    Dr. Barash is an Assistant Professor of Medicine at the Icahn School of Medicine at Mount Sinai and a full time clinical faculty member of the Mount Sinai Beth Israel (MSBI) Division of Nephrology with a clinical focus on Autosomal Dominant Polycystic Kidney Disease.  She is the Director of the MSBI Polycystic Kidney Disease (PKD) Program.  The MSBI PKD Program mission is to provide excellent clinical care, conduct clinical research and lead patient education and outreach programs.  Dr. Barash has collaborated with the Department of Body Radiology to establish a method for magnetic resonance imaging (MRI) 3D kidney volume measurements, a cutting-edge technique to monitor PKD progression and response to therapy.  She is the MSBI Site Principal Investigator for the clinical trial of tolvaptan in chronic kidney disease due to PKD.  She has organized a PKD Patient Education Workshop to share with the New York PKD patients the important advances in management of PKD-related cardiovascular health, nutrition, chronic kidney disease, as well as research updates.

Dr. Barash’s research centers on Autosomal Dominant Polycystic Kidney Disease (ADPKD), focusing on translational studies and clinical therapeutic trials.  Dr. Barash’s advanced research training led to a Master of Science degree in Clinical Research from the Icahn School of Medicine at Mount Sinai.  She conducted and published a pilot clinical study of water loading to decrease levels of cAMP (a cyst growth signal) in ADPKD.  She currently serves as the MSBI Site Principal Investigator of the Phase 3b trial of tolvaptan efficacy for ADPKD.  This is a global trial that is addressing the efficacy of tolvaptan in slowing disease progression in ADPKD patients who have reduced kidney function.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Barash did not report having any of the following types of financial relationships with industry during 2015 and/or 2016: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company.
