DiEtary Sodium Intake Effects on Ertugliflozin-induced Changes in GFR, reNal Oxygenation and Systemic Hemodynamics: the DESIGN Study, a Randomized, Placebo-controlled, Cross-over Study With Ertugliflozin in People With Type 2 Diabetes

United States, Netherlands34 participantsStarted 2023-07-25

Plain-language summary

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
