Beschrijving
Inclusion Criteria:
- Women and men 50 years of age or older.
- Serum Sodium ≥123 and ≤ 134 mEq/L [mmol/L]at screening and baseline.
- Subjects with serum sodium concentrations ≥118 and ≤122 mEq/L[mmol/L] at screening and baseline may be entered into the trial based on consultation and approval from the study medical monitor.
Exclusion Criteria:
- Conditions or history which may present a safety concern to the subject or their offspring or extreme susceptibility to hypotension with sudden fluid loss (aquaresis).
- Hyponatremia that is acute, easily reversible, artifactual, or due to a condition not associated with vasopressin excess or likely to respond to aquaretic therapy.
- Conditions associated with an independent imminent risk of morbidity and mortality.
- Conditions which may confound the assessment of endpoints, history of poor compliance, participation in a clinical trial believed by the PI or Sponsor likely to confound endpoint assessments.
- Conditions which may confound primary endpoints of cognitive function.

Values: under 10 sec (no difficulties), 10 to 20 sec (starting to have balance difficulty), over 30 sec (at high risk for falls and dependent in most activities of daily living and mobility); test assesses risk to elderly subjects of falling and higher scores in seconds indicate higher risk of falling; ITT population

Change From Baseline in Postural Stability Test
Tijdsspanne: baseline and Day 22
|
Change from baseline to Day 22 in Postural Stability Test Z-score (This test measures gross motor control.
The ability to stand upright without moving is assessed using the SWAY meter that is modeled on the Wright Ataxiameter.
A cord from the meter is attached to the subject who is required to stand as still as possible with feet apart and eyes closed for 1 minute.
The test is then repeated with eyes open for 1 minute.
The outcomes of these tests are combined and measured as a movement Z-score.
Higher result=better postural stability); ITT population
