The impaired AVP regulation leads to water retention and secondary natriuresis and is a common cause for hyponatremia.\n\nEspecially chronic (\\>72h) SIADH is difficult to treat as standard therapeutic options (water restriction, urea, salt tablets) often do not succeed in correction of hyponatremia, making additional therapy necessary.\n\nEmpagliflozin is a sodium glucose co-transporter 2 (SGLT2)-inhibitor, which is a well-tolerated treatment option for type 2 diabetes mellitus. The inhibition of SGLT2 in the proximal tubule leads to renal excretion of glucose with subsequent osmotic diuresis. This mechanism could result in a therapeutic effect in patients with chronic SIADH, as it resembles the aquaretic effect of urea.\n\nThe aim of this study is to evaluate whether empagliflozin has an effect on the serum sodium levels of patients with chronic SIADH.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\nAdult patients (age ≥ 18 years) with hyponatremia (\\<133mmol/l) due to chronic (\\>72h) SIADH defined as\n\n* serum osmolality \\<275mosm/kg\n* urine osmolality \\>100mosm/kg\n* urine sodium \\>30mmol/l\n\nExclusion Criteria:\n\n* acute (\\<72h) or transient hyponatremia\n* severe symptomatic hyponatremia in need of hospital treatment\n* diabetes mellitus type 1\n* uncontrolled hypothyroidism\n* uncontrolled adrenal insufficiency\n* renal impairment (GFR \\<45ml/min)\n* cardiac failure\n* symptomatic liver disease / severe hepatic impairment (ALAT / aspartate transaminase (ASAT) \\> 3x upper limit)\n* treatment with SGLT 2 inhibitors, lithium chloride, urea or glitazone\n* severe immunosuppression\n* pregnancy or breastfeeding\n* palliative situation (end of life care)'}, 'identificationModule': {'nctId': 'NCT03202667', 'acronym': 'SANDx', 'briefTitle': 'Effects of the SGLT2-inhibitor Empagliflozin on Patients With Chronic SIADH - the SANDx Study', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital, Basel, Switzerland'}, 'officialTitle': 'Effects of the SGLT2-inhibitor Empagliflozin on Patients With Chronic SIADH - the SANDx Study', 'orgStudyIdInfo': {'id': '2017-00701'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Empagliflozin', 'description': 'Treatment with empagliflozin 25mg tablets once daily for 28 days', 'interventionNames': ['Drug: Empagliflozin 25mg']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': 'Treatment with Placebo tablets once daily for 28 days', 'interventionNames': ['Drug: Placebo']}], 'interventions': [{'name': 'Empagliflozin 25mg', 'type': 'DRUG', 'description': 'Treatment with empagliflozin 25mg once daily for 28 days', 'armGroupLabels': ['Empagliflozin']}, {'name': 'Placebo', 'type': 'DRUG', 'description': 'Treatment with Placebo oral tablet once daily for 28 days', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'zip': '4031', 'city': 'Basel', 'country': 'Switzerland', 'facility': 'University Hospital Basel', 'geoPoint': {'lat': 47.55839, 'lon': 7.57327}}], 'overallOfficials': [{'name': 'Mirjam Christ-Crain, Prof. Dr. MD', 'role': 'STUDY_DIRECTOR', 'affiliation': 'University Hopsital Basel'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University Hospital, Basel, Switzerland', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
