PreludeDx is a breast cancer-focused genetic testing startup that developed a proprietary risk assessment test, DCISionRT, for patients with ductal carcinoma in situ (DCIS). Patients with DCIS have abnormal cells inside milk ducts in the breast, which is considered the earliest form of breast cancer. DCISionRT provides a recurrence risk score after breast-conserving surgery and predicts whether patients would benefit from radiation therapy. The risk score is based on an individual’s tumor biology, protein expression from seven biomarkers, and other pathologic risk factors.
Key customers and partnerships
The technology was licensed from the University of California, San Francisco, and built on research from the National Cancer Institute. PreludeDx is focused on developing breast cancer diagnostic tools that can help improve treatment decisions.
Funding and Financials
In March 2022, the firm raised USD 20 million in a funding round led by Evidity Health Capital, which was allocated for the market expansion of its DCISionRT test and to develop its precision radiogenomics platform for diagnosing other cancers.
