PRIMARY outcome

Timeframe: Baseline, Day 3 (48 hours)

Population: One participant in the Tolvaptan group missed study Visit 2 (Day 3 (48 hours)) due to adverse weather. This participant subsequently attended study Visit 3 (Day 8) to complete the study. Thus data were available on 18 of the 19 patients in the Tolvaptan group for this endpoint at study Visit 2 (Day 3 (48 hours)).

The primary endpoint for the study will be change in body weight between patients randomized to tolvaptan versus placebo from baseline to 48 hours

PRIMARY outcome

Timeframe: Baseline, Day 3 (48 hours)

Population: One participant in the High Copeptin - Tolvaptan group missed study Visit 2 (Day 3 (48 hours)) due to adverse weather. Thus data were available on 11 of the 12 patients in the High Copeptin - Tolvaptan group for this endpoint.

The primary endpoint for the study will be change in body weight between patients randomized to tolvaptan versus placebo from baseline to 48 hours with stratification for baseline copeptin level

Population: One participant in the Tolvaptan group missed study Visit 2 (Day 3 (48 hours)) due to adverse weather. This participant subsequently attended study Visit 3 (Day 8) to complete the study. Thus data were available on 18 of the 19 patients in the Tolvaptan group for this endpoint at study Visit 2 (Day 3 (48 hours)).

Changes in patient reported dyspnea scale from baseline to 48 hours based on the visual analog scale. Visual Analog Scale (VAS) - Patient Dyspnea has a minimum value of 0 and a maximum value of 100. Higher scores mean a better outcome.

SECONDARY outcome

Timeframe: Day 3 (48 hours)

Change in loop diuretic dose at 48 hours where doses of loop diuretic are expressed as furosemide milligram equivalents based on standard conversions of bumetanide and torsemide doses to milligram equivalents of furosemide. The formula for the conversion of doses of loop diuretics were standardized to milligram equivalents of furosemide based on 40 milligrams of furosemide for each 1 milligram of bumetanide and 2 milligrams of furosemide for each 1 milligram of torsemide.

SECONDARY outcome

Timeframe: Day 3 (48 hours)

Change in loop diuretic score defined by change in loop diuretic use at Visit 2. The change in loop diuretic score endpoint was calculated as follows: patients having an increase in loop diuretic use at Visit 2 were given a score of 2, patients with no change a score of 0, and patients with a decrease in loop use at Visit 2 were given a score of -1. Increases in loop diuretic use were given a higher weighting to account for their reflection of treatment failure.
