Molecular Mechanisms of SGLT2 Inhibition in Diabetic Kidney Disease
University of Colorado, Denver
Summary
Canagliflozin is an oral drug which is currently approved for use in patients with type 2 diabetes by the US Food and Drug Administration (FDA). Canagliflozin acts by increasing salt and sugar loss in the urine, and has shown to protect heart, kidney, and blood vessel function in patients with type 2 diabetes. However, it is unknown how canagliflozin protects the kidneys from disease. Therefore, this study plans to learn more about how canagliflozin works to protect against diabetic kidney disease in adults with type 2 diabetes. This study will use state-of-the-art kidney imaging, kidney biopsies and detailed testing of kidney function to determine the mechanisms of protection afforded by canagliflozin.
Description
The purpose of this protocol is to examine the effects of the sodium-glucose cotransporter 2 (SGLT2) inhibitor canagliflozin on intrarenal transcripts of energy metabolism in adults with type 2 diabetes and early diabetic kidney disease (DKD) via an open-label non-randomized mechanistic trial. This trial will enroll 40 participants who will receive 100 mg of canagliflozin daily for six (6) months in addition to standard of care. The primary objective of this study is to determine whether canagliflozin affects intrarenal transcripts of energy metabolism in adults with type 2 diabetes and early…

Inclusion Criteria: * Aged 18-80 years. The lower age limit was set so renal function test results would not reflect changes associated with growth. * Diagnosis of type 2 diabetes for ≥ 3 years. * Estimated GFR \>45 and \< 90 ml/min/1.73m2 as determined from the CKD-EPI equation using serum creatinine (Levey et al., 2009). * A screening urinary albumin-to-creatinine ratio \<3000 mg/g. * Willingness to participate after receiving a thorough explanation of the study. * Participants receiving a RAAS inhibitor must have been receiving the drug at maximum tolerable dose for at least 3 months prior…
Interventions
- Drugcanagliflozin
Canagliflozin is in a class of medications called sodium-glucose co-transporter 2 (SGLT2) inhibitors. It is a used to treat type 2 diabetes. Canagliflozin lowers blood sugars by causing the kidneys to excrete more glucose in the urine.

Diagnostic aid/agent used to measure renal plasma flow (RPF) PAH (Basic Pharma, Geleen, Netherlands) has been used to measure RPF in human research for 7 decades, and is very well tolerated and generally recognized as safe with low toxicity.
