  • Change From Baseline in First 24hr Urinary Sodium (UNa) (Part 1) [ Time Frame: Baseline (Day -1) and 0-24 hours postdose on Treatment Day 1 of each treatment period ]
    Urine was collected at Treatment Day -1 and Treatment Day 1 at 0-2, 2-4, 4-6, 6-8, 8-12, 12-24 hour. The 24-hour cumulative natriuresis will be estimated by the amount of sodium excreted into urine over 24 hour period postdose, where amount of sodium is the product of sodium concentration and the volume of urine. The change from baseline in UNa from baseline (Treatment Day -1) and 24 hours post-dose on Treatment Day 1 were calculated.
  • N-terminal Pro B-type Natriuretic Peptide (NT-proBNP) Values at 24 Hours Post Last Morning Dose of Each Period (Part 2) [ Time Frame: Day 15 for Periods 1, 2, and 3; Day 29 for Period 4 ]
    B-type natriuretic peptide (BNP) is a substance secreted from the ventricles or lower chambers of the heart in response to changes in pressure that occur when heart failure develops and worsens. The level of BNP in the blood increases when heart failure symptoms worsen, and decreases when the heart failure condition is stable. The BNP level in a person with heart failure is higher than in a person with normal heart function. Levels of BNP levels were assessed 24 hours post last morning dose of study drug for each treatment period.

A Study of MK-7145 in Participants With Renal Insufficiency (Part I) and Heart Failure With Renal Insufficiency (Part II) (MK-7145-011)
A Two Part, Open-label, Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of MK-7145 in Patients With Renal Insufficiency (Part I) and Heart Failure With Renal Insufficiency (Part II)

Part I is a 3-period, active comparator-controlled, fixed sequence study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of MK-7145 compared to furosemide in participants with moderate-to-severe renal insufficiency (RI) without heart failure (HF). Primary hypothesis for Part I is that at least one well-tolerated dose of MK-7145 will produce a greater 24hr urinary excretion of sodium (UNa) on the 1st day of MK-7145 dosing than 80 mg furosemide (on the 1st day of furosemide dosing) in participants with moderate-to-severe RI. If MK-7145 is safe at natriuretic doses in RI in Part I of this study, MK-7145 will be investigated in participants with heart failure (HF) and RI (Part II).

Part II is 4 period, fixed sequence, active comparator controlled (in Period 1), titration (in Periods 2, 3 and 4) study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of a titration regimen of MK-7145 compared to an optimized stable maintenance regimen of furosemide or torsemide in participants with New York Heart Association (NYHA) Class II and III heart failure and moderate or severe renal insufficiency. The primary hypothesis for Part II is that at least one dose of MK-7145, titrated according to a fixed dose titration regimen, will be associated with a reduction in N-terminal pro-brain natriuretic peptide (NT-proBNP) compared to furosemide or torsemide (at 24 hours post morning dose on the last dosing day of each period) in participants with NYHA class II/III HF with moderate or severe RI.
