A Study to Explore the Efficacy of TRV027 in Patients Hospitalized for Acute Decompensated Heart Failure

To evaluate the overall safety and efficacy of TRV027 when administered in addition to standard of care (SOC) on mortality, morbidity, dyspnea, and length of stay in patients hospitalized with Acute Decompensated Heart Failure (ADHF).

   * Elevated jugular venous pressure (≥8 cm H2O)
7. Receipt of a IV loop diuretic at a minimum dose 40 mg furosemide (or equivalent loop diuretic) for the treatment of dyspnea due to ADHF at least 1 hour prior to anticipated randomization and the initiation of study medication
8. Patient report of dyspnea at rest or upon minimal exertion during screening at least one hour after administration of IV loop diuretic
