Study summary

Two doses of relaxin will be compared to placebo for the treatment of patients with decompensated CHF

Read the detailed description

Pilot clinical data suggest that recombinant human relaxin may be effective in treating patients with decompensated CHF. This study will randomize patients in blinded manner to one of two doses of intravenous relaxin or placebo. Serial evaluations will include cardiac and renal function, as well as safety and tolerability.

What researchers measure

Primary outcomes

  1. Cardiac hemodynamics

    Time frame: Baseline through 27 hours post-infusion or discharge from the hospital.

Secondary outcomes

  1. Renal function

    Renal function was to be assessed by evaluation of serum creatinine, creatinine clearance, BUN, uric acid, GFR, RBF, urine output, sodium clearance, and body weight.

    Time frame: Baseline through Day 10

  2. Safety and Tolerability assessed by number of patients with adverse events (AEs)

    Time frame: Baseline through Day 30
