PALO ALTO/MCLEAN - Guardant Health (NASDAQ:GH), a $9 billion precision oncology company whose stock has surged over 200% in the past year, and Zephyr AI announced a strategic partnership aimed at developing novel cancer biomarkers for drug development and targeted therapy selection.

The collaboration will combine Guardant’s molecular data with Zephyr AI’s analytics platform to identify biomarkers that could potentially improve cancer treatment outcomes, according to a press release statement from the companies.

The partnership will integrate with Guardant’s existing artificial intelligence capabilities, focusing on using multimodal molecular data to generate predictions of targeted cancer therapy responses that can be validated through real-world data.

"By combining our industry-leading molecular data with Zephyr AI’s advanced analytics platform, we’re taking another major step toward realizing the full potential of precision oncology," said Helmy Eltoukhy, chairman and co-CEO of Guardant Health.

Allen Chao, CEO of Zephyr AI, added that the collaboration represents "the convergence of unmatched real-world data, leading-edge diagnostics and cutting-edge machine learning."
