Clinical Implementation of a Non-Invasive, Multi-Analyte ddPCR Test to Screen for Androgen Receptor Alterations

Recent studies have shown that alterations of the androgen receptor (AR) are associated with resistance to AR-directed therapy in prostate cancer. Thus, it is crucial to develop robust detection methods for AR alterations as predictive biomarkers to enable applicability in clinical practice. We designed and validated five multiplex droplet digital PCR (ddPCR) assays for reliable detection of 12 AR targets including AR amplification, AR-V7 and 10 AR hotspot mutations as well as AR and KLK3 gene expression from plasma derived cell-free (cf)DNA and cfRNA.
