I have worked for many years in the area of translational and clinical investigation focused on the Myelodysplastic Syndrome and leukemia. This has involved drug development for an orphan disease in a multi-institutional national Cooperative Group, The Cancer and Leukemia Group B. I served as Principal Investigator for three successive trials; two phase I/II studies which demonstrated clinical activity of azacitidine in MDS and then a randomized phase III study of azacitidine compared to supportive care demonstrating azacitidine superiority. These three trials led to the approval of azacitidine by the FDA as the first drug approved for this disease. The treatment I helped pioneer, develop and test at Mount Sinai and in the Cancer Cooperative Groups and an International Consortium has changed the face of treatment of the Myelodysplastic Syndrome. It has improved the outcomes for tens of thousands of patients and their families around the globe. Based on our studies, azacitidine has become the standard of care for patients with higher-risk MDS and represents an important treatment option for older patients with Acute Myeloid Leukemia. These studies have established Mount Sinai as a center of expertise for MDS, and we are currently studying new therapeutic approaches to MDS including the development of novel agents. The approach we pioneered demonstrated that epigenetic therapy, one that can reprogram cells, could be clinically effective in MDS and some forms of AML. Cell reprogramming is now being tested in other diseases to modulate gene expression and cellular behavior. 

We conduct a variety of clinical and translational trials in patients with MDS, and investigate different approaches given the nature and heterogeneity of the disease. It is important to individualize therapy to each patient we treat based on the particular characteristics of the disease. The results of some of our studies provide leads, which will help enhance treatments for MDS in the future. I also contribute to leadership in other research groups, serving as Member of the Board of Directors of the Alliance for Clinical Trials in Oncology, a National Cancer Institute Designated Cooperative Cancer Clinical Trials Group and as a Member of the Board of Medical and Science Advisors of The Myelodysplastic Disease Foundation. We have established a Translational Research Center at Mount Sinai, for which I serve as the Director, and we are bringing in new investigators to work collaboratively to develop new strategies to overcome the challenges in the treatment of MDS, and to help find a cure for one of the most challenging diseases.

Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).

Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.
