Official title

A Double-blind,Randomized, Placebo-controlled Study to Assess Exercise Tolerance After Iron Repletion With Ferric Derisomaltose (Monoferric®) IV Compared to Placebo in Heart Failure With Preserved Ejection Fraction and With Iron Deficiency.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The primary objective of this study is to determine if the correction of functional iron deficiency by administering a single dose of intravenous iron (ferric derimaltose or Monoferric®) in participants with heart failure with preserved ejection fraction (HFpEF) will improve exercise capacity as measured by the change in peak oxygen uptake (peak VO2) from baseline to 12 weeks.
