About this study

Official title: Multicenter, Open-label, Dose Escalation Study to Evaluate Safety, Tolerability and Pharmacokinetics of RLX030 in Addition to Standard of Care in Pediatric Patients From Birth to <18 Years of Age, Hospitalized With Acute Heart Failure

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)

Read the 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

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: through 28 days + 30 days SAE follow up after completion or discontinuation from the study

  2. 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.

    Measured: at 0, 2, 16, 22, 32, 40, 48 hr. during the infusion, at 0.5, 4, 8 hours post infusion or study drug discontinuation, and on day 28

  3. 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.

    Measured: at 0, 2, 16, 22, 32, 40, 48 hr. during the infusion, at 0.5, 4, 8 hours post infusion or study drug discontinuation, and on day 28

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Serelaxin in people with Acute Heart Failure, run by Novartis Pharmaceuticals at 10 sites in 4 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 25 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States, Germany, Switzerland, United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Jun 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients With Treatment Emergent Adverse Events, Serious Adverse Events and Death (time frame: through 28 days + 30 days SAE follow up after completion or discontinuation from the study). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jun 2019.
