The INSIGHT study (Implementing New Strategies with Insulin Glargine for Hyperglycemia Therapy), presented at the 65th American Diabetes Association Annual Meeting and Scientific Sessions by lead investigator, Dr. Hertzel Gerstein, a professor of medicine and director of endocrinology and metabolism at McMaster University in Hamilton, demonstrated that early addition of insulin glargine therapy (in combination with oral agents or alone) safely achieved better glycemic and metabolic outcomes than adding oral agents. These results were achieved with no increased risk of hypoglycemia (low blood sugar levels) compared to oral medications.
"Often, insulin therapy is considered as a last resort during late-stage disease," said Dr. Gerstein. "What INSIGHT has shown is that basal insulin therapy with insulin glargine can be safely and effectively introduced early in the course of diabetes. These results may help change the way that type 2 diabetes is managed in the future."
All patients in the study had an A1C (target glycemic level) between seven and 11 per cent. This is above the recommended target of seven per cent or less, established by the Canadian Diabetes Association in the 2003 Clinical Practice Guidelines for the Prevention and Management of Diabetes in Canada. When insulin glargine was added to their treatment, patients were able to achieve lower and steady blood glucose levels more quickly and more often.
