•1. Subject provides written informed consent prior to study participation
•2. Age at least 18 years or greater
•3. Current New York Heart Association (NYHA) Class II-IV
•4. Left ventricular ejection fraction <=40%, measured by any echocardiographic,
•radionuclide, magnetic resonance imaging (MRI), angiographic, or computerized
•tomography method in the last 12 months (without subsequent measured ejection
•fraction >40% during this interval)
•5. Receiving any dose of a beta blocker (BB) for the treatment of HF or unable
•to tolerate BB (reason documented)
•6. Estimated glomerular filtration rate (eGFR) >=30 mL/min/1.73 m2 at Screening
•(based on a single local laboratory analysis of serum creatinine and
•calculation using the Chronic Kidney Disease Epidemiology Collaboration
•(CKD-EPI) equation; see Section 9.2)
•7. Hyperkalemia at Screening (defined by 2 local serum K+ values of >5.0 mEq/L
•each obtained from a separate venipuncture, e.g., one in each arm or two
•separate venipunctures in the same arm) while receiving ACEi, ARB, ARNi, and/or
•Normokalemia at Screening (defined by 2 local serum K+ >=4.0 <=5.0 mEq/L each
•obtained from a separate venipuncture, e.g., one in each arm or two separate
•venipunctures in the same arm) but with a history of hyperkalemia documented by
•a usual care serum K+ measurement >5.0 mEq/L while on RAASi treatment in the 12
•months prior to Screening leading to a subsequent and permanent dose decrease
•or discontinuation of one or more RAASi medications
•8. Females of child-bearing potential must be non-lactating, must have a
•negative pregnancy test at Screening, and must agree to continue using
•contraception (see Section 9.8) throughout the study and for 4 weeks after
•study completion
•9. With hospitalization for HF or equivalent (e.g., emergency room or
•outpatient visit for worsening HF during which the patient received intravenous
•medications for the treatment of HF) within the last 12 months before Screening
•a) Without atrial fibrillation at Screening, BNP level must be greater than 150
•pcg/mL (18 pmol/L) or N-terminal pro b-type BNP (NT proBNP) must be greater
•than 600 pcg/mL (71 pmol/L)
•b) With atrial fibrillation at Screening, BNP level must be greater than 300
•pcg/mL (35 pmol/L) or NT proBNP must be greater than 1,200 pcg/mL (142 pmol/L)
•Without hospitalization for HF or equivalent (e.g., emergency room or
•outpatient visit for worsening HF during which the subject received intravenous
•medications for the treatment of HF) within the last 12 months before Screening
•a) Without atrial fibrillation at Screening, BNP level must be greater than 300
•pcg/mL (35 pmol/L) or NT proBNP must be greater than 1,200 pcg/mL (142 pmol/L)
•b) With atrial fibrillation at Screening, BNP level must be greater than 600
•pcg/mL (71 pmol/L) or NT proBNP must be greater than 2400 pcg/mL (284 pmol/L)

排除标准

•1. Current acute decompensated HF within 4 weeks before Screening. Subjects
•with a discharge from a hospitalization for acute decompensation of HF longer
•than 4 weeks before Screening may be included
•2. Symptomatic hypotension or systolic blood pressure <90 mmHg
•3. Significant primary aortic or mitral valvular heart disease (except
•secondary mitral regurgitation due to left ventricular dilatation)
•4. Heart transplantation or planned heart transplantation (i.e., currently on a
•heart transplant waiting list) during the study period
•5. Diagnosis of peripartum or chemotherapy-induced cardiomyopathy or acute
•myocarditis in the previous 12 months
•6. Implantation of a cardiac resynchronization therapy device in the previous 4
•weeks before Screening
•7. Restrictive, constrictive, hypertrophic, or obstructive cardiomyopathy
•8. Untreated ventricular arrhythmia with syncope in the previous 4 weeks
•9. History of, or current diagnosis of, a severe swallowing disorder, moderate
•to severe gastroparesis, or major gastrointestinal (GI) surgery (e.g.,
•bariatric surgery or large bowel resection)
•10. A major CV event within 4 weeks prior to Screening, including acute
•myocardial infarction, stroke (or transient ischemic attack), a life
•threatening atrial or ventricular arrhythmia, or resuscitated cardiac arrest
•11. Note: This exclusion criterion is included in the new Inclusion Criterion 9
•12. Liver enzymes (alanine aminotransferase, aspartate aminotransferase) >5
•times upper limit of normal at Screening based on the local laboratory
•13. Diagnosis or treatment of a malignancy in the past 2 years, excluding non
•melanoma skin cancer and carcinoma in situ of the cervix, prostate cancer with
•Gleason score <7, or a condition highly likely to transform into a malignancy
•during the study
•14. Presence of any condition (e.g., drug/alcohol abuse; acute illness), in the
•opinion of the Investigator, that places the subject at undue risk, or prevents
•complete participation in the trial procedures, or potentially jeopardizes the
•quality of the study data
•15. Use of any investigational product for an unapproved indication within 4
•weeks prior to Screening or currently enrolled in any other type of medical
•research judged not to be scientifically or medically compatible with this study
•16. Known hypersensitivity to patiromer (RLY5016) or its components
•17. Note: This exclusion criterion is modified and partially incorporated in
•Exclusion Criterion 18
