Primary Outcome Measures :
  1. Time to First Occurrence of Any Component Event of Composite (All-Cause Death, Nonfatal Myocardial Infarction (MI), Nonfatal Stroke, Coronary Revascularization, or Heart Failure Events) [ Time Frame: Up to 5 Years ]
    Time to first occurrence of any component event of composite, all-cause death, nonfatal MI, nonfatal stroke, coronary revascularization, or heart failure events that results in hospitalization or urgent visits.

Secondary Outcome Measures :
  1. Time to Onset of Type 2 Diabetes (T2D) [ Time Frame: Up to 5 Years ]
  2. Hierarchical Composite of Renal Death or End-Stage Renal Disease (ESRD), Sustained Decline in Estimated Glomerular Filtration Rate (eGFR), and eGFR Slope [ Time Frame: Estimated from Baseline (Week 0) to Study Completion Up to 5 Years ]
    Hierarchical composite of time to first occurrence of renal death or ESRD, ≥57% sustained decline in eGFR, ≥40% sustained decline in eGFR, and eGFR slope difference >0.5 milliliter/minute/1.73 square meter/year (mL/min/1.73 m²/year) will be assessed by the win ratio. The reported unit will be the total "wins" for each treatment group from performing a hierarchical comparison of components.

  3. Time to First Occurrence of Any Component Event of Major Adverse Cardiovascular Events-3 (MACE-3) (CV Death, Nonfatal MI or Nonfatal Stroke) [ Time Frame: Up to 5 Years ]
    Time to first occurrence of any component event of MACE-3 (CV death, nonfatal MI or nonfatal stroke)

  4. Mean Change from Baseline Short Form-36 Version 2 (SF-36 v2) Acute Form Physical Functioning Domain Score [ Time Frame: Baseline, 2 Years ]
    The SF-36 v2 acute, 1-week recall version is a 36-item generic, participant-administered measure designed to assess the following 8 domains (Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role - Emotional, and Mental Health. Each domain is scored individually and further aggregated into 2 health component summary scores, physical component and mental component summary. Scoring of each domain and both summary scores are norm-based and presented in the form of T-scores, with a mean of 50 and standard deviation of 10; higher scores indicate better levels of function and/or better health.

  5. Time to the Occurrence of All-cause Death [ Time Frame: Up to 5 Years ]
  6. Time to First Occurrence of CV Death [ Time Frame: Up to 5 Years ]
  7. Time to First Occurrence of MI [ Time Frame: Up to 5 Years ]
  8. Time to First Occurrence of Stroke [ Time Frame: Up to 5 Years ]
  9. Time to First Occurrence of Coronary Revascularization [ Time Frame: Up to 5 Years ]
  10. Time to First Occurrence Heart Failure (HF) Events [ Time Frame: Up to 5 Years ]
    Time to first occurrence heart failure (HF) events that result in hospitalization or urgent visits

  11. Time to First Occurrence of Hospitalization for Unstable Angina [ Time Frame: Up to 5 Years ]
  12. Time to first occurrence of Hospitalization or Urgent Visit [ Time Frame: Up to 5 Years ]
    Time to first occurrence of hospitalization or urgent visit due to atrial fibrillation, or cardioversion or ablation for atrial fibrillation

  13. Time to First Occurrence of Any Component Event of the Composite Endpoint (eGFR, ESRD, or Renal Death) [ Time Frame: Up to 5 Years ]
    Time to first occurrence of any component event of the composite endpoint ≥40% sustained decline in eGFR, ESRD, or renal death.

  14. eGFR Slope [ Time Frame: Up to 5 Years ]
  15. Percent Change from Baseline in Body Weight [ Time Frame: Baseline, 156 Weeks ]
  16. Change from Baseline in Systolic Blood Pressure (SBP) in Millimeter Mercury (mmHg) [ Time Frame: Baseline, 156 Weeks ]
  17. Change from Baseline Diastolic Blood Pressure (DBP) (mmHg) [ Time Frame: Baseline, 156 Weeks ]
  18. Percentage of Participants with Hemoglobin A1c (HbA1c) <39 Millimole/Mole (mmol/mol) (5.7%) [ Time Frame: Up to 5 Years ]
    Percentage of participants with HbA1c <39 mmol/mol (5.7%) at each time where HbA1c is assessed for participants with a screening HbA1c ≥39 mmol/mol.
