About this study
SGLT2 inhibitors have demonstrated to mitigate cardiorenal risk in people with type 2 diabetes and are likely to play an increasingly large role in the treatment of patients with diabetes, chronic kidney disease and hypertension. Yet the underlying mechanisms of its protective effects are incompletely understood and the salutary effect may be altered by dietary factors such as sodium intake. Therefore, carefully designed mechanistic trials are needed to better understand the interplay between ertugliflozin and salt intake and to potentially modify salt intake to maximize treatment response. In addition, the study could contribute to hypotheses concerning the effects of SGLT2 inhibitors in combination with other drugs that affect sodium homeostasis and could help to explain the differences in kidney outcomes observed in (outcome) trials, which include different ethnicities with potential differences in dietary habits.

You may not qualify if…
- ✕ History of unstable or rapidly progressing renal disease NL80772.029.22 / DC2022ERTU DESIGN Protocol DESIGN, Study NO. 2022.0737 Version 5.0dd22-02-2024 14 of 45
- ✕ Estimated GFR \<60 mL/min/1.73m2 or eGFR \> 90 mL/min/1.73m2 determined by CKD-EPI
- ✕ UACR \> 30 mg/mmol
- ✕ Current/chronic use of the following medication: SGLT2 inhibitors, TZD, GLP-1RA, glucocorticoids, immune suppressants, antimicrobial agents, chemotherapeutics Participants should be on a stable dose of antipsychotics, tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs). Subjects on diuretics will only be excluded when these drugs cannot be stopped for the duration of the study.
- ✕ Chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) will not be allowed, unless used as incidental medication (1-2 tablets) for non-chronic indications (i.e.
- ✕ sports injury, headache or back ache). However, no such drug can be taken within a timeframe of 2 weeks prior to renal testing
- ✕ History of diabetic ketoacidosis (DKA) requiring medical intervention (e.g. emergency room visit and/or hospitalization) within 1 month prior to the Screening visit.
- ✕ Current urinary tract infection and active nephritis
