Main objective
Scope: Therapy, Dose response, Efficacy
To evaluate the efficacy and dose-response relationship of three XXB750 target dose levels compared to placebo in reducing N-terminal prohormone B-type natriuretic peptide (NT-proBNP) from baseline to Week 16 in symptomatic HF patients with LVEF < 50% treated with standard of care, including ACEI/ARB or sacubitril/valsartan.
Secondary objectives 3
- To evaluate the treatment effect of the highest XXB750 target dose level compared to placebo in reducing NT-proBNP from baseline to Week 16 in symptomatic HF patients with LVEF <50% treated with standard of care, including ACEI/ARB or sacubitril/valsartan.
- To evaluate the treatment effect of combined two highest XXB750 target dose levels administered in addition to a background of ACEI/ARB versus conversion from ACEI/ARB to sacubitril/valsartan, in reducing NT-proBNP from baseline to Week 16.
- To evaluate the safety and tolerability of XXB750 up-titration regimens and dose levels.

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 7
- Written informed consent must be obtained before any assessment is performed.
- Male and female outpatients who are ≥ 18 years old.
- Symptom(s) of HF NYHA class II-III at Screening.
- LVEF < 50% (most recent local measurement, made within 6 months prior to or during screening using echocardiography, MUGA, CT scanning, MRI or ventricular angiography is acceptable, provided no subsequent measurement ≥ 50%).
- NT-proBNP ≥ 600 pg/ml if in sinus rhythm or NT-proBNP ≥ 900 pg/ml if in atrial fibrillation/flutter at Screening.
- Receiving an ACEI or an ARB at a stable dose of at least enalapril 10 mg/d or equivalent for at least 4 weeks before Screening or receiving sacubitril/valsartan at a stable dose of at least 49/51 mg bid for at least 4 weeks before Screening.
- Receiving other guideline recommended HF therapies as deemed appropriate by the investigator and that are stable for at least 4 weeks before Screening, unless contraindicated, not tolerated, or not available to patient.
Exclusion criteria 6
- Current acute decompensated HF (exacerbation of chronic HF manifested by signs and symptoms that may require intravenous therapy) or hospitalization for HF within 3 months prior to screening.
- Office systolic blood pressure (SBP) ≥ 180 mmHg or < 105 mmHg at screening or at randomization.
- In subjects with ACEI/ARB medication at screening, previous inability to tolerate any dose of sacubitril/valsartan (as per the investigator's judgment).
- Serum potassium > 5.4 mmol/L at screening.
- Estimated GFR (eGFR) < 30 mL/min/1.73m2 at screening as measured by the CKD-EPI formula.
- Known history of angioedema.
