We identify personalised cancer treatments for patients based on their tumour genetics. For each patient, we build a genetically matched fruit fly model of the tumour, which is used for large-scale drug screening to find novel and effective drug combinations. This platform can treat even difficult cancers with combinations of approved drugs. Nearly all combinations incorporate non-cancer drugs, making them less toxic and more affordable. Using our proprietary screening data, we are building a powerful AI-driven digital health tool, which can predict effective treatment options rapidly. Our in vivo, high throughput drug screening platform is also used to power biopharma discovery and development.
