Valsartan delays progression to type 2 diabetes in IGT patients: NAVIGATOR study

October 26, 2017

Valsartan therapy did not show a reduction in the risk of cardiovascular events in this well-managed group of patients, while nateglinide-based therapy did not show a reduction in the incidence of new-onset diabetes or of cardiovascular events in this study population.

Trevor Mundel, M.D., Global Head of Development at Novartis Pharma AG said: "As a global leader in cardiovascular and metabolic health, Novartis is committed to advancing public health and policy pertaining to diabetes. We are very pleased with the findings of the NAVIGATOR study as they add to the large body of scientific information on valsartan."

The worldwide prevalence of diabetes is expected to increase by 50% (i.e. from 285 to 439 million patients) by 2030. IGT is a defined stage in the development of diabetes, and it has been suggested that up to 70% of people with impaired fasting glucose (IFG) and IGT are likely to develop type 2 diabetes over their lifetime. Current guidance from the American Diabetes Association, American College of Endocrinology/American Association of Clinical Endocrinologists and the World Health Organization recommends a variety of interventions for the management of pre-diabetes, based on lifestyle modification.

"Lifestyle modification remains the primary intervention for the prevention of diabetes. The NAVIGATOR study shows that valsartan, when added to a lifestyle-modification program, can delay progression to diabetes in people who are at high cardiovascular risk and have impaired glucose tolerance," said Dr Rury Holman, Professor of Diabetic Medicine at the Oxford Centre for Diabetes, Endocrinology & Metabolism, University of Oxford, United Kingdom.

Novartis plans to discuss the results of this study with the U.S. Food and Drug Administration with a view to applying for a label change for valsartan. Valsartan is currently indicated for the treatment of high blood pressure, for the treatment of heart failure, and reducing the risk of cardiovascular mortality in patients who have suffered a heart attack (myocardial infarction). Nateglinide is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes. Neither valsartan nor nateglinide is currently indicated for the treatment of patients with IGT.
