Biography

Dr. Topalian received her medical degree from Tufts University School of Medicine in 1979.  She completed her residency in general surgery at the Thomas Jefferson University Hospital in Philadelphia and continued to hold two fellowships: the first in Pediatric Surgery Research at the Children’s Hospital of Philadelphia (1982-1983), and the second in Surgical Oncology at the National Cancer Institute, NIH in Bethesda, Maryland (1985-1989).  After a 21-year tenure in the Surgery Branch of the National Cancer Institute, Dr. Topalian joined the Johns Hopkins faculty in 2006 to lead the Melanoma Program in the Sidney Kimmel Comprehensive Cancer Center.

Dr. Topalian is a physician-scientist whose research interests focus on cancer immunology and immunotherapy.  She has published over 100 original research articles and reviews in this area and is internationally recognized for this work.   Dr. Topalian’s basic studies of human anti-tumor immune responses have provided a foundation for the translational development of immunotherapies for melanoma and other cancers, including cancer vaccines, adoptive T cell transfer, and immune-modulating monoclonal antibodies.  Her early work established that cytolytic “killer” T lymphocytes in melanoma patients could specifically recognize tumor cells from the same patient.  Later studies confirmed the existence of “shared” melanoma antigens (proteins) among tumors from different patients, paving the way for the clinical development of melanoma vaccines.  Her seminal investigations into the role of CD4+ T “helper” cells in human anti-tumor immune responses revealed the existence of tumor-specific CD4+ T cells in patients with melanoma and other cancers, and biochemical and molecular methods were devised for identifying the recognized tumor-associated proteins.  

As the Director of the Melanoma Program, Dr. Topalian’s current research focuses on modulating immune checkpoints such as PD-1 and PD-L1 in cancer therapy, and discovering biomarkers predicting clinical outcomes following treatment. She continues to work on devising optimal melanoma vaccines, based on biochemical and structural analyses, with the goal of exploring combination treatment regimens of vaccines with PD-1 blocking drugs.  These pioneering efforts have opened new avenues of scientific interest and clinical investigation in cancer immunology, and have helped to establish immunotherapy as a treatment modality for cancer.

    Research Summary

    Dr. Topalian's research prior to joining Hopkins revealed the existence of melanoma-associated proteins ("antigens") specifically recognized by human CD8+ killer and CD4+ helper T cells, paving the way for the clinical development of melanoma vaccines. Disappointing results with cancer vaccines in the clinic led to the realization that melanoma and many other human cancers can avoid immune detection and destruction by displaying molecular shields and secreting immune-suppressive factors. Dr. Topalian has led the clinical development of immune-modulating monoclonal antibodies to break through this shield and effectively treat patients with melanoma and other solid tumors.  In collaboration with an interdisciplinary research group at Hopkins, Medarex/Bristol Myers-Squibb, and other medical instituions, it was found that patients with treatment-refractory advanced metastatic cancers could respond to blockade of the immune cell inhibitory receptor programmed death-1 (PD-1) or its partner molecule PD-L1 on tumor cells. Research led by Dr. Topalian has characterized the pharmacodynamics of anti-PD-1 and anti-PD-L1 drugs and has explored tumor molecular markers predictive of clinical response. Since animal models suggest that blockade of PD-1 and PD-L1 synergizes with cancer vaccines, Dr. Topalian has continued to search for optimal tumor target antigens, investigating mutated peptides, phosphorylated peptides, and structural interactions between T cell receptors and these antigens in collaboration with Dr. Roy Mariuzza at the University of Maryland.  Combination treatment regimens of anti-PD-1/PD-L1 with other immune-modulating antibodies, kinase inhibitors, and epipigenetic therapy are under development.
