Tempus Announces Novel Pan-Cancer HRD-RNA Algorithm
Tempus AI, Inc. (NASDAQ:TEM), a technology company leading the adoption of AI to advance precision medicine, today announced the launch of its new HRD-RNA algorithm. This next-generation model represents a significant improvement in identifying Homologous Recombination Deficiency (HRD), providing a more robust, functional assessment of tumor biology compared to traditional static DNA-based assays.
Tempus HRD-RNA is an AI-driven, 1,660-gene logistic regression model designed to identify patients likely to respond to platinum-based chemotherapy or PARP inhibitors. Unlike traditional DNA tests that analyze static "genomic scars"—which may persist even after a patient develops drug resistance—this RNA-based approach provides a dynamic, real-time assessment of a tumor's functional status.
By analyzing gene expression rather than structural DNA damage, the algorithm can detect HRD in patients and cancer types where genomic scarring is rare or difficult to identify. This advanced methodology allows the model to capture HRD status in patients who might be missed by DNA-based assays, significantly expanding the population that can be identified for potentially life-saving therapies.
A real-world validation study demonstrates that HRD-RNA positive metastatic pancreatic patients treated with first line platinum-based regimens showed a significant reduction in mortality risk compared to those receiving non-platinum first line therapies. These findings, including the complete supporting data, will be published later this year.
"Our HRD-RNA algorithm gives physicians a critical tool to better inform treatment decisions," said Halla Nimeiri, MD, Chief Development Officer at Tempus. "By looking at the transcriptome, we can identify a functional HRD status that is more dynamic than what can be seen in the genome alone. This work exemplifies how Tempus is leveraging its AI platform and vast repository of data to create clinical solutions with real-world impact."
HRD-RNA is currently available for research use only in the detection of HRD status within solid tumor patient populations and for the identification of patients likely to respond to platinum regimens or PARP inhibitor therapy. Clinical availability is expected later this year.
