A Double-Blind Pharmacokinetic Interaction Study Evaluating the Effect of a Single IV Infusion of GGF2 or Placebo on Midazolam Pharmacokinetics in Patients With Heart Failure

This drug-drug interaction (DDI) study evaluates the potential effect of intravenously administered GGF2 on the elimination kinetics of midazolam.

Inclusion criteria
