Summary:

      The purpose of this study is to learn if BMS-477118 (Saxagliptin) as part of a triple
      combination therapy can improve (decrease) hemoglobin A1c in patients with type 2 diabetes
      after 24 weeks of treatment compared to a 2 drug oral antidiabetic therapy. The safety of
      this treatment will also be studied.

                  hematuria microscopic urinalysis performed by the central laboratory.

                  NOTE: Female subjects with hematuria can be entered into the open-label phase and
                  be randomized, but should be investigated according to local standards and best
                  clinical practices. (See Appendix 3)

             cytochrome P450 3A4/5 inhibitors (in countries where dose adjustment would be required
             by the local saxagliptin label).

          5. Sex and Reproductive Status

             a) Women who are pregnant
