AI-Powered Platform Develops Precision Molecular Treatments for Cancer

In a significant advancement in cancer treatment, a collaborative team from the Technical University of Denmark (DTU) and the Scripps Research Institute has developed an innovative artificial intelligence (AI) platform capable of designing custom molecular treatments, significantly enhancing the precision and speed of cancer immunotherapy. This groundbreaking methodology was detailed in a study published in the prestigious journal Science on July 24, 2025.

The AI platform demonstrates an ability to create unique protein minibinders that arm T cells in the immune system to specifically target and eliminate cancer cells. Timothy P. Jenkins, an Associate Professor at DTU and the study's lead author, emphasized the transformative potential of this technology, stating, “We are essentially creating a new set of eyes for the immune system.” Traditional methods for developing tailored cancer treatments can take years, but with the AI platform, this process can be reduced to a matter of weeks, with lead molecules ready for testing in as little as 4 to 6 weeks.

The AI system functions by designing molecular keys that target cancer cells through peptide-major histocompatibility complex (pMHC) molecules. This innovative approach addresses a significant challenge in the field of cancer immunotherapy—ensuring that treatments can target tumor cells while sparing healthy tissue. According to Kristoffer Haurum Johansen, a postdoctoral researcher at DTU and co-author of the study, the results of initial laboratory tests were promising, stating, “It was incredibly exciting to take these minibinders, which were created entirely on a computer, and see them work so effectively in the laboratory.”

The researchers applied their AI platform to create minibinders against a well-established cancer target, NY-ESO-1, which is prevalent in various cancer types. Additionally, they successfully generated binders for a target identified in a metastatic melanoma patient, further demonstrating the platform’s versatility in personalized immunotherapy applications.

A critical innovation within this research was the implementation of a virtual safety check, allowing the team to screen designed minibinders against pMHC molecules present on healthy cells. This filtering process helps identify potentially harmful side effects before clinical experiments commence, enhancing the safety profile of developed therapies. Sine Reker Hadrup, a professor at DTU and co-author of the study, noted, “Precision in cancer treatment is crucial. By predicting and ruling out cross-reactions already in the design phase, we were able to reduce the risk associated with the designed proteins and increase the likelihood of designing a safe and effective therapy.”

Looking ahead, Jenkins anticipates that the AI-driven method could be ready for initial clinical trials within five years. This treatment will closely resemble current therapies utilizing genetically modified T cells, such as CAR-T cell therapy, which is already in use for some forms of lymphoma and leukemia. The proposed process involves extracting a patient’s immune cells, modifying them with the AI-designed minibinders in a laboratory setting, and subsequently reinfusing them into the patient to act as targeted agents against cancer cells.

This innovative approach presents a promising future for the field of oncology, potentially revolutionizing how personalized medicine is applied in cancer treatment. As researchers continue to refine this technology, the implications for patient outcomes and the broader landscape of cancer care remain significant. The possibility of rapid, precise, and personalized treatments could lead to improved survival rates and better quality of life for patients battling cancer.
