Ravi Thadhani, MD, MPH I am a Professor of Medicine at Harvard Medical School, Chief of Nephrology at Massachusetts General Hospital, and Executive Director of the Clinical Trials Office at Partners Health Care. I have been at the MGH since 1991 and in the Division of Nephrology since 1994. My major activities include clinical and translational research, teaching and mentoring, and administrative responsibilities. My research efforts are divided into two main areas: Pregnancy and Dialysis. Pregnancy related studies have centered on human studies supporting basic science collaborations in the area of angiogenic factors and preeclampsia. We have developed a diagnostic test for preeclampsia that is currently in the clinic in Europe. I have now turned my attention to therapy for preeclampsia, and I am actively planning randomized trials based on our extensive collaborative work.

In the area of Dialysis, I have performed studies examining the effect of vitamin D in the survival of chronic hemodialysis patients. In a sustained series of studies, our links between vitamin D and dialysis survival have now been confirmed by over a dozen independent investigators world-wide. Clinical practices (academic and non-academic) have implemented practice patterns aligned with this work, and national and international practice guidelines have highlighted my series of studies.

Importantly, acknowledging the observational nature of this work, I pursued animal models of heart disease and the effect of vitamin D on preventing cardiac hypertrophy together with basic science collaborators. Our series of human and animal studies led to investigator initiated (Thadhani, PI) multicenter multinational clinical trials in patients with kidney disease. PRIMO is the first randomized trial in nephrology to test the hypothesis that active vitamin D therapy favorably affects cardiac hypertrophy. Our observational studies and subsequent in-vitro work focusing on the potential immuno-modulatory roles of vitamin D led us initiate DIVINE, which is a randomized trial in chronic hemodialysis subjects to test whether nutritional vitamin D therapy reduces the risk of infection. This multi-center translational trial focuses on different doses of nutritional vitamin D (ergocalciferol) and placebo, and we will closely examine rates of infection and ex-vivo examination of white cell responses to exogenous LPS and bacterial toxins. This is the first such trial in Nephrology.

I have also mentored numerous fellows and junior faculty members, all of whom have had a strong track record of publications and grant support, and many of whom are on faculty at leading institutions around the country.

Sagar Nigwekar, MD, MMSc is an Assistant Professor of Medicine at the Harvard Medical School and an Assistant in Medicine at the Massachusetts General Hospital. Dr. Nigwekar conducts translational research in the areas of calciphylaxis (calcific uremic arteriolopathy) and vascular calcification. He also has research interests in improving olfaction/malnutrition in patients with kidney disease and approaches to prevent nephrolithiasis. Dr. Nigwekar is the PI on multiple clinical trials including for VitK-CUA (NCT02278692), the first randomized trial for calciphylaxis patients. Dr. Nigwekar has been a prior recipient of Young Investigator Award from the National Kidney Foundation and Clinical Scientist in Nephrology award from the American Kidney Fund.

Sahir Kalim, MD, MMSc I am an Assistant Professor of Medicine at the Harvard Medical School and an Assistant in Medicine at the Massachusetts General Hospital. My academic focus involves understanding the fundamental mechanisms of the excess morbidity and mortality seen in chronic kidney disease (CKD) in order to develop new diagnostics and therapies for CKD patients. Our team has studied novel protein and metabolite alterations that occur in uremia and contribute to adverse outcomes. We have revealed the harmful effects of protein carbamylation on dialysis patients and how novel therapeutics including amino acid therapy can attenuate this process. This research has translated into first-in-human clinical studies and ultimately a randomized clinical trial. These studies have received generous support through entities such as the National Kidney Foundation Young Investigator Award and through an NIH K23 Career Development Award.
