combines three distinct functions, making it a powerful tool for personalized immunotherapy.

The antibody works by:
● Targeting cancer cells: The antibody is designed to identify and bind to specific mutations and gene changes, known as neoantigens, that are unique to cancer cells.
● Delivering a drug package: The antibody itself acts as a delivery system, carrying a payload of anti-cancer agents directly to the tumor site.
● Activating the immune system: The antibody simultaneously stimulates the immune system, specifically a type of immune cell called T cells, to attack the cancer cells.
This “3-in-1 design” results in a significantly enhanced T-cell response against the tumor, leading to more effective cancer treatment.

Advantages of the New Antibody

The development of this antibody presents several key advantages:
● Personalized Treatment: The antibody can be tailored to each patient’s specific cancer type and tumor characteristics by modifying the peptide part of the drug, allowing for truly personalized treatment.
● Scalability and Cost-Effectiveness: While customized precision medicines are often expensive and time-consuming to produce, this antibody is designed for large-scale production. The targeting antibody can be produced in bulk, while the peptide part can be quickly and affordably synthesized on a smaller scale as needed.
● Improved Safety: In animal studies, the new antibody demonstrated improved safety compared to previous cancer treatments.
● Faster Treatment Initiation: The ability to rapidly tailor the peptide component to a specific tumor could significantly reduce the time between diagnosis and treatment, potentially improving patient outcomes.

The researchers are optimistic about the potential of this new antibody and are working towards clinical trials in humans. The study has been published in Nature Communications.
