The purpose of this trial was to evaluate the effectiveness and safety of Naturlose (Tagatose) for glycemic control in people with Type 2 diabetes who were not taking other medications for the condition and who were under diet control and exercise.

The study lasted approximately one year. HbA1c was monitored every 2 months after entry into the study. Safety and tolerance for tagatose were assessed every 2 months throughout the study. A total of 14 visits were made to the study site.

Drug: Sugar Substitute Splenda
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Primary Outcome Measures:
  • Change in Hemoglobin A1C Level From Baseline [ Time Frame: 1 year from baseline ]
    The primary efficacy variable will be the change in HbA1c level from baseline. Changes from baseline in HbA1c level at each visit will be assessed with the use of linear model(ANCOVA) to adjust for any baseline difference, as well as the stratification factor.

Enrollment: 494
Study Start Date: April 2007
Study Completion Date: October 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Sugar Substitute Splenda
1.5 g Sugar Substitute Splenda, dissolved in 125 ml of water three times per day. If intestinal problems occur, the dose should be reduced to 1 g dissolved in water tid or additionally reduced to 0.5 g dissolved in 125 ml of water tid if problems still persisted, until patients adapted to treatment.
Drug: Sugar Substitute Splenda
1.5 g powder tid
Experimental: Tagatose
15 g Tagatose dissolved in 125 ml of water three times a day. The Tagatose dosage will be decreased to 10 g dissolved in 125 ml of water tid or decreased additionally to 5 g Tagatose dissolved in 125 ml of water tid, if needed due to gastrointestinal effects, until patients adapt to the treatment
Drug: Tagatose
powder; 15 grams three times daily; one year
Other Name: Naturlose
