E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To Assess the safety, tolerability and efficacy of two different doses of istaroxime (0.5 and 1.0 μg/kg/min), a new agent with lusitropic and inotropic activities that improves the cardiac contraction-relaxation cycle. The 2 doses of istaroxime (0.5 and 1.0 μg/kg/min) will be infused i. v. for 24 hours in comparison with placebo, in
treatment of Chinese and Italian patients with Acute Decompensated Heart
Failure. |
|
E.2.2 | Secondary objectives of the trial |
In all Italian patients and in a subset of Chinese patients pharmacokinetics and metabolism of istaroxime shall also be studied |
|

E.5.2 | Secondary end point(s) |
Efficacy:
• Change from baseline to 24 hours in the treatment period Day1 (addressing the differences between the changes at 6 and 24 hours from baseline) of the following Echo-Doppler parameters:
- LV Ejection fraction (EF)
- LV end systolic and end diastolic volumes
- Stroke volume index (SVI)
- E, A and E/A ratio
• Difference between the changes at 6 and 24 hours from baseline of the
Tissue Doppler parameter E/Ea
• Others Tissue Doppler parameters such as Sa, Da and Aa
• Changes in dyspnoea assessed at 3, 6, 12, 24, 48 hours after infusion start by Visual Analog Scale (VAS) (including only patients presenting dyspnoea at baseline);
• Area under the curve (AUC) on changes in dyspnoea assessed at 3, 6, 12, 24, 48 hours after infusion start by VAS (including only patients presenting dyspnea at baseline);
• Changes in BNP from baseline at 24 hours;
• Proportion of patients with hospital readmissions or emergency visits
for cardiovascular reasons by Day 30;
• Proportion of patients with episodes of worsening HF defined by the need to increase the dose or reinitiate i.v. therapy with diuretics and/ or other inotropic agents during the hospitalization;
• Length of the hospitalization.
Safety:
• Incidence of adverse events;
• Change in vital signs (including body temperature and dyspnoea);
• Change in 12-lead ECG parameters;
