This study is a six-month, prospective, randomized, multicenter, single- blind, controlled clinical study to evaluate the effect of three low-doses of Naturlose (Tagatose) on glycemic control and safety in subjects with Type 2 diabetes under diet control and exercise. The subjects will be randomized in one of the 3 arms receiving 2.5, 5 or 7.5 gm of Tagatose. This trial is already on-going in the USA, and is intended to be conducted at 25 investigational sites globally, including 8 sites in India.

Primary Outcomes

To evaluate the effect of three low-doses of Naturlose (tagatose) in the glycemic control of patients with Type 2 Diabetes Mellitus as measured by HbA1c at the end of 6 months of therapy using the patient's own baseline HbA1c levels as control.
time frame: 6 months

Secondary Outcomes

Effects of Naturlose (tagatose) on other glycemic control measurements such as plasma glucose concentrations and plasma lipids at each study visit
time frame: 6 months
A decrease of ≥0.5% in HbA1c level at each study visit
time frame: 6 months
A decrease of ≥1% in HbA1c level in any of the Naturlose (tagatose) treatment groups at any time point over the duration of the study
time frame: 8 months
A decrease of Fasting Plasma Glucose (FPG) level compared with baseline level at any time point over the duration of the study
time frame: 6 months
Body weight loss (compared to baseline)
time frame: 6 months
