E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- evaluate the safety and tolerability of an iv serelaxin infusion in addition to standard of care in hospitalized pediatric patients with AHF.
- investigate the effects of age on the pharmacokinetics of serelaxin given as iv infusion in addition to standard of care in hospitalized pediatric patients with AHF |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the hemodynamic effects of different doses of serelaxin given as an iv infusion in addition to standard of care in hospitalized pediatric patients with AHF [efficacy parameters: arterial blood pressure, left atrial pressure (LAP), pulmonary artery pressure (PAP – systolic and diastolic), central venous and arterial oxygen saturation, urine output, and blood lactate levels]. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Investigation of possible correlations between the serelaxin exposure and PD effects through high-frequency data of continuously monitored clinical and hemodynamic parameters. (dated 20 August 2014, version 1)
Exploratory Objectives
• To explore the serelaxin PK-PD relationship using high-frequency data from patients enrolled in sites participating in the high-frequency data sub-study
• To explore the benefits, feasibility and resource requirements of automated high-frequency |
|
E.3 | Principal inclusion criteria |
1. Written informed consent by parent(s)/legal guardian(s) for the pediatric patient must be obtained before any study-specific assessment is performed
2. Male or female, birth to <18 years of age, with body weight ≥2.5 kg to ≤120 kg
3. Hospitalized in an intensive/critical care unit or continuously monitored step-down unit with the following:
a) signs and symptoms of AHF of any etiology
b) a stable dose of vasoactive and/or inotropic agents
c) for non-surgical patients (medical etiologies of AHF), echocardiographic evidence of reduced ventricular function is required as follows:
i.Ejection fraction of the systemic or pulmonary ventricle <50% in patients with systemic left ventricular dysfunction, or
ii.Fractional shortening <28% in patients with systemic left ventricular dysfunction, or
iii.Qualitative evidence of a dilated ventricle with at least mild systemic ventricular systolic dysfunction in patients with right ventricular or single ventricular physiology
4. Systolic blood pressure (SBP) consistently equal to or greater than the calculated 25th percentile SBP for age and gender per the protocol.
5. Stable pulmonary function, i.e. patient is extubated or is stable on ventilator support.
Additional details are listed in the clinical study protocol. |

(However, single ventricle patients post Glenn operation before their Fontan/Total cavopulmonary connection procedure (TCPC) can be enrolled.)
4. Patients on ECMO or VAD
5. Patients with fixed pulmonary hypertension
6. Patients with blood lactate levels >5 mmol/L at screening
7. Birth < 36 weeks post-conceptual age (applies only to children <1year old at baseline)

9. Dyspnea or acute lung injury primarily due to non-cardiac causes
10. Patients with severe renal impairment, those known to have significant renal disease and those having current or planned renal replacement therapy
11. Excessive use of inotropic and/or vasoactive agents at screening (vasoactive score >20)
12. Current or planned use of the following concomitant medications during the duration of the study drug infusion: levosimendan, nesiritide
13. History or current diagnosis of cardiac electrocardiographic abnormalities
14. Any major solid organ transplant recipient within 1 year of transplantation
15. Any major solid organ transplant recipient who presents with severe organ rejection |
