Study TO Prevent Diabetes With Short-term Insulin Glargine Only

Not Applicable

• Conditions: Pre-diabetes

• Registration Number: NCT01276912
• Lead Sponsor: Beijing Tongren Hospital

Brief Summary

* Pre-diabetes is a significant risk factor for the development of type 2 diabetes, as well as macrovascular and microvascular complication.

* Previous studies show that 50% or more loss in islet B-cell function even in Pre-diabetes phase. The early insulin therapy in pre-diabetes may be a strategy in preventing metabolic disorders and cardiovascular disease.

* The objective of this study is to find if an initial insulin glargine intervention in pre-diabetes (IGT and /or IFG) could be a strategy in preventing type 2 Diabetes.

* Pre-diabetes subjects will receive a insulin glargine therapy with a dosage adjusted to get FBG ≤ 5.3mmol / L as the goal. Insulin glargine treatment will be maintained for three months thereafter to find if it can prevent diabetes.
