Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Body weight | from Day 1 to Day 9 | Change from baseline |
Other
| Measure | Time frame | Description |
|---|---|---|
| Treatment-emergent Adverse Events | From Day 1 up to End-of-Study (i.e. for at least 25 days) | Number of subjects with Adverse Events |
| Treatment-emergent Serious Adverse Events | From Screening (Day -3) up to Follow-up (i.e. for at least 49 days) | Number of subjects with Serious Adverse Events |
| Glomerular filtration rate (GFR) | At 0 h of Day 1, at 1 h, 2 h, 4 h, 6 h and 10 h of Day 1 & Day 9 | Change from baseline to each scheduled timepoint |
| Fractional sodium excretion in 24 h urine samples [mmol per day] | At 0 h of Day 1, at 1 h, 2 h, 4 h, 6 h and 10 h of Day 1 & Day 9 | Fractional excretion will be calculated as the clearance of sodium divided by the clearance of creatinine. Change from baseline to each scheduled timepoint |
| Fractional lithium excretion in 24 h urine samples [mmol per day] | At 0 h of Day 1, at 1 h, 2 h, 4 h, 6 h and 10 h of Day 1 & Day 9 | Fractional excretion will be calculated as the clearance of lithium divided by the clearance of creatinine. Change from baseline to each scheduled timepoint |
