Research Studies

Renal Disease Research Institute (RDRI) is a research entity affiliated with Dallas Nephrology Associates. For more than 50 years, Dallas Nephrology Associates has been caring for patients with kidney disease, hypertension, transplants and complicated electrolyte disorders. The Research Institute allows us to conduct clinical trials that will improve our future ability to treat kidney disease and give our patients the opportunity to receive cutting-edge therapy.  At RDRI, there is significant ethical oversight of this entity through RDRI’s Board of Managers and Scientific Review Committee.
