Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the safety and tolerability of single doses of REGN5381 in patients with heart failure with evidence of congestion.;Secondary Objective: • Evaluate the effects of single doses of REGN5381 on hemodynamic parameters • Evaluate the effects of REGN5381 on a clinical biomarker of heart failure severity • Characterize the pharmacokinetics (PK) of single doses of REGN5381 • Assess the immunogenicity of REGN5381;Primary end point(s): Incidence and severity of treatment-emergent adverse events (TEAEs);Timepoint(s) of evaluation of this end point: Through the end-of-study (EOS) visit up to 126 days | — |
Secondary
| Measure | Time frame |
|---|---|
| Timepoint(s) of evaluation of this end point: 1-6: Over 6 hours post-dose administration 7-10: Over the first 6 hours, 24 hours post-dose administration (day 1), through the EOS visit up to 126 days 11: To 6 hours, 24 hours post-dose administration (day 1), through the EOS visit up to 126 days 12-13: Through the EOS visit, up to 126 days;Secondary end point(s): 1: Change from baseline in pulmonary capillary wedge pressure (PCWP) 2: Change from baseline right atrial pressure (RAP) 3: Change from baseline cardiac output (CO) 4: Change from baseline systemic vascular resistance (SVR) 5: Change from baseline mean pulmonary artery pressure (mPAP) 6: Change from baseline pulmonary vascular resistance (PVR) 7: Change from baseline in systolic blood pressure (SBP) 8: Change from baseline in diastolic blood pressure (DBP) 9: Change from baseline in mean arterial pressure (MAP) 10: Change from baseline in pulse rate (PR) 11: Change from baseline in N-terminal pro-brain natriuretic peptide (NT-proBNP) 12: Concentrations of REGN5381 in serum 13: Immunogenicity, as measured by anti-drug antibodies (ADA) to REGN5381 | — |
