Placebo Controlled, Randomized, Double-blind, Multi-center Study to Investigate the Efficacy and Tolerability of BAY58-2667

This study has been terminated.

The purpose of this study is to assess a dose titration scheme, of a new drug (BAY58-2667) given intravenously, to evaluate if this is safe and can help to improve the well-being, symptoms (e.g. breathing) and outcome of decompensated heart failure. Patients living with chronic heart failure have a risk of increased number of hospitalisations because of worsening of their condition (decompensated heart failure). The current treatment of acute heart failure consists of oxygen and medical treatment with vasodilators and positive inotropic agents (drugs, which should strengthen the pump function of the heart) which have their limitations. Therefore there is a need for new drugs in treatment of acute heat failure.

Primary Outcome Measures:
  • The primary efficacy outcome measure will be the change of pulmonary capillary wedge pressure (PCWP) from baseline to 8 hours versus placebo. [ Time Frame: 8 hours ]

Secondary Outcome Measures:
  • Quality of Life [ Time Frame: Up to 30 days Follow-up ]
  • Rehospitalization [ Time Frame: Up to 30 days Follow-up ]
  • Other hemodynamic measurements [ Time Frame: Up to 48 hours ]
    Right atrial pressure (RAP); mean pulmonary artery pressure (PAP mean); pulmonary artery systolic pressure (PASP); pulmonary artery diastolic pressure (PADP); cardiac output (CO); cardiac index (CI); mean arterial pressure (MAP); pulmonary vascular resistance (PVR); pulmonary vascular resistance index (PVRI); systemic vascular resistance (SVR); and systemic vascular resistance index (SVRI)

  • Safety variables [ Time Frame: Up to 30 days follow up ]
    Treatment-emergent adverse events, laboratory parameters, renal function, in-hospital mortality, length of stay at intensive care unit, and 30-day mortality / morbidity.

  • Plasma concentrations [ Time Frame: During both the titration and maintenance phases were evaluated. ]
