Including e.g., transurethral resection for BOO or Benign Prostatic Hyperplasia (BPH), hysterectomy or female incontinence procedures 8. Genito-urinary tract pathology that can in the investigator’s opinion be responsible for urgency or urinary incontinence e.g., symptomatic or recurrent urinary tract infections, interstitial cystitis, bladder-related pain, or stone in the bladder or urethra causing symptoms 9. A history of cancer with the last date of disease activity/prescence of malignancy within the last 12 months prior to Visit 1, except for adequately treated basal cell carcinoma of the skin 10.

Habitual (fluid intake >3L per day) or psychogenic polydipsia 12. Uncontrolled hypertension, as judged by the investigator 13. Uncontrolled diabetes mellitus, as judged by the investigator 14. Central or nephrogenic diabetes insipidus 15. Known history of Syndrome of Inappropriate Antidiuretic Hormone (SIADH) secretion 16. History of gastric retention 17. Known or suspected cardiac insufficiency or other conditions associated with fluid overload, sufficient to require treatment with diuretics, including a history of such conditions 18. Hyponatraemia (serum sodium level <135 mmol/L) at Visit 1 (re-tested and confirmed, with results available within 7 days) 19. Renal insufficiency (estimated glomerular filtration rate ≤60 mL/min) 20. Hepatic and/or biliary diseases: - Child-Pugh Class A, B, or C - Aspartate aminotransferase and/or alanine aminotransferase levels ≥2x the upper limit of normal range - Total bilirubin level >1.5 mg/dL 21. Known history of hypersensitivity to desmopressin ODT 31. Use of any prohibited therapy listed below: - Current or former (within 3 months prior to screening) treatment with any other IMP - Unstable electrostimulation or behavioural bladder training program less than 3 months prior to screening (stable electrostimulation or behavioural bladder training program started at least 3 months before screening are acceptable) - Thiazide diuretics - V2-receptor antagonists/agonists (e.g., vaptans/desmopressin, vasopressin) - Loperamide - Botulinum toxin (cosmetic non-urological use is acceptable) - Valproate 32. Subjects with a known history of type IIB or platelet-type (pseudo) von Willebrand's disease (because of the risk of platelet aggregation and thrombocytopenia). 33. Subjects with existing medical conditions, which lead to sodium losing states such as nausea, bulimia, anorexia nervosa, chronic vomiting, diarrhoea, adrenocortical insufficiency and salt losing nephropathies. |
