Goal: To develop new therapies for triple negative breast cancer (TNBC), an aggressive form of the disease.
Impact: Dr. Wang is testing a new class of drugs he designed that may be highly effective in treating TNBC. His work could lead to new therapies for this subtype of breast cancer, which currently lacks FDA-approved targeted treatments.
What’s next: He and his team aim to begin clinical development of these drugs.
TNBC is a subtype of breast cancer with a high recurrence rate and a poor prognosis. While chemotherapy is an effective option for patients with TNBC, there is an urgent need to develop targeted treatments for this aggressive disease. Dr. Wang is working on a new class of drugs for TNBC that target a protein on the cell that allows tumors to grow and spread.
Full Research Summary
Research area: Identifying biomarkers for treatment response in breast cancer and developing effective targeted therapies for patients with breast cancer
Impact: Breast cancer has several different subtypes with ER+ being the most prevalent disease, while triple negative being the most aggressive disease. The treatment options are very different. For ER+ patients, even though the hormonal therapies are very effective, there are still 20% patients develop resistance and this trend does not change regardless how many years being on treatment. Therefore, it is critical to develop biomarkers that can help better individualize the therapy and select more rational combination therapies to overcome resistance.
Current investigation: Dr. Wang is using multiple omics data together with clinical phenotypes and in vitro cell and animal models to identify biomarker and study the underlying mechanisms of how these biomarkers might influence drug response and mechanisms of drug actions.
What she’s learned so far: Dr. Wang and her team has identified a series of biomarkers (SNPs/genes) that associated with hormonal treatment in breast cancer and through better mechanistic understanding, they are able to design better combination therapies based on these markers and also better understand mechanistically how these hormonal therapies might work and what are the differences among individual drug. All of these studies would help future personalized therapy of breast cancer, particular ER+ breast cancer.
What’s next: She and her colleagues aim to build more mechanistic studies to understand which subgroups of patients might benefit from these hormonal therapies and to develop new therapies in the treatment of ER+ breast cancer.
Dr. Liewei Wang received her medical degree from FuDan University Medical School, Shanghai, followed by a PhD degree in Pharmacology from the Mayo Clinic. She trained in a leading national center for pharmacogenomics (PGx) research. Currently Dr. Wang is Professor of Pharmacology at Mayo where she has developed a research program focused on the use of genomic technology joined with a cell-based model system and clinical samples to study mechanisms of cancer biology and drug response. As Co-PI of the Mayo-NIH Pharmacogenomics Research Network (PGRN) grant for the past decade she has led PGx functional genomic studies of breast cancer designed to identify and understand biomarkers for response to endocrine and chemotherapy of breast cancer. Among those studies are the BCRF funded project in collaboration with Dr. James Ingle, in which her group has discovered a series biomarkers for endocrine response in breast cancer and they are studying the basic mechanisms associated with these biomarkers to help design better individualized endocrine therapy. She also leads a Mayo program developing new experimental models for breast and prostate cancer. Dr. Wang has published extensively in high impact journals and has received the Astellas Award from Astellas Foundation and the 2016 Leon Goldberg Early Investigator Award from the American Society for Clinical Pharmacology and Therapeutics. Dr. Wang is a member of the Mayo-NCI Comprehensive Cancer Center and Associate Director of the Pharmacogenomics Program of the Mayo Center for Individualized Medicine.
