Brief TitleEvaluation of RLY5016 in Heart Failure Patients
Official TitleA Multicenter, Randomized, Double-blind, Placebo-Controlled, Parallel-Group, Multiple-Dose Study to Evaluate the Effects of RLY5016 in Heart Failure Patients
Brief Summary
The purpose of this study is to assess the effects of RLY5016 on serum potassium in heart
failure patients. This study will also assess the safety and tolerability of RLY5016 in
heart failure patients.
Detailed Description
Double-blind, randomized, placebo-controlled, parallel-group, multiple-dose study in up to
270 congestive heart failure patients. Depending on the outcome from the initial cohort of
100 patients (Part 1), a second cohort of 170 patients may be enrolled (Part 2).

Part 1:

One hundred eligible patients will be randomly assigned to receive RLY5016 (30 g/day) or
placebo for 28 days. All patients will also receive spironolactone; the initial
spironolactone dose is 25 mg daily and will be increased to 50 mg daily for patients who
have a serum potassium ≤ 5.1 mEq/L on treatment Day 14. Study visits will be scheduled for
treatment Days 3, 7, 14, 17, 21 and 28.

A safety follow-up contact will be made 7 days after administration of last dose of study
drug.

An interim analysis will be conducted after data from Part 1 are available.

Part 2:

One hundred seventy eligible patients will be randomly assigned to one of two RLY5016
treatment groups (15 or 60 g/day) or placebo for 28 days. All patients will also receive
spironolactone for 28 days; the initial spironolactone dose is 25 mg daily and will be
increased to 50 mg daily for patients who have a serum potassium ≤ 5.1 mEq/L on treatment
Day 14. Study visits will be scheduled for treatment Days 3, 7, 14, 17, 21 and 28.

A safety follow-up contact will be made 7 days after administration of last dose of study
drug.

Eligibility Criteria
Inclusion Criteria:

- Heart failure patients clinically indicated to receive spironolactone therapy, with
serum potassium levels of 4.3 - 5.1 mEq/L AND chronic kidney disease (GFR <60 mL/min)
OR documented history of hyperkalemia within the last 6 months

- Females of child-bearing potential must be non-lactating, must have a negative serum
pregnancy test at screening, and must have used a highly effective form of
contraception for at least 3 months before study drug administration, during the
study, and for one month after study completion

- Male patients and/or their female partners of child-bearing potential must use a
highly effective form of contraception during the study and for 3 months after study
completion

- Must sign informed consent document

Exclusion Criteria:

- History of bowel obstruction, swallowing disorders, severe gastrointestinal disorders
or major gastrointestinal surgery

- Uncorrected hemodynamically significant primary valvular disease, known obstructive
or restrictive cardiomyopathy, uncontrolled or hemodynamically unstable arrhythmia

- Coronary-artery bypass graft, percutaneous intervention (e.g. cardiac,
cerebrovascular, aortic), or major surgery including thoracic and cardiac, within 3
months prior to baseline or anticipated need during study participation

- Heart transplant recipient, or anticipated need for transplant during study
participation

- Any of the following events having occurred within 3 months prior to baseline:
unstable angina as judged by the Investigator, unresolved acute coronary syndrome,
transient ischemic attack or stroke

- Current dialysis patient, or anticipated need for dialysis during study participation

- Prior kidney transplant, or anticipated need for transplant during study
participation

- Metastatic, late-stage or end-stage cancer with < 12 months life expectancy

- History of alcoholism or drug/chemical abuse within 1 year

- QTcB interval > 500 msec (Bazett's correction formula)

- Sustained systolic blood pressure > 170 or < 90 mmHg

- Liver enzymes (ALT, AST) > 3 times upper limit of normal

- Use of oral cardiac medications (including loop and thiazide diuretics) that have not
been stable for at least 21 days prior to baseline and are not anticipated to remain
stable during study participation

- Use of any IV cardiac medications within 21 days prior to baseline, or their
anticipated need during study participation.

- Current use of polymer-based drugs (e.g. Renagel, Kayexalate, Welchol, Colestid),
other phosphate binders or potassium binders, calcium supplements, antacids (eg TUMS,
Maalox), or their anticipated need during study participation

- Use of aldosterone antagonist in the last 30 days prior to baseline, unless was
discontinued due to hyperkalemia

- Use of potassium sparing medication and/or potassium supplements in the last 30 days
prior to baseline

- Use of any investigational medication, 30 days or 5 half-lives whichever is longer,
prior to baseline

- Patients who have taken investigational product in this study, or a previous RLY5016
study

- Inability to consume the study medication, or, in the opinion of the Investigator,
inability to comply with the protocol

- In the opinion of the Investigator, any medical condition, uncontrolled systemic
disease, serious intercurrent illness, or extenuating circumstance occurring or
persisting, within 30 days prior to baseline, that would significantly decrease study
compliance or jeopardize the safety of the patient or affect the validity of the
trial results
