Profile

My research focus is on new therapeutic strategies focusing on the phosphatidylinositol-3 kinase (PI3K)/Akt and correlated pathways in triple-negative, hormone-refractory and HER2-overexpressing refractory breast cancers, using biologically-based targeted agents. I plan to perform molecular analysis of individual breast cancers in an attempt to determine how the biology of the cancer affects the response to the therapeutic agent. It is also my goal to play a key role in elucidating mechanisms of therapy resistance for patients with triple-negative, resistant ER-positive and resistant HER2-positive breast cancers. Ultimately this will result in better and more rational patient/therapy selection.

My role as a clinical investigator are as follows:
1) Develop a Clinical Breast Cancer Research Program with strong links to laboratory efforts throughout the medical center and if necessary, external to the institution. This goal involves collaboration with prestigious investigators within and outside Vanderbilt, and consists of a bidirectional process: observations made in the clinic and correlative studies in tissue samples from clinical trial patients with breast cancer lead basic scientists to investigate new areas of research. Conversely, pre-clinical data focused on relevant signaling pathways in breast cancer are the basis for development and implementation of novel hypothesis-driven clinical trials.
2) Expand preclinical therapeutic testing with tumors freshly obtained from the breast cancer patients in clinical trials. Tissue collection (primary tumor paraffin blocks and/or fresh frozen tissue) in all investigator-initiated breast cancer clinical trials is required for patient enrollment. Thanks to our Multidisciplinary Breast Cancer Clinic, we have been extremely successful in enrolling patients to clinical trials requiring research biopsies.
3) Develop and perform hypothesis-driven, translational clinical trials with biologically-based targeted therapeutics that are based on preclinical findings obtained in vitro and/or in vivo in human and murine systems, to address the most important issues in breast cancer .

My research endeavors are focused on the role of the following correlated key cell signaling pathways in breast cancer: PI3K/Akt, erbB (EGFR, HER2/neu), and Insulin-like Growth Factor (IGF)-1 pathways. I have developed targeted-oriented clinical trials addressing the role of these pathways in the development of resistance to antiestrogens and trastuzumab, as well as their role in triple-negative, basal-like tumors. This strategy will provide better understanding of breast cancer biology and of the molecular determinants of clinical efficacy, by optimally characterizing the molecular features of the breast cancer to be treated. This will foster target-assay development in a more limited number of patients. In turn, these results will be instrumental in expediting subsequent development of molecularly targeted agents, providing a platform for prioritization of novel combinations and elucidation of preferential mechanisms of escape from these therapies.

Examples of some of my investigator-initiated clinical trials include:

VICCBRE0949: A phase I/II study of cisplatin, paclitaxel and RAD001 in patients with metastatic breast cancer

VICCBRE0904: A phase II neoadjuvant study of cisplatin, paclitaxel with or without RAD001 in patients with triple-negative locally advanced breast cancer

VICCBRE09112: A phase II trial of endocrine therapy in combination with OSI-906 (an IGF-1R inhibitor) and erlotinib (Tarcevaâ„¢, an EGFR inhibitor) in patients with hormone-sensitive metastatic breast cancer

VICCBRE0942: A pre-surgical trial of metformin in patients with operable early breast cancer

VICCBRE0983: A Prospective Clinical Trial evaluating Potential Biomarkers for Bevacizumab Induced Hypertension
