Abstract: Described herein are methods of treating acute heart failure in a subject in need thereof, comprising administering a therapeutically effective amount of istaroxime by intravenous infusion over a period of at least 24 hours wherein the therapeutically effective amount of istaroxime is between about 0.1 ?g/kg/min and about 3.0 g/kg/min; and wherein the subject's acute heart failure is treated.

Abstract: Compounds and compositions for the activation of SERCA2a are disclosed. In particular, provided are compounds that act as predominantly pure or pure SERCA2a activators while only moderately inhibiting the Na+/K+ ATPase. In general, the disclosed compounds are derivatives of androstane having the formula (I) Also disclosed herein are pharmaceutical compositions comprising one or more of the compounds of formula (I) for use for the treatment of heart failure.

Abstract: Compositions for intravenous infusion of istaroxime, or a metabolite of istaroxime, in human patients suffering from heart failure are disclosed. Likewise, methods for extended infusion of istaroxime or its metabolites in individuals with heart failure are disclosed. In particular, some methods disclosed herein include the infusion of istaroxime, or a metabolite thereof, for a period of time that is greater than six hours in order to improve cardiac relaxation without triggering arrhythmogenic events in an individual suffering from heart failure. Other methods include administration of istaroxime until certain plasma concentration thresholds of istaroxime metabolites are achieved. Also disclosed are istaroxime metabolites with selective SERCA2a activation.

Abstract: Disclosed are compounds of formula (I), wherein X, Y, Z are annular atoms comprised in a five-membered carbocyclic or heterocyclic ring, selected from the group consisting of CH, NH, N, O, S; said carbocyclic or heterocyclic ring being optionally substituted with amino (C1-C4) linear or branched alkyl or guanidine or guanidino (C1-C4) linear or branched alkyl; with the proviso that the heterocycle ring is not furyl; n is 0 or 1; R is H or OH; the dotted line represents an optional double bond C?C; the thick line represents a bond in the ? configuration; the wavy line represents a bond both in the ? and ? configuration; their enantiomeric and/or diastereomeric mixtures, their pharmaceutically acceptable salts, their solvates, hydrates; their metabolite and metabolic precursors. The compounds of formula (I) are for use as medicaments, in particular for the treatment of acute or chronic heart failure. Oral administration is also possible.
