Overview
Brief Summary
The goal of this study is to assess whether canagliflozin has a renal and vascular protective effect in reducing the progression of renal impairment relative to placebo in participants with type 2 diabetes mellitus (T2DM), Stage 2 or 3 chronic kidney disease (CKD) and macroalbuminuria, who are receiving standard of care including a maximum tolerated labeled daily dose of an angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB).
Detailed Description
This is a randomized (the study medication is assigned by chance), double-blind (neither physician nor participant knows the identity of the assigned treatment), placebo-controlled (an inactive substance that is compared with a medication to test whether the medication has a real effect), parallel-group, multicenter study of the effects of canagliflozin on renal and cardiovascular outcomes in participants with type 2 diabetes mellitus (T2DM) and diabetic nephropathy, who are receiving standard of care including a maximum tolerated daily dose of an angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB). The study will consist of a pretreatment phase (several weeks), and a double-blind treatment phase (up to approximately 66 months). During the pretreatment phase all participants will also receive diet/exercise counseling for lipid and blood pressure management as well as counseling on renal and cardiovascular (CV) risk factor medication. A post-treatment follow-up contact or visit will take place approximately 30 days after the last dose of study drug or the completion of the study. The total duration of the study is estimated to be about 5 to 5.5 years. Approximately 4,200 participants will be randomized in a 1:1 ratio to canagliflozin or matching placebo. Participants randomized to canagliflozin will receive a dose of 100 mg once daily. The overall safety and tolerability of canagliflozin will be evaluated by collecting information on adverse events, laboratory tests, vital signs (pulse, blood pressure), physical examination, and body weight.

Outcomes
Primary Outcomes
Primary Composite Endpoint of Doubling of Serum Creatinine (DoSC), End-stage Kidney Disease (ESKD), and Renal or Cardiovascular (CV) Death
Time Frame: Up to 4.6 years
Primary composite endpoint is the composite of DoSC, ESKD, and renal or CV death. DoSC: from baseline average determination (sustained and confirmed by repeat central laboratory measure after at least 30 days and preferably within 60 days). ESKD: as initiation of maintenance dialysis for at least 30 days, or renal transplantation, or an estimated glomerular filtration rate (eGFR) value of less than (\<)15 milliliters per minute per 1.73 square meter (mL/min/1.73 m\^2) (sustained and confirmed by repeat central laboratory measure after at least 30 days and preferably within 60 days). Renal death: death in participants who had reached ESKD, died without initiating renal replacement therapy, and no other cause of death was determined via adjudication. Adjudication of these events by Endpoint Adjudication Committee (EAC) was performed in blinded fashion. Event rate estimated based on time to first occurrence of primary composite endpoint are presented.
Secondary Outcomes
- Composite Endpoint of CV Death and Hospitalized Heart Failure (HHF)(Up to 4.6 years)
- Major Adverse Cardiac Event (MACE)(Up to 4.6 years)
- Hospitalized Heart Failure (HHF)(Up to 4.6 years)
- Renal Composite Endpoint(Up to 4.6 years)
- All-cause Mortality(Up to 4.6 years)
- Cardiovascular (CV) Death(Up to 4.6 years)
- CV Composite Endpoint(Up to 4.6 years)
