ABOUT THE COLLABORATIVE STUDY GROUP

The Collaborative Study Group (CSG), the largest standing renal clinical trials group worldwide, is comprised of academic and tertiary care physician- researchers interested in collaborative clinical trials investigating new therapeutic approaches in the treatment of kidney disease. Since 1979, the CSG has conducted multiple large-scale clinical trials resulting in over 40 major publications in peer-reviewed journals. The CSG conducted pivotal trials of ACE Inhibition in Type 1 Diabetic Nephropathy and of Irbesartan in Type 2 Diabetic Nephropathy (I.D.N.T.), both of which led to FDA product registration for new indications and the recommendation of these agents as standard of care by the American Diabetes Association. The results of each of the CSG's last three major clinical trials were published in the New England Journal of Medicine. The IDNT multi-national trial in collaboration with Bristol-Myers Squibb and Sanofi-Synthelabo is the largest trial in renal disease to date, consisting of 1,715 patients from 210 investigative sites worldwide. The CSG is currently conducting the pivotal clinical program for KRX-101, including both the Phase III and Phase IV studies.
