Further study details as provided by Novartis:

Primary Outcome Measures:
  • Time to confirmed cardiovascular (CV) death during the follow-up period of 180 days [ Time Frame: From baseline to 180 days ] [ Designated as safety issue: No ]
    Time-to-event is computed as the number of days from randomization to CV death.


Secondary Outcome Measures:
  • Time to all-cause death through Day 180 [ Time Frame: From baseline to 180 days ] [ Designated as safety issue: No ]
    Time to event is computed as the number of days from randomization to all cause death

  • Time to worsening of heart failure (WHF) through Day 5 (considering death in the 5-day [ Time Frame: From baseline to Day 5 ] [ Designated as safety issue: No ]
    Time to event is computed as the number of days from randomization to WHF

  • Length of total hospital stay (LOS) during the index acute heart failure (AHF) hospitalization [ Time Frame: From baseline to 180 days ] [ Designated as safety issue: No ]
    Length of stay will be defined as the index hospitalization discharge date and time minus the baseline date and time plus 1 day

  • Time to first occurrence of the composite endpoint of CV death or rehospitalization due to heart failure or renal failure through day 180 [ Time Frame: From baseline to 180 days ] [ Designated as safety issue: No ]
    Time to first is computed as the number of days from randomization to event of interest

  • Length of Intensive Care Unit (ICU) and/or Coronary care unit (CCU) stay for the index AHF hospitalization [ Time Frame: From baselint to 180 days ] [ Designated as safety issue: No ]
    Length of stay will be defined as the hospitalization discharge date and the time minus the baseline date and time plus 1 day

  • Change from baseline in congestive signs and symptoms of heart failure through Day 5 [ Time Frame: From baseline to Day 5 ] [ Designated as safety issue: No ]
    Change from baseline in congestive signs and symptoms of HF through Day 5 will be analyzed by displaying the change in percentage of patients by treatment and time points for each of the signs and symptoms variables.

  • Change from baseline in selected biomarkers from baseline through Day 14 in a subset [ Time Frame: From baseline to Day 14 ] [ Designated as safety issue: No ]
  • Number of patients reported with total adverse events, serious adverse events and death [ Time Frame: For the safety evaluation, all adverse events will be collected from signing of the informed consent form through Day 5 for non-serious AEs and through Day 14 for serious AEs. ] [ Designated as safety issue: Yes ]
    To evaluate the safety and tolerability of intravenous serelaxin in AHF patients, number of patients with total adverse events, serious adverse events and death will be analyzed.

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male or female 18 years of age, with body weight ≤160 kg
  • Hospitalized for AHF; AHF is defined as including all of the following measured at any time between presentation (including the emergency department) and the end of screening:

    • Dyspnea at rest or with minimal exertion
    • Pulmonary congestion on chest radiograph
    • BNP ≥350 pg/mL or NT-proBNP ≥1,400 pg/mL
  • Systolic BP ≥125 mmHg at the start and at the end of screening
  • Able to be randomized within 16 hours from presentation to the hospital, including the emergency department
  • Received intravenous furosemide of at least 40 mg total (or equivalent) at any time between presentation (this includes outpatient clinic, ambulance, or hospital including emergency department) and the start of screening for the study for the treatment of the current acute HF episode.

Exclusion Criteria:

  • Dyspnea primarily due to non-cardiac causes
  • Temperature >38.5°C (oral or equivalent) or sepsis or active infection requiring IV anti-microbial treatment
  • Clinical evidence of acute coronary syndrome currently or within 30 days prior to enrollment.
  • AHF due to significant arrhythmias, which include any of the following: sustained ventricular tachycardia, bradycardia with sustained ventricular rate <45 beats per minute, or atrial fibrillation/flutter with sustained ventricular response of >130 beats per minute
  • Patients with severe renal impairment defined as pre-randomization eGFR < 25 mL/min/1.73m2 calculated using the sMDRD equation, and/or those receiving current or planned dialysis or ultrafiltration

Other protocol defined inclusion/exclusion criteria may apply.
