Effects of the SGLT2-inhibitor Empagliflozin on Patients With SIADH - the SAND Study

Plain-language summary
Syndrome of inappropriate antidiuresis (SIADH) is characterized by an imbalance of antidiuretic vasopressin (AVP) secretion. The impaired AVP regulation leads to water retention and secondary natriuresis and is a common cause for hyponatremia.
The therapeutic options, aside from treating the underlying disease, depend upon the onset and severity of the symptoms and involve usually fluid restriction or hypertonic saline infusion. Alternative therapeutic options are loop diuretics, administration of oral urea or vasopressin receptor antagonists (vaptans). Despite those options, there are a considerable number of patients which do not sufficiently respond, making additional therapy necessary.
Empagliflozin (Jardiance)® is a sodium glucose co-transporter 2 (SGLT2)-inhibitor, which is a new treatment option developed for patients with diabetes mellitus type 2. The SGLT2 is expressed in the proximal tubule and reabsorbs approximately 90 percent of the filtered glucose. The inhibition of SGLT2 results in renal excretion of glucose with subsequent osmotic diuresis. This mechanism could result in a therapeutic effect in patients with hypotonic hyponatremia as in SIADH.
The aim of this study is to evaluate whether empagliflozin (Jardiance)® has an effect on the serum sodium levels of patients with SIADH.

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?

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.
