- Patients with hematocrit <25%, or a history of blood transfusion within the 14 days prior to screening, or active life-threatening GI bleeding.
- Known hepatic impairment (as evidenced by total bilirubin > 3 mg/dL, or increased ammonia levels, if performed) or history of cirrhosis with evidence of portal hypertension such as varices.
- Significant, uncorrected, left ventricular outflow obstruction, such as obstructive hypertrophic cardiomyopathy or severe aortic stenosis (i.e., aortic valve area <1.0 cm2 or mean gradient >40 mmHg on prior or current echocardiogram), and severe mitral stenosis
- Severe aortic insufficiency or severe mitral regurgitation for which surgical or percutaneous intervention is indicated.

About this study
Official title: A Multicenter, Randomized, Double-blind, Placebo-controlled Phase III Study to Evaluate the Efficacy, Safety and Tolerability of Serelaxin When Added to Standard Therapy in Acute Heart Failure Patients
The purpose of the study was to evaluate the efficacy, safety and tolerability of intravenous infusion of serelaxin, when added to standard therapy, in acute heart failure (AHF) patients.
Read the detailed description
This Phase IIIb outcome study in AHF patients was designed as a multicenter, randomized, double-blind, placebo-controlled, event-driven study in order to assess the efficacy, safety and tolerability of intravenous infusion of serelaxin or placebo. The AHF patients randomized to either serelaxin or placebo in the study were followed for a period of 180 days, and were required to receive standard-of-care background HF management during both the index hospitalization and post discharge according to regional or local guidelines/institutional standards.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RLX030Drug
1 mg/mL solution in 6 mL vials
PlaceboDrug
Matching placebo solution to serelaxin
| Study group | Role | What they receive |
|---|---|---|
| Serelaxin (RLX030) | Experimental | Participants received continuous intravenous infusion of serelaxin 30 ug/kg/day for 48 hours. Receives: Drug: RLX030 |
| Placebo | Placebo comparator | Participants received continuous intravenous infusion of matching placebo to serelaxin for 48 hours. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Confirmed Cardiovascular (CV) Death Through Day 180
The percentage of participants with an adjudicated CV death through day 180 was assessed.
Measured: 180 days
Percentage of Participants With Worsening of Heart Failure (WHF) Through Day 5
The percentage of participants with WHF through day 5 was assessed.
Measured: Day 5
Secondary outcomes (8)
Percentage of Participants With All-cause Death Through Day 180
The percentage of participants with all-cause death through day 180 was assessed.
Measured: 180 days
Length of Total Hospital Stay (LOS) During the Index Acute Heart Failure (AHF) Hospitalization
Length of stay was defined as the index hospitalization discharge date and time minus the baseline date and time plus 1 day.
Measured: 180 days (Participants still in the hospital at Day 60 were censored at Day 60)
Percentage of Participants With First Occurrence of Adjudicated CV Death or Adjudicated Re-hospitalization

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing RLX030 in people with Acute Heart Failure, run by Novartis Pharmaceuticals at 540 sites in 35 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 8 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: finished, as of the sponsor's last update on 30 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 540 sites in United States, Germany, Argentina, Russia, Italy and 30 more countries. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 30 Mar 2018). 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?
Percentage of Participants With Confirmed Cardiovascular (CV) Death Through Day 180 (time frame: 180 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01870778, which also lists 9 linked publications.
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 30 Mar 2018.
