Arm Label
Serelaxin
Arm Description
Serelaxin was administered intravenously on top of standard therapy for acute heart failure, for a total of 48 hours.
Outcomes
Primary Outcome Measures
Number of Patients With Treatment Emergent Adverse Events, Serious Adverse Events and Death
Number of patients with treatment emergent adverse events (including confirmed systolic blood pressure decreases and worsening heart failure), serious adverse events and death were reported.
Pharmacokinetic Concentration for Low Dose 3-10-30 ug/kg/Day
Pharmacokinetic (PK) concentration was presented as the surrogate for PK parameters, the original primary endpoint, due to the unavailability of the PK parameters Css and CL. Serelaxin concentration was determined in serum by a validated Enzyme Linked ImmunoSorbent Assay (ELISA) based upon the commercially available kit from R&D Systems (Catalogue No. DRL200). The ELISA method used a monoclonal antibody specific for human H2 relaxin as the capture reagent and an enzyme-linked polyclonal antibody specific for human.
Pharmacokinetic Concentration for High Dose (10-30-100 ug/kg/Day)
Pharmacokinetic (PK) concentration was presented as the surrogate for PK parameters, the original primary endpoint, due to the unavailability of the PK parameters Css and CL. Serelaxin concentration was determined in serum by a validated Enzyme Linked ImmunoSorbent Assay (ELISA) based upon the commercially available kit from R&D Systems (Catalogue No. DRL200). The ELISA method used a monoclonal antibody specific for human H2 relaxin as the capture reagent and an enzyme-linked polyclonal antibody specific for human.

5. Study Description
Brief Summary
The purpose of the study was to evaluate the safety, tolerability and pharmacokinetics of an intravenous infusion of serelaxin on top of standard of care therapy, in pediatric patients with acute heart failure (AHF)
Detailed Description
The study was terminated early and the pediatric development of serelaxin in the treatment of acute heart failure (AHF) discontinued, following the results of the phase III study RELAX-AHF-2 (CRLX030A2301/NCT01870778) study in adult patients with AHF. Whilst no new safety concerns associated with serelaxin were observed, the study in adults did not meet either of its primary endpoints
