/ PRNewswire / — The first comprehensive long-term study comparing different medications for type 2 diabetes is launching nationwide.

The GRADE Study is sponsored by The National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health. It being coordinated by the Biostatistics Center, a research facility of The George Washington University.

“What differentiates GRADE from previous studies is that it will perform a head-to-head comprehensive comparison of the most commonly used drugs over a long period of time. This type of comparison has never been done before,” said David M. Nathan, MD, Director of the Massachusetts General Hospital Diabetes Unit, Professor of Medicine, Harvard Medical School and Chairman of the GRADE Study.

The GRADE Study will compare the effects of four glucose-lowering medications: the sulfonylurea, glimepiride; DPP-4 inhibitor, sitagliptin; GLP-1 agonist, liraglutide; and basal insulin, glargine; when each is added to metformin.

5,000 patients will be enrolled in up to 50 academic and VA medical centers nationwide. Patients will be followed for up to seven years. Participants will have their diabetes medications managed free of charge throughout the study, including at least four medical visits per year.

The GRADE Study ( number: NCT01794143) is supported under NIH grant U01DK098246.
