Abstract
Patients with heart failure experience limitations in daily activity and poor quality-of-life. Prospective surveillance of health-related quality-of-life supplemented traditional death and hospitalization outcomes in the multinational, randomized, double-blinded CHART-1 clinical trial that assessed cardiopoiesis-guided cell therapy in ischemic heart failure patients with reduced left ventricular ejection fraction. The Minnesota Living with Heart Failure Questionnaire (MLHFQ), a Food and Drug Administration qualified instrument for evaluating therapeutic effectiveness, was applied through the 1-year follow-up. Cell treated (n = 109) and sham procedure (n = 140) cohorts reported improved MLHFQ scores comparable between the 2 study arms (mean treatment difference with baseline adjustment -3.2 points, P = .107). Superiority of cell treatment over sham in betterment of the MLHFQ score was demonstrated in patients with pre-existing advanced left ventricular enlargement (baseline-adjusted mean treatment difference -6.4 points, P = .009). In this highly responsive subpopulation, benefit on the MLHFQ score paralleled reduction in death and hospitalization post-cell therapy (adjusted Mann-Whitney odds 1.43, 95% CI, 1.01-2.01; P = .039). The potential of cell therapy in addressing the quality-of-life dimension of heart failure requires further evaluation for disease relief.

Efficacy and safety of serelaxin when added to standard of care in patients with acute heart failure: results from a PROBE study, RELAX-AHF-EU. Eur J Heart Fail 2019; 21:322-333. [PMID: 30604559 DOI: 10.1002/ejhf.1368] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2018] [Revised: 08/23/2018] [Accepted: 10/24/2018] [Indexed: 12/13/2022] Open
Abstract
AIM Serelaxin is a recombinant human relaxin-2 hormone, which confers receptor-mediated vasodilatation in a tissue-specific fashion. The RELAX-AHF-EU study assessed the effect of serelaxin when added to standard-of-care (SoC) therapy on worsening heart failure (WHF)/all-cause death through Day 5 in patients hospitalised for acute heart failure (AHF) in Europe. METHODS AND RESULTS This multicentre, prospective, randomised, open-label, blinded-endpoint validation study enrolled hospitalised AHF patients and randomised (2:1) eligible patients (mild-to-moderate renal impairment and systolic blood pressure ≥ 125 mmHg) within 16 h of presentation with signs/symptoms of AHF, to receive 48 h intravenous infusion of 30 μg/kg/day serelaxin + SoC or SoC alone. The primary endpoint was adjudicated WHF/all-cause death through Day 5. Of 3183 patients targeted, 2666 were randomised when the study was terminated early by the sponsor due to the neutral results of the pivotal RELAX-AHF-2 study. Adjudicated WHF/all-cause death through Day 5 was significantly reduced in the serelaxin + SoC vs. SoC group (5.0% vs. 6.9%; hazard ratio 0.71; 95% confidence interval 0.51-0.98; P = 0.0172) (absolute risk reduction 1.9%, number needed to treat 53). The difference between treatment groups was not significant for WHF/all-cause death/heart failure rehospitalisation through Day 14 and length of hospital stay. A significantly smaller proportion of patients in the serelaxin + SoC vs. SoC group experienced persistent heart failure signs/symptoms at each visit until Day 4, or renal deterioration through Day 5 (all P ≤ 0.01). Overall incidence of treatment-emergent adverse events was comparable between treatment groups. Hypotension and decrease in haemoglobin/haematocrit were more frequent in the serelaxin + SoC group. CONCLUSION When added to SoC, serelaxin reduced adjudicated WHF or all-cause death through Day 5 in AHF patients. The results from this open-label study should be considered in the context of the totality of the double-blind, randomised evidence on serelaxin in AHF.
