Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy

Demonstrate the efficacy of urea therapy in correcting persistent hyponatremia despite adequate management (Appendix 2), during SAH.

Secondary objectives 7

  1. Compare the sodium intake required to correct natraemia
  2. Study the mechanism of action of urea
  3. Assess the impact of treatment on length of stay
  4. Evaluate the impact of treatment on neurological outcome at 3 months from inclusion
  5. Assessing adverse effects of treatment
  6. Persistence of natraemia correction 48H after discontinuation of treatment
  7. Comparison of speed of correction of natraemia

Conditions and MedDRA coding

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 2

  1. Patients aged 18 and over
  2. Non-traumatic SAH: Hyponatremia defined by a natraemia of less than 135 mmol/L and a high natriuresis, greater than 250 mmol/J despite well-managed salt intake.

Exclusion criteria 9

  1. Severe cardiac decompensation (LVEF < 30%)
  2. Severe hepatic cirrhosis (PT < 30%, ascites), known severe renal insufficiency (GFR < 30mL/min/1.73m²)
  3. Blood urea > 25 mmol/L in basal state
  4. Osmotherapy and diuretics in the last 48 hours
  5. Ongoing treatment with systemic corticosteroids
  6. Persons covered by articles L1121-5 to L1121-8 of the CSP, corresponding to all protected persons: pregnant women, parturients, nursing mothers, persons deprived of their liberty by judicial or administrative decision, persons not subject to a legal protection measure.
  7. Patient not affiliated to a social security scheme
  8. Known hypersensitivity to any component of ergytonyl
  9. Contraindications to ergytonyl: currently taking curative anticoagulants, previously known and treated diabetic patients

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Change in natraemia in mmol/L measured before and on day of treatment discontinuation

Secondary endpoints 7

  1. Compare the sodium intake required to correct natraemia
  2. Study the mechanism of action of urea
  3. Évaluer l’impact du traitement sur la durée de séjour
  4. Évaluer l’impact du traitement sur le devenir neurologique à 3 mois de l’inclusion
  5. Assessing adverse effects of treatment
  6. Persistence of natraemia correction 48H after discontinuation of treatment
  7. Comparison of speed of correction of natraemia
