  Purpose

The current study investigates Welchol as monotherapy to improve glycemic control in subjects with Type 2 Diabetes Mellitus not adequately controlled with diet and exercise alone. The study will evaluate if Welchol monotherapy for Type 2 Diabetes Mellitus will be safe, well tolerated and efficacious.
