Impact of Intravenous Iron Repletion On Mechanisms of Exercise InTolerance in HFpEF (IRONMET-HFpEF) (NCT04945707)

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

๐Ÿ”ต Active, Not Recruiting Phase4 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: Massachusetts General Hospital

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

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 Monoferricยฎ) 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.
