Speaking on the pharmacogenomics of anticancer agents, predictive biomarkers, and developmental therapeutics in breast cancer

Prof. Ma’s research is focussed on pre-clinical and early phase clinical investigations in developing molecular therapeutics for breast cancer. She has designed and conducted several trials in genomic biomarker focused breast cancer populations. Prof. Ma led the Phase III Alliance trials, which aimed to validate neoadjuvant biomarkers predictive of long-term outcomes and to evaluate neoadjuvant therapy in estrogen receptor-positive (ER+) and HER2 negative (HER2-) breast cancer patients resistant to endocrine therapy (ET). Aside from clinical trial development, Prof. Ma’s laboratory studies clinical specimens and patient-derived xenograft models to investigate biomarkers of responsiveness for targeted agents.
