Primary Outcome Measures:
  • Change From Baseline in Glycosylated Hemoglobin A1C (A1C) at Week 24 [ Time Frame: Baseline and 24 weeks ] [ Designated as safety issue: No ]
    Week 24 A1C minus baseline (Week 0) A1C. The unit for A1C is "percent". Thus, this measure represents a difference of percent values.
