A study to determine the most appropriate dose of MK7418 in heart failure patients presenting with symptoms of volume overload requiring increased diuretic doses.

Condition Intervention Phase
Congestive Heart Failure
Renal Impairment
Drug: rolofyline
Drug: Comparator Placebo (unspecified)
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, Placebo Controlled Dose-Ranging Study of The Effects of MK7418, Both as Monotherapy and in Combination With Furosemide, On Diuresis and Renal Function in Patients With Congestive Heart Failure (CHF) And Renal Impairment Treated With Oral Loop Diuretics Who Require Hospitalization For Fluid Overload

Primary Outcome Measures:
  • To measure the diuretic effect of a single dose of the study medication (monotherapy) over six hours compared to a single dose of IV placebo (monotherapy) in CHF patients with renal impairment [ Time Frame: 30 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To determine the optimal dose range of intravenous (IV) study medication combination with IV furosemide, with or without other diuretics, in preventing deterioration of renal function in CHF patients [ Time Frame: 30 Days ] [ Designated as safety issue: No ]

Enrollment: 160
