Brief Summary:

The Investigator hypothesize that Dapagliflozin will improve EPC number and function AND Saxagliptin in addition to Dapagliflozin (additive effect) may improve EPC number and function even more than Dapa alone, compared to placebo.

The Investigator propose a 3-arm randomized, parallel group, longitudinal study of 16-week intervention duration. Participants will be randomized to 3 groups:

Group A: Dapa (10 mg) + Saxa Placebo, Enroll n=15, retain n=12 Group B: Dapa (10 mg) + Saxa (5 mg), Enroll n=15, retain n=12 Group C: Dapa Placebo + Saxa Placebo, Enroll n=15, retain n=12

Condition or disease Intervention/treatment Phase
Diabetes Mellitus, Type 2 Cardiovascular Diseases Drug: Dapagliflozin 10mg Drug: Saxagliptin 5mg Drug: Placebo Oral Tablet Phase 4
