Drug: Sugar Substitute Splenda
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)

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.
